Passing variables between hosts

[Andrew Morgan]

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 

[Dick Visser]

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
