Official phpMyAdmin Docker image

Note that since phpMyAdmin has been accepted in to the official DockerHub repository, you can use either that or this older phpMyAdmin repository for your Docker installation. This is maintained as a courtesy to users who have not migrated.

Run phpMyAdmin with Alpine, Apache and PHP FPM.

All of the following examples will bring you phpMyAdmin on http://localhost:8080 where you can enjoy your happy MySQL administration.

Credentials

phpMyAdmin connects using your MySQL server credentials. Please check your corresponding database server image for information on the default username and password or how to specify your own custom credentials during installation.

The official MySQL and MariaDB images use the following environment variables to define these:

  • MYSQL_ROOT_PASSWORD - This variable is mandatory and specifies the password that will be set for the root superuser account.
  • MYSQL_USER, MYSQL_PASSWORD - These variables are optional, used in conjunction to create a new user and to set that user's password.

Supported Docker Hub tags

The following tags are available:

  • latest, fpm, and fpm-alpine are always the most recent released version
  • Major versions, such as 5, 5-fpm, and 5-fpm-alpine
  • Specific minor versions, such as 5.0, 5.0-fpm, and 5-fpm-alpine
  • Specific patch versions, such as 5.0.0, 5.0.0-fpm, and 5.0.0-fpm-alpine. Note that, on rare occasion, there may be an intermediary "docker-only" release, such as 4.9.2-1

A complete list of tags is available at Docker Hub

Image variants

We provide three variations:

  • "apache" includes a full Apache webserver with PHP and includes everything needed to work out of the box. This is the default when only a version number is requested.
  • "fpm" only starts a PHP FPM container. Use this variant if you already have a separate webserver. This includes more tools and is therefore a larger image than the "fpm-alpine" variation.
  • "fpm-alpine" has a very small footprint. It is based on Alpine Linux and only starts a PHP FPM process. Use this variant if you already have a separate webserver. If you need more tools that are not available on Alpine Linux, use the fpm image instead.

Usage with linked server

First you need to run a MySQL or MariaDB server in Docker, and the phpMyAdmin image needs to be linked to the running database container:

docker run --name phpmyadmin -d --link mysql_db_server:db -p 8080:80 phpmyadmin:latest

Usage with external server

You can specify a MySQL host in the PMA_HOST environment variable. You can also use PMA_PORT to specify the port of the server in case it's not the default one:

docker run --name phpmyadmin -d -e PMA_HOST=dbhost -p 8080:80 phpmyadmin:latest

Usage with arbitrary server

You can use arbitrary servers by adding the environment variable PMA_ARBITRARY=1 to the startup command:

docker run --name phpmyadmin -d -e PMA_ARBITRARY=1 -p 8080:80 phpmyadmin:latest

Usage with docker-compose and arbitrary server

This will run phpMyAdmin with the arbitrary server option - allowing you to specify any MySQL/MariaDB server on the login page.

version: '3.1'

services:
  db:
    image: mariadb:10.11
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: notSecureChangeMe

  phpmyadmin:
    image: phpmyadmin
    restart: always
    ports:
      - 8080:80
    environment:
      - PMA_ARBITRARY=1

Adding Custom Configuration

You can add your own custom config.inc.php settings (such as Configuration Storage setup) by creating a file named config.user.inc.php with the various user defined settings in it, and then linking it into the container using:

-v /some/local/directory/config.user.inc.php:/etc/phpmyadmin/config.user.inc.php

On the docker run line like this:

docker run --name phpmyadmin -d --link mysql_db_server:db -p 8080:80 -v /some/local/directory/config.user.inc.php:/etc/phpmyadmin/config.user.inc.php phpmyadmin:latest

Be sure to have <?php as your first line of the configuration file or the contents will not be detected as PHP code.

Example:

<?php

$cfg['ShowPhpInfo'] = true; // Adds a link to phpinfo() on the home page

See the following links for config file information:

Adding custom configuration in /etc/phpmyadmin/conf.d

you can also consider storing your custom configuration files in the folder /etc/phpmyadmin/conf.d, which is very suitable for managing multiple phpMyAdmin configuration files for different hosts,Then you can create server-1.php, server-2.php, or any file name you want, and store them in the conf.d directory mounted on the host.

On the docker run line like this:

docker run --name phpmyadmin -d --link mysql_db_server:db -p 8080:80 -v /some/local/directory/conf.d:/etc/phpmyadmin/conf.d:ro phpmyadmin:latest

Usage behind a reverse proxy

Set the variable PMA_ABSOLUTE_URI to the fully-qualified path (https://pma.example.net/) where the reverse proxy makes phpMyAdmin available.

Sessions persistence

In order to keep your sessions active between container updates you will need to mount the /sessions folder.

-v /some/local/directory/sessions:/sessions:rw

Environment variables summary

  • PMA_ARBITRARY - when set to 1 connection to the arbitrary server will be allowed
  • PMA_HOST - define address/host name of the MySQL server
  • PMA_VERBOSE - define verbose name of the MySQL server
  • PMA_PORT - define port of the MySQL server
