Check Pod resources are healthy

kubectl get pod -A

If there are any pods in Pending state - check if the reason is insufficient resources and scale the MachineDeployment resources accordingly.

You can scale MachineDeployment resource(s) with following command: kubectl scale machinedeployment -n kube-system <md-name> --replicas=2.

If there are some failing pods, investigate the specific logs.

Check Flux kustomizations are applied

kubectl get kustomizations.kustomize.toolkit.fluxcd.io -A

Should provide an output like:

NAMESPACE     NAME                 READY   STATUS                                                            AGE
