Docker Container: Accessing Host MySQL
Docker has revolutionized the way applications are developed and deployed. It provides a platform-independent containerization environment that can help developers to build, package, and distribute their applications easily. One of the challenges that developers face is accessing the host’s MySQL database from a Docker container. In this article, we will explore how to access the host’s MySQL database from a Docker container.
Prerequisites To follow along with this article, you will need:
- Docker installed on your machine
- A MySQL server running on your host machine
- Basic knowledge of Docker and MySQL
Connecting to Host’s MySQL from Docker Container To connect to the host’s MySQL server from a Docker container, we need to follow these steps:
Step 1: Make sure your docker container is on the network bridge with the host. you can check it through this guide https://stackoverflow.com/questions/43904562/docker-how-to-find-the-network-my-container-is-in.
Step 2: Log in to MySQL as ROOT on the host.
Step 3: Use mysql database and select * from user to show all users.
Here in the Host column, change localhost to%.
If safer if you create another user and database and access it.
Step 4: If still not working, open bind address mysql to accept from all connection.
edit here /etc/mysql/mysql.conf.d/mysqld.cnf and change bind-address to 0.0.0.0
Conclusion In this article, we have seen how to access the host’s MySQL database from a Docker container. By following the steps outlined above, you can connect to your host’s MySQL server and perform any necessary operations. Docker provides a powerful platform for developing and deploying applications, and being able to access the host’s MySQL database from within a container is an essential feature that can simplify development and deployment workflows.
