From 5eef6ddf23a0cb5f5313351eaa305b54664dbdc2 Mon Sep 17 00:00:00 2001 From: Rich Megginson Date: Wed, 29 Nov 2023 13:01:39 -0700 Subject: [PATCH] refactor: improve support for ostree systems The dependency on `ansible.utils.update_fact` is causing issue with some users who now must install that collection in order to run the role, even if they do not care about ostree. The fix is to stop trying to set `ansible_facts.pkg_mgr`, and instead force the use of the ostree package manager with the `package:` module `use:` option. The strategy is - on ostree systems, set the flag `__$ROLENAME_is_ostree` if the system is an ostree system. The flag will either be undefined or `false` on non-ostree systems. Then, change every invocation of the `package:` module like this: ```yaml - name: Ensure required packages are present package: name: "{{ __$ROLENAME_packages }}" state: present use: "{{ (__$ROLENAME_is_ostree | d(false)) | ternary('ansible.posix.rhel_rpm_ostree', omit) }}" ``` This should ensure that the `use:` parameter is not used if the system is non-ostree. The goal is to make the ostree support as unobtrusive as possible for non-ostree systems. The user can also set `__$ROLENAME_is_ostree: true` in the inventory or play if the user knows that ostree is being used and wants to skip the check. Or, the user is concerned about the performance hit for ostree detection on non-ostree systems, and sets `__$ROLENAME_is_ostree: false` to skip the check. The flag `__$ROLENAME_is_ostree` can also be used in the role or tests to include or exclude tasks from being run on ostree systems. This fix also improves error reporting in the `get_ostree_data.sh` script when included roles cannot be found.
