If you have a script with a name that is part of your public interface then you need to start versioning this script explicitly, and keeping old versions around for older clients.e.g. /assets/script.1.0.js, /assets/script.1.1.js etcThe key part is that you need to be keeping the old ones around, and the code doesn't change without the name changing explicitly. The Rails asset pipeline can't do this for you, since there's usually only the very latest version of the script kept current.As with all public interfaces, you will need to spend more time on managing this process than you would for an internal-only script. | I have a script 3rd party websites are using:/assets/script.js. For obvious reasons, I can't ask them to change the link every time I deploy to point to the latest fingerprinted version of the script. I got a few caching issues where users still see old versions of/script.js. Are there any ways to make the cache go away directly forscript.jsinstead ofscript-9dc5afea3571ba2a883a72b0da0bb623.js?More Information: Rails on Passenger + Nginx. Looking for ways to serve thescript.jsfile instead if the finger-printed file and invalidate the cache on every deployment.I thought about adding ETags based on the deployment git revision, but have no idea how to do this. Nginx has no built in ETags support. There are unsupported old third party modules that do this. I can useadd_header Etag="something"for this, but how do I add the git version there.Any other ideas and options?Thanks! | 3rd Party Script Caching in Rails 3.1 |
I've found 1 possible solution with the suggestion from a co-worker.I'm now passing URI as a query parameter in nginx. So my config is now this:location / {
try_files $uri $uri/ /index.html?uri=$uri
}Then in my router configuration in VueJS:const routes = [
{
path: '/',
component: Landing,
beforeEnter: (to, from, next) => {
const { uri } = to.query;
if (uri != null && uri != '/') {
next(false);
router.push(uri);
} else {
next();
}
}
}, ...This seems to do the trick, although looks a bit dodgy. | I'm trying to setup a vue-router on my nginx server. The issue I'm having is that my route doesn't work if I enter url directly to the browsermyapp.com/mypath.I've tried server configuration as described in thevue router docsas well as suggested similar configurations on stack overflow.

try_files $uri $uri/ /index.html;

Nginx is a web server and is concerned with web server stuff, not with how to run Python programs. uWSGI is an application server and knows how to speak WSGI with Python (and other languages now). Both Nginx and uWSGI speak the uWSGI protocol, which is an efficient protocol over UNIX sockets.Nginx deals with http requests from/responses to the outside world (possibly load balancing, caching, etc.). Your Flask application deals with WSGI requests/responses. uWSGI knows how to start your application (possibly with multiprocessing and/or threading) and bridge the gap between HTTP and WSGI.There are other HTTP servers besides Nginx, and other WSGI servers besides uWSGI, but they all use the same workflow: the HTTP server passes to the WSGI server, which manages your application process and passes back to the HTTP server.This setup is known as areverse proxy. It allows each tool to do what it's good at and not be concerned about the other parts of the process. There is nothing particularly inefficient about it, until you get to trulymassivescales. | So from the Python/Flask docs, they both recommend not running the Flask web server as the production web server which makes sense. My question is, am I then able to run my Flask application on top of an Nginx server? Why do all the guides on the internet recommend wrapping Flask around uWSGI, Tornado, or some other WSGI server? What does it mean for something to be WSGI? Isn't Flask WGSI compliant?I am particularly lost becausehere, the first response states:Apache and Nginx are both HTTP servers.They can serve static files like
(.jpg and .html files) or dynamic pages (like a Wordpress blog or forum written in a language like PHP or Python).Howeverthispost states:Nginx is a web server. It serves static files, however it cannot execute and host
Python application. uWSGI fills that gap.It just seems inefficient for my application to be handled by a server (ex: uWSGI) and then another server (ex: Nginx). | Why does running Flask with Nginx require a WSGI wrapper? |
Best way (IMHO) is using apache+mod_wsgi. Both uWSGI and Gunicorn are not windows-friendly (albeit uWSGI has cygwin support, so you can eventually try it [if you are brave enough]).Another approach would be installing a linux vm (virtualbox, vmware...) on the windows machine to host your application and proxy requests from local IIS to the virtual system. | I have a django project.

