I was looking for this functionality today and stumbled across the referenced thread. It was, coincidentally, updated today:Hello,Thanks for your input. I have submitted a feature request on your
behalf to export WAF events to S3 for long term analysis.Best Regards, albertpatawsThe lack of this feature strikes me as being almost as odd as the fact that I can't change timezones for graphs.ShareFollowansweredSep 11, 2017 at 18:57bstovallbstovall12111 silver badge1010 bronze badgesAdd a comment|

How do you route AWS Web Application Firewall (WAF) logs to an S3 bucket? Is this something I can quickly do through the AWS Console? Or, would I have to use a lambda function (invoked by a CloudWatch timer event) to query the WAF logs every n minutes?UPDATE:
I'm interested in the ACL logs (Source IP, URI, Matches rule, Request Headers, Action, Time, etc).UPDATE (05/15/2017)AWS doesn't provide an easy way to view/parse these logs. You can get a "random sample" via the get-sampled-requests command. Which isn't acceptable...Gets detailed information about a specified number of requests--a
sample--that AWS WAF randomly selects from among the first 5,000
requests that your AWS resource received during a time range that you
choose. You can specify a sample size of up to 500 requests, and you
can specify any time range in the previous three hours.http://docs.aws.amazon.com/cli/latest/reference/waf/get-sampled-requests.htmlAlso, I'm not the only one experiencing this issue either:https://forums.aws.amazon.com/thread.jspa?threadID=220202

I'm assuming 'Oauth2 Server' in your question means the thing that validates tokens. You don't state if your app is actually issuing tokens, or what type of tokens are issued.Best option is probably subjective, but my preference has always been to use Custom Authorizers, as this is then a re-usable component for other resources.Swagger imports into API Gateway aside, you can manage authorization in your app if you wanted to, it just becomes the first thing you deal with when a new request is received, just make sure the authorization header is mapped in API Gateway to head downstream.ShareFollowansweredJun 5, 2018 at 15:45K MoK Mo2,12599 silver badges1616 bronze badgesAdd a comment|

I’m planning on building a user management Java API and deploy it in Wildfly. The API specification will be done using Swagger.Then I will create a Docker image with the Wildfly + application and then create a container from that image on AWS ECS (EC2 Container Service).The next step is to import the API’s Swagger specification into AWS API Gateway and forward the requests to the created AWS ECS container.My question. What is the best option to implement an OAuth2 server:Create it in a Lambda Function and use it as a Custom Authorizer in AWS API Gateway?Create it on a new Java application (on the same or new Wildfly container), therefore not using the AWS API Gateway’s Custom Authorizer option? Is this even possible, since the requests will be received from AWS API Gateway? I ask this because when trying to import a Swagger specification with and OAuth2 security implementation, AWS API Gateway gives the following error:Your API was not imported due to errors in the Swagger file.
Unsupported security definition type 'oauth2' for 'oauth'. Ignoring.As a side note, since all the future clients of the API will be developed by myself, I’m planning on using the Resource Owner Password Credentials Grant on my OAuth2 server.

I've done this before a long time ago, but now it's not working... :)I am trying to use EBExtensions in an ElasticBeanstalk application. I created a vanilla Elastic Beanstalk environment with no configuration beyond the defaults. I gave it an application version that had a directory structure like the following:.ebextensions
40testextension.config
app.js
other filesThe important part is that I have a folder called .ebextensions at the root of my deployable artifact, which is where I believe it should be located.The 40testextension.config file inside that file has the following contents:files:
"/home/ec2-user/myfile" :
mode: "000755"
owner: root
group: root
content: |
# This is my file
# with contentI uploaded that version when creating the environment, and the environment created successfully. But when I look for that file, it is not present. Furthermore, when do a recursive grep for that ebextension file name in the logs at /var/log, I only get one result:./eb-activity.log: inflating: /tmp/deployment/application/.ebextensions/40testextension.configHaving looked at the logs, it seems that the file is present when the artifact gets pulled down to the host, but the ebextension never gives any indication of running.What am I missing here? I've done this in the distant past and things have worked very nicely, but this time I can't seem to get the thing to be executed by the Beanstalk deploy lifecycle.

I believe you might have some static variables there. In Java environment, AWS-Lambda keeps the static variables in memory across multiple lambda executions. So If you have a static map and you add variables to it with each lambda execution, It stays in memory. This might be the case for node.js too.ShareFollowansweredJul 13, 2017 at 16:07super7egazisuper7egazi75311 gold badge88 silver badges2323 bronze badgesAdd a comment|

I had similar problem with OVA images exported from VirtualBox. In my case converting it toraw imageformat worked. So if you are using VirtualBox, import the OVA to it, and then convertVDIstorage drive toraw. For example:VBoxManage clonehd "/mnt/b/VirtualBox VMs/ub.vdi" ./ub.img --format rawThen you uploadub.imgto S3, and use that in yourcontainers.jsonfile foraws ec2 import-imagecommand. For example:[

We're using Auth0 to give (federated) users access to Auth0 (we've followed these instructions for setup:https://auth0.com/docs/integrations/aws#sso-with-the-aws-dashboard)In Auth0 we've setup a simple rule system where the federated user's group membership maps to one of two different IAM roles, which gives the user either full access or read-only access (or no access at all) in the aws console.However, I'm struggling to see how I can provide federated users with the means to get an access key id/secret linked to their account. Our wishlist is:The access key id/secret is unique per federated user, and as such is void if the federated user is deleted from the identity provider.I could manually provision a IAM role per federated user and link each user to his/her "personal" IAM role, but I'd obviously prefer not to.All in all I guess I'd like there to be a "linked" IAM user representing each federated account.So I guess my question is: How do allow my federated users access to personal access key id's in aws?

I had the same problem with a NodeJS Elastic Beanstalk app. However, I was able to get around it by updating the Listener/Certificate settings via the AWS EC2 console (https://console.aws.amazon.com/ec2/), via the Load Balancers section (under LOAD BALANCING).I was updating the certificate for a staging version of a cloned environment.

Your best bet for this will be to use astack set in CloudFormation.AWS CloudFormation StackSets extends the functionality of stacks by
enabling you to create, update, or delete stacks across multiple
accounts and regions with a single operation. Using an administrator
account, you define and manage an AWS CloudFormation template, and use
the template as the basis for provisioning stacks into selected target
accounts across specified regions.With a stack set, you can specify the accounts and regions to which you want to deploy your lambda. You will likely want to put the lambda code in an S3 bucket that you can then reference from your CloudFormation template.Then it is easy (and simple) to deploy to a new region--just add that region to the stack set.ShareFollowansweredAug 25, 2020 at 15:54ShawnShawn8,64755 gold badges3838 silver badges6464 bronze badgesAdd a comment|

Your answer may be in thisOpenVPN Support thread. I'm running into the same issue. From what I gather, when you're connected over vpn, public IPs and DNS names won't resolve. You can connect to other EC2 instances easily using private IPs. But the RDS instance's IP is not static, so it must be resolved using it's host name. The solution apparently is to make your OpenVPN server use the Amazon DNS server, so that it can resolve the RDS instance by its host name.ShareFollowansweredNov 19, 2017 at 20:36Paul SiersmaPaul Siersma2,10611 gold badge2222 silver badges2525 bronze badgesAdd a comment|

In the same VPC I have a RDS instance and another EC2 instance in a private subnet.I have devices that connects to the VPN server and I have configured that they can communicate with each-other and with the private EC2 too. But I can't make them to communicate with the RDS instance.I have configured the Security Group of the RDS to allow all inbound traffic from the SG of both EC2, tried to allow even All Traffic from 0.0.0.0/0 a still VPN clients can't communicate with the RDS. I see that RDS can communicate inside the VPC but not outside it.

