-Arch Linux provides Docker images both in the [official DockerHub library](https://hub.docker.com/_/archlinux) (`docker pull library/archlinux:latest`) and in our [own repository](https://hub.docker.com/r/archlinux/archlinux) (`docker pull archlinux/archlinux:latest`).

 Two versions of the image are provided: `base` (approx. 150 MiB) and `base-devel` (approx. 260 MiB), containing the respective meta package / package group. Both are available as tags with `latest` pointing to `base`. Additionally, images are tagged with their date and build job number, f.e. `base-devel-20201118.0.9436`.

-Daily images are build with scheduled [GitLab CI](https://gitlab.archlinux.org/archlinux/archlinux-docker/-/blob/master/.gitlab-ci.yml) using our own runner infrastructure. Initially root filesystem archives are constructed and provided in our [package registry](https://gitlab.archlinux.org/archlinux/archlinux-docker/-/packages). The released multi-stage Dockerfile downloads those archives and verifies their integrity before unpacking it into a Docker image layer. Images are built using [kaniko](https://github.com/GoogleContainerTools/kaniko) to avoid using privileged Docker containers, which also publishes them to our DockerHub repository.
