Not sure if the nginx image is the best choice for all scenarios, though.

I believe I have to use `nslookup` for both the service and pod, but I can't recall if I need to specify any flags or options when running the command.

I'm a bit confused about the DNS records part. Do I need to check the service and pod names exactly as they are defined in the deployment?

I practiced a similar question last week, and I think I need to use `kubectl expose` to create the service after the deployment.

Alright, let's do this. I'll start by creating the deployment and service, then use nslookup to verify the DNS records. Gotta make sure I get those file paths right though.

Okay, I think I've got a plan. First I'll create the deployment and service, then use nslookup to check the DNS records and write the output to the specified files. Shouldn't be too difficult as long as I remember the right commands.

Hmm, I'm a bit unsure about how to set up the DNS records for the service and pod. I'll need to review my notes on Kubernetes DNS to make sure I do that part correctly.

This looks like a pretty straightforward deployment question. I'll start by creating the nginx-random deployment and service, making sure the container uses the nginx image.
