What is phpMyAdmin?

phpMyAdmin is a free software tool written in PHP, intended to handle the administration of MySQL over the Web. phpMyAdmin supports a wide range of operations on MySQL and MariaDB. Frequently used operations (managing databases, tables, columns, relations, indexes, users, permissions, etc) can be performed via the user interface, while you still have the ability to directly execute any SQL statement.

TL;DR

Docker Compose

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-phpmyadmin/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

You can find the default credentials and available configuration options in the Environment Variables section.

Why use Bitnami Images?

  • Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
  • With Bitnami images the latest bug fixes and features are available as soon as possible.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
  • All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading Linux distribution.
  • All Bitnami images available in Docker Hub are signed with Docker Content Trust (DCT). You can use DOCKER_CONTENT_TRUST=1 to verify the integrity of the images.
  • Bitnami container images are released daily with the latest distribution packages available.

How to deploy phpMyAdmin in Kubernetes?

Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the Bitnami phpMyAdmin Chart GitHub repository.

Bitnami containers can be used with Kubeapps for deployment and management of Helm Charts in clusters.

Prerequisites

To run this application you need Docker Engine >= 1.10.0. Docker Compose is recommended with a version 1.6.0 or later.

How to use this image

phpMyAdmin requires access to a MySQL database or MariaDB database to work. We'll use our very own MariaDB image.

Using Docker Compose

The main folder of this repository contains a functional docker-compose.yml file. Run the application using it as shown below:

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-phpmyadmin/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

Using the Docker Command Line

If you want to run the application manually instead of using docker-compose, these are the basic steps you need to run:

  1. Create a network
$ docker network create phpmyadmin-tier
  1. Create a volume for MariaDB persistence and create a MariaDB container
$ docker volume create --name mariadb_data
$ docker run -d --name mariadb -e ALLOW_EMPTY_PASSWORD=yes \
  --net phpmyadmin-tier \
  --volume mariadb_data:/bitnami/mariadb \
  bitnami/mariadb:latest
  1. Launch the phpMyAdmin container
$ docker run -d --name phpmyadmin -p 80:8080 -p 443:8443 \
  --net phpmyadmin-tier \
  bitnami/phpmyadmin:latest

Access your application at http://your-ip/

Persisting your application

If you remove the container all your data and configurations will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a volume at the /bitnami path. Additionally you should mount a volume for persistence of the MariaDB data.

The above examples define a Docker volume named mariadb_data. The application state will persist as long as this volume is not removed.

To avoid inadvertent removal of these volumes you can mount host directories as data volumes. Alternatively you can make use of volume plugins to host the volume data.

Mount host directories as data volumes with Docker Compose

This requires a minor change to the docker-compose.yml file present in this repository:

services:
  mariadb:
  ...
    volumes:
      - /path/to/mariadb-persistence:/bitnami/mariadb
  ...

Mount host directories as data volumes using the Docker command line

  1. Create a network (if it does not exist)
$ docker network create phpmyadmin-tier
  1. Create a MariaDB container with host volume
$ docker run -d --name mariadb -e ALLOW_EMPTY_PASSWORD=yes \
  --net phpmyadmin-tier \
  --volume /path/to/mariadb-persistence:/bitnami/mariadb \
  bitnami/mariadb:latest
  1. Launch the phpMyAdmin container
$ docker run -d --name phpmyadmin -p 80:8080 -p 443:8443 \
  --net phpmyadmin-tier \
  bitnami/phpmyadmin:latest

Upgrading phpMyAdmin

Bitnami provides up-to-date versions of MariaDB and phpMyAdmin, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. We will cover here the upgrade of the phpMyAdmin container. For the MariaDB upgrade see https://github.com/bitnami/bitnami-docker-mariadb/blob/master/README.md#upgrade-this-image

The bitnami/phpmyadmin:latest tag always points to the most recent release. To get the most recent release you can simple repull the latest tag from the Docker Hub with docker pull bitnami/phpmyadmin:latest. However it is recommended to use tagged versions.

