Passing variables between hosts

Hello all,

I have a playbook that is 99% complete but fails on the last step.My inventory file and playbook are below. I only added the last parts

`

[dev]
dev_jenkins ansible_ssh_host=44.244.444.44 ansible_python_interpreter=/usr/bin/python27
will have multiple servers

[dev:vars]
ansible_ssh_user=atest
ansible_ssh_private_key_file=/Users/confluence/Desktop/atest
ansible_become_user=root
ansible_become_method=sudo
ansible_become_password=changeme
ansible_ssh_pass= changeme

[test]

[test:vars]
ansible_ssh_user=atest
ansible_ssh_private_key_file=/Users/confluence/Desktop/atest
ansible_become_user=root
ansible_become_method=sudo
ansible_become_password= changeme
ansible_ssh_pass= changeme

`

1)takes image of live server
2)launches the server
3)verify login
4)kill the server

The issue I am having is with killing the server - name: Terminate instances that were previously launched

  • hosts: all

  • name: Launch instance
    ec2:
    key_name: ansible
    group: “{{ group }}”
    instance_type: m1.small
    image: “{{ image }}”
    wait: true
    region: “{{ region }}”
    vpc_subnet_id: “{{ subnet}}”
    assign_public_ip: yes
    register: ec2

  • name: Add new instance to host group
    add_host:
    hostname: “{{ item.public_ip }}”
    groupname: test
    loop: “{{ ec2.instances }}”

  • name: Waiting for SSH to come up
    delegate_to: “{{ item.public_ip }}”
    wait_for_connection:
    delay: 60
    timeout: 320
    loop: “{{ ec2.instances }}”

  • hosts: test. ##blank in the inventory file, but new instance added to it so i can connect to the new instance with password and key
    become: True
    gather_facts: True

tasks:

  • name: Testing out the servers
    shell: “. /etc/profile; echo $DEV_ENV”
    args:
    executable: /bin/bash
    register: ENTRY

  • name: Output for test server
    debug: msg=“{{ ENTRY.stdout }}”

  • name: getting instance id again
    shell: “wget -q -O - http://169.254.169.254/latest/meta-data/instance-id”
    register: instanceterminate

  • name: Terminate instances that were previously launched
    ec2:
    state: ‘absent’
    instance_ids: “{{ instanceterminate.stdout }}”
    region: us-east-1

when: ENTRY.rc == 0 or ENTRY.rc >= 2

Problem:

In my inventory file, I have unique parameters per host like ansible_python_interpreter=/usr/bin/python27 , maybe different for each server. So when I add the newly spun up instance from the freshly taken ami I add it to a group called test which is blank in my inventory file(it has the key and password needed to login into the machine.) I do not know of a way to specify the ansible_python_interpreter that was used to be used again in this last step and I cannot specify it because it will change from server to server, and so commands to terminate the instance gives error.

changed=false msg: boto required for this module

Is there a way I can make this work?

Thank you

You seem to be trying to terminate an instance from that very instance?

That doesn’t sound like it would work.
You should use another host.

Thank Mr.Visser, using delegate_to worked

  • name: Terminate instances that were previously launched
    ec2:
    state: ‘absent’
    instance_ids: “{{ instanceterminate.stdout }}”
    region: us-east-1
    delegate_to: dev_java

when: ENTRY.rc == 0 or ENTRY.rc >= 2
