Docker is the future, its  introduced everywhere and you are able to deploy quickly  many containers applications in few minutes. i will show in this article the best way to install  fully wordpress in few minutes . please follow the instructions bellow.

To install the basic Docker please follow this article:

How to install Docker 

Now lets deploy the first application, How to deploy wordpress in Docker.

1-What we need

WordPress needs a LAMP stack to run. In this process, we are splitting that LAMP stack into two containers: one that runs the database (MySQL or MariaDB), and one that runs the webserver (PHP with Apache or PHP with Nginx).

Paste the YAML configuration  like this:

vi Install-wordpress.yaml

add the following :

version: '3.1'

services:

wordpress:
image: wordpress
restart: always
ports:
- 8080:80
environment:
WORDPRESS_DB_PASSWORD: example

mysql:
image: mysql:8
command: '--default-authentication-plugin=mysql_native_password'
# common options
restart: always
environment:
MYSQL_ROOT_PASSWORD: example

save and exit

docker-compose up will  build the images/containers for you and will bring everything up in seconds.

2-Install Docker-composer

Docker-composer orchestrator dont exist on basic repo of Centos . to do this you need to add the epel repos

 yum install epel-release
yum install docker-compose

 

To user docker-compse orchestrator you have to use the created yaml configuration file.

Lets  start

[root@osradar ~]# docker-compose -f Install-wordpress.yaml up &
