Instruction for Installing Docker in Ubuntu linux OS

Update the apt package index and 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 Docker’s official GPG key:

sudo mkdir -m 0755 -p /etc/apt/keyrings

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

Set up the 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

Update the apt package index: 

sudo apt-get update

Install Docker Engine and Docker Compose

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

Verify that the Docker Engine installation is successful by running the hello-world image:
