README.md

Overview

This charm provides a MySQL 8 InnoDB clustered database.

Ubuntu 19.10 or above is required.

Usage

The charm is intended for deploying a cluster and therefore does not deploy on a single unit.

Cluster deployment

juju deploy -n 3 mysql-innodb-cluster

The charm is designed to be used with the db-router relation in conjunction with the MySQL Router charm:

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.

Configuration

The name of the cluster can be customized at deploy time:

juju deploy -n 3 mysql-innodb-cluster --config cluster-name myCluster
