Introduction
This is an article where the main focus is just to run MySQL Database Server using docker container. It is an alternative to be able to run MySQL Database Server without having to install it in the first place. The preparation is simple and fast relying on the available internet connection. The implementation of providing MySQL Database Server’s service is done using a docker container in Linux operating system. Moreover, the implementation is in Linux Ubuntu 19.10. The arrangement of this article is exist in several parts. The process for running MySQL Database Server using Docker Container exist in two parts. The first part is the configuration step. The last one is the testing step to test whether the MySQL Database Server is running in the docker container and it exist for further access.
Configuration Step
This part is a part for the configuration step of the docker container. In order to run MySQL Database Server, just perform the following sequence of actions :
1. Create a file with the name of docker-compose.yml. Just place the file in any folder or path exist in the operating system. In this article, for an example the file exist in ‘/home/user/docker-compose/0-db’.
2. Fill the content of the file ‘docker-compose.yml’ with the following configuration :
version: '2'
services:
db:
image: mysql
volumes:
- "./data/db:/var/lib/mysql"
environment:
MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}
MYSQL_DATABASE: ${MYSQL_DATABASE}
MYSQL_USER: ${MYSQL_USER}
MYSQL_PASSWORD: ${MYSQL_PASSWORD}
3. Create another file with the name of ‘.env’. This file will be useful to define the value of the environment variables needed in the ‘docker-compose.yml’ file. Modify and adjust the value of the environment variables accordingly as follow :
MYSQL_ROOT_PASSWORD=password MYSQL_DATABASE=mysql MYSQL_USER=root MYSQL_PASSWORD=password
Before running the docker container, first of all list all of the available container by executing the following command :
sudo docker container ls -a
The execution of the above command exist in the following output :

4. After finishing the above step for creating the necessary files and also checking for the running docker container, execute the following command in the command line interface using sudo command as a normal user or just simply as root :
sudo docker-compose up -d
The output of the above command execution exist as follows :
user@hostname:~/docker-compose/0-db$ sudo docker-compose up -d Pulling db (mysql:)... latest: Pulling from library/mysql 619014d83c02: Pull complete 9ced578c3a5f: Pull complete 731f6e13d8ea: Pull complete 3c183de42679: Pull complete 6de69b5c2f3c: Pull complete 00f0a4086406: Pull complete 84d93aea836d: Pull complete f18efbfd8d76: Pull complete 012b302865d1: Pull complete fe16fd240f59: Pull complete ca3e793e545e: Pull complete 51d0f2cb2610: Pull complete Creating 0-db_db_1 ... Pulling db (mysql:)... Creating 0-db_db_1 ... done user@hostname:~/docker-compose/0-db$
Try to execute the previous command again to see whether there is a running container created after the execution of the above command as follows :
user@hostname:~/docker-compose/0-db$ sudo docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 6a051f794447 mysql "docker-entrypoint.s…" About a minute ago Up About a minute 3306/tcp, 33060/tcp 0-db_db_1 4b477836bff1 mysql/mysql-server:5.7 "/entrypoint.sh mysq…" 3 weeks ago Exited (255) 3 weeks ago 33060/tcp, 0.0.0.0:3308->3306/tcp determined_euclid 4cb95b4f1ea4 mysql/mysql-server:5.7 "/entrypoint.sh mysq…" 5 weeks ago Exited (255) 5 weeks ago 3306/tcp, 33060/tcp laughing_noyce 167795afbce0 mysql/mysql-server:5.7 "/entrypoint.sh mysq…" 5 weeks ago Exited (0) 5 weeks ago epic_kilby e4a9ee25671b mysql/mysql-server:5.7 "/entrypoint.sh mysq…" 6 weeks ago Exited (255) 5 weeks ago 33060/tcp, 0.0.0.0:3308->3306/tcp hopeful_wescoff 10f7d4bdb1dd mysql/mysql-server:5.7 "/entrypoint.sh mysq…" 7 weeks ago Exited (255) 6 weeks ago 33060/tcp, 0.0.0.0:3308->3306/tcp adoring_elion 6a5e88f9a264 mysql/mysql-server:5.7 "/entrypoint.sh mysq…" 7 weeks ago Created vigiant_shtern 972d07bfe2a1 mysql/mysql-server:5.7 "/entrypoint.sh mysq…" 7 weeks ago Exited (255) 7 weeks ago 33060/tcp, 0.0.0.0:3308->3306/tcp vigilant_shtern 42c98cb79a53 mysql/mysql-server:5.7 "/entrypoint.sh mysq…" 7 weeks ago Exited (0) 7 weeks ago distracted_feynman ecd2b654b683 mysql/mysql-server:5.7 "/entrypoint.sh mysq…" 7 weeks ago Created 33060/tcp, 0.0.0.0:3308->3306/tcp eloquent_lovelace 267808afe834 mysql/mysql-server:5.7 "/entrypoint.sh mysq…" 7 weeks ago Exited (255) 7 weeks ago 33060/tcp, 0.0.0.0:3308->3306/tcp mysql_local user@hostname:~/docker-compose/0-db$
Testing Step
In the last part, it is just the part for testing the running MySQL Database Server exist in the docker container. According to the above output command execution in the previous part, there is a new container running with the name of ‘mysql’. So, in order to test the functionality of the running MySQL Datase Server, try to access it. Before trying to access it, execute the following following command to check the IP Address of the running container :
docker inspect container_id | grep IPAddresss
The following is the output of the above command execution using part of the container ID of ‘6a051f794447’ representing for the MySQL Database running container :
user@hostname:~/docker-compose/0-db$ sudo docker inspect 6a05 | grep IPAddress
"SecondaryIPAddresses": null,
"IPAddress": "",
"IPAddress": "172.20.0.2",
user@hostname:~/docker-compose/0-db$
The following is the execution of the command for accessing or connecting to MySQL Database Server :
root@hostname:/home/user/docker-compose/0-db# mysql -uroot -p -P3306 -h172.20.0.2 Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 8 Server version: 8.0.19 MySQL Community Server - GPL Copyright (c) 2000, 2020, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | sys | +--------------------+ 4 rows in set (0.14 sec) mysql> create database mydb; Query OK, 1 row affected (1.42 sec) mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mydb | | mysql | | performance_schema | | sys | +--------------------+ 5 rows in set (0.00 sec) mysql>
Apparently, as it exists in the above output, accessing or connecting to MySQL Database Server is a success.
