Docker is a containerization technology used for packaging and distributing applications. In this tutorial, we will learn how to install Docker on Arch Linux.
Before you start, ensure that your system is up-to-date. You can do so by running the following command:
sudo pacman -Syu
To install Docker on Arch Linux, follow the below steps:
docker package using the pacman package manager:sudo pacman -S docker
sudo systemctl enable docker.service
sudo systemctl start docker.service
sudo docker run hello-world
This command will download a Docker image, run a container, and print a "Hello World!" message. If the command returns the message "Hello from Docker!" then Docker is installed correctly.
By default, Docker commands require root privileges. However, it is recommended to create a non-root user account for managing Docker. Follow the below steps to create a non-root user:
docker:sudo groupadd docker
docker group:sudo usermod -aG docker $USER
Log out and log back in to apply the group membership changes.
Verify that you can run Docker commands without sudo:
docker run hello-world
This command should run without any errors.
In this tutorial, we learned how to install Docker on Arch Linux. We also created a non-root user account for managing Docker. Now, you can start building and deploying your applications using Docker.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
