Overview
This charm provides a MySQL 8 Router. The charm proxies database requests from the principle application charm to a MySQL 8 InnoDB Cluster. MySQL Router handles cluster communication and understands the cluster schema.
Ubuntu 19.10 or above is required.
Usage
The charm is intended to be deployed as a subordinate charm on the application server and related to the mysql-innodb-cluster charm.
Cluster deployment
juju deploy mysql-router
The charm is related to a principle application charm via the shared-db relation:
juju add-relation keystone:shared-db mysql-router:shared-db
The charm is then related to the MySQL 8 InnoDB cluster charm via the db-router relation:
juju add-relation msyql-router:db-router mysql-innodb-cluster:db-router
Scale out Usage
Scale out is accomplished by adding units to the principle charm:
juju add-unit keystone
Known Limitations and Issues
Warning: This charm is in preview state.
