I thought we were supposed to avoid using environment variables for secrets?

Just make sure to use the right container image, nginx is perfect!

Wait, can you really expose secrets like that? Seems risky.

You need to create a secret named another-secret with key1/value4.

Haha, I bet the exam writers had a good laugh coming up with "COOL_VARIABLE" as the environment variable name. Gotta love those creative touches!

Option C looks good, but I'm still a bit confused about the environment variable name. Shouldn't it be something more descriptive?

The correct answer is C. That's the easiest way to create a secret and consume it in a pod.

I definitely recall the steps for creating a pod, but I’m uncertain if I need to specify the secret in the pod definition or just in the environment section.

This question seems similar to one we practiced where we had to expose a config map as an environment variable. I hope I can apply that knowledge here.

Ah, I see what I need to do now. I'll create the secret first, then in the pod definition I'll use the `env` field to reference the secret value by its key. Simple!

I'm a little confused about the difference between the `env` and `envFrom` fields in the pod definition. I'll need to double-check the documentation to make sure I'm using the right one for this task.

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

No problem, I've done this kind of task before. I'll use the `kubectl create secret` command to create the secret, and then in the pod definition I'll use the `env` field to expose the secret value as an environment variable.

I feel a bit confused about the naming conventions for the environment variable. Was it COOL_VARIABLE or something else?

Hmm, I'm a bit unsure about how to create the secret and then reference it in the pod. I'll need to review the syntax for that.

Okay, this looks straightforward. I'll start by creating the secret with the key/value pair, then I'll create the nginx pod and add the environment variable to expose the secret value.

And for the pod, you'll use `kubectl run` with the right flags, right?
