Uninstalling a cluster on RHOSP from your own infrastructure

The Ansible playbooks that simplify the removal process on user-provisioned infrastructure require several Python modules. On the machine where you will run the process, add the modules’ repositories and then download them.

Prerequisites

• Python 3 is installed on your machine.

Procedure

1. On a command line, add the repositories:

   1. Register with Red Hat Subscription Manager:

   2. Pull the latest subscription data:

   3. Add the required repositories:

      $ sudo subscription-manager repos \
        --enable=rhel-8-for-x86_64-baseos-rpms \
        --enable=openstack-16-tools-for-rhel-8-x86_64-rpms \
        --enable=rhel-8-for-x86_64-appstream-rpms

2. Install the modules:

Removing a cluster from RHOSP that uses your own infrastructure

You can remove an OKD cluster on Red Hat OpenStack Platform (RHOSP) that uses your own infrastructure. To complete the removal process quickly, run several Ansible playbooks.

Prerequisites

• Python 3 is installed on your machine.

• You have the playbooks that you used to install the cluster.

• You modified the playbooks that are prefixed with down- to reflect any changes that you made to their corresponding installation playbooks. For example, changes to the bootstrap.yaml file are reflected in the down-bootstrap.yaml file.

• All of the playbooks are in a common directory.

Procedure

1. On a command line, run the playbooks that you downloaded:
