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 8.0/stable
juju status --watch 1s

Bare metal

juju add-model mysql
juju deploy mysql --channel 8.0/stable
juju status --watch 1s

To remove the deployment, run:

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

Documentation

Please follow the tutorial guide (K8s or VM) with detailed explanation how to access DB, configure cluster, change credentials and/or enable TLS.

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 8.0/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.
