Has anyone noticed k3s shutdown times (on containerd) are super fast if you remove the metrics-server? I tried all kinds of combinations and versions of k3s…. All with same results. Any ideas why?

Ubuntu 20

sudo curl -sfL <https://get.k3s.io> | INSTALL_K3S_CHANNEL=v1.25 sh -s - --disable=servicelb,traefik,local-storage,metrics-server --write-kubeconfig-mode 644

Super fast shutdown times If you add metric back:

sudo curl -sfL <https://get.k3s.io> | INSTALL_K3S_CHANNEL=v1.25 sh -s - --disable=servicelb,traefik,local-storage --write-kubeconfig-mode 644

It takes a full 90 seconds to shutdown or restart your linux server. So the pod is never getting killed.

That is a ubuntu default on shutdown…

it just kill’s hard after sigterm + 90 seconds

I think its the root cause of this, but no one ever calls out metric server? Am I mistaken? https://github.com/k3s-io/k3s/issues/2400

I need to shut down fast (automotive-ish application)…. Is why I am asking.

Having any pod at all will make systemd wait for the process to exit before cleaning up the mounts. It doesn't matter what pod it is.

There are examples of adding an shutdown trigger to run the killall script to hard stop the pods
