check_uc_hostname

About the role

Ansible role to check DockerInsecureRegistryAddress matches the UC hostname.

The purpose of this validation is mostly target for the FFWD 13 to 16.X procedure.

Customer is expected to follow the step 9.3. Configuring access to the undercloud registry

The customer needs to retrieve the control plane host name on the undercloud and add it into the DockerInsecureRegistryAddress.

It might happen that the user misses this step or doesn't really add the right control plan host name and then podman fails to retrieve the containers.

To summarize what customer is expected to do:

• Run sudo hiera container_image_prepare_node_names to get host name(s)
• Edit the containers-prepare-parameter.yaml file and the DockerInsecureRegistryAddress parameter with host name and IP of the undercloud.

This validation will:

• Pull DockerInsecureRegistryAddress (list) from the Openstack environment
• Run sudo hiera container_image_prepare_node_names
• Verify the container_image_prepare_node_names returned from hiera is contained in the DockerInsecureRegistryAddress list.

Requirements

This role will be executed pre Overcloud Update.
