Joomla! is a PHP content management system (CMS) for publishing web content. It includes features such as page caching, RSS feeds, printable versions of pages, news flashes, blogs, search, and support for language international.

TL;DR;

$ helm install stable/joomla

Introduction

This chart bootstraps a Joomla! deployment on a Kubernetes cluster using the Helm package manager.

It also packages the Bitnami MariaDB chart which bootstraps a MariaDB deployment required by the Joomla! application.

Prerequisites

Kubernetes 1.4+ with Beta APIs enabled
PV provisioner support in the underlying infrastructure

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/joomla

The command deploys Joomla! on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip

: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Configuration

The following table lists the configurable parameters of the Joomla! chart and their default values.

`externalDatabase.host`	Host of the external database	`nil`
`externalDatabase.port`	Port of the external database	`3306`
`externalDatabase.user`	Existing username in the external db	`bn_joomla`
`externalDatabase.password`	Password for the above username	`nil`
`externalDatabase.database`	Name of the existing database	`bitnami_joomla`
`mariadb.enabled`	Whether to use the MariaDB chart	`true`
`mariadb.mariadbDatabase`	Database name to create	`bitnami_joomla`
`mariadb.mariadbUser`	Database user to create	`bn_joomla`
`mariadb.mariadbPassword`	Password for the database	`nil`
`mariadb.mariadbRootPassword`	MariaDB admin password	`nil`
`serviceType`	Kubernetes Service type	`LoadBalancer`
`persistence.enabled`	Enable persistence using PVC	`true`
`persistence.apache.storageClass`	PVC Storage Class for Apache volume	`nil` (uses alpha storage annotation)
`persistence.apache.accessMode`	PVC Access Mode for Apache volume	`ReadWriteOnce`
`persistence.apache.size`	PVC Storage Request for Apache volume	`1Gi`
`persistence.joomla.storageClass`	PVC Storage Class for Joomla! volume	`nil` (uses alpha storage annotation)
`persistence.joomla.accessMode`	PVC Access Mode for Joomla! volume	`ReadWriteOnce`
`persistence.joomla.size`	PVC Storage Request for Joomla! volume	`8Gi`
`resources`	CPU/Memory resource requests/limits	Memory: `512Mi`, CPU: `300m`

The above parameters map to the env variables defined in bitnami/joomla. For more information please refer to the bitnami/joomla image documentation.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name my-release \
  --set joomlaUsername=admin,joomlaPassword=password,mariadb.mariadbRootPassword=secretpassword \
    stable/joomla

The above command sets the Joomla! administrator account username and password to admin and password respectively. Additionally it sets the MariaDB root user password to secretpassword.

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

$ helm install --name my-release -f values.yaml stable/joomla

Tip

: You can use the default values.yaml

Persistence

The Bitnami Joomla! image stores the Joomla! data and configurations at the /bitnami/joomla and /bitnami/apache paths of the container.

Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube. See the Configuration section to configure the PVC or to disable persistence.
