Hello team,

I want to

  1. Create AWS ec2 instance using one "with_items: ec2"

  2. After that I want to insert the IP address of those instances into /etc/ansible/hosts file. For that I am using local_action: lineinfile . But after that I want to use again with_items: “{{ec2.instances}}”

At that time it shows error, That Item is undefined.

Are we use those with_items twice in a playbook. Any example please suggest me.

Thank you in advance.

A variable does not disappear after being used in an item loop, so I suspect you aren’t referring to the variable correctly in the second task. Please post an example playbook and the full -vvvv output with the error.

  • name: Launch EC2 instance
    ec2:
    key_name: “{{keypair}}”
    group: default
    count: “{{count}}”
    instance_type: “{{instance_type}}”
    instance_tags: ‘{“Name”: “{{item.names}}”,“Type”:“{{tag_Type}}”,“Environment”:“{{tag_Environment}}”}’
    image: “{{image}}”
    wait: true
    region: “{{region}}”

aws_access_key: *****

register: ec2
with_items:

  • names: Ansible-1

  • names: Ansible-2

  • name: One Add the newly created EC2 instance(s) to the local host group (located inside the directory)
    local_action: lineinfile dest=“/etc/hosts” regexp={{ item.public_ip }} insertafter=“[launched]” line=“{{ item.public_ip }} ansible_ssh_private_key_file=~/.ssh/{{ keypair }}.pem”

with_items: “{{ec2.instances}}”

  • name: wait for ssh to come up
    wait_for:
    host: “{{ ansible_host }}”
    port: 22
    delay: 60
    timeout: 320
    state: started

with_items: “{{ec2.instances}}”

  • name: Print all ec2 variables
    debug: var=ec2

if you debug that you will get the real result name, it may be something like ec2.results.instances or something like that. can you post the debug output of ec2 variable?
