  Environment:

Ubuntu 14.04

Summary:

The add_host Task only executes on a single host in a play's host list.

Steps To Reproduce:

playbook

---
- name: Environment group_vars
  hosts: all
  gather_facts: no
  tasks:

    - debug: var=inventory_hostname

    - name: Add to group
      add_host: name={{inventory_hostname}} groups={{env}}

- name: Groups
  hosts: all
  gather_facts: no
  tasks:
    - debug: var=group_names
    - debug: var=groups[env]
    - fail: msg="done"

inventory file try.yml

10.0.0.70
10.0.1.171

execution

ansible-playbook -i ansible/try ansible/try.yml -e 'env=acceptance'

Expected Results:

I expect the task which uses the add_host module, Add to group, to execute twice: once for each host in the play. At the end of the play, each host would be in the group acceptance.

Actual Results:
