MySQL operators

Description

The Charmed MySQL Server is a database operator build for the Juju framework. It can be deployed on bare metal (using a LXD controller) or on Kubernetes (using a microk8s controller).

Usage

Deploying this charm depends on the substrate of choice

Kubernetes

juju add-model mysql
juju deploy mysql-k8s --channel 8.4/stable
juju status --watch 1s

Bare metal

juju add-model mysql
juju deploy mysql --channel 8.4/stable
juju status --watch 1s

To remove the deployment, run:

juju destroy-model mysql --destroy-storage --yes

Documentation

See the official documentation for more operational guidance, such as deployment on specific clouds, TLS, monitoring, backups, and troubleshooting.

Relations

Relations are the standard way to interconnect multiple Juju operators. There relations are defined over well-defined interfaces, that both requirer and provider operators must support.

Example:

juju add-model mysql
juju deploy mysql --channel 8.4/stable
juju deploy mysql-test-app

# Relate MySQL with your application
juju relate mysql:database mysql-test-app:database

Interfaces:

• mysql_client: standard interface to connect to the database.

Contributing

To build the charms:

(cd kubernetes && charmcraft pack)
(cd machines && charmcraft pack)

Please see the Juju SDK docs for guidelines on enhancements to this charm following best practice guidelines, and CONTRIBUTING.md for further developer guidance.
