# Installing Docker on Arch Linux
> Mon 7th March 2022 By David T. Sadler.
## Installing Docker
Docker is installed via pacman.
```shell
$ sudo pacman -S docker
```
## Starting Docker Engine
Start the Docker daemon which provides the Docker Engine. This process serves the Docker API and manages Docker containers.
```shell
$ sudo systemctl start docker.service
```
If you want Docker Engine to automatically start when you system boots issue the below command.
```shell
$ sudo systemctl enable docker.service
```
Verify that Docker Engine is running.
```shell
$ docker info
```
Verify that you can run containers. The below will download the latest Arch Linux image and use it to run a "Hello World" bash script in the container.
```shell
$ docker run -it --rm archlinux bash -c "echo Hello World"
```
## Problems
You may get an error when running docker info.
```shell
$ docker info
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/containers/json: dial unix /var/run/docker.sock: connect: permission denied
```
The issue is that the user you're running the docker command as is not a member of the docker group. Therefore you can either run the command via sudo or add your user to the docker user group, re-login, and restart docker.service.
