The docker images defined in this repository serve as a starting point for Winter CMS projects.

Based on official docker PHP images, images include dependencies required by Winter, Composer and install the latest release.


Supported Versions

PHP7.4 PHP8.0 PHP8.1 PHP8.2 Apache FPM

WinterCMS WinterCMS WinterCMS WinterCMS WinterCMS WinterCMS WinterCMS WinterCMS

Supported Tags

Tags are combinations of PHP version, web server, and Winter CMS build. The latest tag is the most recent release of Winter CMS on the most recent PHP version and with Apache.

The following tags are examples:

Winter CMS Build PHP Version Web Server Tag
1.2.4 8.2 Apache 8.2-apache-v1.2.4, latest
1.2.3 8.0 FPM 8.0-fpm-v1.2.3

Quick Start

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

$ docker run -p 8080:80 --name winter ghcr.io/mpo-web-consulting/wintercms:latest
# `CTRL-C` to stop
$ docker rm winter  # Destroys the container
  • Visit http://localhost:8080 using your browser.
  • Login to the backend with the username admin
  • The password for admin is generated on first load and printed into the container logs.
  • 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:

Kubernetes

There are some example templates in the kubernetes directory. Change the secrets and ingress files to support your environment requirements. Make sure to install cert-manager to generate ssl certificates for secure ingress.

# start winter using kubernetes templates
kubectl apply -f kubernetes/
# to update deployment
kubectl apply -f kubernetes/
# to remove from cluster
kubectl delete -f kubernetes/

Note: The kubernetes templates were tested in a Microk8s kubernetes cluster with default (hostpath) storage class. Depending on your cluster this will need to be changed in the storage template files.


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 Winter 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 [email protected]:wintercms/wn-user-plugin.git
$ cd wn-user-plugin
$ docker run -p 8080:80 --rm \
  -v $(pwd):/var/www/html/plugins/winter/user \
  ghcr.io/mpo-web-consulting/wintercms: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: ghcr.io/mpo-web-consulting/wintercms
    ports:
      - 8080:80
    volumes:
      - $PWD:/var/www/html/plugins/winter/user

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 \
  ghcr.io/mpo-web-consulting/wintercms php artisan winter:up

# Now run with the volume mounted to your host
$ docker run -p 8080:80 --name winter \
 -v $(pwd)/storage/database.sqlite:/var/www/html/storage/database.sqlite \
 ghcr.io/mpo-web-consulting/wintercms

MySQL / Postgres

Alternatively, you can host the database using another container:

#docker-compose.yml
version: '2.2'
services:
  web:
    image: ghcr.io/mpo-web-consulting/wintercms:latest
    ports:
      - 8080:80
    environment:
      - DB_TYPE=mysql
      - DB_HOST=mariadb #DB_HOST should match the service name of the database container
      - DB_DATABASE=wintercms
      - DB_USERNAME=root
      - DB_PASSWORD=root

  mariadb:
    image: mariadb:10.4
    command: --default-authentication-plugin=mysql_native_password
    ports:
      - 3306:3306
    environment:
      - MYSQL_ROOT_PASSWORD=root
      - MYSQL_DATABASE=wintercms

Provision a new database with winter:up:

docker-compose up -d
docker-compose exec web php artisan winter:up

Cron

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

docker run -p 8080:80 -e ENABLE_CRON=true ghcr.io/mpo-web-consulting/wintercms:latest

Separate the cron process into it's own container:

#docker-compose.yml
version: '2.2'
services:
  web:
    image: ghcr.io/mpo-web-consulting/wintercms:latest
    init: true
    restart: always
    ports:
      - 8080:80
    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: ghcr.io/mpo-web-consulting/wintercms:latest
    init: true
    restart: always
    command: [cron, -f]
    environment:
      - TZ=America/Denver
    volumes_from:
      - web

Self Signed Certificates

Sometimes encyption is useful for testing. Self signed certs can be added by extending the image in another dockerfile:

# Dockerfile for apache with self signed certificates

FROM ghcr.io/mpo-web-consulting/wintercms:develop-php8.0-apache

RUN apt-get update && \
    apt-get install -y --no-install-recommends \
    ssl-cert && \
    rm -rf /var/lib/apt/lists/*

RUN a2enmod ssl; \
    a2ensite default-ssl;

EXPOSE 443

CMD ["apache2-foreground"]

From a docker compose file build with:

version: '2.2'
services:
  web:
    build: <Dockerfile> # Dockerfile should match file defined in example above
    ports:
      - 8080:80
      - 8443:443
    environment:
      - DB_TYPE=mysql
      - DB_HOST=mariadb #DB_HOST should match the service name of the database container
      - DB_DATABASE=wintercms
      - DB_USERNAME=root
      - DB_PASSWORD=root
    volumes:
      # ssl certs could also be volume mapped from elsewhere
      # - .certs/cert.pem:/etc/ssl/certs/ssl-cert-snakeoil.pem:ro
      # - .certs/key.key:/etc/ssl/private/ssl-cert-snakeoil.key:ro

  mariadb:
    image: mariadb:10.4
    command: --default-authentication-plugin=mysql_native_password
    environment:
      - MYSQL_DATABASE=wintercms
      - MYSQL_ROOT_PASSWORD=root

Command Line Tasks

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

docker run -p 8080:80 --name containername -d ghcr.io/mpo-web-consulting/wintercms: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:

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

# `artisan` invokes `php artisan "$@"`
$ docker exec containername artisan plugin:install winter.user

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

Note: There are other examples with different environment variables set up in the examples and test directories.


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: Winter 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-wn-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 Winter 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)
INIT_WINTER false true runs winter up on container start
CMS_ADMIN_PASSWORD Sets CMS admin password if INIT_WINTER true
COMPOSER_UPDATE false true runs composer update in the base laravel directory to update winter and plugins (with persistent storage this will only run once)
INIT_PLUGINS_VENDOR_FOLDERS false true runs composer install in plugins folders where no 'vendor' folder exists. force runs composer install regardless. Helpful when using git submodules for plugins.
PHP_DISPLAY_ERRORS off Override value for display_errors in docker-wn-php.ini
PHP_MEMORY_LIMIT 128M Override value for memory_limit in docker-wn-php.ini
PHP_POST_MAX_SIZE 32M Override value for post_max_size in docker-wn-php.ini
PHP_UPLOAD_MAX_FILESIZE 32M Override value for upload_max_filesize in docker-wn-php.ini
VERSION_INFO false true outputs container current commit, php version, and dependency info on start