Basically connections are established to make requests using it. So for instance endpoint for given key may accept 5 connections per hour from given IP address. But it doesn't mean only 5 requests can be made but much more - if the connection is not closed after a request (from HTTP 1.1 it's by default kept alive).E.g. an endpoint accepts 5 connections and 10 requests from given IP address. If connection is established for every request only 5 requests overall can be made. If connection is kept alive single client may make all the requests. If there are 5 clients, every establishes a connection and keeps it alive there are 2 request approx. that can be made by each client - however one can make all the request if it's fast enough. | While I am configuring my nginx, I found two modules:ngx_http_limit_conn_moduleandngx_http_limit_req_moduleone is for limiting connection per defined key, and one for limiting request.My question is what is the relationship (and difference) between

Maybe I am too late.As a complement of your own answer there is a solution not having to add the nginx user to the node group.Create a directory only for the socket file, assign it to the node user and www-data (or whatever group the nginx is) group and set the group-id bit (SGID) on that directory.mkdir -p /var/lib/yourapp/socket
chown nodeuser:nginxgroup /var/lib/yourapp/socket

There's just a few problems:The socket file stays present on shutdown, so I have to delete it when bringing the server back up, otherwise I will get the EADDRINUSE error.The nginx server runs as the nginx user, and the node server runs as the node user.The socket file gets created by Express when the server starts up and umask sets the permissions on the socket file to 755.The setuidgid application sets the group to the default group of the user, both the node username in this case.The deployment scripts for the application and daemontools' run script execute before the node server instance gets launched, so there's no way to set the permissions on the file, as it has to get recreated during the launch process.If I chgrp and chmod g+w the socket file, everything works fine. Is there a way to set this up so that the node application's socket file gets generated with the correct permissions for nginx to be able to write to it without compromising the security independence of one application or the other? I would even be okay with adding nginx to the node user's group, if there was still a way to set the permissions on the socket file so that it would be group writable. | Node Express Unix Domain Socket Permissions |
Nginx adds its header just before the origin server, so you will have:cache-control: public, max-age=10
cache-control: public, max-age=60and the origin header will replace the nginx header.The solution? Use nginx v1.4.3 that has the module more_set_headers and more_clear_headers in order to replace or clear the headers from origin.You can download the module fromhere.Herehow to download nginx 1.4.3 and how to install it.Herehow to use the directives. | When you use the add_header directive in nginx, the header is added to the response coming from the origin server.Say the origin server returns cache-control public, max-age=60. But in the nginx reverse proxy location you set something like:add_header cache-control public, max-age=10What does this do exactly? There are 2 different scenarios I can think of:1) Nginx respects the cache-control header from the origin server and stores the content in its cache with an expiration of 60 secs. Then passes on the response with an overwritten header causing the client to store the resource in its cache with an expiration of 10s.or..2) Nginx overwrites the response headers first and then interprets them. It stores the resource with an expiration of 10 secs and passes the response to the client which also caches the it with an expiration of 10 secs. | Nginx add_header and cache control |

There are a couple ways to achieve this. What you are referring to is usually calledservice discoveryand comes in many forms. I'll describe two of them that I have used before.The first and simplest one (which works fine for single servers or only discovering containers locally on one server) is a local proxy which makes use of the Docker socket or API.https://github.com/jwilder/nginx-proxyis one of the popular ones and should work well for prototyping scalable services in Compose.Another way (which is more multi-host friendly but more complicated) would be registering services in a registry (such as etcd or Consul) and then dynamically writing out the configuration. To do this, you can use a registration system (such ashttps://github.com/gliderlabs/registrator) to register the containers and their ports. Then your proxy or application can consume a configuration file written out using a template system likehttps://github.com/kelseyhightower/confd. | I'm running Docker Compose (v2) and have a node service (website) and python based api deployed with nginx sitting in front of them.One thing I would like to do is be able to scale the services by adding more containers. If I know ahead of time how many containers I will have, I can hardcode the nginx upstream config with the references to the IPs of the containers which docker makes available. However, the problem is that I want the upstream nginx config to be dynamic e.g. if I add another Docker container, it simply adds appends the location of the container to the upstream list of IPs in the upstream block.My idea was to create a script which will automatically append the upstream servers using env variables when the containers change but I'm unsure where to start and can't find a good example. | Automatically append docker container to upstream config of nginx load balancer |
Basically, you do the same thing you did to get everything for your first application running minus the Nginx installation. So, however you got your Unicorn instance for your first application running, do it again for your next application.You can then just add another server block into your Nginx config with an upstream that points to that new Unicorn instance.One Nginx running for the entire machine will do fine, with one Unicorn running per application.Hope this helps some.Here is a sample of the additional server block you would need to add for Nginx to serve additional applications:upstream unicorn_app_x {
server unix:/path/to/unicorn/socket/or/http/url/here/unicorn.sock;
}
server {
listen 127.0.0.1:80;
server_name mysitehere.com aliasfor.mysitehere.com;

