Ansible check hosts file

Question

Ansible: 2.9

I search a command or option how to check consistency between my "hosts" inventory file vs. group_vars tree fs.

I explain:

• My Host file:

[all]
N01
N02
S01
S02

[zone1]
N01
N02

[zone2]
S01
S02

[zone3]
Z01
Z02

• Group_vars tree FS:

PlayBook_dir
\__group_vars:
   - zone1.yml
   - zone2.yml

• Desired, make a Test with this check:

When I launch my Playbook he show a similar of "Error No zone3 in group_var dir tree".

You know for this or other tests?

Thank's!

You could have a play on localhost that checks for the existence of the group_vars files using the stat module. The results of this can be checked with assert.

    # First stat the path for file existence by looping over inventory groups
    - stat:
        path: "{{ playbook_dir }}/group_vars/{{ item.key }}.yml"
      loop: "{{ groups | dict2items }}"
      register: gvars

    # Loop over the registered variable and fail assertion if path doesn't exist
    - assert:
        that:
        - item.stat.exists
        fail_msg: "{{ item.invocation.module_args.path }} does not exist"
      when:
        - item.item.key not in ["all", "ungrouped"]
      loop: "{{ gvars.results }}"
      loop_control:
        label: "{{ item.item.key }}"
