[BUG] Azure ARC logcollector is missing nodeSelector os = linux #353

Open adestis-mb opened 9 months ago

adestis-mb commented 9 months ago

Describe the bug When the Azure ARC connection is enabled it installs a deployment logcollector within namespace azure-arc. The deployment seems to be a linux application and is unable to run on Windows kubernetes nodes. However the deployment is missing a nodeSelector os = linux and therefore might get scheduled on Windows nodes. Here it fails with:

Failed to pull image "mcr.microsoft.com/azurearck8s/fluent-bit-collector:1.13.1": rpc error: code = NotFound desc = failed to pull and unpack image "mcr.microsoft.com/azurearck8s/fluent-bit-collector:1.13.1": no match for platform in manifest: not found

To Reproduce Steps to reproduce the behavior:

  1. Install new Hybrid AKS cluster with Azure ARC enabled
  2. Add Linux and Windows worker pools
  3. Drain the linux nodes

Expected behavior The deployment must be changed and a nodeSelector for linux must be added. See https://samcogan.com/kubernetes-pod-allocation-in-a-multi-os-cluster/

Thank you for reporting this., it is a known issue we discovered a couple of weeks ago in our testing as well. The Arc team is working on a fix.
