following those docs and this config generator script allows for baremetal pure-ipv6 kubernetes nodes spinup using a ubuntu LXC container

all kube packages provided by snap inside the container and configured using "snap set"

cri-o provided by apt official repo in download.opensuse.org/repositories/

advice: use groupfs instead of systemd for cri-o

calico configs for baremetal ipv6 networking are included

hurricane-electric ddns updater for cert-manager here allows certs provision to apps

node commands:

shared root :shrugs:

mount --make-rshared /

set pure-ipv6 options to kubelet from snap:

snap set kubelet \
config=/var/lib/kubelet/config.yaml \
container-runtime=remote \
container-runtime-endpoint=unix:///run/crio/crio.sock \
feature-gates=IPv6DualStack=true \
kubeconfig=/etc/kubernetes/kubelet.conf \
network-plugin=cni \
node-ip=$(ip -6 -o addr show dev eth0| awk "{split(\$4,a,\"/\");print a[1]}" |grep 2001)

kill the cluster:

kubeadm reset -f && rm -rf /etc/kubernetes/ && systemctl daemon-reload && systemctl stop snap.kubelet.daemon && crictl stopp $(crictl pods -q --no-trunc) && crictl rmp -a && rm -f ~/.kube/config && ip link delete cni0 && snap restart kubelet.daemon
