Get started with docker

Docker is a software framework for building, running, and managing containers on servers and the cloud. The recommended way is to use docker in linux platforms.
You could install docker easily by following the commands in Ubuntu terminal.

First, update existing list of packages:

sudo apt update

Next, install a few packages which let apt use packages over HTTPS:

sudo apt install apt-transport-https ca-certificates curl software-properties-common

Then add the GPG key for the official Docker repository to your linux system:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

Add the Docker repository to APT sources:

echo deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Update your existing list of packages again(in case to add required):

sudo apt update

Make sure you are about to install from the Docker repo :

apt-cache policy docker-ce

install Docker:

sudo apt install docker-ce

You are done Check that docker daemon running:

sudo systemctl status docker
