WordPress Operator

A Juju charm for a Kubernetes deployment of WordPress, configurable to use a MySQL backend.


WordPress powers more than 39% of the web — a figure that rises every day. Everything from simple websites, to blogs, to complex portals and enterprise websites, and even applications, are built with WordPress. WordPress combines simplicity for users and publishers with under-the-hood complexity for developers. This makes it flexible while still being easy-to-use.


For details on using Kubernetes with Juju see here, and for details on using Juju with MicroK8s for easy local testing see here.

To deploy the charm and relate it to the MariaDB K8s charm within a Juju Kubernetes model:

juju deploy charmed-osm-mariadb-k8s mariadb
juju deploy wordpress-k8s
juju relate wordpress-k8s mariadb:mysql

It will take about 5 to 10 minutes for Juju hooks to discover the site is live and perform the initial setup for you. Once the "Workload" status is "active", your WordPress site is configured.

To retrieve the auto-generated admin password, run the following:

juju run-action --wait wordpress-k8s/0 get-initial-password

You should now be able to browse to the IP address of the unit. Here's some sample output from juju status:

Unit                Workload     Agent  Address      Ports     Message
mariadb/0*          active       idle  3306/TCP  ready
wordpress-k8s/0*    active       idle  80/TCP    Pod configured

In this case our UNIT_IP is If we visit http://${UNIT_IP}/ you'll see the WordPress site itself, or you can log in to the admin site at http://{$UNIT_IP}/wp-admin using a username of admin and the password from the get-initial-password action above.
