I thought pod-2 was using more resources, but I guess not!

Just checked, it's definitely pod-1 that's hogging the CPU.

The pod with the highest CPU usage is usually the one under the most load.

This seems similar to a question about resource limits we did in class. I hope I can remember how to redirect the output to the specified file correctly.

I feel like I should be able to use `awk` or `sort` to find the pod with the most CPU, but I can't recall the exact command syntax.

I remember a practice question where we had to write output to a file, so I think we might need to use `kubectl get pods` with some flags to get just the name.

I think we need to use `kubectl top pods` to check the CPU usage, but I'm not entirely sure how to filter for the highest one.

Okay, let's do this. I'll need to find a way to get the CPU usage for each pod and then identify the one using the most. Hopefully, I can do that without too much trouble. Gotta make sure I write the name to the right file.

Alright, time to put my Kubernetes skills to the test! I'll start by listing the pods in the 'cpu-stress' namespace, then use a command to sort by CPU usage and grab the name of the top one. Shouldn't be too tricky if I remember the right commands.

Hmm, this seems straightforward enough. I'll need to use some kubectl commands to get the pod information and then write the name of the highest CPU consumer to the specified file. Gotta be careful with the syntax though.

Okay, let's see. I'll need to find the pods running in the 'cpu-stress' namespace and then identify the one consuming the most CPU. Shouldn't be too difficult, just need to stay focused.

I hope the pod name isn't something like 'cpu-hogging-monster' or 'I-need-more-cores'. That would be too easy, right?
