title: msg: No handler was ready to authenticate. 1 handlers were checked. ['HmacAuthV4Handler'] Check your credentials
body: <p>So I am trying to run ansible on my ec2 instances on aws, for the first time on a fresh instance, but every time I try to run a play I can't get around this error message:</p>
  
  <pre><code>PLAY [localhost]
  **************************************************************
  
  TASK: [make one instance]
  ***************************************************** 
  failed: [localhost] =&gt; {"failed": true} msg: No handler was ready to
  authenticate. 1 handlers were checked. ['HmacAuthV4Handler'] Check
  your credentials
  
  FATAL: all hosts have already failed -- aborting
  
  PLAY RECAP
  ********************************************************************
     to retry, use: --limit @/home/ubuntu/ans_test.retry
  
  localhost                  : ok=0    changed=0    unreachable=0   
  failed=1
  </code></pre>
  
  <p>I think there may be something wrong with the permissions in my IAM user and group.  I have given my IAM user and group ReadOnlyAccess, AdministratorAccess and PowerUserAccess. I have an access id and secret access key that I am setting as environmental variable with the commands:</p>
  
  <pre><code>   export AWS_ACCESS_KEY_ID='AK123'
     export AWS_SECRET_ACCESS_KEY='abc123'
  </code></pre>
  
  <p>With 'AK123'and 'abc123' replaced with my actual id and key values.  What else do I need to do in order to get the ansible ec2 task working?</p>
  
  <p>UPDATE:<br>
  I fixed the problem, I guess I didn't really have a solid understanding of what environmental variables are. I fixed it by just setting my aws_access_key and aws_secret_key inside of my ec2 task, below is my working playbook</p>
  
  <pre><code>- hosts: localhost  
    connection: local  
    gather_facts: False  
  
    tasks:  
      #this task creates 5 ec2 instances that are all named demo and are copies of the image specified  
      - name: Provision a set of instances  
        ec2:  
           aws_access_key: .....  
           aws_secret_key: ....  
           key_name: .....  
           group: .....  
           instance_type: t2.micro  
           image: ......  
           region: us-east-1  
           ec2_url: .......  
           wait: true  
           exact_count: 5  
           count_tag:  
              Name: Demo  
           instance_tags:  
              Name: Demo  
        register: ec2  
  </code></pre>
  
  <p>I guess now I need to start using ansible vault to just hold my key and ID.</p>
