Install Docker-CE on Ubuntu 20.04 LTS
On earlier versions of Ubuntu such as 18.04, we have to install a couple of dependencies manually including its repository. However, in Ubuntu 20.04, we don’t have to do anything, everything is there in the official repository of the system. What we have to do is the issuing of just one single Docker installation command and that‘s it. Here is the that:
sudo apt install docker-compose
Output for the above command:
Output for the above “Y” command:
Test docker command:
docker --version
Output for the above command:
Create "hello-world" docker container
So, finally, the Docker is on our Focal Fossa, its time to run and check whether it is able to pull container images from Docker Hub.
sudo docker pull hello-world
Output for the above command:
Run the downloaded image
sudo docker run hello-world
Output for the above command:
So, this was the simple tutorial on the installation of Docker for Ubuntu 20.04 Focal Fossa.

View the installed image
sudo docker ps -a
View the downloaded image
sudo docker images
Run the installed image
Run ubuntu with name=test:
