<p>I am trying to debug my pod throwing CrashLoopBackOff error. When I run decribe command, I found that <code>Back-off restarting failed container</code> is the error. I excuted the logs for the failing pod and I got the below data.</p>
<pre><code>vagrant@master:~&gt; kubectl logs pod_name
standard_init_linux.go:228: exec user process caused: exec format error

vagrant@master:/vagrant&gt; kubectl logs -p  pod_name
unable to retrieve container logs for containerd://db0f2dbd549676d8bf1026e5757ff45847c62152049b36037263f81915e948eavagrant
</code></pre>
<p>Why I am not able to execute the logs command?</p>

<p>Any help is appreciated.</p>

<p>Summarizing the comments: <code>CrashLoopBackOff</code> error occurs, when there is a mismatch of AMD64 and ARM64 devices. According to your docker image <code>udacity/nd064-udaconnect-app</code>, we can see that it's <a href="https://hub.docker.com/r/udacity/nd064-udaconnect-app/tags" rel="nofollow noreferrer">AMD64 arch</a> and your box <code>opensuse/Leap-15.2.x86_64</code> is <a href="https://en.opensuse.org/openSUSE:AArch64" rel="nofollow noreferrer">ARM64 arch</a>.</p>
<p>Hence, you have to change either your docker image, or the box in order to resolve this issue.</p>
