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.

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 template:

version: '2'

services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    volumes:
      - 'mariadb_data:/bitnami/mariadb'
  drupal:
    image: 'bitnami/drupal:latest'
    ports:
      - '80:80'
      - '443:443'
    volumes:
      - 'drupal_data:/bitnami/drupal'
      - 'apache_data:/bitnami/apache'
    depends_on:
      - mariadb

volumes:
  mariadb_data:
    driver: local
  drupal_data:
    driver: local
  apache_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:

Create a new network for the application and the database:

$ docker network create drupal_network

Start a MariaDB database in the network generated:

$ docker run -d --name mariadb --net=drupal_network bitnami/mariadb

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

Run the Drupal container:

$ docker run -d -p 80:80 --name drupal --net=drupal_network bitnami/drupal

Then you can access your application at http://your-ip/

Persisting your application

If you remove every container and volume all your data will be lost, and the next time you run the image the application 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 of the Drupal deployment, the above examples define docker volumes namely mariadb_data, drupal_data and apache_data. The Drupal application state will persist as long as these volumes are not removed.

If 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.

Note! If you have already started using your application, follow the steps on backing up to pull the data from your running container down to your host.

Mount host directories as data volumes with Docker Compose

This requires a sightly modification from the docker-compose.yml template previously shown:

version: '2'

services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    volumes:
      - '/path/to/mariadb-persistence:/bitnami/mariadb'
  drupal:
    image: 'bitnami/drupal:latest'
    depends_on:
      - mariadb
    ports:
      - '80:80'
      - '443:443'
    volumes:
      - '/path/to/drupal-persistence:/bitnami/drupal'
      - '/path/to/apache-persistence:/bitnami/apache'

Mount host directories as data volumes using the Docker command line

In this case you need to specify the directories to mount on the run command. The process is the same than the one previously shown:

If you haven't done this before, create a new network for the application and the database:

$ docker network create drupal_network

Start a MariaDB database in the previous network:

$ docker run -d --name mariadb \
  --net drupal \
  --volume /path/to/mariadb-persistence:/bitnami/mariadb \
  bitnami/mariadb:latest

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

Run the Drupal container:

$ docker run -d -p 80:80 --name drupal -v /path/to/bitnami/drupal:/bitnami/drupal \
  --network=drupal_network bitnami/drupal \
  --volume /path/to/drupal-persistence:/bitnami/drupal \
  --volume /path/to/apache-persistence:/bitnami/apache \
  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

Get the updated images:

$ docker pull bitnami/drupal:latest

Stop your container

For docker-compose: $ docker-compose stop drupal
For manual execution: $ docker stop drupal

(For non-compose execution only) Create a backup if you have not mounted the drupal folder in the host.
Remove the currently running container

For docker-compose: $ docker-compose rm drupal
For manual execution: $ docker rm drupal

Run the new image

For docker-compose: $ docker-compose start 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
  environment:
    - DRUPAL_PASSWORD=my_password
  volumes_from:
    - application_data

For manual execution add a -e option with each variable and value:

 $ docker run -d -e DRUPAL_PASSWORD=my_password -p 80:80 --name drupal -v /your/local/path/bitnami/drupal:/bitnami/drupal --network=drupal_network bitnami/drupal

Available variables:

DRUPAL_USERNAME: Drupal application username. Default: user
DRUPAL_PASSWORD: Drupal application password. Default: bitnami
DRUPAL_EMAIL: Drupal application email. Default: user@example.com
MARIADB_USER: Root user for the MariaDB database. Default: root
MARIADB_PASSWORD: Root password for the MariaDB.
MARIADB_HOST: Hostname for MariaDB server. Default: mariadb
MARIADB_PORT: Port used by MariaDB server. Default: 3306

Backing up your application

To backup your application data follow these steps:

Stop the running container:

For docker-compose: $ docker-compose stop drupal
For manual execution: $ docker stop drupal

Copy the Drupal data folder in the host:

$ docker cp /your/local/path/bitnami:/bitnami/drupal

Restoring a backup

To restore your application using backed up data simply mount the folder with Drupal data in the container. See persisting your application section for more info.