I'm just starting with the AWS...I have 1EC2 Instance, which is running WordPress (WordPress powered by Bitnami image from the Marketplace -https://aws.amazon.com/marketplace/pp/B007IP8BKQ).
Everything works fine, I can access both front and back-end of the WP installation running from standardHTTP.The problem starts when I connect the Instance to the ELB and I'm trying to access the site via theHTTPS.I've run through the process of setting up the SSL certificate using the ACM and applied the cert to the ELB. I've also got the 443 and 80 port enabled on the security group for the EC2 instance. The port forwarding on the ELB is set up for both 443 and 80 to go to 80 and my WP config file is set up to check the HTTP_X_FORWARDED_PROTOheader to stop WP getting into an infinite redirect loop.I think this is all working fine, as I can access the site via the HTTPS and browse the pages. However, when I attempt to log in I am redirected to HTTP and to solve this problem I have set WP site URL and WP home URL to HTTPS. This then results in numerous 503 errors (503 Service Unavailable: Back-end server is at capacity). From the AWS Dashboard, I can see the Instance is running just fine.I've researched quite a lot to make sure I have everything set up correctly (some threads I've come across -Link 1Link 2) and everything seems fine (but something is obv wrong).Any suggestions on how to get the ELB to work?

I'v newer deployed to amazon (and havesmallexperience with Spring) but i see some ways to solve it:Just use Apache Zookeeper. Create ephemeral-sequential nodes in zookeeper for each node. When i'ts scheduled time and node is first in that queue - remove node from queue, add node again and start your job (Apache Curator Framework has all functionality you need to implement it in your code)Use Hazelcast queues (same logic). Benefits: hazelcast could be used in embedded mode. Minuses: not sure about hazelcast discovery abilities in amazon, as for my experience - hazelcast is much less stable than zookeeper.Other way - if you have any "instance id" on each instance you could start job if start time is reachedANDinstanceId.hashcode() % dayOfMonthNumber == 0ShareFolloweditedAug 19, 2016 at 21:11answeredAug 18, 2016 at 21:18Frut DzentreadyFrut Dzentready13277 bronze badges3Let me try to develop a solution using these methods.–Pravin UmamaheswaranAug 19, 2016 at 14:33just tell me if you need any assistance–Frut DzentreadyAug 19, 2016 at 21:061@PravinUmamaheswaran Were you able to develop a solution to run the job only in one of the instance?–Jitendra KumarJul 22, 2022 at 10:55Add a comment|

For the moment, you may have to rely on thelist of public IP address ranges for AWS, allowing traffic bound for all the CIDR blocks associated with your region.Part of design for resiliency of much of what AWS does relies on the ability of their service endpointsnotto depend on static address assigments and instead to use DNS... but their service endpoints should always be on addresses associated with your region, since very few services violate their practice strict regional separation of service infrastructure.(CloudFront, Route 53, and IAM do, maybe others, but these are provisioning endpoints, not operational ones. These provisioning-only endpoints do not need to be accessible for most applications to function normally.)ShareFollowansweredJul 14, 2016 at 11:26Michael - sqlbotMichael - sqlbot174k2727 gold badges367367 silver badges440440 bronze badges11good answer Michael, did not know about publicly available list of AWS address ranges, this is really handy.–b.b3rn4rdJul 14, 2016 at 11:33Add a comment|

every SNS message contain a "mail" part with the messageIdsee. If you are sending a mail you receive as the only response the messageIdsee.
so I store all the messageId together with information I later maybe need if that mail bounces or gets complaints and if I receive a bounce I can query all the information with the given messageId.

Currently we are using Mandrill to send our emails, when ever Mandrill detects a bounce we get the original headers along with the bounce or a subaccount where the email was send from.In Amazon SES we are getting the notifications through SNS thats no problem but besides the email from the user we get no original information back. So we have no idea what email campaign the user bounced on etc.Anybody that knows how to handle this?

My current application is updating JSON files on the amazon elastic beanstalk server. Is there any way to download the current files on the server or access those JSON files??Just wondered if I can access them before restructuring my server to host those files elsewhere or on a DB.

I am trying to import all my listing data in my local website, but I could not find proper API to get all product related information from 1 api call.- Product images- Product variations- Product attributesCurrently I am using "_GET_MERCHANT_LISTINGS_DATA_' report and GetMatchingProductRequest to achieve that but not get all information which I can see on Amazon selling website.. Can anyone suggest is there any proper API to do so?2) Real time Order/Product Updates - When any new order came in my amazon selling account I like to received real time order update to my given webservice URL. is that possible in Amazon? I have read spec but not find any relavant information to achieve that..
Can anyone please suggest is that possible in Amazon MWS api?

It doesn't seem to be a VPC problem, but more a problem of package that is not in the lambda.In python, the best way is to install your packages in your lambda folder before compressing all in the .zip :$ pip install YOUR_MODULE -t YOUR_LAMBDA_FOLDER(And I don't knowpypyodbcbutpymsqlis working for me.)

my app does some http request and insert the result into sql server db on daily basis. sql server is on amazon's rds service, i use default-vpc settings.When i try to use it in aws lambda (packaged as it defined on the aws-lambda documentation), it gives following error:module initialization error: 'ODBC Library is not found. Is
LD_LIBRARY_PATH set?'I use pypyodbc as python mssql module.Do i need to setup odbc library manually?Attached role includes the policiy:AWSLambdaVPCAccessExecutionRoleEdit: i tried to use ceodbc and pyodbc, unable to find module "" error raised. (installed in virtualenv with ceodbc whl file, pyodbc with pip)
NOTE: those two has .pyd file extensions in root level, since they are also in the site-packages folder. I guess amazon lambda doesn't include pyd file while executing.Edit2: followed these steps, got same error.https://docs.aws.amazon.com/lambda/latest/dg/vpc-rds-create-rds-mysql.html

