Tested on Ubuntu 19.04 host, fcwu/docker-ubuntu-vnc-desktop, dorowu/ubuntu-desktop-lxde-vnc image id: 70516b87e92d. Follow edited Jun 24 '20 at 9:52. The Docker daemon pulled the 'hello-world' image from the Docker Hub. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. Connect and share knowledge within a single location that is structured and easy to search. Now check the Docker service using the command below. Systemctl status docker. The Docker service is up and running on the Ubuntu 20.04. Next, run the docker command below to make sure the installation is correct. Docker run hello-world. Below is the result you will get. Hello from Docker!
