title: loops over the registered variable to inspect the results in ansible
body: <p>I have an ansible-playbook that creates the multiple ec2 security groups using with_items and register the result.</p>
  
  <p>here is the var file for this playbook:</p>
  
  <pre><code>---
   ec2_security_groups:
     - sg_name: nat_sg
       sg_description: This sg is for nat instance
       sg_rules:
         - proto: tcp
           from_port: 22
           to_port: 22
           cidr_ip: 0.0.0.0/0
  
     - sg_name: web_sg
       sg_description: This sg is for web instance
       sg_rules:
         - proto: tcp
           from_port: 22
           to_port: 22
           cidr_ip: 0.0.0.0/0
         - proto: tcp
           from_port: 80
           to_port: 80
           cidr_ip: 0.0.0.0/0
  </code></pre>
  
  <p>and here is the playbook that creates the ec2 security groups:</p>
  
  <pre><code>---
  
  
  - name: EC2Group | Creating an EC2 Security Group inside the Mentioned VPC
     local_action:
       module: ec2_group
       name: "{{ item.sg_name }}"
       description: "{{ item.sg_description }}"
       region: "{{ vpc_region }}" # Change the AWS region here
       vpc_id: "{{ vpc.vpc_id }}" # vpc is the resgister name, you can also set it manually
       state: present
       rules: "{{ item.sg_rules }}"
     with_items: ec2_security_groups
     register: aws_sg
  </code></pre>
  
  <p>This works very well but the problem is that, I want to get the group id of each group that this playbook has created for the next task, I have tried it but it failed:</p>
  
  <pre><code>- name: Tag the security group with a name
    local_action:
     module: ec2_tag
     resource: "{{aws_sg.group_id}}"
     region: "{{ vpc_region }}"
     state: present
     tags:
       Name: "{{vpc_name }}-group"
    with_items: aws_sg.results
  </code></pre>
  
  <p>Can somebody point me that how I can get the group_id for each group from the register result. Thanks</p>
  
  <p>P.S: I can get the value of the group_id for individual sg group like:</p>
  
  <p>aws_sg.results[0].group_id and aws_sg.results[1].group_id etc</p>
