How to Install phpMyAdmin on Docker

phpMyAdmin is a popular web-based interface used for managing MySQL databases. Docker, an open-source platform, allows you to automate the deployment of applications inside containers, each providing dependencies needed to run an application. By installing phpMyAdmin on Docker, you can streamline your database administrative tasks efficiently.

Prerequisites

• Basic understanding of Docker and command line interface.
• Access to a system with Docker installed. If not installed, refer to our guide on how to install Docker (Official site).
• Internet connection for downloading Docker images.

Step 1: Set Up Docker Environment

Ensure Docker is installed and running on your system. You can verify this by executing:

docker --version

This command should return the Docker version installed on your system.

Step 2: Pull phpMyAdmin Docker Image

To install phpMyAdmin, first pull the image from Docker Hub using:

docker pull phpmyadmin/phpmyadmin

This command downloads the necessary Docker image.

Step 3: Run phpMyAdmin Container

To launch phpMyAdmin, use the following command:

docker run --name myphpadmin -d --link mysql_db:db -p 8080:80 phpmyadmin/phpmyadmin

In this command:

• --name myphpadmin names the container myphpadmin.
• --link mysql_db:db connects phpMyAdmin with an existing MySQL container named mysql_db.
• -p 8080:80 maps port 80 to port 8080 on the local machine.

Step 4: Access phpMyAdmin

Once the container is running, open a web browser and navigate to http://localhost:8080. You should see the phpMyAdmin login page, enabling you to manage your databases.

Troubleshooting

If phpMyAdmin doesn’t start, ensure no port conflicts by checking if port 8080 is free or modify the -p flag to another port. Verify your MySQL container is also running properly.

Summary Checklist

• Verify Docker is installed and running.
• Pull the phpMyAdmin Docker image.
• Create and run the phpMyAdmin Docker container.
• Access phpMyAdmin via the web browser.
• Troubleshoot any issues that arise with port allocation or container linkage.

By following these steps, you can efficiently manage your MySQL databases through phpMyAdmin on a Docker container.
