Add support for deploying OVN SB relays [1]. This is enabled by default to improve large scale scenarios. Default mechanism deploys one relay group per 50 ovn-controller hosts and uses random but idempotent method to choose a relay for a given host. neutron-server and Octavia will connect directly to SB cluster, not via the relays. kolla-ansible check subcommand does not support ,,iterated'' containers for now - but will be introduced in a subsequent patch.

Adds support for deploying ``ovn-sb-db-relay``. By default, Kolla
|
|
automatically calculates the number of relay groups based on the size of
|
|
the ``ovn-controller`` group and the value of
|
|
``ovn_sb_db_relay_compute_per_relay`` (50 by default), rounding up. If you
|
|
do not want to use relays, set ``enable_ovn_sb_db_relay`` to ``no`` in
|
|
``globals.yml``.
|
|
upgrade:
|
|
- |
|
|
When upgrading, the new ``ovn-sb-db-relay`` containers are automatically
|
|
deployed unless you explicitly set ``enable_ovn_sb_db_relay`` to ``no``.
|
|
There are no special data migration or manual steps required to enable
|
|
``ovn-sb-db-relay``; it coexists alongside the existing OVN SB DB cluster.