OK, so I figured it out and thought I'd put the answer up here in case it is useful to anyone else.As I suspected the problem was the curl version. In order for the line which tells curl which version to use to take affect I needed to be on curl version 7.34 or higher.curl_setopt($ch, CURLOPT_SSLVERSION, 6);So how do you upgrade the curl version? Well there was a big upgrade button on the environment's main page to upgrade the version of Linux running on my instances so I clicked on that it upgraded curl at the same time. I now have curl version 7.38 and its using TLS v1.2 as I wanted.
|
I use this PHP function below to use curl to contact an outside APIfunction api_post($url, $data = array()) {
global $api_key;
global $password;
$data = json_encode($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_SSLVERSION, 6);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_MAXREDIRS, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Accept: application/json'
));
curl_setopt($ch, CURLOPT_USERPWD, $api_key . ':' . $password);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$response = curl_exec($ch);
return $response;
}The api that I m communicating with is about to insist on using tls v1.2 which is a good thing except for some reason my code is using version 1.0.It is fine if I do it from my local server but on the production server (An Amazon Web Services EC2 instance on AWS Elastic Beanstalk) it is not. I guess it has something to do with my server setup but I have no idea what or how to fix it.Here is the curl section from my PHPinfo. Maybe I need to upgrade it or something? But how would I do this?
|
USing TLS v1.2 for Curl On Amazon AWS
|
Not sure when this changed, but currently you can trigger TLS enforcement viaConfiguration Sets, as mentionedhere.You configure whichconfiguration setto use per email, for example adding a custom header to your email when sending via SMTP:X-SES-CONFIGURATION-SET: [NameOfConfigSet]
|
I am sending transnational emails using AWS SES and I want them to be
transferred over a secure connection only.By this I mean that if the receiving server does not support TLS I do not want the email to be sent at all.The FAQ on SES states:Q: Does Amazon SES send email over an encrypted connection using Transport Layer Security (TLS)?A: Yes. If the receiving mail server advertises the STARTTLS extension, Amazon SES will attempt to upgrade the connection to a TLS connection. If that fails, Amazon SES will fall back to plain text.(see here)Is there anyway to avoid sending emails over non secure connections?

For EC2 you need to install the AWS Plugin that is provided by elasticsearch. Once plugin is installed, you need to generate secret-key and access-key from EC2.Thislink should help you generate the required keys.
After this you need to configure following settings in your elasticsearch.yml : network.host:ec2,network.publish_host: "", discovery.type: ec2,cloud.aws.access_key: , cloud.aws.secret_key: ,discovery.ec2.groups: ,discovery.ec2.host_type: "public_ip", discovery.ec2.ping_timeout: "10s"This should get you up and running. Connect from your client using the ip address of your machine.

I have elasticsearch running on EC2 (Fedora),I am unable to connect externally using the public ip or hostname.ElasticSearch starts correctly and I can access locally on the machine using: curl -XGEThttp://localhost:9200{

}And I do follow all the steps explained here:elasticsearch on Ec2 cannot hit public IP(timeout)likeDo what TJ said in his comment, + restart the instance. I wasn't sure if this was/is necessary, but I did it for good measure.I made sure that the following is set in the elasticsearch.yml file: a. http.enabled: true b. http.cors.enabled: true c. http.cors.allow-origin: "*"Restarted elasticsearch (service elasticsearch restart)I can connect kibanaBut I can't connect to elasticsearchmy inbound and outbound are wide open for this instance:this is my elasticsearch.yml file

I have an AWS Lambda function which is logging errors. Errors are logged as such:console.error(err);I'm trying to create a Cloudwatch filter which uses their JSON log filtering syntax:{ $.errorType = "ValidationException" }I can see the error in the log2015-11-24T20:26:02.852Z 76800706-2d78-45ed-9068-46ccccafe6af

"errorType": "ValidationException",

}Is there some sort of special setup or manual logging into CloudWatch required to support the JSON filter syntax? I cannot find any info in the CloudWatch docs.Docs:http://docs.aws.amazon.com/lambda/latest/dg/nodejs-prog-model-logging.htmlhttp://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/FilterAndPatternSyntax.html#d0e19372

Put your environment variable in a file:export AWS_ACCESS_KEY=
export AWS_SECRET_KEY=save the file in ~/.vars in the remote host and then in your playbook.- name: Describe instances

The AWS CLI command tasks in Ansible playbooks work fine form command line if AWS credentials are specified as environment variables as per boto requirements. More info can be found hereEnvironment Variables.
But they fail to run in Tower because it exports another set of env. vars:AWS_ACCESS_KEY
AWS_SECRET_KEYIn order to make them work in Tower just add the below in task definition:environment:
AWS_ACCESS_KEY_ID: "{{ lookup('env','AWS_ACCESS_KEY') }}"
AWS_SECRET_ACCESS_KEY: "{{ lookup('env','AWS_SECRET_KEY') }}"e.g. this task:- name: Describe instances
command: aws ec2 describe-instances --region us-east-1will transform to:- name: Describe instances
command: aws ec2 describe-instances --region us-east-1
environment:
AWS_ACCESS_KEY_ID: "{{ lookup('env','AWS_ACCESS_KEY') }}"
AWS_SECRET_ACCESS_KEY: "{{ lookup('env','AWS_SECRET_KEY') }}"NOTE: This only injects env.var. for the specific task - not the whole playbook!
So you have to amend this way every AWS CLI task.

I faced this same problem using my own docker-based configuration
and the change that cleared it up for me was to addclient_max_body_size 20M;at every level in the nginx.conf file for my container's nginx.However, my nginx.conf was quite a bit more elaborate than yours.
I don't understand how yours can work with only an http clause.Here is what my nginx.conf looks like:upstream myapp {
server unix:///var/run/myapp.sock;
}
client_max_body_size 20M;
server {
listen 80;
server_name mayapp.com;
# path for static files

I have a Rails/Postgres app hosted on AWS Elastic Beanstalk.

See alsohttps://stackoverflow.com/a/6927400/122441As an example, a medium sized website database might be 100 GB in size and expect to average 100 I/Os per second over the course of a month. This would translate to $10 per month in storage costs (100 GB x $0.10/month), and approximately $26 per month in request costs (~2.6 million seconds/month x 100 I/O per second * $0.10 per million I/O).

Current execution context is not aware of the python's environment preferences.All you have to do is to assignPYTHONPATHenvironment variable before you executeawsclicommand.Example:export PYTHONPATH=$PYTHONPATH:/home/ubuntu/.local/lib/python2.7/site-packages
# For example list files from your bucket
aws s3 ls s3://mybucket --recursiveIn order to set correct path forPYTHONPATHyou need to check where are the python packages are installed on your computer/server.
Above example is from my ubuntu 16.04 server were python2.7 is installed by compiling python's source code.Depending on how python is installed, you should search for one of the folderssite-packagsordist-packageswhich contains list of installed python packages.Also, on another server I've found that required package are on following location:export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/dist-packagesHere is the example what is located inside mysite-packagesfolder.view image

I'm having problems recently creating a new Amazon RDS database (mySQL) and associating it with an Amazon Elastic Beanstalk environment. I have done this painlessly in the past for other environments (simply by going to the environment's configuration tab -> data tier -> "create a new RDS database" -> entering details as needed -> pressing "Save").However, there is now a section at the end requiring me to"Select the subnets for RDS instances in your Availability Zone". I have to tick both of the two subnets detected (which are contained in the default VPC) because I'm required to have a subnet in at least two Availability Zones (despite having selected Single Availability Zone - if that's relevant).When I click "Apply" I get the error message:"DBSubnets: Invalid option value: '' (Namespace: 'aws:ec2:vpc', OptionName: 'DBSubnets'): Specify the VPC ID and make sure all subnets exist."Any ideas about what I've done wrong? I'm unsure where exactly I'm meant to specify the VPC ID, and why I even have to.Sorry if I've misunderstood something - I'm fairly new to this stuff. Thanks in advance for any help.

