mysql-innodb-cluster and mysql-router
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The 20.05 OpenStack Charms release introduces two new supported charms to deploy
MySQL 8 for OpenStack: mysql-innodb-cluster and mysql-router.
These two charms will replace the percona-cluster charm completely for Ubuntu
20.04 LTS (Focal) and newer deployments.
The mysql-innodb-cluster charm deploys MySQL 8 in an InnoDB cluster with a
read/write node and N number of read-only nodes. This charm does not support
single-unit or non-clustered deployments.
The mysql-router charm deploys MySQL 8 mysqlrouter which will proxy database
requests from the principle charm application to a MySQL 8 InnoDB cluster.
MySQL Router handles cluster communication and understands the cluster schema.
The mysql-router charm is deployed as a subordinate on the principle charm
application and should be named accordingly at deploy time (e.g.
<application-name>-mysql-router).
A simple example deployment:
.. code-block:: none
juju deploy keystone
juju deploy mysql-router keystone-mysql-router
juju deploy -n 3 mysql-innodb-cluster
juju add-relation keystone-mysql-router:shared-db keystone:shared-db
juju add-relation keystone-mysql-router:db-router mysql-innodb-cluster:db-router
A more complex exmple bundle is available in `OpenStack bundles Focal Ussuri`_.
In Ubuntu 20.04 LTS (Focal) percona-cluster will no longer be available. The
migration process is documented in the Series Specific Procedures section of
the `Series upgrade`_ document.
