Rotating spare Amphorae
-----------------------
If the spare pool is enabled in Octavia, spare amphorae must be rotated
first, so a new load balancer will use the new amphora image from a newly
spawned spare amphora.
To rotate spare amphorae, list the IDs of all amphorae in ``READY`` status:
.. code-block:: bash
openstack loadbalancer amphora list -c id -f value --status READY
Then, for each ID, perform the failover on the amphora:
.. code-block:: bash
openstack loadbalancer amphora failover <amphora id>
Spare amphorae now use the new amphora image, and those spare amphorae will be
used when creating a new load balancer or when performing a failover of a load
balancer.
