I would start with this command in order to check pods that have frequent restarts:
kubectl get pods --all-namespaces Then run this following command in order to gather more information about the last known state of the container and for the associated exit code. Docker exit codes are based on the chroot standard.
kubectl describe pods [podname]Doing a "kubectl describe" should provide you more information as to why your pods got terminated.
This could be a kubernetes bug as mentioned here - https://github.com/kubernetes/kubernetes/issues/51376
Although this issue is closed as of now, I would suggest you to try running the same daemonset in default namespace. Even I tried running it in kube-system namespace but its failing and was running successfully in the default namespace.
