How to Set Up MySQL Database with Docker (2024)

How to Set Up MySQL Database with Docker (Using Docker Command and Docker-Compose) Setting up a MySQL database using Docker simplifies the process of database management, allowing you to create, configure, and manage your databases in isolated containers. This guide will walk you through the steps to set up a MySQL database using Docker commands and Docker-Compose. *Requirements:* Docker installed on your system Basic knowledge of command-line interface *Step-by-Step Guide:* Using Docker Command Step 1: Pull the MySQL Docker Image First, you need to pull the official MySQL image from the Docker Hub repository. ```bash docker pull mysql:latest ``` Step 2: Run a MySQL Container Run a container using the MySQL image with environment variables for the root password and other configurations. ```bash docker run --name mysql-container -e MYSQL_ROOT_PASSWORD=rootpassword -e MYSQL_DATABASE=mydatabase -e MYSQL_USER=myuser -e MYSQL_PASSWORD=mypassword -p 3306:3306 -d mysql:latest ``` `--name mysql-container`: Names the container `mysql-container`. `-e MYSQL_ROOT_PASSWORD=rootpassword`: Sets the root password. `-e MYSQL_DATABASE=mydatabase`: Creates a database named `mydatabase`. `-e MYSQL_USER=myuser`: Creates a user named `myuser`. `-e MYSQL_PASSWORD=mypassword`: Sets the password for `myuser`. `-p 3306:3306`: Maps port 3306 of the container to port 3306 of the host. `-d`: Runs the container in detached mode. `mysql:latest`: Uses the latest MySQL image. Step 3: Verify the MySQL Container Check if the MySQL container is running. ```bash docker ps ``` You should see your `mysql-container` listed and running. Step 4: Connect to the MySQL Database You can now connect to the MySQL database using the MySQL client or any other database management tool. ```bash docker exec -it mysql-container mysql -u root -p ``` Enter the root password when prompted. Using Docker-Compose Step 1: Create a Docker-Compose File Create a `docker-compose.yml` file in your project directory. ```yaml version: '3.1' services: db: image: mysql:latest container_name: mysql-compose-container environment: MYSQL_ROOT_PASSWORD: rootpassword MYSQL_DATABASE: mydatabase MYSQL_USER: myuser MYSQL_PASSWORD: mypassword ports: "3306:3306" volumes: db_data:/var/lib/mysql volumes: db_data: ``` Step 2: Run Docker-Compose Navigate to the directory containing the `docker-compose.yml` file and run: ```bash docker-compose up -d ``` `up`: Creates and starts the containers. `-d`: Runs the containers in detached mode. Step 3: Verify the MySQL Container Check if the MySQL container is running using: ```bash docker-compose ps ``` Step 4: Connect to the MySQL Database Similar to the Docker command method, connect to the MySQL database using the MySQL client: ```bash docker-compose exec db mysql -u root -p ``` Enter the root password when prompted. *Conclusion:* By following these steps, you have successfully set up a MySQL database using Docker commands and Docker-Compose. This setup allows for easy deployment and management of your MySQL databases in isolated containers, making your development and testing processes more efficient.
