Having tagged plays allows us to easily run a subset of the plays for a command, and perform targeted operations with less risk of unintended consequences. The tags are typically named after the playbook, although some of the overcloud playbooks have been tagged without an overcloud- prefix.

# For some currently unknown reason, overcloud hosts end up with multiple
|
|
# entries in /etc/hosts that map their own hostname to their provisioning
|
|
# network IP address, in addition to one that maps their own hostname to their
|
|
# internal network IP address. This causes RabbitMQ upgrades to fail, as
|
|
# RabbitMQ expects the system's hostname to resolve to the IP address on
|
|
# which it is listening. As a workaround, we remove the stale entries from
|
|
# /etc/hosts. See https://github.com/stackhpc/kayobe/issues/14.
