redhat-subscription

Red Hat Subscription

An opinionated role using ansible modules redhat_subscription and rhsm_repository (new in Ansible 2.5) to allow for the easy registration of a host. Supports using either (activation key, organisation id) or (username, password) combinations.

In addition to registration, repositories can be disabled and/or enabled during execution of this role.

Note that this role has been developed for convenience in majority simple use case. And is not intended to be a catch-all role for subscription management.

Requirements

No additional requirements are enforced other than an an Ansbile version greater than 2.5. Development was done on Ansible 2.5+.

Role Variables

This role supports the following configurations via variables.

redhat_subscription_org_id: Subscription organisation ID. If using an activation key, this is required.
redhat_subscription_activationkey: Activation key to use for host registration.
redhat_subscription_username: If not using an activation key, specify Red Hat username.
redhat_subscription_password: If not using an activation key, specify Red Hat password. This is required if using credentials to register the host.
redhat_subscription_state: This variable can be used to specify if you want the subscription removed or added. This is passed directly to the state argument of the redhat_subscription module. Defaults to present.
redhat_subscription_pool_regex: Pool regex to use when registering the host. This is passed directly to the state argument of the redhat_subscription module. Defaults to ^$.
redhat_subscription_auto_attach: Supported only when using credentials to register. Defaults to no.
redhat_subscription_disable_repos: Repositories to disable. Defaults to [].
redhat_subscription_enable_repos: Repositories to enable. Defaults to [].
redhat_subscription_enable_explicit_repos_only: This flag, if set, will explicitly disable all repositories that are not specified in redhat_subscription_enable_repos.
redhat_subscription_skip_prereq: Skip all prerequisite checks.
redhat_subscription_force: Force registration. This is passed through to the underlying ansible module.
redhat_subscription_retry: Number of times to retry registering the host. Defaults to 0.

Dependencies

No Dependencies required other than Ansible itself.

Example Playbook

Here is an example play that implements the Host Preparation steps associated with an OpenShift 3.9 cluster.

        redhat_subscription_activationkey: foobar-activation-key
        redhat_subscription_pool_regex: "^.*OpenShift.*$"
        redhat_subscription_enable_explicit_repos_only: "yes"
        redhat_subscription_disable_repos: []
