Known issues

Update​

  • OS upgrade (Windows 10 to Windows 11) will result in AKS Edge Essentials failing to work properly​
  • "Unable to Start HCS VM" exception caught when running command "Start-AksEdgeControlPlaneUpdate -firstControlPlane True" If this error is encountered, the following commands can be used to recover the cluster
    import-module "C:\Program Files\WindowsPowerShell\Modules\1.3.186.0" -Force $nodeConfig = Get-NodeConfig -NodeType ([NodeType]::Linux) $ServiceIpRange = ParseServiceIpRange -ServiceIpRange $nodeConfig.ServiceIpRange $scriptArgs = @{ firstControlPlane = $firstControlPlane networkPlugin = $(Get-ClusterNetworkPlugin) controlPlane = $(Get-LinuxNodeHasControlPlane) controlPlaneEndpointIp = $(Get-ClusterControlPlaneEndpoint).ControlPlaneEndpointIp serviceIPRangeStart = $($ServiceIpRange.Start) serviceIPRangeEnd = $($ServiceIpRange.End) } Update-PostScriptLinuxVM @scriptArgs

Deployment​

  • Deploying a K8s Linux node on a 4GB RAM host machine fails
  • New deployment fails when the execution policy is set to AllSigned (Set-ExecutionPolicy –ExecutionPolicy AllSigned)​
  • Uninstalling and reinstalling k8s/k3s causes a “deployment already exists” error when creating a new deployment, so a restart is necessary​
  • Event logging fails when uninstalling and reinstalling an MSI without a reboot in between​
  • When a deployment fails due to lack of memory/disk space, it creates an incomplete VHDX file that causes errors in later deployments​
  • Deployment with External virtual switch fails when using Windows RS5

Linux nodes

  • When you use the Remove-AksEdgeNode to remove a node, it might still show up in the kubectl get nodes as the cluster tries to reconcile the state of the present nodes. Please note that the command Remove-AksEdgeNode is a asynchronous call and will return before the cluster state is updated to reflect the new state.

Windows nodes​

  • On a K3s Windows node, load balancer klipper-lb pulls images from the internet when connected​
  • Adding a Windows node takes around ~10 minutes to complete​
  • K3s Windows node with Calico as the CNI is not yet supported​
  • No storage provisioner is available for the Windows node​
  • NFS subdir external provisioner pod fails on Windows nodes​
  • Multi-Node update Fails to recreate Windows nodes

Arc Connection

  • Connecting a cluster that has Windows nodes to Arc may fail due to "logcollector*" pod getting stuck in Imageloopbackoff state.
