You can use `kubectl get pods -o=jsonpath='{.items[*].metadata.name}'` for just names.

I think we just need to list the names and namespaces, but I'm not sure if the expression is complete as it is.

I remember practicing a similar question, but I can't recall if we needed to include the brackets around the keys.

Wait, how do I format the JSON path expression again? I know it's something like .items[*]['metadata.name', 'metadata.namespace'] but I'm not 100% sure.

No problem, I've got this. The solution is to use the -o=jsonpath flag with kubectl get pods to return the fields we need.

Hmm, I'm a bit unsure about the exact syntax for the JSON path expression. I'll need to review my notes on that.

I think I can handle this one. The key is using the right JSON path expression to extract the name and namespace fields for each pod.

Is it just me, or does 'jsonpath' sound like the name of a hip new programming language?
