Docker deploy MySQL and phpMyAdmin

#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     c6e1ca4cc9617ca9031d974f4d19a5efbac96102850aa255d07c9dc53bd7f6e4
local     c509424aaaeda0374dc1d3d849bc245a183e865cddffa4bc1606d736ee3fb615
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

Docker deploy MySQL and phpMyAdmin

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@

flush privileges;
Docker deploy MySQL and phpMyAdmin 02

The result, Login access to phpMyAdmin

Docker deploy MySQL and phpMyAdmin 03

How to access MySQL and phpMyAdmin containers

docker exec -it devops_mysql /bin/bash
