October CMS build 420+ requires PHP version 7.0 or higher

Quick Start

To run October CMS using Docker, start a container using the latest image, mapping your local port 80 to the container's port 80:

$ docker run -p 80:80 --name october aspendigital/octobercms:latest
# `CTRL-C` to stop
$ docker rm october  # Destroys the container

If there is a port conflict, you will receive an error message from the Docker daemon. Try mapping to an open local port (-p 8080:80) or shut down the container or server that is on the desired port.

  • Visit http://localhost using your browser.
  • Login to the backend with the username admin and password admin.
  • Hit CTRL-C to stop the container. Running a container in the foreground will send log outputs to your terminal.

Run the container in the background by passing the -d option:

$ docker run -p 80:80 --name october -d aspendigital/octobercms:latest
$ docker stop october  # Stops the container. To restart `docker start october`
$ docker rm october  # Destroys the container

Working with Local Files

Using Docker volumes, you can mount local files inside a container.

The container uses the working directory /var/www/html for the web server document root. This is where the October CMS codebase resides in the container. You can replace files and folders, or introduce new ones with bind-mounted volumes:

# Developing a plugin
$ git clone git@github.com:aspendigital/oc-resizer-plugin.git
$ cd oc-resizer-plugin
$ docker run -p 80:80 --rm \
  -v $(pwd):/var/www/html/plugins/aspendigital/resizer \
  aspendigital/octobercms:latest

Save yourself some keyboards strokes, utilize docker-compose by introducing a docker-compose.yml file to your project folder:

# docker-compose.yml
version: '2.2'
services:
  web:
    image: aspendigital/octobercms
    ports:
      - 80:80
    volumes:
      - $PWD:/var/www/html/plugins/aspendigital/resizer

With the above example saved in working directory, run:

$ docker-compose up -d # start services defined in `docker-compose.yml` in the background
$ docker-compose down # stop and destroy

Database Support

SQLite

On build, an SQLite database is created and initialized for the Docker image. With that database, users have immediate access to the backend for testing and developing themes and plugins. However, changes made to the built-in database will be lost once the container is stopped and removed.

When projects require a persistent SQLite database, copy or create a new database to the host which can be used as a bind mount:

# Create and provision a new SQLite database:
$ touch storage/database.sqlite
$ docker run --rm \
  -v $(pwd)/storage/database.sqlite:/var/www/html/storage/database.sqlite \
  aspendigital/octobercms php artisan october:up

# Now run with the volume mounted to your host
$ docker run -p 80:80 --name october \
 -v $(pwd)/storage/database.sqlite:/var/www/html/storage/database.sqlite \
 aspendigital/octobercms

MySQL / Postgres

Alternatively, you can host the database using another container:

#docker-compose.yml
version: '2.2'
services:
  web:
    image: aspendigital/octobercms:latest
    ports:
      - 80:80
    environment:
      - DB_TYPE=mysql
      - DB_HOST=mysql #DB_HOST should match the service name of the database container
      - DB_DATABASE=octobercms
      - DB_USERNAME=root
      - DB_PASSWORD=root

  mysql:
    image: mysql:5.7
    ports:
      - 3306:3306
    environment:
      - MYSQL_ROOT_PASSWORD=root
      - MYSQL_DATABASE=octobercms

Provision a new database with october:up:

$ docker-compose up -d
$ docker-compose exec web php artisan october:up

Cron

You can start a cron process by setting the environment variable ENABLE_CRON to true:

$ docker run -p 80:80 -e ENABLE_CRON=true aspendigital/octobercms:latest

Separate the cron process into it's own container:

#docker-compose.yml
version: '2.2'
services:
  web:
    image: aspendigital/octobercms:latest
    init: true
    restart: always
    ports:
      - 80:80
    environment:
      - TZ=America/Denver
    volumes:
      - ./.env:/var/www/html/.env
      - ./plugins:/var/www/html/plugins
      - ./storage/app:/var/www/html/storage/app
      - ./storage/logs:/var/www/html/storage/logs
      - ./storage/database.sqlite:/var/www/html/storage/database.sqlite
      - ./themes:/var/www/html/themes

  cron:
    image: aspendigital/octobercms:latest
    init: true
    restart: always
    command: [cron, -f]
    environment:
      - TZ=America/Denver
    volumes_from:
      - web

Command Line Tasks

Run the container in the background and launch an interactive shell (bash) for the container:

$ docker run -p 80:80 --name containername -d aspendigital/octobercms:latest
$ docker exec -it containername bash

Commands can also be run directly, without opening a shell:

# artisan
$ docker exec containername php artisan env

# composer
$ docker exec containername composer info

A few helper scripts have been added to the image:

# `october` invokes `php artisan october:"$@"`
$ docker exec containername october up

# `artisan` invokes `php artisan "$@"`
$ docker exec containername artisan plugin:install aspendigital.resizer

# `tinker` invokes `php artisan tinker`. Requires `-it` for an interactive shell
$ docker exec -it containername tinker

App Environment

By default, APP_ENV is set to docker.

On image build, a default .env is created and config files for the docker app environment are copied to /var/www/html/config/docker. Environment variables can be used to override the included default settings via docker run or docker-compose.

Note: October CMS settings stored in a site's database override the config. Active theme, mail configuration, and other settings which are saved in the database will ultimately override configuration values.

PHP configuration

Recommended settings for opcache and PHP are applied on image build.

Values set in docker-oc-php.ini can be overridden by passing one of the supported PHP environment variables defined below.

To customize the PHP configuration further, add or replace .ini files found in /usr/local/etc/php/conf.d/.

Environment Variables

Environment variables can be passed to both docker-compose and October CMS.

Database credentials and other sensitive information should not be committed to the repository. Those required settings should be outlined in .env.example

Passing environment variables via Docker can be problematic in production. A phpinfo() call may leak secrets by outputting environment variables. Consider mounting a .env volume or copying it to the container directly.

Docker Entrypoint

The following variables trigger actions run by the entrypoint script at runtime.

Variable Default Action
ENABLE_CRON false true starts a cron process within the container
FWD_REMOTE_IP false true enables remote IP forwarding from proxy (Apache)
