Scenario: default

Driver: docker
Example default playbook
- name: Converge
  hosts: all
  roles:
  - role: tripleo_redhat_enforce

Description

This role is for OSP, the downstream version of tripleo and shouldn’t be used with other OS as it required the host to be subscribed.

It enforces policies regarding rhel version and subscribed channel according to the OSP version used.

This module hosts those requirements, so that we prevent update to wrong rhel release or subscription to wrong channels.

Currently it only implements a basic check to the subscribed rhel version.

This check has some fail-safe logic to avoid crashing the update on temporary network issue when running subscription-manager.

We are avoiding the validation framework as this can be easily disabled and we want this enforcement to be mandatory as this could lead user to unsupported combination of OSP/RHEL.

For upstream that change is transparent as the tasks are skipped if the ansible_distribution is not Red Hat.

Usage

Very simple usage, just pass the right parameter for the version you plan to check.

Remember this won’t have any effects on anything else than a Red Hat subscribed host.
