CMS in Docker on a Raspberry Pi

Two steps to run a LAMP system on a Raspberry Pi:

1. Create a Dockerfile for the webserver with PHP. Add all PHP plugins etc. which are necessary. In the example, MySQL extensions are added
2. A Docker Compose file fires up the webserver image and a MySQL image. The one which is used in the example (“jsurf/rpi-mariadb:latest”) is a special MySQL image for the Raspberry architecture.

The Dockerfile:

FROM php:7.4-apache
RUN docker-php-ext-install mysqli pdo pdo_mysql
RUN docker-php-ext-enable mysqli

The Docker Composefile:

version: "3"
services:
  mariadb:
    image: jsurf/rpi-mariadb:latest
    environment:
      - "MYSQL_ROOT_PASSWORD=pwd"
    volumes:
      - /home/pi/apache/mysql/:/var/lib/mysql
    ports:
      - 3306:3306
    expose:
      - 3306

  apache:
    image: tom/webserver:2
    volumes:
      - /home/pi/apache/data:/var/www/html
    expose:
      - 80
    ports:
      - 80:80
