# Arch Linux OCI Images



[![pipeline status][pipeline]][commits]



Arch Linux provides OCI-Compliant container images in multiple repositories:

* [Weekly in the official DockerHub library][hub-arch]:

`podman pull docker.io/library/archlinux:latest` or `docker pull archlinux:latest`

* [Daily in our DockerHub repository][hub-containers]:

`podman pull docker.io/archlinux/archlinux:latest` or `docker pull archlinux/archlinux:latest`

* [Daily in our quay.io repository][quay-containers]:

`podman pull quay.io/archlinux/archlinux:latest` or `docker pull quay.io/archlinux/archlinux:latest`

* [Daily in our ghcr.io repository][ghcr-containers]:

`podman pull ghcr.io/archlinux/archlinux:latest` or `docker pull ghcr.io/archlinux/archlinux:latest`



Three versions of the image are provided: `base` (approx. 150 MiB), `base-devel`

(approx. 260 MiB) and `multilib-devel` (approx. 300MiB) containing the

respective meta package. All of them 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`.



While the images are regularly kept up to date it is strongly recommended

running `pacman -Syu` right after starting a container due to the rolling

release nature of Arch Linux.



All the images, with the exception of the official DockerHub library image, are

signed by using [cosign's keyless signing][openid-signing]. The images can be

verified with one of the following commands:

```sh

$ cosign verify docker.io/archlinux/archlinux:latest --certificate-identity-regexp="https://gitlab\.archlinux\.org/archlinux/archlinux-docker//\.gitlab-ci\.yml@refs/tags/v[0-9]+\.0\.[0-9]+" --certificate-oidc-issuer=https://gitlab.archlinux.org

$ cosign verify quay.io/archlinux/archlinux:latest --certificate-identity-regexp="https://gitlab\.archlinux\.org/archlinux/archlinux-docker//\.gitlab-ci\.yml@refs/tags/v[0-9]+\.0\.[0-9]+" --certificate-oidc-issuer=https://gitlab.archlinux.org

$ cosign verify ghcr.io/archlinux/archlinux:latest --certificate-identity-regexp="https://gitlab\.archlinux\.org/archlinux/archlinux-docker//\.gitlab-ci\.yml@refs/tags/v[0-9]+\.0\.[0-9]+" --certificate-oidc-issuer=https://gitlab.archlinux.org

```



## Principles

* Provide the Arch experience in a Docker image

* Provide the simplest but complete image to `base`, `base-devel` and

`multilib-devel` on a regular basis

* `pacman` needs to work out of the box

* All installed packages have to be kept unmodified



>>>

     ⚠️⚠️⚠️ NOTE: For Security Reasons, these images strip the pacman lsign key.

     This is because the same key would be spread to all containers of the same

     image, allowing for malicious actors to inject packages (via, for example,

     a man-in-the-middle). In order to create a lsign-key run `pacman-key

     --init` on the first execution, but be careful to not redistribute that

     key.⚠️⚠️⚠️

## Building your own image



[This repository][self] contains all scripts and files needed to create an OCI

image for Arch Linux.



### Dependencies

Install the following Arch Linux packages:



* make

* devtools (for the pacman.conf files)

* git (to fetch the commit/revision number)

* podman

* fakechroot

* fakeroot



Make sure your user can directly interact with Podman (i.e. `podman info` works).



### Usage

There are multiple `make image-XXX` targets, where each creates the

respective `archlinux:XXX` image based on the corresponding meta package.

Currently those include `base`, `base-devel` and `multilib-devel`.



## Pipeline



### Daily releases



Daily images are build with scheduled [GitLab CI][in-tree-CI] using our own

runner infrastructure. Initially root filesystem archives are constructed and

provided in our [package registry][self-package-registry]. The released

multi-stage Dockerfile downloads those archives and verifies their integrity

before unpacking it into an OCI image layer. Images are built using

[podman](https://podman.io/), which also publishes them to our external

repositories.



### Weekly releases



Weekly releases to the official DockerHub library use the same pipeline as

daily builds. Updates are provided as automatic [pull requests][github-docker-prs]

to the [official-images library][github-docker-arch], whose GitHub pipeline will

build the images using our provided rootfs archives and Dockerfiles.



### Development



Changes in Git feature branches are built and tested using the pipeline as well.

Development images are uploaded to our

[GitLab Container Registry][self-container-registry].



### Maintenance



Every year in June the content of the protected `GITLAB_PROJECT_TOKEN` variable needs to be replaced. To do this a GitLab admin needs to create a new [Access Token][access-tokens] with `api` and `write_repository` scope and the `Maintainer` role. This will create a new Bot User which needs to be given access to the protected `releases` branch.
