How should a game be included for playback other than offline?

Question

I have two players that run on the remote host ( 10.233.84.58). When run offline ( ansible-playbook -i inventory.txt playbook.yml), they work fine.

The first playbook includes the second, which is identical, except, obviously, for include:

---
- hosts: all
  tasks:
    - debug: msg="hello form playbook1"
    # up to now the content is identical between playbook1.yaml and playbook2.yaml
    # without the next line the playbook runs fine
    - include: playbook2.yml

When I ran playbook1.yml:

# ansible-playbook -i inventory.txt playbook1.yml                                                                (master✱)

PLAY [all] *********************************************************************

TASK [setup] *******************************************************************
ok: [10.233.84.58]

TASK [debug] *******************************************************************
ok: [10.233.84.58] => {
    "msg": "hello form playbook1"
}

TASK [include] *****************************************************************
fatal: [10.233.84.58]: FAILED! => {"failed": true, "reason": "no action detected in task.

NO MORE HOSTS LEFT *************************************************************
        to retry, use: --limit @playbook1.retry

PLAY RECAP *********************************************************************
10.233.84.58               : ok=2    changed=0    unreachable=0    failed=1

I extracted the “reason” from the error message above and made it more readable:

no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to have been in '/root/tests/playbook2.yml': line 2, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

---
- hosts: all
  ^ here

Answer 1

There are two types of include. You can include a playbook or task list.

---
- hosts: all
  tasks:
    - include: list_of_tasks.yml

- include: complete_playbook.yml

playbook2.yml .
include , - hosts, .
