Structure

First, Define required attributes.

services:
  mysql:
    image: mysql:8.0.39
    environment:
      MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}

• As image, we specify MySQL Docker Official Image.
  If the version of MySQL is specified as latest, the image will be created based on the latest version.
  The latest version as of this writing is 9.0.1.
  The reason for specifying version 8.0.39 is that it is the most recent version compatible with MySQL Workbench.

• As environment, we set the root user password.
  The root user is automatically created when MySQL is installed.
  The list of environment variables that can be specified is written in docker hub.

Next, Mapping ports.

services:
  mysql:
    image: mysql:8.0.39
    environment:
      MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}
    # new attribute.
    ports:
      - "${MYSQL_HOST_PORT}:3306"

• 3306 is the default port number for MySQL to listen on for TCP/IP.

• This port is used by MySQL Workbench to connect to the container.

Finally, Make DB data persistent.

services:
  mysql:
    image: mysql:8.0.39
    environment:
      MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}
    ports:
      - "${MYSQL_HOST_PORT}:3306"
    # new attribute.
    volumes:
      - db-data:/var/lib/mysql

# new element.
volumes:
  db-data:

• Create persistent data stores by defining volumes element.
  In this case, we create the volume named db-data.

• The default data-dir for MySQL is /var/lib/mysql and we mount it to the volume.

.env

MYSQL_HOST_PORT={host-port}
MYSQL_ROOT_PASSWORD={root-user-password}

Docker

Create Container, Image, and Volume.

1. Open the terminal.

2. Move the current-dir to the location where docker-compose.yml is located.

3. Execute docker compose create.
   

   docker compose create
   

Check the Version of MySQL.

1. Start the container.
   

   docker compose start
   

2. Check the name of the container.
   

   docker ps
   

   The Names column corresponds to it.

3. Check the version in the container.
   

   docker exec <container-name> mysql -V
   

   For example, the following response is returned.
   

   mysql  Ver 8.0.39 for Linux on aarch64 (MySQL Community Server - GPL)
   

4. Stop the container.
   

   docker compose stop
   

MySQL Workbench

Download.

1. Download. The version to be downloaded is 8.0.38. The M1 chip uses the ARM architecture, so the appropriate one is macOS (ARM, 64-bit), DMG Archive.

Add Connection.

1. Start the container to connect to MySQL.
   

   docker compose start
   

2. Open it and Click the PLUS button.
   

3. The following dialog opens.
   

   Enter any value for Connection Name, and update Port with .env.MYSQL_HOST_PORT.

4. Click the Test Connection button.
   After entering .env.MYSQL_ROOT_PASSWORD, a connection test will be conducted.
   If successful, click the OK button to close this dialog.

5. Stop the container.
   

   docker compose stop
   

Operate.

1. Start the container.
   

   docker compose start
   

2. Click the connection.
   

3. Enter .env.MYSQL_ROOT_PASSWORD if not saved in keychain.

4. Operate until satisfied.
   

5. Stop the container.
   

   docker compose stop
