+The current state of Workadventure in IPv6 only kubernetes
+---
+body:
+
+## Overview
+
+At ungleich we are often running software in IPv6 only environments
+and recently even more in IPv6 only Kubernetes clusters. Today we had
+a look at running [WorkAdventure](https://workadventu.re/) in an IPv6
+only kubernetes cluster.
+
+## Status
+
+At the moment it looks like as if WorkAdventure cannot run in IPv6
+only Kubernetes clusters. The frontend displays the infamous "Network
+Error" messages. When checking the backend, it displays an error that
+it cannot resolve the redis hostname, which [seems to be a bug in the
+resolver
+code](https://github.com/thecodingmachine/workadventure/issues/1657),
+as the hostname does resolve, albeit only to an IPv6 address.
+
+## The code
+
+As usual you can find our code in the
+[ungleich-k8s
+repository](https://code.ungleich.ch/ungleich-public/ungleich-k8s/src/branch/master/apps/workadventure),
+which contains development iterations at the moment:
+
+* v1: initial conversions from docker-compose using kompose
+* v2: Adjust manifests so that pods generally speaking run
+* v3: Turned into a helm chart with most services running stable
+
+## Next steps
+
+We are currently waiting to hear back from the redis bug report and
+will continue developing after the backend is running stable in an
+IPv6 only environment.
+
+If you are interested in this development, feel free to
