<p>Can anyone please help to debug this. Thanks in advance!</p>

<p>This could be a kubernetes bug as mentioned here - <a href="https://github.com/kubernetes/kubernetes/issues/51376" rel="nofollow noreferrer">https://github.com/kubernetes/kubernetes/issues/51376</a></p>

<p>Although this issue is closed as of now, I would suggest you to try running the same <code>daemonset</code> in <code>default</code> namespace.
Even I tried running it in <code>kube-system</code> namespace but its failing and was running successfully in the <code>default</code> namespace.</p>
