Kube-proxy not found after setup #362

Closed yahbouss closed 2 months ago

yahbouss commented 7 months ago

Describe the bug I am trying to create kubernetes cluster with 1 windows node and ubuntu node. the ubuntu node joined successfully and it's working but the windows is not. I ran the hack/DebugWindowsNode.ps1 and it showed me an issue with kube-proxy.exe not running as a service

here is my investigation till now:

To Reproduce Steps to reproduce the behavior: I ran :

  1. ./Install-Containerd.ps1
  2. ./PrepareNode.ps1
  3. Kubeadm join ...
  4. curl.exe -LO https://raw.githubusercontent.com/kubernetes-sigs/sig-windows-tools/master/hostprocess/calico/kube-proxy/kube-proxy.yml
  5. (Get-Content "kube-proxy.yml") -Replace 'image: (.):(.)-(.)-(.)$', 'image: $1:v1.28.0-$3-$4' | Set-Content "kube-proxy.yml"
  6. kubectl apply -f kube-proxy.yml (after copying it to master node)

Expected behavior win-node should be ready, instead it is not ready

Kubernetes (please complete the following information):

Additional context When nothing worked, i tried changing the version of the kube-proxy, reverting it back, checking the logs of the containerd in the windows, and this is the log:

Can you try building the image on your own? We have not built every version of the flannel images
