How to Install Docker on CentOS

CentOS is a popular Linux distribution known for its stability and long-term support. Docker, on the other hand, is a powerful tool for containerization that allows you to run applications in isolated environments. In this tutorial, we will walk you through the steps to install Docker on CentOS.

Step 1: Update System

Before installing any new software, it is essential to update your system to ensure you have the latest packages and security updates. To update your CentOS system, run the following command:

sudo yum update

Step 2: Install Docker Dependencies

Next, we need to install the required dependencies for Docker. Run the following command to install the necessary packages:

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

Step 3: Add Docker Repository

To install the latest version of Docker, you will need to add the Docker repository to your system. Run the following command to add the Docker repository:

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

Step 4: Install Docker

Now that we have added the Docker repository, we can proceed to install Docker. Run the following command to install Docker on CentOS:

sudo yum install docker-ce docker-ce-cli containerd.io

Step 5: Start and Enable Docker

After installing Docker, you need to start and enable the Docker service to ensure it starts automatically upon system boot. Run the following commands to start and enable Docker:

sudo systemctl start docker sudo systemctl enable docker

Step 6: Verify Docker Installation

To verify that Docker has been successfully installed on your CentOS system, run the following command:

docker --version

If Docker has been installed correctly, you should see the version of Docker installed on your system.
