🏔️ Artisanal Docker images with Alpine Linux

Docker Pulls Docker Image Size (latest by date)

A set of lightweight Docker images created with Laravel in mind, but work just as fine for other applications. At the basis lies Alpine Linux and the amazing Docker-Webstack which keeps the images that you pull in very small but usable.

The image sets you up with Alpine Linux, PHP-FPM, Nginx. Currently there is an image for different PHP versions available.

Installation

In the folder of your application create two files: docker-compose.yml and Dockerfile (note that the latter has no extension). On the command line, run docker compose up -d --build and view your containerized application at localhost:80.

The docker image contains a healthcheck. You can run the command docker-compose ps to see if the build was succesful, the state should mention "Up (healthy)" for the app container.

Docker-compose.yml

services:
  app:
    build: .
    ports:
      - 80:80
    volumes:
      - .:/www:delegated

Dockerfile

FROM jeroeng/alpine-artisan:web8.3

Configuration

In the end, the best Docker setup is one you create yourself. That being said, this is how you could quickly build upon the Docker image from this repository.

Using a database

Percona is an (optimized) version of MySQL and very useful as your database server. Add the following to your docker-compose.yml file:

services:
  # app container definition

  db:
    image: percona:5.7
      environment:
        MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD:-secret}
        MYSQL_DATABASE: my_database
        MYSQL_USER: jeroen
        MYSQL_PASSWORD: ${MYSQL_ROOT_PASSWORD:-secret}
      volumes:
        - mysql-data:/var/lib/mysql:rw
      ports:
        - 3306:3306
volumes:
  mysql-data: # nothing necessary here, let Docker manage the storage

Your application's .env should contain the following environment variables, after that run docker compose up -d --build again to have a database container running next to your app.

DB_CONNECTION=mysql
DB_HOST=database
DB_PORT=3306
DB_DATABASE=my_database
DB_USERNAME=jeroen
DB_PASSWORD=secret

Using Redis

A typical use of redis is for queues (possibly in combination with Laravel Horizon). To have a redis container, add to the docker-compose.yml file:

services:
  # app container definition

  queue:
      image: redis:5-alpine
      ports:
        - 6379:6379

Adapt your .env file as well, and after another docker compose up -d --build you will have a redis container running for your application (yes, there is no password in this case). If you want to use Horizon, you would still need to install it in your application.

QUEUE_CONNECTION=redis
REDIS_HOST=queue
REDIS_PASSWORD=
REDIS_PORT=6379

Standalone Laravel Horizon

Laravel Horizon requires a daemon in order to work. If you want to have Laravel Horizon running continuously you may start a new container based on the app one. The image name, test_app is unique for your application, test is the name of the folder, app is the name of the app container. After a docker-compose build this image name should be listed when you run docker images.

services:
  horizon:
    image: test_app
    command: php artisan horizon

Note: this only runs horizon locally using docker-compose. As soon as you want to host horizon in a container in the cloud, e.g. using kubernetes, you will have to build a separate image.

Contributing

Clone this repository and run make to see which commands are there to help you. every command requires a TAG= parameter, which is the Docker image you want to build, for example: make build TAG=web8.0.