I think there is one way to get preassigned url of all items by creating an array of multiple getCommands, getCommand can handlemultiple commandsand then you can usetoArray()function of Aws\CommandInterface to convert it into an array. ThecreatePresignedRequest()function does not support for multiple requests either you have to called it repetitive or need to use angetObject()

$request = $client->createPresignedRequest($cmd, '+20 minutes');
$presignedUrl = (string) $request->getUri();

Error 405 stands for "MethodNotAllowed" where the specified method is not allowed against this. Since you have mentioned that Main Server successfully sends the messages to SQS (you have verified it via the console), I will provide a solution to implement a worker thread. This was taken fromthis repositoryin GitHub. Have a look at the worker.php file.$queue = new Queue(QUEUE_NAME, unserialize(AWS_CREDENTIALS));
// Continuously poll queue for new messages and process them.
while (true) {
$message = $queue->receive();
if ($message) {
try {
$message->process();
$queue->delete($message);
} catch (Exception $e) {
$queue->release($message);
echo $e->getMessage();

I'm trying to set up Laravel 4.2 queue using AWS SQS and an EB Worker environment. I'm pushing the job into the queue from another server and I want the worker environment to execute it. But so far it looks like the worker tries to execute it, but for some reason gets a 405 error in the access log...I'm trying to get a very simple test code... On the worker env. I pretty much clean Laravel installation just with queue config and stuff and this class:class TestQueue {
public function fire($job, $data)
{
File::append(storage_path().'/sqs_push.txt', $data['date']);
$job->delete();
}
}Now on the main server, from where I want to push, I have this:public function getTestQueue(){
$data = ['date' => date('Y-m-d H:i:s')];
$queue = \Queue::push('TestQueue', $data);
var_dump($queue);
}On the worker I have launched thephp artisan queue:listenWhen I run that method, it adds it to the SQS queue (I can see it in the SQS console) and the worker tries to execute it, but all I see is some 405 errors in the access logs...
Maybe im doing something wrong in my queue setup? Can anyone help me please?

Have your try adding a CNAME alias for your cloudfront domain ??After setting up the CNAME alias, you can set the cookies on the base domain, then you will be able to pass your cookie.Let's put more detail to it in case people want to know what would be the next step is, let's use the following example :-You are developing onmy.fancy.site.mydomain.comYour Cloudfront CNAME alias iscontent.mydomain.comMake sure you set your cloudfront signed cookies to.mydomain.comfrom your fancy appFrom this point on, you are able to pass the cookie for the CF.One quick way to test if your cookie is set appropriately, try to get your assets URL, and put the url in the browser directly. If the cookie set correctly, you will be able to access the file directly.If you are using javascript to get the cdn assets, make sure in your JS code, you need to pass withCredentials option, or it won't work. For example, if you are using jQuery, you will need something like the following :-$.ajax({
url: a_cross_domain_url,
xhrFields: {
withCredentials: true
}
});And if the request is successful, you should get a response header from CloudFront with "Access-Control-blah-blah".Hope it helps people if they search this answer.

I am trying to build an app where users upload content on their browsers to an S3 bucket through CloudFront. I have enabled CORS on the S3 bucket and ensured that the AllowedOrigin is set to *. I can successfully push content from a browser to the S3 bucket directly so I know that CORS on S3 is configured correctly. Now, I am trying to do the same with browser -> CloudFront -> S3. CloudFront always rejects the pre-flight OPTIONS method request with a 403 forbidden response.I have the following options enabled on CloudFront:Allowed HTTP Methods: GET, HEAD, OPTIONS, PUT, POST, PATCH, DELETEWhitelist Headers: Access-Control-Request-Headers,Access-Control-Request-Method, Origin OPTIONS requests are disabled
from the "Cached HTTP Methods"CloudFront apparently now supports CORS but has anyone got it working for an HTTP method OPTIONS request? I tried asking this on theAWS forumsbut no responses.

We am currently doing a scientific project that requires us to do some (relatively) heavy numerical simulations. The issue is that we are required to use a Windows-based program that only supports single threading.Initially, we were under the assumption that a memory-optimized instance would be more cost-effective. Subsequently, we found out that the program doesn't utilize anything more than around 2GB of memory.Looking at the table of compute-optimized instances on offer, does ECU refer to the overall computational performance? Or is it an indicator of performance for a single vCPU/core? Since the program doesn't run on multiple threads (and by extension multiple cores), this is an important question for us.

There is a diffrence,In Amazon EC2, Elastic Load Balancing provides a special Amazon EC2 source security group that you can use to ensure that a back-end Amazon EC2 instance receives traffic only from the ELB load balancers.Regarding your other question,
You cannot (as far as I know) direct ELB to VPC.
ELB can only be directed to Public subnet ELB and from there to Private subnet ELB.I suggest you read more here:Elastic Load Balancing

I have created CNAME using Route 53 for a ELB (2 VPC instances added with it). Verified CNAME withhttp://mxtoolbox.com. It looks fine. Alsonslookup -q= CNAME.MYDOMAINshows my CNAME and address fine.My problem is, CNAME.MYDOMAIN is not loading in web browser. Where as the same setup works for ELB (with EC2-Classic instances) and loading in web browser.Is there any different CNAME setup for ELB with VPC instance and ELB with EC2-Classic instance?

I've encountered an issue where notebooks wouldn't save on the nbserver on AWS EC2 instance I set up in a similar manner via different tutorial. It turns out I had to refresh andre-loginusing the password, because my browser would automatically log out have a certain period. Might help if you close and re-attempt to go the the nbserver and see if it asks you to re-login.Here's a few other things you can try:try to copy a problematic notebook into the server (scp) and try to open+save, as opposed to going thru repo pull to see if anything changescheck if the hanging "saving notebook" message appear for notebooks in certain directoriescheck the ipython console messages when you save a problematic notebook and see if anything there can help you pinpoint the issue

I'm running a remote IPython notebook server on an EC2 instance on AWS. The instance is running Ubuntu.
Followedthistutorial to set up, and everything seems to work - I can access the notebook via https with a password and run code.However, I can't seem to save changes to the notebook - It says "saving notebook" and then nothing happens (i.e, still written 'unsaved changes' on top).Any ideas would be greatly appreciated.Edit: It's not a permissions problem, since running in sudo doesn't help.
When creating a new notebook in the remote server, I am able to save. Problem only occurs for notebooks pulled from my git repository. Also, when opening a problematic notebook, and deleting all cells until it's absolutely empty, I can sometimes (!) save the empty notebook, and sometimes (!!) I still can't.

I put up my rails application on AWS elastic beanstalk through Amazon's eb tool.
On elastic beanstalk, I'm using its default load balancer, and am running ubuntu 64bit with ruby 2.0.I'm getting two major problems:1) the root route isn't working.In my config/routes.rb, I tried:root 'controller#actionroot :to => 'controller#action'root to: 'controller#action'and found none of them working. The server was giving me an error saying that:Invalid route name, already in use: 'root' (ArgumentError)I guessed that there was some kind of clash between Rail's default root=>public/index.html and my own routing in config/routes.rb? So I created public/index.html and the root url '/' now serves public/index.html. I want to figure out a way to make it work the 'Rails' way, with the root url routing to controller#action.2) Static assets are not being served.in my layouts/application.html.erb file, I have the Rails defaulttrue%>
true%>However, when I fire up the Rails app on elastic beanstalk on production environment, I get:http://myurl.com/javascripts/application.js404 (Not found)http://myurl.com/stylesheets/application.css404 (Not found)Interestingly, assets in public/images get served correctly.Does anyone know the solutions for these problems?Thank You in advance!========================= Edit ===========================I'm using Amazon 64bit Linux with Passenger Standalone

As statedhereyou should specify a subnet when creating auto-scaling group. And though it is not stated that you have to have default VPC for creating launch configuration, I would say that readingthis. Particularly this lines:If your AWS account comes with a default VPC and if you want to create your Auto Scaling group in default VPC, follow the instructions in ...So you just need to create auto-scaling group in the desired subnet and use your launch configuration for this group.