Nginx open source version supports thehashdirective that may work similarly (not exactly the same though) to the sticky session mechanism provided by commercial version:The generic hash method: the server to which a request is sent is
determined from a user-defined key which may be a text, variable, or
their combination. For example, the key may be a source IP and port,
or URI:upstream backend {
hash $request_uri consistent;
server backend1.example.com;
server backend2.example.com;
}https://www.nginx.com/resources/admin-guide/load-balancer/So how do you use 4 octets from IPv4 with the hash method? Let's find how to get the client IP from the Embedded Variables sectionhttp://nginx.org/en/docs/http/ngx_http_core_module.html#variables$remote_addr client addressSo the code looks like:upstream backend {
hash $remote_addr consistent;
server backend1.example.com;
server backend2.example.com;
}UPDATE:If take a look at the Stream module (TCP proxy), the very first example shows exact the same approach:upstream backend {
hash $remote_addr consistent;
server backend1.example.com:12345 weight=5;
server backend2.example.com:12345;
server unix:/tmp/backend3;
}
server {

In principle, the NGINX ingress controller is indeed scalable -- it pulls its entire configuration from the Kubernetes API server and is in itself basically stateless.In practice, this depends very much on how your ingress controller is set up. First of all, the ingress controller will not auto-scale by itself. If you have deployed it using aDeploymentcontroller, you can usehorizontal pod autoscalingas described in the documentation. If you have deployed it using aDaemonSet, the ingress controller will automatically scale up and down with your cluster (maybe even automatically, if you're using thecluster autoscaler).In both scenarios, you're going to need aServicedefinition (possibly of typeNodePortorLoadBalancer, to allow for external traffic) that matches all pods created by the deployment/daemon set to distribute traffic among them. | When the Ingress Nginx controller reach its full capacity does it auto scale?
Is Kubernetes Ingress even scalable? | Can kubernetes Ingress Nginx be autoscaled? |
I believe you do need to move the SSL termination to the ingress controller because I am having the same issue and I appear to be in a permanent redirect situation. The traffic comes into the NLB on 443 and is terminated and sends to the backend instances over port 80. The ingress sees the traffic on port 80 and redirects to https:// and thus begins the infinite loop. | I've tried the following to get HTTP to redirect to HTTPS.

The difference is that in the case of uWSGI there is no "real" load balancing. The first free process will always respond, so this approach is way better than having nginx load balacing between multiple instances (this is obviously true only for local instances). What you need to take in account is the "thundering herd problem". Its implications are exposed here:http://uwsgi-docs.readthedocs.org/en/latest/articles/SerializingAccept.html.Finally, all of the uWSGI features are multithread/multiprocess (and greenthreads) aware so the caching (for example) is shared by all processes. | I've noticed that you can start multiple processes within one uWSGI instance behind nginx:uwsgi --processes 4 --socket /tmp/uwsgi.sockOr you can start multiple uWSGI instances on different sockets and load balance between them using nginx:upstream my_servers {
server unix:///tmp.uwsgi1.sock;
server unix:///tmp.uwsgi2.sock;
#...
}What is the difference between these 2 strategies and is one preferred over the other?How does load balancing done by nginx (in the first case) differ from load balancing done by uWSGI (in the second case)?nginx can front servers on multiple hosts. Can uWSGI do this within a single instance? Do certain uWSGI features only work within a single uWSGI process (ie. shared memory/cache)? If so it might be difficult to scale from the first approach to the second one.... | Multiple server processes using nginx and uWSGI |

This exact situation took me forever to figure out, but OSS is like that I guess.

I can't speak for Flask, but I can for CherryPy. That looks like the "proper way"...mostly.

In my gunicorn settings, settingworkers=2solved this issue.When I was sending a request to the external URL, the external application would send a request back.

