In recent years, Docker has become a popular tool for developers to easily create, deploy, and run applications in a variety of environments. One popular use case for Docker is to run web applications, such as WordPress. WordPress is a powerful content management system that can be used to create websites, blogs, and even online stores. Installing WordPress with Docker on Ubuntu 22.04 is a great way to get started with this platform. In this article, we’ll walk through the steps necessary to install Docker on Ubuntu 22.04 and then use Docker to install and configure a WordPress site. Whether you’re a developer looking to streamline your workflow or a WordPress user looking for a more flexible hosting solution, using Docker to install WordPress on Ubuntu 22.04 is a great choice.
- Update the package list and upgrade the system:
sudo apt-get update
sudo apt-get upgrade
- Install prerequisite packages:
sudo apt-get install apt-transport-https ca-certificates curl gnupg lsb-release
- Add Docker’s official GPG key:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
- Add the Docker repository to your system:
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
- Update the package list:
sudo apt-get update
- Install Docker:
sudo apt-get install docker-ce docker-ce-cli containerd.io
- Verify that Docker is installed correctly:
sudo docker run hello-world
This should download a test image and run it in a container. If everything is installed correctly, you should see a message that says “Hello from Docker!”.
To install WordPress on a Docker Ubuntu 22.04, you can follow the steps below:
- First, you need to install Docker on your Ubuntu machine. You can install Docker by following the official Docker documentation for Ubuntu 22.04 or the guide above.
- Once Docker is installed, you can create a new Docker container using the following command:
sudo docker run --name wordpress -p 80:80 -d wordpress
This command will create a new Docker container named “wordpress” and expose port 80 on the host machine. The “-d” option runs the container in the background.
- Once the container is running, you can access the WordPress installation by navigating to http://localhost or http://your-ip-address in your web browser. You will see the WordPress setup screen, where you can configure your site and set up your admin account.
- To make your WordPress installation persistent, you can create a new Docker volume using the following command:
sudo docker volume create wordpress_data
This command will create a new Docker volume named “wordpress_data” that will store your WordPress data.
- To start a new Docker container with your persistent data volume, use the following command:
sudo docker run --name wordpressweb -p 8080:80 -d wordpress
By using this command, you can prevent any conflicts on port 80. Once done, you can access the WordPress installation steps on either http://localhost or http://your-ip-address.
