## 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:

```
docker pull 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:

```
unqualified-search-registries = ["docker.io"]

[[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 and more of it

More caches are to follow and we will add a list of publicly available
images in the future. You can read more about
