Any way to change the VIP address?

We need to change the static IP down due to an oversight in our IP convention

@witty-jelly-95845 Any suggestions?

Do you have one node or multiple ?

Currently we have 2 nodes

According to https://github.com/harvester/harvester/issues/2063#issuecomment-1094281911 theoretically VIP could be changed but ...

Welp time to rebuild for the second time

I scaled down to a single harvester instance

Our node IP is fine

I've found VIP using kubectl

kubectl get service -n kube-system ingress-expose

but I'm not about to try changing that without more digging (it must be configured somewhere so nodes know what to talk to) plus I need my cluster working right now!

That worked

I found all references to the old ip and changed it

Well I suppose if you're going to reinstall anyway 🤓

We just need to reinstall our other nodes

kubectl get all -o yaml --all-namespaces | grep "old_ip"

though I hear

kubectl get all

is deprecated

kubectl edit configmaps -n harvester-system vip

You also have to delete

serving-cert

and restart internal rancher

kubectl get all

being deprecated, https://github.com/kubernetes/kubectl/issues/151 was an interesting read!
