--- other: - | Add the ``ContainerImagePrepareLogFile`` heat parameter, which points to a log file to store outputs of the ``openstack tripleo container image prepare`` commands invoked by ansible for containers registry deployments. As it takes quite a while to finish, and may be retrying intermittent failures, make the command to log ``--verbose`` details as well. The default log file ``tripleo-container-image-prepare.log`` will be placed in the directory containing downloaded ansible playbooks and inventory files. For undercloud deployments, logs destination is shared with the default ``install-undercloud.log`` file.
