Create a deployment as follows:

Name: nginx-random

Exposed via a service nginx-random

Ensure that the service & pod are accessible via their respective DNS records

The container(s) within any pod(s) running as a part of this deployment should use the nginx Image

Next, use the utility nslookup to look up the DNS records of the service & pod and write the output to /opt/KUNW00601/service.dns and /opt/KUNW00601/pod.dns respectively.

Make sure to check the DNS records after!

Wait, do we really need to write the output to those specific paths?

I thought nginx was just for web serving, not for DNS stuff too?

I feel like I’ve seen this setup before in our labs, but I’m not 100% confident about the deployment name needing to match the service name exactly.

I definitely need to check the DNS records with nslookup, but I'm a bit confused about where to write the output files. Is it really /opt/KUNW00601?

I practiced a similar question where we had to expose a service, but I can't recall if I need to specify the type of service for this one.

I think I remember how to create a deployment, but I'm not entirely sure about the exact command syntax for the nginx image.

Okay, let me think this through step-by-step. First, I'll create the deployment with the nginx image. Then I'll create a service to expose it. Finally, I'll use nslookup to verify the DNS records. I think I can handle this, but I'll double-check my work to make sure I don't miss anything.

No problem, I've done this kind of thing before. I'll create the deployment, expose it with a service, and then use nslookup to check the DNS records. As long as I follow the instructions carefully, I should be able to get this done quickly.

Hmm, I'm a bit unsure about the specifics here. I'll need to review the Kubernetes documentation on deployments and services to make sure I'm doing this correctly. Hopefully I can figure it out in time.

This looks like a straightforward deployment task, but I'll need to be careful to get the details right. I'll start by creating the deployment and service, then use nslookup to verify the DNS records.

The containers in the pods should use the nginx image, right?

This question is a good test of our Kubernetes knowledge. I'm confident I can nail this one, as long as I don't accidentally deploy a pod that runs on Internet Explorer. That would be a real disaster!

Haha, I bet the exam proctors will be impressed if we include some witty comments. How about this one: 'Hey, at least they didn't ask us to create a deployment for a web server that serves cat memes!'

Using 'nslookup' to write the DNS records to the specified paths is a nice touch. Seems like a straightforward solution to me.

The deployment name, service name, and container image are all specified correctly. This should work as expected.