The way that SSEs are built is by the client opening a connection to the server, which is then left open until the server has some data to send. This is part of the SSE spec, and not a thing specific to ActionController::Live. It's effectively the same as long-polling, but with the connection not being closed after the first bit of data is returned, and with the mechanism built into the browser.As such, the only way it can be implemented is by having multiple open client connections to the webserver which sit there indefinitely. As to what resources are required to deal with them, I'm not sure, as I've not yet tried to benchmark this, but it'll need enough servers for Puma to keep open thousands of connections if you have that many users with a page open.The default limit for puma is 16 concurrent connections. Several blogs posts about setting up SSEs for Rails mention upping this to a larger value, but none that I've found suggest what this higher value should be. They do mention that the number of DB connections will need to be the same, as each Rails thread keeps one running. Sort of sounds like an expensive way to run things."Run a benchmark" is the only answer really.I can't comment as to reverse proxying as I've not tried it, but as SSEs are done over standard HTTP, I shouldn't think it'll need any special setup. | I'm experimenting with Rails 4ActionController::Liveand Server Sent Events. I'm using MRI 2.0.0 and Puma.For what I can see, each connected client keeps an active connection to the server. I was wondering if it is possible to leverage SSEs without keeping all response streams running.Puma manages multiple connections using threads, and I imagine there is a limit to the number of cuncurrent connections.What if I want to support a real-world scenario with thousands of clients registering to my Rails app for SSE events?Is there any example?Also, I usually run Rails app servers behind an nginx reverse proxy.

Found the solution to my issue by searching for Nginx used as a reverse proxy for any other application with basic_auth.Solution was the answer found here:https://serverfault.com/questions/511846/basic-auth-for-a-tomcat-app-jira-with-nginx-as-reverse-proxyThe line I was missing from my nginx configuration was:# Don't forward auth to Tomcat
proxy_set_header Authorization "";By default, it appears that after basic auth Nginx will additionally forward the auth headers to Jenkins and this is what was leading to my issue. Jenkins receives the forwarded auth headers and then thinks it needs to authorize itself too?!If we set our reverse proxy to not forward any authorization headers as shown above then everything works as it should. Nginx will prompt basic_auth and after successful auth we explicitly clear (reset?) the auth headers when forwarding to our reverse proxy. | Below is my nginx configuration file for Jenkins.

You have configured nginx as an HTTP reverse proxy, however rabbitmq is configured to use the AMQP protocol (see description of tcp_listeners athttps://www.rabbitmq.com/configure.html)In order for nginx to do anything meaningful you will need to reconfigure rabbitmq to use HTTP - for examplehttp://www.rabbitmq.com/web-stomp.html.Of course, this may have a ripple effect because any clients that are accessing rabbitmq via AMQP must be reconfigured/redesigned to use HTTP. | I am trying to setup rabbitmq it can be accessed externally (from non-localhost) through nginx.nginx-rabbitmq.conf:server {

Will likely be one of two reasons:You are using anti-virus software and it is MITM your traffic and so downgrading you to HTTP/1.1.

Scan your site usinghttps://www.ssllabs.com/ssltest/to check your TLS config and improve it.The third reason islack of ALPN support in your SSL/TLS library(i.e. You are using openssl 1.0.1 and need to be one 1.0.2 or later, for example) but you have already confirmed you have ALPN support so skipping that for this answer. | I setup my Nginx conf as perDigital Ocean paper,

Whendefaultis not specified in a map block, the default resulting value will be an empty string. So, in your case, whatever value$storecodeis set with in the first map block, it is replaced with an empty string in the second one.Since map variables are evaluated when they are used, you cannot set$storecodeas the default value in the second map block, because that will cause an infinite loop.So the solution is to introduce a temporary variable in the first map block and then use it as the default value in the second block:map $host $default_storecode {
default dom_nl;

Hopefully this helps with your question about the nginx config files. You can find the nginx configuration for your sites by runningcd ~/.config/valet/Nginxin your terminal. To get to the base nginx config for valet usecd /usr/local/etc/nginx/valet. You should then seevalet.conf, inside you can update the following lines to put the log files where you want them.access_log "/Users/[user_id]/.config/valet/Log/access.log";
error_log "/Users/[user_id]/.config/valet/Log/nginx-error.log";Make sure to runvalet restartafter you make changes to the valet.conf file. | I'm using laravel valet to serve sites in my local dev env, which is great.