I've had exactly this issue! The problem is that theRemove instance when < 2000000criteria is firing when you only have one instance. If your instance goes above 2000000 and then back down below 2000000, EB will terminate it and launch another one. Disable the autoscaling action for that alarm and your problem will go away.With regards to your second issue - how long are you waiting for the newly built instance to become available? I have noticed that new instances will be added to the autoscaling group as soon as they are ready, but before EB has finished deploying your application. In your single-instance situation, that's especially bad since there are no valid servers for a few minutes.

I'm running into two distinct, but related, issues with a Rails app (Ruby 1.9.3) I have deployed on AWS' Elastic Beanstalk. I have the following autoscaling config applied. I believe it is the default.Environment type: Load balanced, auto scalingNumber instances: 1 - 4Scale based on Average network outAdd instance when > 6000000Remove instance when < 2000000Issue #1 - My app doesn't get very much traffic yet and only requires 1 EC2 instance (m1.medium). I get several "ElasticBeanstalk Default Scale Down alarm" emails from AWS each week. Most of the time, I check my app after receiving one, and it's fine; however, about once a month, I check my app after receiving the email and find the nginx 404 page. EB has terminated my EC2 instance - the only one running my app - and generated a new one. Why is it scaling down from 1 to 0? This has happened to me with consistency for the past 6 months. Has anyone else experienced this? Found a solution?Issue #2 - When the above situation happens, EB creates a new EC2 instance for me. But, I continue to get the nginx 404 page until I re-deploy - which is a manual task and seems to defeat the purpose ofautoscaling. Does EB require a re-deploy after autoscaling occurs? Shouldn't it automatically deploy the current/latest version of my app to the new EC2 instance(s)?Any help/advice is greatly appreciated!

you can not get Canonical IDs via SNS ,but you can get it via Google GCM REST Api youself.see this:GCM with PHP (Google Cloud Messaging)result will have Canonical IDs.
|
I was going through Google Cloud Messaging documentation and I came across this section:http://developer.android.com/google/gcm/adv.html#canonicalCanonical IDsIf later on you try to send a message using a different registration ID, GCM will process the request as usual, but it will include the canonical registration ID in the registration_id field of the response. Make sure to replace the registration ID stored in your server with this canonical ID, as eventually the ID you're using will stop working.How do we handle the Canonical Id update while using Amazon SNS Endpoint ANRs?I checked the Amazon API documentation forCreatePlatformEndpoint:http://docs.aws.amazon.com/sns/latest/api/API_CreatePlatformEndpoint.htmlandPublish:http://docs.aws.amazon.com/sns/latest/api/API_Publish.htmlPlease suggest. Thanks!

Had the exact same problem and it turned to be the permissions set to the files when copying the files over. I was using the PHP library provided by Amazon, and when calling the copy method the permissions needed to be set to "bucket-owner-full-control". That worked for me. You are probably copying your stuff in a different manner, but maybe this is the path to follow.I started to find the solution readinganother question.

I struggled for a bit with the same question and I think I finally got an answer:Create a new SNS topic.Create an AWS Lambda function that launches the deploy for you on whatever you want using the JavaScript AWS-SDK. So you can get the idea:var AWS = require('aws-sdk');
AWS.config.region = 'us-east-1'; // Opsworks only uses this one for Stacks in any region
var opsworks = new AWS.OpsWorks();
opsworks.describeStacks({}, function(err, data) {
console.log(data);
context.succeed(message);
});Assign the required policies to this lambda function to allow whatever you call from the AWS API.Set Github to send the notification to the SNS topic rather than calling Opsworks directly.

PrintWriter writer = new PrintWriter(FS);
writer.write(averageDelay.toString());
writer.close();

This might be a character encoding issue.I was running into a similar issue while transferring some text fields between a MySQL database and DynamoDB. Certain special characters likeéwere not valid UTF-8 characters. And even though they were replaced with the replacement character (�), for some reason this was throwing a fatal error. I ended up having to run a check on all the fields before they were put into the database and convert the encoding to ASCII (which was the type all the other strings were set to). Instead of the�replacing the unknown characters, a?was used so it wasn't a "good" fix, but it did prevent the script from crashing.This is my best guess though as all I have to go off of is the error being similar to the one I was getting. And seeing as this question is old, thought I would attempt to answer it in case anyone else comes across this like me.

I am at a lost on how to query my Amazon CloudSearch from a static HTML page. Although the documentation is good there are no examples beyond copying and pasting a URL in a browser.What I would like is an HTML page in S3, so no server side code allowed, to have a text field form that when the search button is clicked fires to my CloudSearch end point and returns the resultsCloudSearch responds with JSON, so will have to parse that and make a table of the results.So far I have been working with a saved JSON of the results locally and using Jquery to read the JSON file<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>JSON Sample</title>
</head>
<body>
<div id="placeholder"></div>
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script>
$.getJSON('search.json', function(data) {
var output="<ul>";
for (var i in data.hit) {
output+="<li>" + data.hit[i].id+ "</li>";
}
output+="</ul>";
document.getElementById("placeholder").innerHTML=output;
console.log(data);
});
</script>
</body>
</html>This gives me the ID for the record.But when I try and change the URL to the CloudSearch end point I get no data back. Having read and gone round in circles I believe it is because of CORS.However, Amazon's documentation just say to use an HTTP GET on the endpoint but how do I build that into my HTML page.Sorry for such a basic question

Most interestingly, the first above post actually exhibits a JVM crash during network related events.The cryptic nature of this bug leads me to believe that there is a bug related to thread creation and scheduling which is specific to our current version of Ubuntu with respect to the way java invokes some of its concurrency features, or some underlying library incompatibility that is highly idiosyncratic to our particular situation.My Question(s)My main question here is - what is the best method for debugging a JVM stack trace involving these "safepoints", and where can I get started learning about dealing with such errors ?

Amazon provides a means of notifying bucket events (as seenhere), but the only event currently supported is thes3:ReducedRedundancyLostObject.I am afraid the only ways you can do what you want, today, are by either polling (or crawling, like you said) or modifying the clients who upload files to your bucket(s) (if you are in control of their code) in order to notify your boxes whenever stuff is uploaded/changed.

This question already has answers here:Closed11 years ago.Possible Duplicate:Notification of new S3 objectsGet notified when user uploads to an S3 bucket?What's the most efficient way to detect changes in Amazon S3? A number of distributed boxes need to synchronize local files with S3. Each box needs to synchronize with a portion of an S3 bucket. Sometimes files get dropped into a bucket from an external source, and so the boxes won't know about it.I could write a script that continually crawls all files on S3 and notifies the appropriate box when there is a change, but that will be slow and expensive. (There will be millions of files). I thought about enabling logging on the bucket, but it takes a long time for logs to get written, and I would like to get notified of changes fairly quickly.Any other ideas?

