Wait, does that actually work for all namespaces?

Just use `kubectl get pods -n development -l app=baz` to list them.

I thought we needed to specify the service name too?

I think we might need to use `kubectl get pods --selector` to filter by the service, but I can't recall the exact syntax.

I feel a bit lost on how to specify the namespace in the command. Is it `-n development` or something else?

I remember practicing a similar question where we had to list deployments. I think we might need to use `-o name` or something like that to get just the pod names.

I think we need to use `kubectl get pods` with some flags to filter by the service, but I'm not entirely sure how to format the output.

This is a good opportunity to practice my Kubernetes skills. I'll take it step-by-step and make sure I get the file created correctly.

Wait, do I need to use `kubectl` or can I just use standard Linux commands to create the file? I'm a bit confused about the requirements here.

Okay, I think I've got this. I'll use `kubectl get pods -n development --selector=app=baz` to list the pods, then redirect the output to the file at the specified path.

Hmm, I'm not sure how to create that file in the specified location. I'll need to look up the commands for that.

This looks straightforward. I'll start by checking the pods in the development namespace and filtering for the ones that implement the baz service.

Haha, this reminds me of that time I accidentally deleted the entire 'development' namespace. Not making that mistake again!

Ah, I see. So we need to create a file with the list of pods that implement the 'baz' service in the 'development' namespace. Sounds good, I'm on it!

Yes, we can use the kubectl command to get the pods and then filter by service.

This seems pretty straightforward. I'd use the `kubectl get pods -n development --selector=app=baz -o name` command to get the list of pod names and then write them to the file.