  1. Get the updated images:
$ docker pull bitnami/phpmyadmin:latest
  1. Stop your container
  • For docker-compose: $ docker-compose stop phpmyadmin
  • For manual execution: $ docker stop phpmyadmin
  1. Remove the currently running container
  • For docker-compose: $ docker-compose rm -v phpmyadmin
  • For manual execution: $ docker rm -v phpmyadmin
  1. Run the new image
  • For docker-compose: $ docker-compose up phpmyadmin
  • For manual execution: docker run --name phpmyadmin bitnami/phpmyadmin:latest

Customize this image

The Bitnami phpMyAdmin Docker image is designed to be extended so it can be used as the base image for your custom web applications.

Extend this image

Before extending this image, please note there are certain configuration settings you can modify using the original image:

If your desired customizations cannot be covered using the methods mentioned above, extend the image. To do so, create your own image using a Dockerfile with the format below:

FROM bitnami/phpmyadmin
## Put your customizations below
...

Here is an example of extending the image with the following modifications:

  • Install the vim editor
  • Modify the Apache configuration file
  • Modify the ports used by Apache
  • Modify the default container user
FROM bitnami/phpmyadmin
LABEL maintainer "Bitnami <containers@bitnami.com>"

## Change user to perform privileged actions
USER 0
## Install 'vim'
RUN install_packages vim
## Revert to the original non-root user
USER 1001

## Enable mod_ratelimit module
RUN sed -i -r 's/#LoadModule ratelimit_module/LoadModule ratelimit_module/' /opt/bitnami/apache/conf/httpd.conf

## Modify the ports used by Apache by default
# It is also possible to change these environment variables at runtime
ENV APACHE_HTTP_PORT_NUMBER=8181
ENV APACHE_HTTPS_PORT_NUMBER=8143
EXPOSE 8181 8143

## Modify the default container user
USER 1002

Based on the extended image, you can use a Docker Compose file like the one below to add other features:

version: '2'
services:
  mariadb:
    image: 'bitnami/mariadb:10.3'
    environment:
      - MARIADB_ROOT_PASSWORD=bitnami
    volumes:
      - 'mariadb_data:/bitnami/mariadb'
  phpmyadmin:
    build: .
    ports:
      - '80:8181'
      - '443:8143'
    depends_on:
      - mariadb
    volumes:
      - 'phpmyadmin_data:/bitnami/mariadb'
volumes:
  mariadb_data:
    driver: local
  phpmyadmin_data:
    driver: local

Notable Changes

5.0.2-debian-10-r73

  • Decrease the size of the container. The configuration logic is now based on Bash scripts in the rootfs/ folder.
  • The PHPMYADMIN_ALLOW_NO_PASSWORD environment variable has been deprecated in favor of DATABASE_ALLOW_NO_PASSWORD.
  • New environment variables have been added to support configuring extra PHP options: PHP_UPLOAD_MAX_FILESIZE for upload_max_filesize, and PHP_POST_MAX_SIZE for post_max_size.

4.8.5-debian-9-r96 and 4.8.5-ol-7-r111

  • This image has been adapted so it's easier to customize. See the Customize this image section for more information.
  • The Apache configuration volume (/bitnami/apache) has been deprecated, and support for this feature will be dropped in the near future. Until then, the container will enable the Apache configuration from that volume if it exists. By default, and if the configuration volume does not exist, the configuration files will be regenerated each time the container is created. Users wanting to apply custom Apache configuration files are advised to mount a volume for the configuration at /opt/bitnami/apache/conf, or mount specific configuration files individually.
  • The PHP configuration volume (/bitnami/php) has been deprecated, and support for this feature will be dropped in the near future. Until then, the container will enable the PHP configuration from that volume if it exists. By default, and if the configuration volume does not exist, the configuration files will be regenerated each time the container is created. Users wanting to apply custom PHP configuration files are advised to mount a volume for the configuration at /opt/bitnami/php/conf, or mount specific configuration files individually.
  • Enabling custom Apache certificates by placing them at /opt/bitnami/apache/certs has been deprecated, and support for this functionality will be dropped in the near future. Users wanting to enable custom certificates are advised to mount their certificate files on top of the preconfigured ones at /certs.
