Short Description
A customizable Drupal 7.x image.
Full Description

Drupal image without database

This image contains the latest stable Drupal 7-release. It will automatically
setup the database and install a default site.

The image doesn't contain a database so you have to create a seperate database
container (which is no effort if you use the provided configuration for
docker-compose) and link this container or pass the database information of a
MySQL- or Postgres-host.

Why create another Drupal image?

Many of the other Drupal images got a database baked in or didn't install
Drupal automatically and didn't offer much flexibility. This image can be
easily be used as base image for your own Drupal images see below Customization
by using Dockerfiles. At the same time you can just use this image for a
vanilla Drupal-experience that can be fully administered and extended via the
web-interface as well as with drush on the command-line.

Usage

If you want to launch a bare Drupal image with a MySQL backend you can do so:

docker run -d -e MYSQL_ROOT_PASSWORD="test123" --name db mysql
docker run -d --link db:mysql -p 80:80 samos123/drupal

Alternatively you can use Docker-Compose
in a directory that contains the provided docker-compose.yml:

docker-compose up

This will launch a new drupal site with a default theme and no additional
modules. If you want custom modules, see Customization.

As customizations and uploads are stored you must take care of these directories
if you want to keep these:

  • /var/www/html/sites (modules, themes, uploaded files)
  • /var/www/private (non-public files, e.g. to store backups)

As these folders are defined as volumes in the sample docker-compose.yml,
you can easily update your container to use the latest image while preserving
any modifications with:

docker-compose pull && docker-compose up -d

Database options

You can use a linked database-container with the alias mysql or postgres as
shown above - Drupal will be automatically configured to it. Or you use an
external database-host. Therefore pass the following environment variables to
your container:

  • DB_DRIVER
    • allowed values are mysql (default) and pgsql
  • DB_HOST
  • DB_PORT
    • default: 3306 if DB_DRIVER == 'mysql'
    • default: 5432 if DB_DRIVER == 'pgsql'
  • DB_NAME
    • default: drupal
  • DB_USER
    • default: root if DB_DRIVER == 'mysql'
    • default: postgres if DB_DRIVER == 'pgsql'
  • DB_PASS

Postgres

You can alternatively use a Postgres container. The configuration is very
similar to that of MySQL as seen in the docker-compose.yml file, with a
couple small changes.

There is an example docker-compose.yml available in the examples folder.

Other options

  • VIRTUAL_HOST - sets the ServerName-directive for httpd and Drupal's
    base_url configuration variable; handy in conjunction with
    jwilder/nginx-proxy
    • if it is a comma-seperated list, the first value is used
  • SERVERNAME - use this to explicitly set httpd's ServerName-directive
    • if none of these both variables are given, the /etc/hostname will be
      used
  • BASE_URL - explicitly set the base_url configuration variable for
    Drupal
    • trailing slashes are not allowed
  • BASE_URL_PROTO (default: https://) - if BASE_URL is derived from
    VIRTUAL_HOST, this will be prefixed as protocol
  • UPLOAD_LIMIT (default: 10M) - sets variables for the PHP-interpreter
    to control maximum upload sizes
  • MEMORY_LIMIT (default: 64M) - sets the memory_limit
    for the PHP-interpreter
  • ADMIN_USER (default: admin) - sets the administrator account name when
    creating a new instance
  • ADMIN_PASSWORD - (default: changeme) sets the administrator password when
    creating a new instance.

Customization

To create a customized Drupal-image, you can add/modify scripts in a derived
image or mount them in your container into these directories:
/scripts/setup.d and /scripts/pre-launch.d. Furthermore,

  • the scripts' name must start with two digits, the rest may consist of
    alphanumerics, _ and -
    • the scripts will be executed in alphanumerical order of their names
  • the scripts must be set executable (chmod a+x <scriptpath>)

See the folder examples
on how to use the Zen-template and the modules_filter-module and build an
image containing them.

Drush's system-wide configuration (/etc/drushrc.php) sets its default-
behaviour to be verbose (-v) and affirmative (--yes) in order to grant easy
and elaborated usage of scripts. If you want to change that behaviour in an
interactive environment or for certain sites (e.g. `docker exec -ti

<drupal_container> /bin/bash), change it in an [overridingdrushrc.php`-location](https://raw.githubusercontent.com/drush-ops/drush/master/examples/example.drushrc.php).

See the documentation of php:apache on
the usage of docker-php-ext-configure and docker-php-ext-install to install
PHP extensions.
