Today, you will learn how to install docker on Linux or more specifically, Arch Linux. You can follow the steps for debian and Red Hat based systems as well. Just the package installation will be bit different.

Check the docs:

• Debian
• Ubuntu
• Fedora
• Red Hat

Step 1: Update the System (Optional)

Update the system with:

sudo pacman -Syu

Step 2: Install Docker

Install Docker using the following command:

sudo pacman -S docker

Step 3: Start and Enable Docker Service

Start the Docker service and enable it to start on boot:

sudo systemctl start docker
sudo systemctl enable docker

Step 4: Add User to Docker Group

To avoid using sudo with every Docker command, add your user to the Docker group:

sudo usermod -aG docker $USER

After adding the user to the Docker group, log out and log back in for the changes to take effect.

Step 5: Verify Docker Installation

Verify that Docker is installed correctly by running:

docker --version

You can also run a test container to ensure everything is working:

docker run hello-world

That's it! Docker should now be installed and ready to use on your Arch Linux system.