Most likely you have another service listening on 8080, I think the omnibus install have some service hooking 8080 - just use 8081 instead.Edit:I just did a quick search and found that it's the unicorn server that is listening to 8080 with the original omnibus installer.Note:You will only need to change the external_url in gitlab.rb, no other config file should have to be edited for this.Edit#2:As @emeraldjava stated there is an option in the configuration file for using another unicorn port:#unicorn['port'] = '8080' | I'm currently in the process of trying to get Gitlab omnibus installed on my private Debian server, and it works perfectly on port 80, the problem is I also have an Apache server listening on port 80.

(I eventually tracked down a solution myself...)Install tomcat, then install the WAR version of TeamCity, which is in the download area above theJava EE Containertab.

Since Flask is handling the request, you could just add a little bit of information to the 404 error to help you understand what's passing through to the application and give you some real feedback about what effect your nginx configuration changes cause.from flask import request

It will serve up the content by proxying your app. This is useful because nginx has many capabilities (especially regarding security) that you then don't need to implement in your own app, including optional integration with https and selinux integration. Using nginx in front of your app also prevents you from needing to run java as root (typically only the root user can use port 80).

Yes, this behaviour is expected although docs also say:If proxy_pass is specified without a URI, the request URI is passed to the server in the same form as sent by a client when the original request is processed, or the full normalized request URI is passed when processing the changed URI:location /some/path/ {
proxy_pass http://127.0.0.1;
}Nginx engineers say the same:https://serverfault.com/questions/459369/disabling-url-decoding-in-nginx-proxyHowever if you append $request_uri to proxy_pass (and strip locale beforehand it may work assaidby Nginx engineer):set $modified_uri $request_uri;

It's not just a matter of performance, but a matter of compliance with the TLS specifications.I guess that most browsers can parse through these files and figure out what the correct order of the chain should be.Some browsers may be tolerant, but theTLS specification explicitly says that you MUST present the certificate chain in the right order:certificate_list
This is a sequence (chain) of certificates. The sender's
certificate MUST come first in the list. Each following
certificate MUST directly certify the one preceding it. Because
certificate validation requires that root keys be distributed
independently, the self-signed certificate that specifies the root
certificate authority MAY be omitted from the chain, under the
assumption that the remote end must already possess it in order to
validate it in any case.I suppose some servers could re-arrange the certificate chain in the right order when reading their configuration before sending their cert chain (in which case there might still be an performance issue), but this isn't always the case.I haven't tried to configure Nginx with a chain in the wrong order, but I know Apache Httpd will send the chain exactly as configured (so in the wrong order if it's configured in the wrong order). In doubt, I'd suggest to configure your server with the chain in the right order to make sure it's compliant with the TLS specification. | Closed.This question does not meetStack Overflow guidelines.

As Dag Nabbit stated, a Minecraft server does not talk http. You would typically do this via NAT. A proxy server needs to know the protocol, because as the name suggests, it acts on behalf of the the client. Nginx knows various protocols, not just http, but Minecraft is not one of them. You can however write a proxy module for this protocol and use the existing nginx infrastructure. Since I'm not familiar with the protocol, I can't comment on the fact that this would have any advantages over NAT. | I'm trying to run two Minecraft servers on the same machine on two different ports.

The best way is to use nginx server to serve you static file and let you node.js server handle the dynamic content.It is usually the most optimized solution to reduce the amount of requests on your node.js server that is slower to server static files than nginx for example :The configuration to achieve that is very easy if you already set a reverse proxy for you nodejs app.nd nginx configuration could beroot /home/myapp;
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html;
server_name _;
location /public/ {
alias /home/myapp/public/;
}
location / {
proxy_pass http://IPADRESSOFNODEJSSERVER:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
#try_files $uri $uri/ =404;
}Every request with /public/ at the first part of the url will be handled by nginx and every other request will be proxied to you nodejs app at yourIPADRESSOFNODEJSSERVER:NODEJSPORTusually theIPADRESSOFNODEJSSERVERis the localhostThe doc section of express tell thathttp://expressjs.com/en/advanced/best-practice-performance.html#proxyAn even better option is to use a reverse proxy to serve static files;
see Use a reverse proxy for more information.Moreover nginx will let you easily definecaching rulesso for static assets that doesn't change it can speed up your app also with one line.location /public/ {

Actually, I serve my assets in the node app, usingexpress.staticmiddleware.I read and read again that nginx is extremely efficient to serve static files.The question is, what is the best ?

