Once you have Kubernetes running on IPv6 only the next step is to install some apps.
This is my first post written on my new WordPress instance, hosted on Kubernetes IPv6 only. If you are reading it, then it is working 🙂
Of course apps have their own issues not being configured by default to work with IPv6, so for each app you need to test and work out what configuration details need to be tweaked (assuming the app supports IPv6 in the first place).
To start off with, I installed Kubeapps, to get an application management dashboard, and then used that to install WordPress.
With WordPress installed, I exported the content from my old blog and then imported it into the new instance, and tweaked a few WordPress settings.
The final step was to configure the Mythic Beasts reverse proxy, to make my blog available for legacy IPv4 users.

Kubernetes is an open source platform for managing containerised applications.
IPv6 is the next generation Internet protocol, and running on IPv6 only simplifies configuration and administration, and avoids the performance issues and complexities of IPv4 encapsulation, NAT, and conflicting private address ranges.
The default configuration of Kubernetes is IPv4, and there are few, and scattered, examples and guidance for setting up IPv6 dual stack, let alone single stack.
I have collected instructions from the different sources into a single guide to successfully deploy Kubernetes with IPv6 only.
See the guide for full instructions:
The blog post contains some additional background on what I did to gett the deployment working. The deployment was tested on Ubuntu 20.04 running on an IPv6 only virtual server from Mythic Beasts.

We ran out of IPv4 addresses a few years ago, and the cost has been steadily increasing, now over USD 25.00 per IPv4 address.
Meanwhile we are increasingly using technologies such as containerised deployments and mass deployment of Internet of Things (IoT) devices, seeing an increase in demand for addresses.
About 30% of the Internet now happily talks IPv6, with several countries having more than 50% IPv6, and for a server hosting environment there are many benefits to going IPv6 only.
IPv6 only hosting is available from several providers such as Mythic Beasts.
