Working with AMIs Using Ansible

In our solution, we'll complete the required steps and add a task for collecting facts from EC2 metadata, which will help us collect the instance ID of node1.

Edit the playbook such that it resembles the following:

- hosts: node1
  become: yes
  tasks:
    - name: Update packages
      yum:
        name: "*"
        state: latest
    - name: Update image.txt
      lineinfile:
        path: /home/ansible/image.txt
        line: "Image updated {{ ansible_date_time.date }}"
    - name: Gather facts
      ec2_metadata_facts:

We will be using the facts we collected in the first play to satisfy the objectives for this task.

Edit the playbook such that it resembles the following:

- hosts: localhost
  tasks:
    - name: Stop node1
      local_action: ec2
      args:
        region: us-east-1
        state: stopped
        instance_id: "{{ hostvars['node1'].ansible_ec2_instance_id }}"
        wait: yes
    - name: Create AMI
      local_action: ec2_ami
      args:
        state: present
        instance_id: "{{ hostvars['node1'].ansible_ec2_instance_id }}"
        name: UpdatedImage
      register: ami_output
    - name: Write AMI info to file
      lineinfile:
        create: yes
        path: /home/ansible/ami.txt
        line: "{{ ami_output.image_id }}"

• Change some environment variables:
  • source keys.sh
• Run the playbook:
  • ansible-playbook /home/ansible/updateAMI.yml
• Log into the AWS Console and confirm the new EC2 instance:
  • Search for "EC2" in the AWS console search and select the EC2 dashboard.
• Confirm the AMI was updated:
  • Select AMIs from the menu on the left.
