Native Hardware means a physical laptop or desktop computer. If you are using WSL on Windows, then you should be installing Docker Desktop for Windows NOT Linux. If you are installing within a VM like VirtualBox or Parallels, or, a cloud server such as AWS, then, you must use the Installation on Cloud Servers or inside Virtual Machines instructions instead. Docker Desktop does not work with nested virtualization.
Currently Docker Desktop currently only works with the Ubuntu, Debian, or Fedora distributions. If you are using any other distribution, you will need to follow the "Installation on Cloud Servers or inside Virtual Machines" instructions.
Create Dockerhub account

Install Docker Desktop for Linux
Simply follow the generic installation instructions for your particular distribution:
https://docs.docker.com/desktop/install/linux-install/#generic-installation-steps
Login to the Dockerhub
In order to push and pull images, you will need to log in to the Dockerhub. In your terminal, run docker login and then enter your Dockerhub account username and password.
Test Docker installation
After completing the installation steps, test out Docker by running docker run hello-world. This should download and run the test container printing "hello world" to your console.
The steps listed below are for Ubuntu Desktop LTS. You can find the full official docs and steps for other Linux distributions here:
Ubuntu: https://docs.docker.com/install/linux/docker-ce/ubuntu/
CentOS: https://docs.docker.com/install/linux/docker-ce/centos/
(Note: Students have encountered issues when using CentOS or RHEL as the host related to Docker container communication. You may need to research some workaround for the errors you run into or search the QA for already posted solutions)
Debian: https://docs.docker.com/install/linux/docker-ce/debian/

Install Docker
The Docker docs suggest setting up a Docker repository to install and update from.
This is where you should start: https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository
Login to the Dockerhub
In order to push and pull images, you will need to log in to the Dockerhub. In your terminal, run docker login and then enter your Dockerhub account username and password.
Test Docker installation
After completing the installation steps, test out Docker by running sudo docker run hello-world. This should download and run the test container printing "hello world" to your console.
Testing Docker Compose
Important! The version of Docker Compose that is now installed with Docker does not include a symlink to the docker-compose (with a hyphen) command. This only exists in Docker Desktop. So, all commands should be run without a hyphen.
After completing, test your installation by running:
docker compose -v
This should print the version and build numbers to your console.
Run without Sudo
Follow these instructions to run Docker commands without sudo:
https://docs.docker.com/install/linux/linux-postinstall/#manage-docker-as-a-non-root-user
Start on Boot
Follow these instructions so that Docker and its services start automatically on boot:
https://docs.docker.com/install/linux/linux-postinstall/#configure-docker-to-start-on-boot
You may need to restart your system before starting the course material.
