Drupal Docker Container

Drupal is a content management system (CMS) that allows you create dynamic web sites. It can be somewhat difficult to install because it has a lot of dependencies. Using a docker container to perform the install makes the installation process easier.

Also, see Using Drupal and DITA OT to Create a PDF File for a Drupal use case.

Docker-compose.yml:

# Database username: postgres
# Database password: example
# ADVANCED OPTIONS; Database host: postgres
#

version: '3.1'

services:

  drupal:
    image: my-drupal:latest
    ports:
      - 8080:80
    volumes:
      - modules:/var/www/html/modules
      - profiles:/var/www/html/profiles
      - themes:/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
      - sites:/var/www/html/sites
    restart: none

  postgres:
    image: postgres:16
    environment:
      POSTGRES_PASSWORD: example
    restart: none
    volumes:

I created my own image (see Dockerfile that follows) to include Composer and the REST UI module.

Dockerfile:

FROM drupal:latest

# Install Composer
COPY --from=composer/composer:latest-bin /composer /usr/local/bin/composer

# Install REST UI module
RUN composer require drupal/restui

ENV DRUSH_VERSION 8.4.9
RUN curl -L --silent https://github.com/drush-ops/drush/releases/download/${DRUSH_VERSION}/drush.phar \
  > /usr/local/bin/drush && chmod +x /usr/local/bin/drush

Here's the command to build the docker image:

docker build -t my-drupal:latest .

Use PostgreSQl as the database type.

Use postgres as the database name.

Use postgres as the database user name.

Use example as the database password.

Use postgres as the host.

Use 5432 as the port number.
