Hi!
I am maintaining a set of servers which host some LXD containers on them.
The playbooks to install them go like this: First playbook connects to the
LXD host, installs apps and services including the containers that are
configured for it. A second playbook connects to this host, loops through
its container configuration and adds them to an in-memory inventory group.
These containers are then installed in a second play in this playbook,
using the in-memory inventory group created just before.
This is working beautifully when used via ansible-playbook in push mode.
But with ansible-pull, the add_host group gets defined, but cannot be used
as inventory group later.
See this stripped down demonstration code:
*Playbook (debug.yml):*
---
- name: add container hosts to in-memory inventory
hosts: "{{ target_hosts }}"
remote_user: "{{ user | default('comdok') }}"
tasks:
- debug:
var: groups['containers']
- name: add hosts
add_host:
name: "{{ item.name }}"
ansible_host: "{{ item.ip4 }}"
group: containers
loop: "{{ lxd_containers }}"
no_log: true
- debug:
var: groups['containers']
- name: install LXC containers
hosts:
- containers
remote_user: root
gather_facts: no
...

$ ansible-pull --accept-host-key --directory /var/lib/ansible/local --full

I assume that ansible-pull is only suitable when adressing the local host?
Or what might be done to re-use the push playbooks in pull mode?
Thanks, Raulo
