What's been sitting in my Obsidian notes for over a year now, I finally took the time to put it up on my blog. I have a few more blog posts coming up as part of this series. #kubernetes #ipv6 #cilium netops2devops.net/series/kuber...

part1 covers underlying #ipv6 infrastructure requirements before installing #kubernetes netops2devops.net/series/k8s-c...

part2 covers building the simplest #IPv6 only #k3s cluster using @cilium.io netops2devops.net/series/k8s-c...

topics for subsequent posts: - IPv6 address planning to run #cilium in native routing with cluster pool vs. multi-pool ipam. - Cilium BGP control plane with LB IPAM and GatewayAPI for ingress - Predictable egress IP without using an egress gateway (aka no SNAT/masquerading) Stay tuned ;)

Also cover BGP ECMP/Anycast of pods + seperate GUA addressing for unique unicast per node to eliminate the need for GENEVE or other host-to-host tunnelling. Would love to see a single blog post or blog post that covers this end-to-end.

I’m planning to cover just that in part4. Still working on part 3 this week😅 but yes I do have a working architecture/config with #cilium that uses native routing i.e no tunneling or masquerading. Each namespace gets a clean /64 using multi-pool ipam. POD addresses announced via BGP.
