This tutorial explains, how to install docker on Ubuntu.

Docker

Docker is a platform that combines applications and its dependencies in the form of packages called a container. We can run multiple containers on a single Operating System. Containers are not Virtual Machines. Virtual Machines requires Operating System to run applications, but containers do not. As containers don’t need an Operating System, it takes very little time to start and hence it is very faster than Virtual Machines.

Also delete all Docker Images, Containers, and Volumes that not automatically remove.

Pick Your Operating System

You came here to ask, 'how do I install Docker?' The answer can be straightforward if you're willing to accept my way, but the steps differ based on which operating system is utilized. To make things more complicated, there are a few ways to install Docker on your OS that are largely based on preference. Today I'm going to walk you through my preferred method. This isn't the only way, but I've found it to be the best way to get up and running with ease. For Ubuntu, we'll be setting up the Docker Engine. For Windows and macOS, we'll be using Docker Desktop.

Click on any of the links below to get started with installing Docker.

Installing Docker on Ubuntu

For Ubuntu, we're going to install Docker Engine and Docker Compose using the Docker and Compose repositories. This also happens to be the recommended approach by Docker.

Set Up

1. Delete any prior versions if you had installed them.

2. Update your system and install the necessary dependencies.

3. For security purposes, add Docker's official GPG key. Read more about that here.

4. Set up the stable repository.

That's quite a few steps, but if you followed along exactly, you should be ready to install Docker!

Installation

1. Install the latest version of Docker, along with its dependencies.

2. Verify your install by running your first image.

3. Add your user as an admin to the Docker user group.

Doing this last step means you no longer have to append sudo to run Docker commands!

Uninstall

Fed up with Docker on your Ubuntu box? Uninstall and remove the configuration files with the following commands.

Installing Docker Compose on Ubuntu

Install

You must have completed the installation of Docker Engine in the steps above before you can install Docker Compose. Assuming you've done so without any errors, let's continue on!

1. Download the stable release of Docker compose.

Unlike the installation for Docker Engine where it automatically installs the latest version, Docker Compose has to have the version manually specified. At the time of writing, the latest version is 1.29.2. The latest version can be viewed at the Compose repository release page on GitHub. Feel free to substitute the version in the command above as needed.

2. Make the downloaded binary executable.

Uninstall

To remove Docker Compose, utilize the following command (assuming you installed with curl as we did above).

Installing Docker Desktop on macOS

Note that Docker Desktop comes pre-equipped with Docker Engine, Docker Compose, Kubernetes, and a few other goodies.

Installation

Intel or Apple Silicon

Depending on which chipset you have on your Mac, you'll need to install one of two versions of the Docker Desktop application. As this is a GUI application, there's not much needed other than navigating to the correct site and installing the .dmg file. Just drag and drop the Docker icon into your Applications directory.

Docker for macOS with Intel

The official link for installing Docker Desktop for macOS with an Intel chipset can be found here.

Apple Silicon

We'll also need to take a few prior steps to get Docker Desktop running with Apple Silicon. Namely, you'll need to install Rosetta 2 with the following command.

Afterward, install Docker Desktop for macOS with an Apple Silicon chipset from here.

Sudo Apt Install Docker.io Ubuntu

Uninstall

Within the Docker Desktop toolbar item, navigate to the menu > Troubleshoot > Uninstall. See the screenshot below.

Installing Docker Desktop on Windows and WSL2

Note that Docker Desktop comes pre-equipped with Docker Engine, Docker Compose, Kubernetes, and a few other goodies. Firstly, you will need Docker Desktop even if you want Docker to only run on WSL. This is due to the sandboxed nature of WSL.

Installation

Windows

1. First, you'll need to ensure that virtualization is enabled for your CPU in the BIOS. This differs amongst motherboard manufacturers and chipsets (namely Intel and AMD). A quick Google search will get you going though.
2. The executable for Docker Desktop for Windows can be found here. It can also be found on Docker Hub. Click the installer, follow the prompts and wait for it to be downloaded.

Sudo Apt Install Docker

3. During the process, be sure to allow the prompts for Enable Hyper-V Windows Features and the Install required Windows components for WSL 2.

WSL2

You'll need to complete the steps for installing Docker Desktop on Windows before you can utilize WSL2. However, once you've completed it, feel free to come back to this section.

1. Enable Use the WSL2 based engine in the Docker Desktop for Windows settings and Apply & Restart.

2. Be sure that WSL2 is set as your default and current distribution.

Check the current WSL mode.

If not set to v2, upgrade your existing Linux.

Set v2 as the default version.

3. Navigate to WSL Integration and make sure Enable Integration with my default WSL distro is checked.

Uninstall

Docker Desktop can be uninstalled from the Apps & features system settings. Just search for Docker Desktop and select Uninstall. Follow the prompts.
