MySQL InnoDB Cluster Charm deploys and manages the lifecycle of a MySQL InnoDB Cluster.
This charm provides a MySQL 8 InnoDB clustered database.
Ubuntu 19.10 or above is required.
The charm is intended for deploying a cluster and therefore does not deploy on a single unit.
juju deploy -n 3 mysql-innodb-cluster
juju add-relation mysql-innodb-cluster:db-router msyql-router:db-router
The charm can be related to existing charms that use the shared-db relation. However, this relation should be considered deprecated:
juju add-relation mysql-innodb-cluster:shared-db keystone:shared-db
Scale out Usage
Nodes can be added to the cluster as Read Only nodes:
juju add-unit mysql-innodb-cluster
Known Limitations and Issues
Warning: This charm is in preview state.
The charm is under active development and is not yet production ready. Its current intended use is for validation of MySQL 8 InnoDB cluster for use with OpenStack.
The name of the cluster can be customized at deploy time:
juju deploy -n 3 mysql-innodb-cluster --config cluster-name myCluster

- (boolean) If True enables openstack upgrades for this charm via juju actions. You will still need to set openstack-origin to the new repository but instead of an upgrade running automatically across all units, it will wait for you to execute the openstack-upgrade action for this charm on each unit. If False it will revert to existing behavior of upgrading all units on config change.
