I've got a case where I'd like to delegate contents of entire role over to
another box. Adding "delegate_to" to every task seems strenuous and not
reusable since I may use this role without delegation.
My attempt at simulating what is done with { role: X, tags: A } did not
succeed:
$ cat roles/delegated_role/tasks/main.yml
---
- name: Simple echo
shell: hostname
# delegate_to: "{{ central_server }}"
$ cat test_delegate.yml
---
- hosts: all
roles:
- { role: delegated_role, delegate_to: "{{ central_server }}" }
yet invocation with
$ ansible-playbook -vvv -u root -e 'central_server=foo.bar' -i inventory
test_delegate.yml
yields results obtained from the server mentioned and not from
'delegated_to'. Obviously uncommenting "delegate_to" line within a role
yields desired results but that means I can't reuse and it's a copy-paste
exercise to transfer a role into a delegated role.
Am I doing it the wrong way? Am I applying a wrong pattern here or is there
a different way to blanket-apply things like that?