Unicorn was not designed to handle "slow clients". You can read more about this in thePHILOSOPHYhelp file:Most benchmarks we’ve seen don’t tell you this, and unicorn doesn’t care about slow clients… but you should.A “slow client” can be any client outside of your datacenter. Network traffic within a local network is always faster than traffic that crosses outside of it. The laws of physics do not allow otherwise.Persistent connections were introduced in HTTP/1.1 reduce latency from connection establishment and TCP slow start. They also waste server resources when clients are idle.Persistent connections mean one of the unicorn worker processes (depending on your application, it can be very memory hungry) would spend a significant amount of its time idle keeping the connection alive and not doing anything else. Being single-threaded and using blocking I/O, a worker cannot serve other clients while keeping a connection alive. Thus unicorn does not implement persistent connections.If your application responses are larger than the socket buffer or if you’re handling large requests (uploads), worker processes will also be bottlenecked by the speed of the client connection. You should not allow unicorn to serve clients outside of your local network. | I'm a bit confused about this architecture. On one of the projects I'm working on, Unicorn was chosen as a Rails server. And it is put behind Nginx web server. As I understand Unicorn is fully functional web server and we don't plan to host any other Rails applications on the same server instance.So my question would be: what are the benefits of having additional layer in chain:client -> nginx -> unicorn -> unicorn worker | Is it necessary to put Unicorn behind Nginx ( or Apache) |
Big idea: To gain full control of your nginx configurations, you need to override the default settings in the.platform/nginx/nginx.conffile in your project directory.The problem: When I ssh'd into my EB instance, I found that in the file/etc/nginx/nginx.confstill includes the default settinggzip off. For some reason my extension of this file did not overwrite this setting. I suppose it's because in Amazon Linux 2, theproxy configurations should be under.platform/nginxdirectory.Solution: I usedsshto obtain a copy ofnginx.conf, added it to my project directory.platform/nginx, commented out the original settings for gzip, and added the new gzip settings.

First, mTLS and TLS/SSL termination are not exactly the same thing. mTLS ismutual authentication🤝 meaning the client authenticates the server and the server authenticates the client.Typically the SSL termination takes care of the server authenticating the client but it takes client support for the server to be able to authenticate the client.Also, theCertificate Authorityand what I believe you are referring to ascertificate managerare 2 different things.For Kubernetes, you can set upTLS/SSL termination on an Ingressusing aningress controller like Nginx. You cantotally use a self-signed certificate with your own Certificate Authority with this. The only thing is that your requests will not be verified but your client/browser unless the CA (Certificate Authority) is added as a trusted entity.Now with respect to mTLS you don't necessarily care if you use exactly the same CA, Cert, and Key to authenticate both ways. However, you would have to force your ingress to authenticate the client and with the Nginx ingress controller you can do it with these annotations:nginx.ingress.kubernetes.io/auth-tls-verify-client: "on"
nginx.ingress.kubernetes.io/auth-tls-secret: "default/mycerts"You would create the above secret in K8s with something like this:kubectl create secret generic mycerts --from-file=tls.crt=server.crt --from-file=tls.key=server.key --from-file=ca.crt=ca.crtSome more details in thisblog.Note: Service meshes likeIstio,Linkerd, andConsulsupport mTLS out the box between your services.✌️ | I have a Kubernetes cluster (AKS) that is hosting a REST echo service. The service runs fine via HTTP. I am using NGINX ingress to route traffic. I now want to set up this service via HTTPS and with mTLS, so forcing the client to specify a certificate to be able to communicate with the echo service. This is a POC, so I am using a self-signed cert.What Kubernetes components do I need to set up to be able to pull this off? I read NGINX documentation but wasn't able to understand if I need to create a Certificate Authority/Cert-manager in the Kubernetes cluster and use that to configure an ingress service to perform the mTLS step. I am OK with terminating the SSL at ingress (after mTLS has been performed) and allow an unsecured channel from ingress to the echo-service.I am hoping someone with experience with this kind of setup can provide some guidance.Thanks! | mTLS setup using self-signed cert in Kubernetes and NGINX |
It fails because you need to use the FQDN to Resolve the name.Using just the hostname will usually work because in kubernetes the resolv.conf is configured with search domains so that you don't usually need to provide a service's FQDN.However, specifying the FQDN is necessary when you tell nginx to use a custom name server because it does not get the benefit of these domain search specs.In nginx.conf added at the server level:resolver kube-dns.kube-system.svc.cluster.local valid=10s;Then used a FQDN in proxy_pass:proxy_pass http://SERVICE-NAME.YOUR-NAMESPACE.svc.cluster.local:8080; | This question already has answers here:DNS does not resolve with NGINX in Kubernetes(3 answers)Closed5 years ago.So, I would like to havenginxresolve hostnames for backends at request time.

