    • Install Docker with the command:

      sudo apt install docker-ce

    • Verify that the service is active with the command:

      sudo systemctl status docker

      Expected output:

      ● docker.service - Docker Application Container Engine
     Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
     Active: active (running) since Tue 2020-05-19 17:00:41 UTC; 17s ago
TriggeredBy: ● docker.socket
       Docs: https://docs.docker.com
   Main PID: 24321 (dockerd)
      Tasks: 8
     Memory: 46.4M
     CGroup: /system.slice/docker.service
             └─24321 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

    • Configure the non-root user to allow them to run Docker with the command:

      sudo usermod -aG docker ${USER}

    • Restart the VM with the command:

      sudo reboot

    • Verify that the user has been added to the docker group correctly with the command:

      groups ${USER}

  • Install Docker-compose on the VM

    • Install Docker-compose on the VM with the following command:

      sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

    • Change the execution permissions so that compose can be used by the non-root user:

      sudo chmod +x /usr/local/bin/docker-compose

    • Verify that Docker-compose was installed correctly on the VM with the command:

      docker-compose --version

Now that the host has been created, we can access it and start building our project.
