MySQL operators

Description

The Charmed MySQL Server is a database operator built for the Juju orchestrator. It can be deployed

• on bare metal (using a machine cloud, for instance LXD), or
• on Kubernetes (using a K8s cloud, for instance microk8s or Canonical K8s).

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. These 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 && charmcraftlocal pack)
(cd machines && charmcraftlocal 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.
