What is Drupal?

Drupal is one of the most versatile open source content management systems on the market. Drupal is built for high performance and is scalable to many servers, has easy integration via REST, JSON, SOAP and other formats, and features a whopping 15,000 plugins to extend and customize the application for just about any type of website.

TL;DR;

Docker Compose

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-drupal/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

Why use Bitnami Images?

  • Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
  • With Bitnami images the latest bug fixes and features are available as soon as possible.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
  • Bitnami images are built on CircleCI and automatically pushed to the Docker Hub.
  • All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading linux distribution.

Supported tags and respective Dockerfile links

NOTE: Debian 8 images have been deprecated in favor of Debian 9 images. Bitnami will not longer publish new Docker images based on Debian 8.

Prerequisites

To run this application you need Docker Engine 1.10.0. Docker Compose is recommended with a version 1.6.0 or later.

How to use this image

Run Drupal with a Database Container

Running Drupal with a database server is the recommended way. You can either use docker-compose or run the containers manually.

Run the application using Docker Compose

This is the recommended way to run Drupal. You can use the following docker-compose.yml template:

version: '2'

services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
      - MARIADB_USER=bn_drupal
      - MARIADB_DATABASE=bitnami_drupal
    volumes:
      - 'mariadb_data:/bitnami'
  drupal:
    image: 'bitnami/drupal:8'
    labels:
      kompose.service.type: nodeport
    environment:
      - MARIADB_HOST=mariadb
      - MARIADB_PORT_NUMBER=3306
      - DRUPAL_DATABASE_USER=bn_drupal
      - DRUPAL_DATABASE_NAME=bitnami_drupal
      - ALLOW_EMPTY_PASSWORD=yes
    ports:
      - '80:80'
      - '443:443'
    volumes:
      - 'drupal_data:/bitnami'
    depends_on:
      - mariadb
volumes:
  mariadb_data:
    driver: local
  drupal_data:
    driver: local

Run the application manually

If you want to run the application manually instead of using docker-compose, these are the basic steps you need to run:

  1. Create a new network for the application and the database:
$ docker network create drupal-tier
  1. Create a volume for MariaDB persistence and create a MariaDB container
$ docker volume create --name mariadb_data
$ docker run -d --name mariadb \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e MARIADB_USER=bn_drupal \
  -e MARIADB_DATABASE=bitnami_drupal \
  --net drupal-tier \
  --volume mariadb_data:/bitnami \
  bitnami/mariadb:latest
  1. Create volumes for Drupal persistence and launch the container
$ docker volume create --name drupal_data
$ docker run -d --name drupal -p 80:80 -p 443:443 \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e DRUPAL_DATABASE_USER=bn_drupal \
  -e DRUPAL_DATABASE_NAME=bitnami_drupal \
  --net drupal-tier \
  --volume drupal_data:/bitnami \
  bitnami/drupal:latest

Access your application at http://your-ip/

Persisting your application

If you remove the container all your data and configurations will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a volume at the /bitnami path. Additionally you should mount a volume for persistence of the MariaDB data.

The above examples define docker volumes namely mariadb_data and drupal_data. The Drupal application state will persist as long as these volumes are not removed.

To avoid inadvertent removal of these volumes you can mount host directories as data volumes. Alternatively you can make use of volume plugins to host the volume data.

Mount host directories as data volumes with Docker Compose

This requires a minor change to the docker-compose.yml template previously shown:

version: '2'

services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
      - MARIADB_USER=bn_drupal
      - MARIADB_DATABASE=bitnami_drupal
    volumes:
      - '/path/to/mariadb-persistence:/bitnami'
  drupal:
    image: 'bitnami/drupal:latest'
    depends_on:
      - mariadb
    ports:
      - '80:80'
      - '443:443'
    environment:
      - DRUPAL_DATABASE_USER=bn_drupal
      - DRUPAL_DATABASE_NAME=bitnami_drupal
      - ALLOW_EMPTY_PASSWORD=yes
    volumes:
      - '/path/to/drupal-persistence:/bitnami'

Mount host directories as data volumes using the Docker command line

  1. Create a network (if it does not exist):
$ docker network create drupal-tier
  1. Create a MariaDB container with host volume:
$ docker run -d --name mariadb \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e MARIADB_USER=bn_drupal \
  -e MARIADB_DATABASE=bitnami_drupal \
  --net drupal-tier \
  --volume /path/to/mariadb-persistence:/bitnami \
  bitnami/mariadb:latest

Note: You need to give the container a name in order to Drupal to resolve the host

  1. Create the Drupal container with host volumes:
$ docker run -d --name drupal -p 80:80 -p 443:443 \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e DRUPAL_DATABASE_USER=bn_drupal \
  -e DRUPAL_DATABASE_NAME=bitnami_drupal \
  --net drupal-tier \
  --volume /path/to/drupal-persistence:/bitnami \
  bitnami/drupal:latest

Upgrade this application

Bitnami provides up-to-date versions of MariaDB and Drupal, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. We will cover here the upgrade of the Drupal container. For the MariaDB upgrade see https://github.com/bitnami/bitnami-docker-mariadb/blob/master/README.md#upgrade-this-image

  1. Get the updated images:
$ docker pull bitnami/drupal:latest
  1. Stop your container
  • For docker-compose: $ docker-compose stop drupal
  • For manual execution: $ docker stop drupal
  1. Take a snapshot of the application state
$ rsync -a /path/to/drupal-persistence /path/to/drupal-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)

Additionally, snapshot the MariaDB data

You can use these snapshots to restore the application state should the upgrade fail.

  1. Remove the stopped container
  • For docker-compose: $ docker-compose rm drupal
  • For manual execution: $ docker rm drupal
  1. Run the new image
  • For docker-compose: $ docker-compose up drupal
  • For manual execution (mount the directories if needed): docker run --name drupal bitnami/drupal:latest

Configuration

Environment variables

When you start the drupal image, you can adjust the configuration of the instance by passing one or more environment variables either on the docker-compose file or on the docker run command line. If you want to add a new environment variable:

  • For docker-compose add the variable name and value under the application section:
drupal:
  image: bitnami/drupal:latest
  ports:
    - 80:80
    - 443:443
  environment:
    - DRUPAL_PASSWORD=my_password
  • For manual execution add a -e option with each variable and value:
$ docker run -d --name drupal -p 80:80 -p 443:443 \
  -e DRUPAL_PASSWORD=my_password \
  --net drupal-tier \
  --volume /path/to/drupal-persistence:/bitnami \
  bitnami/drupal:latest
