Update aptand install packages to allow apt to use a repository over HTTPS

$ sudo apt-get update
$ sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

Add GPG key

$ sudo mkdir -p /etc/apt/keyrings
 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

Set up Docker repository

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

Install Docker engine

$ sudo apt-get update
$ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

Run the Hello-World image to verify the installation

$ sudo groupadd docker
$ sudo usermod -a -G docker ${USER}
$ newgrp docker
$ su -s ${USER}

This command is optional (In case if you run docker without adding the user first)

$ sudo chown "$USER":"$USER" /home/"$USER"/.docker -R
$ sudo chmod g+rwx "$HOME/.docker" -R

$ sudo service docker start
$ sudo docker run hello-world

This command downloads a test image and runs it in a container.
