Docker installation on CentOS 7

Are you looking to set up Docker on your CentOS 7 system? Docker is a powerful tool that allows you to automate the deployment of applications in lightweight, portable containers. In this guide, we will walk you through the process of installing Docker on CentOS 7 so that you can start taking advantage of its features.

Step 1: Update your system

Before we begin the Docker installation process, it’s important to ensure that your CentOS 7 system is up to date. You can do this by running the following commands:

sudo yum update

Step 2: Install required packages

Next, we need to install the necessary packages to support Docker on CentOS 7. Run the following command to install these packages:

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

Step 3: Add Docker repository

Now, we need to add the Docker repository to our package manager. 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

With the repository added, we can now install Docker. Run the following command to install Docker on your CentOS 7 system:

sudo yum install docker-ce

Step 5: Start and enable Docker

Once Docker is installed, you can start and enable the Docker service by running the following commands:

sudo systemctl start docker sudo systemctl enable docker

Step 6: Verify installation

To ensure that Docker has been successfully installed on your CentOS 7 system, you can run the following command to check the Docker version:

docker --version

That’s it! You have successfully installed Docker on your CentOS 7 system. You can now start using Docker to deploy and manage your applications in containers. Happy coding!
