Bug in bootstrapping

Open blackliner opened this issue 2 months ago • 0 comments

https://github.com/cozystack/talos-bootstrap/blob/29259af0d6d0e4ec696b6f69964c5087515f94a3/talos-bootstrap#L532 uses the VIP to bootstrap, but I don't think the VIP will be claimed by a non-bootstrapped CP. If that would be the case, then multiple CP would fight for the VIP before even forming a cluster.

Confirmed: https://docs.siderolabs.com/talos/v1.8/networking/vip#caveats

Caveats Since VIP functionality relies on etcd for elections, the shared IP will not come alive until after you have bootstrapped Kubernetes. Don’t use the VIP as the endpoint in the talosconfig, as the VIP is bound to etcd and kube-apiserver health, and you will not be able to recover from a failure of either of those components using Talos API.
