#Introduction

In this tutorial, How to use Docker deploy MySQL and phpMyAdmin.

Docker is a software platform designed to make it easier to create, deploy, and run applications by using containers.

MySQL Database Service is a fully managed database service to deploy cloud-native applications. Quota from MySQL.

Prerequisites Docker deploy MySQL and phpMyAdmin

• Host OS: Ubuntu 21.04
• Installed Docker

Deploy the MySQL Database

First I will create a volume for MySQL to remain persistent. I will create a volume name is mysql-volume with the command below:

docker volume create mysql-volume

The output terminal is as below:

vagrant@devopsroles:~$ docker volume create mysql-volume
mysql-volume
vagrant@devopsroles:~$ docker volume ls
DRIVER    VOLUME NAME
local     1b944b2bc6253d6ef43a7fe8c0b57f7e070a219d495a69d89ee5e33ab3ffc48f

local     cb6583b8ad3d474f06e6c8fef30f5d4d11cb1a51e69ca0cc5d2df15a9deae1c3
local     ghost-blog_ghost
local     ghost-blog_mysql
local     my-postgres-db-db
local     mysql-volume

After our volume ready, we will deploy the MySQL container with named is devops_mysql and connect it to the volume with the command below:

docker run --name=devops_mysql -p3306:3306 -v mysql-volume:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123abc@ -d mysql/mysql-server

The output terminal as below

vagrant@devopsroles:~$ docker run --name=devops_mysql -p3306:3306 -v mysql-volume:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123abc@ -d mysql/mysql-server

Deploy the phpMyAdmin Container

I will deploy the phpMyAdmin Container. Create a volume for phpMyAdmin with the command line as below

docker volume create phpmyadmin-volume

The output terminal is as below:

vagrant@devopsroles:~$ docker volume create phpmyadmin-volume
phpmyadmin-volume
vagrant@devopsroles:~$ docker volume ls | grep phpmyadmin-volume
local     phpmyadmin-volume

deploy the phpMyAdmin container with the command:

docker run --name devops-phpmyadmin -v phpmyadmin-volume:/etc/phpmyadmin/config.usr.inc.php --link devops_mysql:db -p 82:80 -d phpmyadmin/phpmyadmin

The output terminal is as below:

vagrant@devopsroles:~$ docker run --name devops-phpmyadmin -v phpmyadmin-volume:/etc/phpmyadmin/config.usr.inc.php --link devops_mysql:db -p 82:80 -d phpmyadmin/phpmyadmin

vagrant@devopsroles:~$

The explanation of the above command

• Deploying a container named devops-phpmyadmin
• Linking to devops_mysql database
• external port is 82
• Internal port is 80
• running the container in daemon mode (with the -d option)

How to Access phpMyAdmin

Open a web browser and point it to http://SERVER:82

Log in with the username root and the password you used when you deployed the MySQL container.

For example, the username is root and the Password is 123abc@

Can not access MySQL docker as the picture below

How to fix it

docker exec -it devops_mysql mysql -u root -p
update mysql.user set host='%' where user='root' and host = 'localhost';
flush privileges;

The result, Login access to phpMyAdmin

How to access MySQL and phpMyAdmin containers

docker exec -it devops_mysql /bin/bash
docker exec -it devops-phpmyadmin /bin/bash

Conclusion

You have to Docker deploy MySQL and phpMyAdmin. I hope will this your helpful. Thank you for reading the DevopsRoles page!
