Description of problem: In order to make use of tripleo-ansible playbooks and roles in the OpenStack installed on OpenShift deployments, it is necessary to have an Ansible Execution Environment [a] container available. In order to facilitate the container build, there is a patch to do the build using our existing container build mechanism [b]. For OSP 18.0 we will want the EE container to contain the content from the tripleo-ansible stable/zed upstream repository. [a] https://docs.ansible.com/automation-controller/latest/html/userguide/execution_environments.html#building-an-ee [b] https://review.opendev.org/c/openstack/tripleo-common/+/776674 Expected results: An Ansible Execution Environment container with tripleo-ansible content from what is currently tripleo-ansible master, but will become tripleo-ansible stable/zed when that upstream release is cut.
