The Easy Guide To Install WordPress With Docker

Docker, a software facilitating the utilization and creation of containers, proves instrumental in deploying WordPress. In this discussion, we explore the advantages of employing Docker and walk through the steps of installing WordPress.

Let’s commence.

Advantages of Utilizing Docker

Setting up WordPress necessitates a well-structured stack, such as LAMP (Linux, Apache, MySQL, PHP) or LEMP (Linux, Nginx, MySQL, PHP). The installation of these components can be time-intensive, limiting your ability to experiment with code. This is where Docker becomes invaluable.

Docker leverages containers to generate, deploy, and operate applications. Each container provides a self-contained environment for configuring your stack, libraries, and dependencies. Varied containers can host diverse configurations, allowing you to install WordPress with Apache in one container and Nginx in another. Container activation and deactivation are at your discretion. Utilizing tools like Docker Compose enables the seamless execution of multi-container applications.

  1. Versatility in Server Configurations

A distinctive advantage of Docker lies in its adaptability to configure diverse server stacks. Varied containers can support different server configurations, enabling the installation of WordPress with Apache in one container and Nginx in another. This tailoring accommodates specific preferences seamlessly.

  1. Optimized Resource Management

Docker containers exhibit lightweight characteristics and share the host OS kernel, optimizing resource utilization. This results in swift deployments and an environment that is both resource-efficient and scalable.

  1. Multi-Container Applications through Docker Compose

Docker Compose, a utility for delineating and executing multi-container Docker applications, amplifies the simplicity of overseeing your WordPress setup. Utilizing a straightforward docker-compose.yml file, you can specify the services, networks, and volumes for your WordPress environment.

  1. Installation Process Tailored for Users

The installation guide is crafted with user-friendliness in mind, ensuring accessibility for novices and seasoned users alike. The straightforward steps, coupled with Docker’s capabilities, streamline the establishment of a WordPress instance, making it an uncomplicated and efficient undertaking.

How to install WordPress with Docker

Wordpress with docker

To establish your WordPress installation, only two containers and a Docker compose file are required.

Installing WordPress with Docker requires the presence of Docker, Docker-Compose, and a docker-compose.yml file on your server. To proceed with the installation, please follow these steps:

1. Install Docker Using the Official Repository:

If you are installing Docker for the first time, follow these steps to set up the Docker Repository. If you already have the Docker repository set up, skip to steps 5 & 6.

   – Update the apt package index:


     sudo apt-get update


   – To use a repository over HTTPS, install packages for apt:


     sudo apt-get install \

         apt-transport-https \

         ca-certificates \

         curl \

         gnupg-agent \Add Docker’s official GPG Key




   – Add Docker’s official GPG Key:


     curl -fsSL | sudo apt-key add -



   – Set up the stable repository:



     sudo add-apt-repository \

        "deb [arch=amd64] \

        $(lsb_release -cs) \



   – To update the apt package index:


     sudo apt-get update


     sudo add-apt-repository \

        "deb [arch=amd64] \

        $(lsb_release -cs) \



   – Then, install the latest version of Docker CE and containers:


     sudo apt-get install docker-ce docker-ce-cli


2. Install Docker-Compose:

   – Download the current stable release of Docker Compose:


     sudo curl -L "$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose


   - Apply executable permissions to the binary:


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



3. Create a docker-compose.yml File:

   To install WordPress, set up two containers (one for WordPress and one for the Database). Use a single docker-compose.yml file with the following content:


   version: '3'




          - db

        image: wordpress:latest


          - wp_data:/var/www/html


          - "80:80"


         condition: on-failure


          WORDPRESS_DB_HOST: db:3306

          WORDPRESS_DB_USER: wordpress

          WORDPRESS_DB_PASSWORD: my_wordpress_db_password


        image: mariadb


          - db_data:/var/lib/mysql


         condition: on-failure


          MYSQL_ROOT_PASSWORD: my_db_root_password

          MYSQL_DATABASE: wordpress

          MYSQL_USER: wordpress

          MYSQL_PASSWORD: my_wordpress_db_password






4. Prepare Docker-Compose:

   Move the docker-compose.yml file to a location you can easily access (e.g., ~wordpress/docker-compose.yml). From that directory, run the following command:


   docker-compose up -d


5. Start WordPress:

   Your WordPress installation is now complete and ready to be set up. Access the setup page by visiting the IP address of your server.


What is Docker, and why should I use it to install WordPress?

Docker is a platform that facilitates the use of containers for deploying and running applications. Using Docker to install WordPress provides a modular, self-contained environment, allowing easy setup, management, and flexibility to experiment with various configurations.

How many containers do I need to install WordPress with Docker?

You only need two containers – one for WordPress and one for the database (such as MySQL or MariaDB). These containers work together seamlessly to create a robust WordPress environment.

Can I customize the server stack when using Docker to install WordPress?

Yes, Docker allows for customization of the server stack. Different containers can run different server configurations. For example, you can install WordPress with Apache in one container and Nginx in another, providing flexibility and customization options.

Is it necessary to have prior experience with Docker to follow the installation guide?

No, the installation guide is designed to be user-friendly, even for those with minimal Docker experience. The step-by-step instructions ensure a smooth installation process, making it accessible for both beginners and experienced users.

How can I update my WordPress installation after using Docker to set it up?

Updating your WordPress installation is straightforward with Docker. Simply pull the latest Docker images for WordPress and MariaDB, update your docker-compose.yml file with the new image versions, and then run docker-compose up -d from your installation directory. This ensures your WordPress environment stays current with the latest releases.


In conclusion, the straightforward guide provided here simplifies the process of installing WordPress with Docker, offering an efficient and flexible solution. By leveraging Docker and Docker-Compose, users can effortlessly set up a WordPress environment, streamlining the deployment of containers for both WordPress and the associated database. 

This approach not only saves time but also provides the versatility to customize and experiment with different configurations. With just a few containers and a well-structured docker-compose.yml file, users can establish their own WordPress installation, enjoying the benefits of a self-contained and easily manageable environment.
