Creating dynamic hosts using ec2 module

Hi,

I am new with using the dynamic hosts option. I am creating ec2 instances and creating a dynamic host group so I could run several different roles on them after the instances are created.

My issue is that after the instances are created my other roles are being ran only on the first host in the inventory.

site.yml

  • name: Spin up EC2 servers
    hosts: ec2_instances
    connection: local
    gather_facts: true
    roles:

  • ec2
    tags:

  • ec2

  • hosts: dynamic_hosts
    gather_facts: false
    tasks:

  • ping:

  • debug: var=hostvars[inventory_hostname]

  • debug: msg=dynamic_hosts
    roles:

  • ping
    tags:

  • ec2

Tasks file:

  • name: Launch Instance
    ec2:
    group_id: “{{ hostvars[inventory_hostname].group_id }}”
    count: 1
    instance_type: ‘t2.nano’
    image: ‘{{ hostvars[inventory_hostname].image }}’
    wait: true
    region: ‘region’
    keypair: keypair
    instance_tags: “{{ hostvars[inventory_hostname].tags }}”
    profile: profile_name
    register: ec2

  • name: Add hosts group temporary inventory group
    add_host:
    name: “{{ item.public_ip }}”
    groups: dynamic_hosts
    ansible_ssh_host: “{{ item.public_ip }}”
    ansible_ssh_private_key_file: file.pem
    ansible_ssh_user: user
    ec2_instance_ids: “{{ ec2.instance_ids }}”
    with_items: ec2.instances

inventory file
[ec2_instances]
ec2test1 image=“image_id” tags=“{ ‘env’: ‘test’, ‘Name’: ‘test1’ }” group_id=‘group’
ec2test2 image=“image_id” tags=“{ ‘env’: ‘test’, ‘Name’: ‘test2’ }” group_id=‘group’

I run the playbook like this:
ansible-playbook --tags=ec2 -i inventory site.yml

The outcome is both ec2test1\2 instances are created but the ping role is being run only on the first instance in the inventory file(ec2test1).
It seems that the dynamic_hosts group that I am creating will not assign more than 1 object there.

Please assist.