Some information is missing - what is your disk configuration?

I have deployed mongodb 64 bit 2.x version on aws m1.large instance.I am trying to find best performance that mongo can give us on aws in-light ofhttp://www.snailinaturtleneck.com/blog/tag/mongodb/(andmongodb read/write performance and mongo hosting in the cloud)I have created one db with one collection i.e. user and inserted 100,000 records/json object (each json object size is 4KB) using random number as suffix to “user-“. Also, created index on user id.Further, I set db profiler to log slow query taking 20ms or more. I have executed java program with 10 threads. Each java class generates user id with random number and finds it in user collection in infinite loop. With such load I have observed latency in query/read up-to 60ms.I also observed that when I run less number of threads say 3 or 4 (having query load on user collection 5K per second to find users) then I see no latency or less then 2ms latency.I failed to understand why increasing load of finding user in collection is causing latency. I believe that mongo db can perform much more concurrent read then what I am trying and should not impact on performance as such.One possibility I assume that would be - mongo is having performance issues if there are large queries executed on single collection like in our case, I expect to have 10K to 20K queries per second on single collection.We would appreciate your thoughts / suggestion.

<ListName>Wishlist</ListName>
<TotalItems>132</TotalItems>
<TotalPages>14</TotalPages>
<ListItem>
<ListItemId>EPIE5559HKT391</ListItemId>
<DateAdded>2003-11-17</DateAdded>
<QuantityDesired>1</QuantityDesired>
<QuantityReceived>0</QuantityReceived>
<Item>
<ASIN>5557205521</ASIN>
<ItemAttributes>
<Title>Horton hears a who</Title>
</ItemAttributes>
</Item>
</ListItem>
...The rest of the XML is just either more list items like that, or information about the request at the top of the response.

-1I found the solution. The issue was only with chrome browser. S3 static endpoint was on http and springboot backend application was on https.I created a cloudfront distribution for my s3 static website and now since both are on https i am not getting the error.

I am calling my rest endpoint from aws s3 static website and getting below CORS errorAccess to fetch at 'http://[my-public-ip]:5225/user/1'
from origin 'http://[my-bucket].s3-website-us-east-1.amazonaws.com'
has been blocked by CORS policy: The request client is not a secure context
and the resource is in more-private address space `private`.I have below code in my springboot for allowing cors, also i tried various other combinations like allowedOrigins, allowedMethods but none of them working@Override
public void addCorsMappings( CorsRegistry registry ) {
registry.addMapping( "/**" );
}Also i tried adding cors setting in s3[

"Authorization"
],
"AllowedMethods": [
"GET",
"HEAD"
],
"AllowedOrigins": [
"*"
],
"ExposeHeaders": [

source_fileis alocal path, not a remote url. Thus you can do:Download your file from github usingnull_resourcewithlocal_execas shownhere.Use yourarchive_fileto archive the newly downloaded file from github.

I need to archive a directory from my gitlab repo using terraform in order to use the ZIP file in an aws lambda function.
when putting a url in the source attribute it errors:Error: error archiving file: could not archive missing file: https://*********/lambda.pymy Terraform code for archiving the file is:data "archive_file" "init" {
type = "zip"
output_path = "${path.module}/example.zip"
source_file = "https://*********/lambda.py"
}so obviously this is not the right way to do it, didn't find anything regarding this online, is there a proper way to do this using Terraform?

-1Cognito will automatically setup Cloudwatch for your User Pool activity. You just need to go to Cloudwatch > Select "Cognito" from the Services list.Try to refine the time filter or set the refresh interval to make Cloudwatch regularly fetch the newest metrics.Hope this answers.
|
Our team is implementing a Web Application (ReactJS) that utilizes Amazon Cognito service for user sign-up, log-in, log-out.
However, instead of using Cognito's hosted UIs, we created our own login page and used amazon-cognito-identity-js sdk to implement the authentication functionality.Now, I need to be able to monitor the user activity (for example, which users logged-in from which location). I understand that this can be done by using Cognito's Advanced Security feature.I have set the user pool's Advanced Security Setting to "Audit Only". However, there are still no Cognito-related metrics showing up in Cloudwatch.I also tried to follow the instructions described in below site but to no results.https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-settings-viewing-advanced-security-app.htmlDoes anyone have any idea as to what setting I may have missed out?
Any advice is highly appreciated.

-1WhateverACLvalue you're using in the signature needs to also be sent in the request headers, as'x-amz-acl': '**-**-**'.Note also that an S3PUTdoes not expectFormData-- it expects thebodyto containonlythe raw bytes of the object. This isn't the cause of the error, but once you correct the signature error, you'll need to change this, too, in order to get a valid, usable upload.

I struggled with the same problem for hours, and in the end it turned out to be the user info endpoint that was wrong. I was using the same one as you, but it should behttps://openidconnect.googleapis.com/v1/userinfo.I haven’t found any Google documentation saying what the value should be, but found this excellent blog post that contained a working example:https://cloudonaut.io/how-to-secure-your-devops-tools-with-alb-authentication/(the first example uses Cognito, but the second uses OIDC and Google directly).

I am trying to set Listener rules on an ALB. I want to add Google Oauth support to one of my servers.Here are the Google endpoints I am usingI see google auth page alright, but on the callback url I'm seeing 500 Internal Server Error.

Any help is most appreciated!After authentication, I'm not redirecting to my application, instead I've set ALP to show a text based simple response.

Absolute SSM noob here, currently we use SSM in our lambda function, and to use it we simple import the SSM class and instantiate an instance, the constructor does the env var injections.from aws_ssm import SSM
ssm = SSM()While this works as expected when running on AWS Lambda, but it doesn't work well in our local computer, typically our local accounts not setup with SSM.In order to bypass the SSM and load the vars from actual existing env vars, I will have to add a switch:if not os.environ.get('NO_SSM'):
from aws_ssm import SSM
ssm = SSM()And this seems like a hack to me (especially False False condition to make it right), I am just wondering if there is a proper way to do it for local development?Just thinking again, it would have been better to reverse the situation originally to only use SSM whenUSE_SSMenv is defined:if os.environ.get('USE_SSM'):
from aws_ssm import SSM
ssm = SSM()

Is there a local development mode for AWS SSM?

-1You need to give access to the entire account from Dev/AdminRole and then restrict access from roles in the base account.

I have quite a few users in an AWS Account - let's call it the Base account:IAM:

user2
user3

-1You can set authorization only for resources and methods. For example, we have the following API structure:/
/test
GET (1)
PUT
/test/new (2)
ANY
/example/{proxy+}
GET (3)1) For methodsite.com/testendpointin GET method if you try to use the same key in PUT method you cath error.2) For resourcesite.com/test/newendpointin all methods in /test/new, but if you try to GET on /test/new/new2 you cath the error.3) For resource(with proxy)site.com/example/{proxy+}endpointYou can auth to any example/* path.

