In this article, we are going to see how to install and configure Docker on Arch-based Linux Distributions. Docker is an open-source containerization platform used for building, running, and managing applications in an isolated environment. A container is isolated from another and bundles its software, libraries, and configuration files. Containers share resources with other containers running on the same host OS and provide OS-level isolation that is far more efficient than virtualization.
Installing Docker in Arch-based Linux Distributions
Step 1: Before installing Docker, update Software Repositories using the following command
$ sudo pacman -Syu
Step 2: Install Docker from the official arch repository
$ sudo pacman -S docker
Step 3: To verify the installation execute
$ sudo docker version
Step 4: Now, start the docker service by using systemctl command
$ sudo systemctl start docker.service
$ sudo systemctl status docker.service
Step 5: Once again use systemctl command to enable the docker service. Now, Docker will restart whenever your machine boots up.
$ sudo systemctl enable docker.service
Step 6: To use Docker without sudo privileges you will need to add your account to the docker group.
$ sudo usermod -aG docker $USER
Step 7: As a final check, let’s run a minimal Docker image to see whether Docker is working properly.
$ docker run hello-world
To uninstall Docker and all of its config files run:
$ sudo pacman -R docker
