Docker - Nginx + PHP FPM + MariaDB + PhpMyAdmin

ReadMe.md

Docker

This is a docker-compose template for a lemp stack.

Make sure to change both the root password under the mysql service, and the absolute URI on the phpmyadmin container.
You can also expose phpMyAdmin locally instead of remotely by properly configuring the ports.

Default locations:
(Original) -> (Your server)
/var/www/html -> ./webroot
/etc/nginx -> ./nginx
/etc/nginx/sites-enabled -> ./nginx/sites-enabled
/var/lib/mysql -> ./mariadb (MariaDB Disk Storage)
/sessions -> ./phpmyadmin/sessions (phpMyAdmin session storage)

Don't forget! -> To use phpMyAdmin behind the nginx container, you need to configure a proxy-pass entry on it.

nginx proxy_pass example:

server {
        listen 80;
        listen [::]:80;
        listen 443 ssl;
        listen [::]:443 ssl;
        server_name phpmyadmin.your.domain;
        location / {
                proxy_set_header    Host $host;
                proxy_set_header    X-Real-IP $remote_addr;
                proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header    X-Forwarded-Proto $scheme;
                proxy_pass          http://phpmyadmin/; #! phpmyadmin is the docker host !
                proxy_read_timeout  90;
        }
}

docker-compose.yml

version: '3.2'
services:
  nginx:
    image: richarvey/nginx-php-fpm:latest
    container_name: nginx
    restart: always
    ports:
     - "80:80"
    volumes:
     - "./nginx/:/etc/nginx"
     - "./webroot/:/var/www/html"
    external_links:
     - mariadb:mariadb
     - phpmyadmin:phpmyadmin
  mariadb:
    image: mariadb
    container_name: mariadb
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: your_sql_root_password
    volumes:
     - "./mariadb/:/var/lib/mysql"
  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    container_name: phpMyAdmin
    restart: always
    environment:
     - "PMA_HOST=mariadb"
     - "PMA_PORT=3306"
     - "PMA_ABSOLUTE_URI=https://phpmyadmin.your.domain"
    external_links:
     - mariadb:mariadb
    volumes:
     - "./phpmyadmin/sessions:/sessions"

why not use the fpm version or fpm-alpine instead of apache webserver phpmyadmin?
