MySQL, the most popular Open Source SQL database management system, is developed, distributed, and supported by Oracle Corporation. MySQL is a database management system. MySQL databases are relational. MySQL software is Open Source. The MySQL Database Server is very fast, reliable, scalable, and easy to use. MySQL Server works in client/server or embedded systems. A large amount of contributed MySQL software is available. – by dev.mysql.com
In Today’s world, most of the applications are depends on the databases. If you don’t want to setup a dedicated database server for your applications, then definitely you might go to the containerized platform.
For small and medium scale industries, running MySQL as a docker container is very specialized platform without spending money for any hardware based servers.
Before running MySQL as a docker container, the docker must be installed on your machine. If you want to know How to install Docker? Please refer the below link.
pull mysql docker image
First step is, we need to pull the MySQL docker image from the docker hub repository. Execute the below command to pull the latest MySQL docker image from the docker hub repository.
docker pull mysql/mysql-server:latest
docker pull mysql/mysql-server:latestlatest: Pulling from mysql/mysql-server ad18637d63f5: Pull complete 3f16d3b57d84: Pull complete e07cad553c93: Pull complete 98363e47b5bd: Pull complete Digest: sha256:f9ab5082218fc9128f00f83bc707886b65b8cdfa4b9809315d18c9140655db2f Status: Downloaded newer image for mysql/mysql-server:latest docker.io/mysql/mysql-server:latest
view docker image
Execute the below command, to view the list of docker images and to make sure the MySQL docker image has been downloaded or not.
docker imagesREPOSITORY TAG IMAGE ID CREATED SIZE mysql/mysql-server latest 12a8d88596c0 8 days ago 294MB
run the mysql docker image as a container
Execute the below command to run the MySQL docker image as a container.
docker run -p 3306:3306 -d --name=mysql mysql/mysql-server:latest
docker run -p 3307:3307 -d --name=mysql mysql/mysql-server:latestde3bad95ad41de45e43f46da8faee8d6aaf6bb64bb099f6f9f8e62aee29bf073root@instance-1:~#
-p 3306: 3306 – represents exposing the MySQL port number
–name=mysql – represents the name of the container
mysql/mysql-server:latest – represents the name of the MySQL docker image
view mysql docker logs
After run the MySQL image as docker container, execute the below command to view logs and get the default “root” user password to login into the MySQL database.
docker logs mysql
mysql – name of the docker container
You can see the following logs on the console with default “root” user password. Copy the password and keep it safe to login into the database.

The docker exec command allows us to run the commands inside the docker container.
docker exec -it mysql bash
Then, execute the below command to login into the MySQL database.
mysql -uroot -p
Console will ask you the password, provide the default root user password took it from the container logs.
mysql -uroot -pEnter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 16Server version: 8.0.17Copyright (c) 2000, 2019, Oracle and/or its affiliates.

Now, execute the SQL commands to access the MySQL database as a Docker container.
alter root user password
Execute the below command to alter the root user password.
ALTER USER 'root'@'localhost' IDENTIFIED BY '
Then, execute the below command to view the list of databases.
