The process of installing Docker in Linux system

In this blog, I will walk you through the process of installing Docker in simple steps. Installing Docker is a piece of cake. You only need to run a few commands and you are done!

The Linux used in this article is Ubuntu, so let’s get started!

Step 1: To install docker on Ubuntu machine, first let us update the packages.

After this, we are done with the prerequisites!

Now, let’s move on to installing Docker.

Step 3: Enter the following command to install the docker engine:

sudo apt-get install docker-engine

Step 4: Start the docker service:

sudo service docker start

Step 5: Now just to verify if docker is running successfully, let me show you how to pull the CentOS image from docker hub and run the CentOS container, to do this, just type the following command:

sudo docker pull centos

First, it will check the local registry for the CentOS image. If it is not found there, then it will go to docker hub and pull the image:

In this way, we have successfully pulled a centOS image from the docker hub and run the CentOS container:

sudo docker run -it centos
