Enabling delegate_to on include_role via block

[Tim Diels]

Hi,

I noticed that while:

    - include_role:

        name: myrole

      delegate_to: somehost

will not delegate the included role, this will:

    - block:

        - include_role:

            name: myrole

      delegate_to: somehost

Is this by design, i.e. I may rely on it, or is this a fluke that may get 'fixed' in future releases?

Best regards,

Tim

By delegating the included role I mean delegating the tasks inside the role and any more included/imported by that role or even tasks of roles the role depends on (I tested this on ansible 2.7.10).

Analog for tags it turns out that:

    - block:

        - include_role:

            name: myrole

      tags: mytag

will apply the tag to tasks inside the role, its dependencies, roles that it includes/imports. Is this too a feature?

The block trick also works for include_tasks and import_tasks for both setting tags and delegate_to.

This is expected. There is documentation to this effect at 

https://docs.ansible.com/ansible/latest/porting_guides/porting_guide_2.5.html#dynamic-includes-and-attribute-inheritance

As of Ansible 2.7 see the "apply" argument to include_tasks and include_role to do what you want.
