Ever wonder how to exactly run WordPress within a Docker container? In this tutorial, brought to you by the server experts at RackNerd, we will cover a detailed and simple way to run WordPress on Docker Container in your CentOS VPS. If you don’t already have a VPS, you can deploy one by clicking here.

Why Use Docker?

Docker helps run your service in an isolated environment. Each container doesn’t require to have its own operating system and shares the kernel on host. Thus, the machine workload will be light weight and a single container can run multiple containers in same time. In addition, all, you will be saving memory and space on your VPS server.

So, let’s move on to our step by step guide on how run WordPress on Docker Container in your VPS.

STEP #1: Login to your VPS node

Here, we will be using a CentOS VPS to run WordPress on Docker

Run the below commands to Install docker on your CentOS VPS:

yum update

Next, install docker dependencies on your system:

yum install yum-utils device-mapper-persistent-data lvm2

At this point, Docker dependencies have been successfully installed on our VPS server.

STEP #2: Add Centos docker stable repo to your VPS server with below command

yum-config-manager –add-repo https://download.docker.com/linux/centos/docker-ce.repo

STEP #3: Once docker stable repo has been added, lets start installing docker running below command:

yum install -y docker-ce

By now, Docker has been successfully installed

STEP #4: Docker has been installed, now start docker and enable to automatically to start every time the server is booted.

systemctl start docker
systemctl enable docker

Now check status of docker service with command

systemctl status docker

At this time Docker has been setup, now we can move on to the next part of this tutorial, which is how to install WordPress on Docker.

Since we will be using a simple and automatic way to run WordPress, we would need “Docker Compose” Service to be installed on your VPS server

STEP #5: Run below commands to setup Docker Compose Service

curl -L “https://github.com/docker/compose/releases/download/1.23.1/docker-compose-$(uname -s)-$(uname -m)” -o /usr/local/bin/docker-compose

Once compose has been downloaded make it executable with below command

chmod +x /usr/local/bin/docker-compose

Now check docker compose version using below command,

docker-compose –version

STEP #6: Setting up WordPress on Docker

Create a new directory for WordPress by running below commands:

mkdir ~/wordpress/
cd ~/wordpress/

Create docker-compose.yml in the new directory wordpress.

In this tutorial we will be using the vi editor to create docker-compose.yml file run below command to enter editor and and paste the content below. Don’t forget to change the credentials.

vi docker-compose.yml

version: ‘3.3’



image: mysql:5.7


– db_data:/var/lib/mysql

restart: always



MYSQL_DATABASE: racknerdwordpress

MYSQL_USER: wordpress-rd

MYSQL_PASSWORD: wordpress-rd



– db

image: wordpress:latest


– “8000:80”

restart: always



WORDPRESS_DB_USER: wordpressrd


WORDPRESS_DB_NAME: wordpressrd


db_data: {}

Save and exit editor using wq!

STEP #7: Run this below command to create wordPress running on docker container

docker-compose up -d

You will now see an output like this:

STEP #9: Run below command to check WordPress running on your VPS

docker ps

You will notice two containers running, one is a WordPress container and another is MySQL database container.

STEP #10: Open a web browser on your computer and in the address bar, enter  VPS _server_IP:8000 and the WordPress setup screen will be displayed as below:
