Installing docker on centos 7

Installing Docker on CentOS 7

Are you looking to leverage the power of Docker on your CentOS 7 machine? Look no further! Docker is an incredible tool that allows you to run software packages called containers. These containers are lightweight and easy to manage, making it a popular choice among developers and system administrators.

In this guide, we will walk you through the steps to install Docker on your CentOS 7 operating system. So let’s dive in and get started!

Step 1: Update and Upgrade your System

Before we begin the installation process, it is important to ensure that your CentOS 7 system is up to date. To do this, open up your terminal and run the following commands:

sudo yum update

sudo yum upgrade

Step 2: Install Required Dependencies

Next, we need to install the required dependencies for Docker to run smoothly on CentOS 7. To do this, run the following command in your terminal:

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

Step 3: Add the Docker Repository

Now, we need to add the Docker repository to our system. Run the following command to add the repository:

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

Step 4: Install Docker Engine

Finally, it’s time to install the Docker Engine on your CentOS 7 machine. Run the following command to install Docker:

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

Step 5: Start and Enable Docker

Once the installation is complete, start and enable the Docker service on your CentOS 7 system with the following commands:

sudo systemctl start docker

sudo systemctl enable docker

Step 6: Verify Docker Installation

To ensure that Docker has been installed correctly on your CentOS 7 machine, run the following command to check the Docker version:

docker --version

Congratulations! You have now successfully installed Docker on your CentOS 7 system. You are now ready to start using Docker and take advantage of its containerization capabilities. Happy containerizing!
