Install Docker

Install Docker

$ pamac install docker

# Start the Docker service
$ sudo systemctl start docker.service
# Make sure the Docker service keeps running after we restart the PC
$ sudo systemctl enable docker.service

# Check if it's working
$ sudo docker version

# Install some extras you probably want
# (for docker-compose)
$ pamac install docker-compose
# (for BuildKit build layer caching)
$ pamac install docker-buildx

You probably also want to pamac install docker-buildx otherwise, you will run into the following error when using Docker BuildKit (Docker build layer caching):

ERROR: BuildKit is enabled but the buildx component is missing or broken.
       Install the buildx component to build images with BuildKit:
       https://docs.docker.com/go/buildx/

Run Docker without root

By default, you’ll have to use sudo or login to root anytime you want to run a Docker command. This next step is optional, but if you’d prefer the ability to run Docker as your current user, add your account to the docker group with this command:

$ sudo usermod -aG docker $USER

You’ll need to reboot your system for those changes to take effect. [or you can just logout and log back in]
