Drupal

Drupal is one of the most versatile open source content management systems on the market.

TL;DR;

$ helm install stable/drupal

Introduction

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

It also packages the Bitnami MariaDB chart which is required for bootstrapping a MariaDB deployment for the database requirements of the Drupal 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/drupal

The command deploys Drupal 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 tables lists the configurable parameters of the Drupal chart and their default values.

Parameter	Description	Default
image	Drupal image	bitnami/drupal:{VERSION}
imagePullPolicy	Image pull policy	IfNotPresent
drupalUsername	User of the application	user
drupalPassword	Application password	random 10 character long alphanumeric string
drupalEmail	Admin email	user@example.com
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 class annotation)
persistence.apache.accessMode	PVC Access Mode for Apache volume	ReadWriteOnce
persistence.apache.size	PVC Storage Request for Apache volume	1Gi
persistence.drupal.storageClass	PVC Storage Class for Drupal volume	nil (uses alpha storage class annotation)
persistence.drupal.accessMode	PVC Access Mode for Drupal volume	ReadWriteOnce
persistence.drupal.size	PVC Storage Request for Drupal volume	8Gi
resources	CPU/Memory resource requests/limits	Memory: 512Mi, CPU: 300m

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

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

$ helm install --name my-release \
  --set drupalUsername=admin,drupalPassword=password,mariadb.mariadbRootPassword=secretpassword \
    stable/drupal

The above command sets the Drupal 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/drupal

Tip

: You can use the default values.yaml

Persistence

The Bitnami Drupal image stores the Drupal data and configurations at the /bitnami/drupal 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.
