ansible add host to route53

Question

i am using ansible to provision servers on ec2, after creating the server i would like to create a host entry on route53 zone

---
- hosts: all
  connection: local

  tasks:
  - name: create ec2 instance
    action: 
      module: ec2 
      zone: "{{ zone }}"
      image: "{{ image }}"
      instance_type: "{{instance_type}}"
      region: "{{ region }}"
      vpc_subnet_id: "{{ subnet }}"
      group: "{{ security_group }}"
      key_name: "{{ sshkey }}"
      instance_tags: 
        Name: "{{inventory_hostname}}"
        Environment: "{{ Environment  }}"
        Date: "{{ Date}}"
        Noderole: "{{ NodeRole }}"
        ConfigurationGroup: "{{ ConfigurationGroup}}"
        Backups: "{{ Backups }}"

      count_tag:
        Name: "{{inventory_hostname}}"
      exact_count: 1


  - name: Ensure DNS entry exists
    action:
      module:  route53
      command: create
      overwrite: "yes"
      record: "{{ inventory_hostname }}.{{ server_zone }}" 
      type: A 
      zone: "{{ server_zone }}"
      value: "{{ item.private_ip }}"
    with_items: "ec2.instances"

the attributes, "inventory_hostname" , "server_zone" are defined in the inventory files for the hosts so they work when the EC2 instance is created.

however, when the playbook is run, it throws up the error "no attribute 'private_ip"

any ideas?

Answer 1

You are not registering ec2. How do you expect ec2.instances to contain private_ip?

  - name: create ec2 instance
    action: 
      module: ec2 
      zone: "{{ zone }}"
      .....
      exact_count: 1
    register: ec2

  - name: Ensure DNS entry exists
    action:
      module:  route53
      ....
      zone: "{{ server_zone }}"
      value: {{ item.private_ip }}
    with_items: ec2.instances
