Rotating spare Amphorae
-----------------------
.. warning::
Spares pool support is deprecated as of the Victoria release.
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.
Generating a List of Load Balancers to Rotate
---------------------------------------------
@ -242,32 +215,6 @@ show <loadbalancer id>`` until the load balancer goes ``ACTIVE`` again.
Best Practices/Optimizations
----------------------------
To speed up the failovers, the spare pool can be temporarily increased to
accommodate the rapid failover of the amphora. In this case after the
new image has been loaded into glance, shut down or initiate a failover of the
amphora in the spare pool. They can be found by listing amphorae in ``READY``
status:
.. code-block:: bash
openstack loadbalancer amphora list --status READY
After you have increased the spare pool size and restarted all Octavia
services, failovers will be greatly accelerated. To preserve resources,
restore the old settings and restart the Octavia services. Since Octavia won't
terminate superfluous spare amphora on its own, they can be left in the system
and will automatically be used up as new load balancers are created and/or
load balancers in error state are failed over.
.. warning::
If you are using the anti-affinity feature please be aware that it is
not compatible with spare pools and you are risking both the ACTIVE and
BACKUP amphora being scheduled on the same host. It is recommended to
not increase the spare pool during fail overs in this case (and not to use
the spare pool at all).
Since a failover puts significant load on the OpenStack installation by
creating new virtual machines and ports, it should either be done at a very
slow pace, during a time with little load, or with the right throttling
@ -392,10 +339,7 @@ Once this is changed Octavia can't read any heartbeats and will assume
all amphora are in an error state and initiate an immediate failover.
In preparation, read the chapter on :ref:`best_practice` in
the Failover section. In particular, it is advisable if the throttling
enhancement (available in Pike) doesn't exist to create a sufficient
number of spare amphorae to mitigate the stress on the OpenStack installation
when Octavia starts to replace all amphora immediately.

Given the risks involved with changing this key it should not be changed
during routine maintenance but only when a compromise is strongly suspected.

Spares pool considerations
^^^^^^^^^^^^^^^^^^^^^^^^^^
.. warning::
Spares pool support is deprecated as of the Victoria release.
One configuration directive deserves some extra consideration in this document:
Depending on the specifics of your production environment, you may decide to
run Octavia with a non-empty "spares pool." Since the time it takes to spin up
a new amphora can be non-trivial in some cloud environments (and the
reliability of such operations can sometimes be less than ideal), this
directive instructs Octavia to attempt to maintain a certain number of amphorae
running in an idle, unconfigured state. These amphora will run base amphora
health checks and wait for configuration from the Octavia controller. The
overall effect of this is to greatly reduce the time it takes and increase the
reliability of deploying a new load balancing service on demand. This comes at
the cost of having a number of deployed amphorae which consume resources but
are not actively providing load balancing services, and at the cost of not
being able to use Nova anti-affinity features for ACTIVE-STANDBY load
balancer topologies.
