Quickly deploy MySQL and Adminer with Docker Compose

Introduce

• MySQL: MySQL is an open-source relational database management system (RDBMS). Many web applications widely use it, and it forms a central component of the LAMP (Linux, Apache, MySQL, PHP/Python/Perl) and MERN (MongoDB, Express.js, React, Node.js) stacks
• Adminer: Adminer is a lightweight and user-friendly database management tool written in PHP. It allows you to manage MySQL, PostgreSQL, SQLite, MS SQL, and Oracle databases through a web-based interface.
• Docker: Docker is a platform for developing, shipping, and running applications in containers. Containers are lightweight, portable, and self-sufficient, encapsulating everything needed to run an application, including the code, runtime, libraries, and dependencies.
• Docker Compose: Docker Compose is a tool for defining and running multi-container Docker applications. It allows you to define a multi-container environment in a single file, making it easier to manage and deploy complex applications.
• In this blog, we will discuss how to deploy MySQL and Adminer with Docker Compose

Preparation

To get started, the initial step is to install Docker and Docker Compose. Detailed instructions can be found in this link. Once this installation is complete, you’re ready to dive into the powerful features that Docker brings to the table. Get ready to explore a world of seamless containerization and efficient deployment!

Create a Docker Compose YAML file

Now, prepare yourself and start the process by creating a new folder and navigating to it:

mkdir mysql-compose
cd mysql-compose

Create a new file named docker-compose.yaml and use the following code

version: "3.5"
services:

  mysql:
    image: mysql:8.2.0
    container_name: "mysql"
    command: --default-authentication-plugin=mysql_native_password
    restart: always
    ports:
      - '3306:3306'
    environment:
      MYSQL_ROOT_PASSWORD: "mysql_password"
    volumes:
      - [path-to-store-mysql-data]:/var/lib/mysql

  adminer:
    image: adminer
    restart: always
    ports:
      - 8080:8080

Adjust certain points to suit your specific situation:

• MYSQL_ROOT_PASSWORD
• [path-to-store-mysql-data]

Save the file once you make the adjustments.

Start docker compose

Now, you simply need to run a single-line command to start both MySQL and Adminer:

docker compose up

or

docker compose up -d

to start it as a daemon.

Check the results

Awesome! You can access Adminer using the link http://your-ip-server:8080 to get started.
Let’s attempt to connect to MySQL on port 3306 with user root

Clean up after running Docker Compose

After usage, you can tidy up by running the command

docker compose down

Summary

That is an easy and quick way to deploy MySQL and Adminer with Docker Compose, even if you are a beginner. I hope you will succeed in deploying it. Check out other useful tips on the Toan Thien blog.
