Official phpMyAdmin Docker image

Run phpMyAdmin with Alpine and PHP built in web server.

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

Credentials

phpMyAdmin does use MySQL server credential, please check the corresponding server image for information how it is setup.

The official MySQL and MariaDB use 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.

Usage with linked server

First you need to run MySQL or MariaDB server in Docker, and this image need link a running mysql instance container:

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

Usage with external server

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

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

Usage with arbitrary server

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

docker run --name myadmin -d --link mysql_db_server:db -p 8080:80 -e PMA_ARBITRARY=1 phpmyadmin/phpmyadmin

Usage with docker-compose and arbitrary server

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

Using the docker-compose.yml from https://github.com/phpmyadmin/docker

docker-compose up -d

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:/config.user.inc.php

On the "docker run" line like this:

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

See the following links for config file information. http://docs.phpmyadmin.net/en/latest/config.html#config http://docs.phpmyadmin.net/en/latest/setup.html

Usage behind reverse proxys

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

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_PORT - define port of the MySQL server
PMA_HOSTS - define comma separated list of address/host names of the MySQL servers
PMA_USER and PMA_PASSWORD - define username to use for config authentication method