I am trying to use AWS API Gateway to proxy requests to some REST endpoints I have running in docker containers. I set up my API Gateway method for integration type HTTP and checked 'Use HTTP Proxy integration', But this is not simply proxying my requests, it strippes out the path parameters, query string parameters and body, and makes me map them to something.Am I missing something, I don't want API gateway transforming my request I just want it to proxy it back to my internal REST endpoints.FYI I am using a swagger doc to generate the API Gateway structure (their UI is quite annoying)I read about {proxy+} endpoints which sound like what I want, but how do I define swagger docs about a certain endpoint action, or have granular apikey and authorizors on my endpoints?

I found this is the easiest way to do this is like this:let request = new AWS.DynamoDB({apiVersion: '2012-08-10'})
let params = {
TableName: 'YOUR_TABLE_NAME',
Key: {
'YOUR_KEY': { S: 'STRING_VALUE_TO_MATCH' }
}
}
let result = await request.getItem(params).promise().then((data) => {
return data.Item
})
// Now you can use result outside of the promise.
console.log(JSON.stringify(result))Make sure this is inside an async function and it should work for you. This isn't for a "scan" but the concept should be the same.

I am retrieving the data from dynamodb with aws's dbclient.scan function. I need to use the output data to retrieve data from another table. I am trying to assign the output of first db scan into variable that is outside of dbclient.scan. The problem is that I get empty variable eventhough I assigned data from dbclient.scan callback function. What should I do? Anyway, I haven't used promise and asynchronous concept. The following is the code that I wrote.var tmp = []
docClient.scan(params, (error, result) => {
if(error) { .......}
else{ var tmp1 = result.Items[0].data
tmp.push(tmp1)
}
});
console.log(tmp)//empty listWhat should I do?
Many thanks,
Sea

I have faced a similar problem and found a workaround insearch after APIwhich is not affected by that limit of 10k elements and thus can be useful in cases when you know you might have more than that and still want to render the total elements that are there. With the ability of relatively easy fetches without the hard restrictions on filters or search at the cost of a not-too-handy pagination, that can still be done somewhat easy.It is tricky to use, because:All indexes that you are searching in should be sorted by the unique field across all indexes"from" query parameter(of a page) should be set to 0send a "search after" value from last element on the the previous page of that fieldAnd you won't operate numbers in pages anymore, just the last elements of the pages, and the size of those pages that you want to see after that elementIt is not really an answer on how to jump to the last one but that is a solution to not changing the result window size, and or limiting resulting documents to 10k only

I am using search query to retrieve documents from elastic search which returns me nearly 50k documents. I have a UI which renders 100 documents per page and have a button to jump to last page.

-1You'd definitely benefit from Google Analytics custom task feature instead of custom HTML. More on this fromSimo Ahava.Also, Google Big Query is quite a popular destination for streaming hit data since it allows many 'on the fly computations such as sessionalization and there are many ready-to-use cases for BQ.
|
So the questions has more to do with what services should i be using to have the efficient performance.Context and goal:So what i trying to do exactly is use tag manager custom HTML so after each Universal Analytics tag (event or pageview) send to my own EC2 server a HTTP request with a similar payload to what is send to Google Analytics.What i think, planned and researched so far:At this moment i have two big options,UseKinesisAWS which seems like a great idea but the problem is that it only drops the information in one redshift table and i would like to have at least 4 o 5 so i can differentiate pageviews from events etc ... My solution to this would be to divide from the server side each request to a separated stream.The other option is to use Spark + Kafka. (Here is a detail explanation)I know at some point this means im making a parallel Google Analytics with everything that implies. I still need to decide what information (im refering to which parameters as for example the source and medium) i should send, how to format it correctly, and how to process it correctly.Questions and debate points:Which options is more efficient and easiest to set up?Send this information directly from the server of the page/app or send it from the user side making it do requests as i explained before.Does anyone did something like this in the past? Any personal recommendations?

My API has an OPTIONS method that is implemented through a Mock integration that is set to return the required CORS headers.The problem is that it returns500 Internal Server Errorwhen there is noContent-Typeset on the OPTIONS request. It is returning proper CORS headers with a200 SuccesswhenContent-Typeis set toapplication/json.How do I fix this as the OPTIONS request is sent by the browser and I don't think I'm allowed to setContent-Typeheader on it?

I installed NodeJS v8.1.2 on an Amazon Linux Distribution on aws.I have pm2 installed that is in-charge of restarting process in cases it fails.I catch uncaught exceptions in the process and log them so the process wont restart since I use socket.io and I don't want users to get disconnected on every single exception.about two month ago after updating nodejs to v7, nodejs would restart randomly with no reason what so ever, so I decided to compile nodejs from sources using nvm, and it resolved the issue.about a week ago I updated nodejs again to v8.1.2 and today the process restarted again with no reason at all, no exception... nothing on the servers stats where too high.. no reason what so ever.what do I do?any information regarding the issue would be greatly appreciatedupdatesI checked/var/log/messagesand I noticed a segmentation fault error at the time of the restart. do I have to create a core dump to investigate the issue further?can a segmentation fault of the nodejs process can be caused because of my code ?what do I do ? :)

I have a Cognito Federated Identity with Cognito User Pool as Auth provider. It all works and I can see that any new user added in user pool creates a new federated identity. But how do I know which Federated Identity is linked to which user in the User Pool in my code - say a Lambda? When I browse the Identity pool in AWS console, it just shows the User pool id in linked logins and not the User pool sub. Do I need to store a mapping between User Pool's sub to Identity pool's Identity id ?

-1Follow below steps to achieve this.1) buy your domain,example.com2) go to the Amazon S3 console and create a bucket namedexample.com3) add yourindex.htmlfile to it and provide read permissions4) enable static website hosting for the bucket, usingexample.comin the field5) go to the R53 routing part of the console and add aType Arecord set (IPV4)6) Select Yes for Alias and choose the endpoint from the drop down, it will be something likeexample.com..s3-website-us-west-2.amazonaws.com7) Hit 'Create'8) Go back to Hosted Zones and click theexample.comzone, on the right you will see 4 namespaces that look something like this:ns-XXXX.awsdns-54.org
ns-XXX.awsdns-15.com
ns-XXXX.awsdns-45.co.uk
ns-XXX.awsdns-27.net9) Copy these namespaces to a notepad or something10) The Amazon side is now configured, we just need to do the domain side, so in my case I went toiwantmyname.com11) Go to edit namespaces, and change them to the ones you copied from step 812) We're done! Just be patient as it does take some time to configure all of this. In my case it took about 15 minutes. You can ping the website or use nslookup to check up on the progress through your console:ping example.com
nslookup example.compinging is inferior to nslookup with S3 since Amazon blocks them

As per the design in Danilo's book, if you are using the aws-sdk javascript , you should define your objects like :var creds = new AWS.CognitoIdentityCredentials({
IdentityPoolId: //hard coded value for your system//
})
AWS.config.update({
region: 'us-east-1',
credentials: creds
});
var lambda = new AWS.Lambda();then once you receive your identityId and token , you should assign them to you creds as follow :creds.params['IdentityId'] = output.identityId;
creds.params['Logins'] = {};
creds.params['Logins']['cognito-identity.amazonaws.com'] = output.token;
creds.expired = true;where output is the response from your LambdAuthLogin Lambda function.