Sure you can. Take a look at thenginx.conf example on tornado's homepage.The relevant bits in your case would be:http {
# Enumerate all the Tornado servers here
upstream frontends {
server 127.0.0.1:8000;
server 127.0.0.1:8001;
server 127.0.0.1:8002;
server 127.0.0.1:8003;
}
...
server {
...
# for your "static" website
location ^~ /static/ {
root /var/www;
if ($query_string) {
expires max;
}
}
# for your tornado's app
location / {
proxy_pass_header Server;
proxy_set_header Host $http_host;
proxy_redirect false;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_pass http://frontends;
}
...
}
...

The webserver needs a Unix domain socket to connect to the FastCGI application, but the socket can't be created. Most likely the directory you want it to be in doesn't exist (because they are automatically created when you do abind). | So I am following this guide:http://technotes.1000lines.net/?p=23and I am going through the steps. I have a VPN (slicehost.com) with Debian Etch, serving a website (static so far) with nginx. I used wget to download FastCGI and I did the usual make make install routine.So I guess since FastCGI can't normally run CGI scripts you have to use some type of perl wrapper to interpret the perl.Now I run this scripthttp://technotes.1000lines.net/fastcgi-wrapper.pland I run into the exact same problem that a person ran into on the page that the script was submitted:http://www.ruby-forum.com/topic/145858(I'm not a ruby person and there is nothing ruby oriented in there)I keep getting a# bind/listen: No such file or directoryAnd I have no idea how to proceed. I would appreciate any help and I can give any more details that anyone would need. | How can I run Perl scripts using FastCGI on Nginx? |
PythonAnywhere developer here: yes, that's right -- we do have nginx and uWSGI installed. When you create a website on the "Web" page on our site, what happens under the hood is (simplifying a bit) that we generate the appropriate nginx/uWSGI configuration files for you and start everything up so that you only need to work on the Django code.The reason that those tools (or similar ones like Apache and mod_wsgi) are necessary is that Django's built-in webserver is not designed for production use. You can run its "manage.py runserver" command to make it serve up pages on your own machine, but the system it uses for that is not designed for security or efficiency -- it just provides an easy way for you to get something running for debugging purposes. The same is true for the built-in webservers for the other Python web frameworks like Flask and web2py.nginx is designed to be fast, efficient, and secure, so it's a better choice to handle incoming web requests when your website is on the public Internet and thus subject to large amounts of traffic (if you're lucky and your site takes off) and also to abuse from hackers. That's not to say that it automatically makes your site fast and secure, of course, but at least it means that you're starting with the right system. It's also much better at serving static files (like your CSS, JavaScript, images, and so on) than Django is, because that's what it was built for.uWSGI is designed to receive incoming web requests and rapidly and efficiently delegate processing them to multiple worker processes, then collate the responses and send them back to nginx.Of course, all of that could in theory be built into Django instead -- but it would be a lot of work for the Django team to do that, and it would be a waste of time for them to re-invent the wheel rather than focusing on the areas where Django provides its real benefits, of making it easy to quickly develop complex websites. | I have experience in hosting simple Django projects in Pythonanywhere platform(I did't have to install nginx and uWSGI).Many people use nginx+Uwsgi with Django, why would that required ?I hope nginx is a web server, load balancer, mail proxy and HTTP cache. Uwsgi is a webs server gateway interface.Does all those things are being included default in Heroku / Pythonanywhere platforms ? | Django, why would I need nginx and uWSGI during hosting? |
Well actually you are right thehttpis the problem but not exactly that one in your code block. Lets explain it a bit:In yournginx.conffile you have something similar to this:http {
...
...
...
