Enable IPv6 on Kubernetes worker node Droplets

Mathew Kamkar

Even though Kubernetes does not support IPv6, pods running with host networking enabled can make use of the IPv6 address. IPv6 should be enabled by default or there can be an option to enable it for a Kubernetes node pool.

IPv6 Support for Kubernetes Cluster

I want to be able to access IPv6 addresses from inside a Pod.

kubernetes itself has fully ipv6 support. I've a own cluster running. that also assigns ipv6 adresses to every pod. Sadly DO has almost no ipv6 support on their services.

It is worth noting that this sort of already works. If you manually enable IPv6 on the nodes and reboot them everything seems to behave properly. The main issue is that node recycling, updates and autoscaling will create fresh nodes without IPv6 enabled. This makes it very hard to use as manual action is required after every automation process that recreates nodes.

So in theory the only thing that would be needed here is a checkbox to enable IPv6 for a node pool that gets propagated to new nodes. It would be fantastic if this could be added, even if it was marked as experiential.
