As version-check.yml is added to deploy.yml, we must make sure the tasks are only run when the rabbitmq container exists. Change-Id: Iaa31bae739110094affb5e402ed9ac40b153ac3d

Looks like you're trying to run a skip-release upgrade!
|
|
RabbitMQ must be at most one version behind the target release version ({{ rabbitmq_version_new.stdout | trim }}) to run this upgrade.
|
|
You are running {{ rabbitmq_version_current.stdout }}.
|
|
Please first upgrade to {{ upgrade_version }} with the command ``kolla-ansible rabbitmq-upgrade {{ upgrade_version }}``.
|
|

fail_msg: >

Looks like you're about to downgrade RabbitMQ from version {{ rabbitmq_version_current.stdout }} to version {{ rabbitmq_version_new.stdout | trim }}.
|
|
If you're absolutely certain you want to do this, please skip the tag `rabbitmq-version-check`.
|
|
Otherwise, see these docs for how to pin the version of RabbitMQ:
