Understanding Docker
Before we get into the steps on how to install Docker Engine on CentOS 8, let’s first understand what Docker is and why it’s important. Docker is an open-source platform that allows developers to build, ship, and run applications in containers. These containers are lightweight, portable, and provide consistent environments for developers to work in.
Docker allows developers to package their applications and dependencies into containers, making it easy to move them from development to production environments. Docker also allows for faster application deployment, improved scalability, and reduced infrastructure costs.

Prerequisites
Before we can start with the installation of Docker Engine, we need to make sure that our CentOS 8 server meets the following requirements:
- A CentOS 8 server with root access.
- 2 GB or more of RAM.
- At least 20 GB of free disk space.
Step 1 – Update the System
The first step in installing Docker Engine on CentOS 8 is to make sure that the system is up to date. This can be done by running the following command:
sqlCopy codesudo dnf update -y
This command will update all the packages on your system to their latest version.
Step 2 – Install Docker Engine
Once the system is up to date, we can now proceed with the installation of Docker Engine. Docker Engine can be installed using the following command:
luaCopy codesudo dnf install docker-ce docker-ce-cli containerd.io -y
This command will download and install the latest version of Docker Engine on your CentOS 8 server.
Step 3 – Start and Enable Docker Service
After the installation is complete, we need to start the Docker service and enable it to start automatically on boot. This can be done by running the following commands:
bashCopy codesudo systemctl start docker
sudo systemctl enable docker
These commands will start the Docker service and enable it to start automatically on boot.
Step 4 – Verify the Installation
To verify that Docker Engine is installed correctly, we can run the following command:
arduinoCopy codesudo docker run hello-world
This command will download a test image and run it in a container. If the installation is successful, you should see a message that says “Hello from Docker!”.
Step 5 – Install Docker Compose (Optional)
Docker Compose is a tool that allows developers to define and run multi-container Docker applications. If you plan on using Docker Compose, you can install it using the following commands:
bashCopy codesudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
These commands will download and install the latest version of Docker Compose on your CentOS 8 server.
