+
+## TL;DR
+
+Today we opened up two public container registries from ungleich.
+You can use them to pull container images released by ungleich or to
+utilise the container registry caches.
+
+## Overview
+
+* You can pull public ungleich container releases from https://harbor.ungleich.svc.p10.k8s.ooo/ungleich-public
+* You can use the hub.docker.com cache on https://harbor.ungleich.svc.p10.k8s.ooo/dockerhub
+* You can use the quay.io cache on https://harbor.ungleich.svc.p10.k8s.ooo/quayio
+* You can use the hub.docker.com cache on
+  https://harbor.ungleich.svc.c2.k8s.ooo/dockerhub (development cluster)
+* You can use the quay.io cache on
+  https://harbor.ungleich.svc.c2.k8s.ooo/quayio (development cluster)
+
+All registries are **IPv6 only** and the caches are intended to be used
+by [Data Center Light customers](/u/projects/data-center-light)
+to avoid the IPv4 throttling that one encounters when
+pulling images from IPv6 only VM.
+
+You can test the ungleich-public repository as follows:
+
+```
+harbor.ungleich.svc.p10.k8s.ooo/ungleich-public/ungleich-certbot:0.3.3
+```
+
+
+## Usage
+
+If you are using [cri-o](https://cri-o.io/) you can use a
+registries.conf as follows:
+
+```
+[[registry]]
+prefix = "docker.io"
+location = "harbor.ungleich.svc.p10.k8s.ooo/dockerhub"
+
+[[registry]]
+prefix = "quay.io"
+location = "harbor.ungleich.svc.p10.k8s.ooo/quayio"
+
+[[registry.mirror]]
+location = "harbor.ungleich.svc.c2.k8s.ooo/dockerhub"
+
+[[registry.mirror]]
+location = "harbor.ungleich.svc.c2.k8s.ooo/quayio"
+```
+
+## Next steps
+
+More caches are to follow and we will add a list of publicly available
+images in the future.
