A cleanup playbook for 3scale
If you are running integration tests embedding 3scale or are doing a lot of 3scale demos, you might sooner or later have plenty of services declared in the 3scale Admin console, which could reveal difficult to work with. And with the new feature named API-as-a-Product, there are now Backends and Products to delete, making the cleanup by hand a bit tedious.

Check the Ansible version number in a playbook
My Ansible playbooks sometimes use features that are available only in a very recent versions of Ansible. To prevent unecessary troubles to the team mates that will execute them, I like to add a task at the very beginning of my playbooks to check the Ansible version number and abort if the requirements are not met.

However, for some customers this is not secure enough. Most of them would rather download all the images locally (using oc adm release mirror ?), transport them on a removable media to the internal network and provision the target registry.

Solving the Ansible error 'This module requires the OpenShift Python client'
If you are using MacOS to develop Operators based on Ansible or simply running Ansible playbooks straight from your Mac, you might encounter this error: This module requires the OpenShift Python client.
