Depend variables default way to indicate source role name

[ypid]

Edited, current approved version

Various roles in DebOps expose dependency variables for other roles to use. Example ferm__dependent_rules of debops.ferm.

There have been a number of changes in the format how to do this.

The recommended format is:

  - something: 'something'
    by_role: 'ROLE_OWNER.ROLE_NAME'
# and
  - something: 'something'
    by_role:: 'debops.nginx'

This applies for all roles. Other keys like role are deprecated and might be used for other purposes later.
The role which exposes/provides dependency variables has to take care of properly sanitizing the role name. This can be done by replace(".", "_") in case the value is used as part of a file name.

@drybjed Or

  - something: 'something'
    role: 'debops.nginx'

?

[drybjed]

The use of debops.nginx is probably better since it's more explicit, and there could be other nginx roles in use.

[ypid]

It is just not widely used in DebOps yet. Probably also because file names are generated based on that. I would propose to sanitize the role (name) then with (replace(".", "_")). Sounds good?

[drybjed]

Sure, sounds good.

Updated my first comment with the currently approved version based on a discussion with @drybjed. Example:

  - something: 'something'
    by_role: 'ROLE_OWNER.ROLE_NAME'
# and
  - something: 'something'
    by_role:: 'debops.nginx'
