It is available in the Extra repository and you can simply [do the pacman magic][1]: + +``` + + sudo pacman -S docker + +``` + +But there are more steps involved here to run Docker on Arch Linux properly. + +### Making Arch Docker ready + +It all comes down to these steps: + + * Install Docker from Arch repository + * Start the Docker daemon and run it automatically at each boot + * Add user to docker group to run docker commands without sudo + + + +Let's see the steps in detail. + +#### Step 1: Installing Docker package + +Open the terminal and use the following command: + +``` + + sudo pacman -S docker + +``` + +Enter the password and press Y when asked for it. + +![][2] + +It may take some time depending on the mirror you are using. + +💡 + +If you see a package not found or 404 error, your sync database is perhaps old. Update the system (it will download a lot of packages and take time) with: sudo pacman -Syu + +#### Step 2: Start docker daemon + +Docker is installed but it is not running. You should start the dcoker daemon before **running the Docker command for the first time** : + +``` + + sudo systemctl start docker.service + +``` + +I also suggest enabling the Docker service so that the docker daemon starts automatically when your system boots. + +``` + + sudo systemctl enable docker.service + +``` + +This way, you can just start running docker commands. You won't need to manually start the docker service anymore. + +![][3] + +#### Step 3: Add user to docker group + +Docker is installed and the Docker service is running. You are almost ready to run docker commands. + +However, by default, you need to use sudo with docker commands. And that's annoying. + +To avoid using sudo with each docker command, you can add yourself (or any other user) to the docker group like this: + +``` + + sudo usermod -aG docker $USER + +``` + +**You must log out (or close the terminal) and log back in for the above change to take effect. If you don't want to do that, use this command:** + +``` + + newgrp docker + +``` + +Now the stage is set. Let's test it. + +#### Step 4: Verify docker installation + +There is a tiny docker image provided by docker itself to test the docker installation. Run it and see if everything works well: + +``` + + docker run hello-world + +``` + +You should see output like this for successful docker run: + +![][4] + +Congratulations! You have successfully installed Docker on Arch Linux. + +### Optional: Install Docker Compose + +Docker Compose has become an integral part of Docker. It allows you to manage multiple container applications. + +The older classic compose is provided by the `docker-compose` Python package. Docker has also ported it to Go and provides it with `docker compose` but this package comes with [Docker Desktop][5]. + +At this stage, I would suggest going with the classic docker-compose plugin and install it with this command: + +``` + + sudo pacman -S docker-compose + +``` + +![][6] + +### Troubleshooting Tips + +Here are some common issues you may face and the possible solutions: + +#### Tab completion not working for docker sub commands + +If you want to use tab completion for the docker command options (like completing im to images etc), install the bash-completion package: + +``` + + sudo pacman -S bash-completion + +``` + +Close the terminal and start a new one. You should be able to use tab completion with Docker commands now. + +#### Cannot connect to the Docker daemon error + +If you see the following error: + +``` + + docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?. + See 'docker run --help'. + +``` + +That's because the docker daemon is not running. Refer to step 2 and start the docker service, make sure it is running and enable it so that docker daemon runs automatically at each boot. + +``` + + sudo systemctl start docker.service + + sudo systemctl enable docker.service + +``` + +#### Permission denied while trying to connect to Docker daemon socket + +If you see this error: + +``` + + docker: permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create": dial unix /var/run/docker.sock: connect: permission denied. + See 'docker run --help'. + +``` + +That's because you need to either run the docker command with sudo or add the user to docker group to run docker commands without sudo. + +I hope this quick post helps you run Docker on Arch Linux. + +-------------------------------------------------------------------------------- + +via: https://itsfoss.com/install-docker-arch-linux/ + +作者：[Abhishek Prakash][a] +选题：[lujun9972][b] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://itsfoss.com/author/abhishek/ +[b]: https://github.com/lujun9972 +[1]: https://itsfoss.com/pacman-command/ +[2]: https://itsfoss.com/content/images/2023/10/installing-docker-arch-linux.png +[3]: https://itsfoss.com/content/images/2023/10/start-docker-daemon-arch-linux.png +[4]: https://itsfoss.com/content/images/2023/10/docker-running-successfully-arch-linux.png +[5]: https://www.docker.com/products/docker-desktop/ +[6]: https://itsfoss.com/content/images/2023/10/install-docker-compose.png