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}So everything you write in your conf files are inside thishttpblock/scope. Butrdpis nothttpis a different protocol.The only workaround I know for nginx to handle this is to work ontcplevel.So inside in yournginx.confand outside thehttpblock you have to declare thestreamblock like this:stream {
# ...
server {
listen 80;
proxy_pass 192.168.0.100:3389;
}
}With the above configuration just proxying your backend on tcp layer with a cost of course. As you may notice its missing theserver_nameattribute you can't use it in thestreamscope, plus you lose all the logging functionality that comes on thehttplevel.For more info on this topic check thedocs | I'm using the below config in nginx to proxy RDP connection:server {
listen 80;
server_name domain.com;
location / {
proxy_pass http://192.168.0.100:3389;
}
}but the connection doesn't go through. My guess is that the problem ishttpinproxy_pass. Googling "Nginx RDP" didn't yield much.Anyone knows if it's possible and if yes how? | How to proxy RDP via Nginx |
After having some discussions in this post and on twitter it looks like there is no easy way to achieve what I want via Webpack. The files are only served as static files at runtime and it is not possible to exclude a file at build time and include it at runtime.So I decided to go with the solution/workaround I had in mind: changing the static files when starting up the docker container.I create my docker image by doingnpm run build:prod
docker build -t angularapp .I am using the official nginx docker image as my base image and the Dockerfile looks likeFROM nginx:1.11.1
COPY dist /usr/share/nginx/html
COPY run.sh /run.sh
CMD ["bash", "/run.sh"]Therun.shis used to modify the config file viasedand to start nginx afterwards:#!/bin/sh
/bin/sed -i "s|http://localhost:8080|${BASE_URL}|" /usr/share/nginx/html/api.config.chunk.js
nginx -g 'daemon off;'This allows me to configure theBASE_URLvia environment variabel in mydocker-compose.ymlfile (simplified):version: '2'
services:
api:
image: restapi
frontend:
image: angularapp
environment:
BASE_URL: https://api.test.example.comWith this solution/workaround I can deploy the docker image created by my jenkins job for a specific version deploy in all my environments (development, staging, production) by configuring the REST API endpoint used via environment variable when starting the docker container. | We want to deploy ourAngular 2app usingDocker imagesin different environments (staging/test, production, ...)When developing locally we are connecting to the backend REST API viahttp://localhost:8080but when we deploy in the different environments we want to use thesame Docker imageand connect to adifferent REST API endpoint.What would be the preferred way toinjectthisconfigurationinto theDocker container at runtime?Is there a way to do this viaenvironment variables?Can we do this via aplain text filecontaining something like{

Basically I have a single server with single IP address, but I want to host two different web application within the server with different domain name. So, basically, for each domain name, I want it to redirect to different port number. I tried below and got an error[root@mysvr nginx]# nginx -t -c /etc/nginx/nginx.conf
nginx: [emerg] "proxy_pass" directive is not allowed here in /etc/nginx/nginx.conf:41
nginx: configuration file /etc/nginx/nginx.conf test failedFollowing is the Nginx setting. Line 41 is where the proxy_pass is.server {
listen 80;
server_name server1.com www.server1.com;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:1003;
}
server {
listen 80;

proxy_set_header Host $host;

The original example cannot be used directly, because the main configuration is at/etc/nginx/nginx.conf./etc/nginx/nginx.confhashttpdirectives, which includes thesites-enabled/*directives. The only changes to be made on/etc/nginx/nginx.confare:work_processes 4;
worker_connections 1024;Also, removetext/htmlfrom it because it's already gzipped by default.The end result of yournginx.confin your app should have nohttpdirectives, justupstreamandserver. | I'm using nginx 1.4.1. After copyingunicorn's example ofnginx.conf, I found out the settings must be moved to different directives. I still couldn't manage to place the following settings in thenginx.conffile:worker_processes,user,pidandeventsblock. When I place them as it is now, the log showsdirective is not allowed here. What should I fix?worker_processes 1;
user deployer sudo; # for systems with a "nogroup"
pid /run/nginx.pid;
events {
