Quick reference

What is Drupal?

Drupal is a free and open-source content-management framework written in PHP and distributed under the GNU General Public License. It is used as a back-end framework for at least 2.1% of all Web sites worldwide ranging from personal blogs to corporate, political, and government sites including and It is also used for knowledge management and business collaboration.

How to use this image

The basic pattern for starting a drupal instance is:

$ docker run --name some-drupal -d arm32v5/drupal

If you'd like to be able to access the instance from the host without the container's IP, standard port mappings can be used:

$ docker run --name some-drupal -p 8080:80 -d arm32v5/drupal

Then, access it via http://localhost:8080 or http://host-ip:8080 in a browser.

There are multiple database types supported by this image, most easily used via standard container linking. In the default configuration, SQLite can be used to avoid a second container and write to flat-files. More detailed instructions for different (more production-ready) database types follow.

When first accessing the webserver provided by this image, it will go through a brief setup process. The details provided below are specifically for the "Set up database" step of that configuration process.


$ docker run --name some-drupal --link some-mysql:mysql -d arm32v5/drupal
  • Database type: MySQL, MariaDB, or equivalent
  • Database name/username/password: <details for accessing your MySQL instance> (MYSQL_USER, MYSQL_PASSWORD, MYSQL_DATABASE; see environment variables in the description for mysql)
  • ADVANCED OPTIONS; Database host: mysql (for using the /etc/hosts entry added by --link to access the linked container's MySQL instance)


$ docker run --name some-drupal --link some-postgres:postgres -d arm32v5/drupal
  • Database type: PostgreSQL
  • Database name/username/password: <details for accessing your PostgreSQL instance> (POSTGRES_USER, POSTGRES_PASSWORD; see environment variables in the description for postgres)
  • ADVANCED OPTIONS; Database host: postgres (for using the /etc/hosts entry added by --link to access the linked container's PostgreSQL instance)


By default, this image does not include any volumes. There is a lot of good discussion on this topic in docker-library/drupal#3, which is definitely recommended reading.

There is consensus that /var/www/html/modules, /var/www/html/profiles, and /var/www/html/themes are things that generally ought to be volumes (and might have an explicit VOLUME declaration in a future update to this image), but handling of /var/www/html/sites is somewhat more complex, since the contents of that directory do need to be initialized with the contents from the image.

If using bind-mounts, one way to accomplish pre-seeding your local sites directory would be something like the following:

$ docker run --rm arm32v5/drupal tar -cC /var/www/html/sites . | tar -xC /path/on/host/sites

This can then be bind-mounted into a new container:

$ docker run --name some-drupal --link some-postgres:postgres -d \
    -v /path/on/host/modules:/var/www/html/modules \
    -v /path/on/host/profiles:/var/www/html/profiles \
    -v /path/on/host/sites:/var/www/html/sites \
    -v /path/on/host/themes:/var/www/html/themes \

Another solution using Docker Volumes:

$ docker volume create drupal-sites
$ docker run --rm -v drupal-sites:/temporary/sites arm32v5/drupal cp -aRT /var/www/html/sites /temporary/sites
$ docker run --name some-drupal --link some-postgres:postgres -d \
    -v drupal-modules:/var/www/html/modules \
    -v drupal-profiles:/var/www/html/profiles \
    -v drupal-sites:/var/www/html/sites \
    -v drupal-themes:/var/www/html/themes \

... via docker stack deploy or docker-compose

Example stack.yml for drupal:

# Drupal with PostgreSQL
# Access via "http://localhost:8080"
#   (or "http://$(docker-machine ip):8080" if using docker-machine)
# During initial Drupal setup,
# Database type: PostgreSQL
# Database name: postgres
# Database username: postgres
# Database password: example
# ADVANCED OPTIONS; Database host: postgres

version: '3.1'


    image: drupal:8-apache
      - 8080:80
      - /var/www/html/modules
      - /var/www/html/profiles
      - /var/www/html/themes
      # this takes advantage of the feature in Docker that a new anonymous
      # volume (which is what we're creating here) will be initialized with the
      # existing content of the image at the same location
      - /var/www/html/sites
    restart: always

    image: postgres:10
      POSTGRES_PASSWORD: example
    restart: always

Run docker stack deploy -c stack.yml drupal (or docker-compose -f stack.yml up), wait for it to initialize completely, and visit http://swarm-ip:8080, http://localhost:8080, or http://host-ip:8080 (as appropriate). When installing select postgres as database with the following parameters: dbname=postgres user=postgres pass=example hostname=postgres

Adding additional libraries / extensions

This image does not provide any additional PHP extensions or other libraries, even if they are required by popular plugins. There are an infinite number of possible plugins, and they potentially require any extension PHP supports. Including every PHP extension that exists would dramatically increase the image size.

If you need additional PHP extensions, you'll need to create your own image FROM this one. The documentation of the php image explains how to compile additional extensions. Additionally, the drupal:7 Dockerfile has an example of doing this.

The following Docker Hub features can help with the task of keeping your dependent images up-to-date:

  • Automated Builds let Docker Hub automatically build your Dockerfile each time you push changes to it.
  • Repository Links can ensure that your image is also rebuilt any time drupal is updated.