I am attempting to create an iOS app in Swift that uses the following authentication service using AWS Lambda -https://github.com/danilop/LambdAuthIt uses the AWS Mobile SDK for iOS to communicate with DynamoDB and Lambda -http://docs.aws.amazon.com/mobile/sdkforios/developerguide/Here is the sample code for the website that utilizes the token returned from the Lambda login function, I imagine the Swift code will be something similar -https://github.com/danilop/LambdAuth/blob/master/www/login.html#L69Here is the cloud function that generates the token for the user -https://github.com/danilop/LambdAuth/blob/master/LambdAuthLogin/index.js#L102I have created an identity pool in AWS Cognito (Federated Identities) and I have two roles, auth and unauth. My application appears to always being the unauth role (arn:aws:sts::123123123:assumed-role/_unauth_MOBILEHUB_123123123/CognitoIdentityCredentials). My users are being stored in a dynamodb table, with a salted password.The root of the problem is that I don't know the correct Swift code to write after I receive a login token from the service to transition my user into the authenticated role (use the auth arn). I want it to be using the auth role for every service call to AWS (dynamodb, lambda, etc). I'm hoping that someone can point me in the right direction - thank you.

Does Amazon not want us to use this price for some reason?http://docs.aws.amazon.com/AWSECommerceService/latest/DG/CHAP_ResponseGroupsList.html

I haven't found a way to see this easily in the UI. You can see the size of the individual snapshots by going to "AWS Backup" > "My Account" > "Backup Vaults". There, click on the vault you are interested in. Then click on the invididual recovery-points and their respective size is shown. Now add those values.On the command line using awscli and jq, you can sum them for the whole vault (replace MY_XXX by your specific values):aws backup --region MY_REGION list-recovery-points-by-backup-vault --backup-vault-name MY_BACKUP_VAULT_NAME --query 'RecoveryPoints[*].BackupSizeInBytes' --output json | jq add

How can I know the data size of my AWS backup vault?I can't find any instruction to view the data size of the vault in thisdocument.The reason I want to know the data size of the vault is that my AWS Backup costs me too much money. So I'd like to know how much data I've stored in the vault.

When you create a GCP Compute Engine instance (EC2 equivalent) you can declare that you want it to have a public IP address. This is an IP that you can use over the Internet to access your instance. GCP gives you two types of IP ... static (stable) or ephemeral. A static IP is yours until you explicitly release it. There is no charge for this as long as your compute engine is running. An ephemeral IP is one which is allocated to you dynamically and may change following a restart of your compute engine instance.GCP does not (currently ... things could always change) create a DNS entry that will resolve to your IP address over the Internet. It does create a DNS entry that can be usedinsideyour GCP VPC network to allow one compute engine to call another within the GCP environment.If you want to reach your Compute Engine via a DNS name it is your responsibility to create a DNS "A" record in your own DNS server. If you don't have a DNS server that you can use, then you can obtain a domain name for a few dollars and then create an instance of a GCP Cloud DNS Server and add an "A" record for your compute engine to that server.See also:Cloud DNSInternal DNS

On creating an EC2 instance on AWS, you can access it via IP address or a domain name provided by Amazon out of the box:Is there a similar thing available for Google Cloud out of the box? I'm on a network that blocks IP addresses, and wildcard DNS likexip.io, so I was curious to know about it. Also, is there a specific term this is called which I'm missing?

-1Ok, what i can suggest - you could actually do the 2nd index as "OrganizationId#processId" - the organization ID should be always known when searching - as you plan i guess to search of all items within an organization with specific process ID?This should work out for you (on the index, not the table)"Condition": {
"ForAllValues:StringLike": {
"dynamodb:LeadingKeys": "${aws:PrincipalTag/organizationId}#*"
},if i'm assuming the tag is with the org id

So, I am currently making a DynamoDB table with multiple indexes and trying to manage access control.I have a key (organizationId) that I do not want to use as my secondary indexes partition or sort key, because it would be pretty much pointless query-wise.DynamoDB tableTable name: ExecutionsPartition key: OrganizationId (String)DynamoDB Secondary IndexPrimary partition key: processId (String)Primary sort key: status (Number)Would the following IAM Policy condition effectively limit access on the secondary index based on the organizationId ?"Condition": {
"ForAllValues:StringEquals": {
"dynamodb:LeadingKeys": [
"anOrganizationId / Variable"
]
}
}

Didn't test it, as it involves setting up a test EMR server, but here's what should work:Step 5:ssh -i publickkey.pem -L 8080:127.0.0.1:7777 HOSTNAMEStep 6:Open jupyter notebook on browser using 127.0.0.1:8080

I am new to spark and AWS, I am trying to install Jupyter on my Spark cluster (EMR), i am not able to open Jupyter Notebook on my browser in the end.Context:I have firewall issues from the place i am working, i can't get access to the EMR clsuter's IP address i create on a day-to-day basis. I have a dedicated EC-2 instance (IP address for this instance is white listed) that i am using as a client to connect to the EMR cluster i create on a need basis.I have access to the IP address of the EC2 instance and the ports 22 and 8080.
Ido nothave access to the IP address of EMR cluster.Following are the steps that i am following:Open putty and connect to the EC2 instanceEstablish connection between my EC2 instance and EMR cluster

I hope this documentation will help you out, the steps are broken down and quite simple to follow:http://docs.aws.amazon.com/AmazonS3/latest/dev/walkthrough1.htmlYou can also use policy variables as well.It lets you specify placeholders in a policy. When the policy is evaluated, the policy variables are replaced with values that come from the request itself.
For example -${aws:username}:Further more you can also check out this Stackoverflow question (if seem relevant):Preventing a user from even knowing about other users (folders) on AWS S3

So I've been trying to define a policy to restrict a group of IAM users to a particular folder in an S3 bucket with no success. I've riffed off the policy outlined in this blog post.http://blogs.aws.amazon.com/security/post/Tx1P2T3LFXXCNB5/Writing-IAM-policies-Grant-access-to-user-specific-folders-in-an-Amazon-S3-buckeSpecifically I'm using the following:{
"Version":"2012-10-17",
"Statement": [
{
"Sid": "AllowUserToSeeBucketListInTheConsole",
"Action": ["s3:ListAllMyBuckets", "s3:GetBucketLocation"],
"Effect": "Allow",
"Resource": ["arn:aws:s3:::*"]
},
{
"Sid": "AllowRootAndHomeListingOfCompanyBucket",
"Action": ["s3:ListBucket"],
"Effect": "Allow",
"Resource": ["arn:aws:s3:::mybucket"],
"Condition":{"StringEquals":{"s3:delimiter":["/"]}}
},
{
"Sid": "AllowListingOfUserFolder",
"Action": ["s3:ListBucket"],
"Effect": "Allow",
"Resource": ["arn:aws:s3:::mybucket"],
"Condition":{"StringLike":{"s3:prefix":["myfolder"]}}
},
{
"Sid": "AllowAllS3ActionsInUserFolder",
"Effect": "Allow",
"Action": ["s3:*"],
"Resource": ["arn:aws:s3:::mybucket/myfolder/*"]
}
]
}Unfortunately this policy for some reason allows users to navigate not only into the specified folder but other folders present in the same bucket. How do I restrict users in such a way that they can only navigate into the specified folder?
