IPv6 only kubernetes clusters

This project is testing, deploying and using IPv6 only k8s clusters.

Docs

• Setting up the cluster with calico
• Bootstrapping Rook

Working

• networking (calico)
• ceph with rook (cephfs, rbd)

Not (yet) working or tested

• virtualisation (VMs, kubevirt)
• letsencrypt
• network policies
• prometheus in the cluster
• argocd (?) for CI and upgrades
• Maybe LoadBalancer support (our ClusterIP already does that though)
• (Other) DNS entrys for services

Cluster setup

• Calico CNI with BGP peering to our upstream infrastructure
• Rook for RBD and CephFS support

Init

We are using a custom kubeadm.conf to

• configure the cgroupdriver
• configure the IP addresses

kubeadm init --config v3-calico/kubeadm-config-p7-v2.yaml
