I think we can use 'echo' command to write the pod name to the file.

Wait, we have to write the pod name to a file? I was just going to print it to the console. I hope the file has the proper permissions, or this is going to be a real headache.

This is a piece of cake! I bet the high CPU pod is running a cryptocurrency mining operation. *wink wink*

Once we have that information, we can write the pod name to the specified file.

The solution looks good, but I'm wondering if we need to handle any edge cases, like if there are no pods with the 'name=cpu-utilizer' label or if the target file doesn't exist.

We can also add a check to see if the target file /opt/KUTR00401/KUTR00401.txt exists before writing to it.

We should add some error handling to check if there are no pods with the 'name=cpu-utilizer' label.

This question seems straightforward. The key is to use the 'kubectl top' command to find the pod with the highest CPU usage from the pods with the 'name=cpu-utilizer' label, and then write the name of that pod to the specified file.

After finding the pod, use 'echo 'pod name' >> /opt/KUT00401/KUT00401.txt' to write the name to the file.

Use 'kubectl top -l name=cpu-user -A' to find the pod with high CPU usage.
