I thought you could run multiple containers in one pod? Confused!

Classic mistake, but the YAML looks good otherwise!

Wait, why is consul in there? That wasn't mentioned in the task.

Totally agree, it should be separate pods for each container!

Just a heads up, you can't run more than one image in a single pod like that.

I think I need to double-check the indentation in the YAML file. It’s so easy to mess that up and cause errors when creating the pod.

I feel like we did a similar question in class, but it only had one container. I hope I can remember the syntax for multiple containers correctly.

I think the command to create the pod is right, but I’m a bit confused about the order of the images in the spec section. Does it matter?

I remember we practiced creating pods with multiple containers, but I’m not sure if I need to specify the ports for each container in the YAML.

No problem, I've done this kind of thing before. I'll just create the YAML file and apply it, easy peasy.

Wait, does the order of the containers matter? I better review the instructions again to make sure I get this right.

Okay, I think I've got a plan - I'll use `kubectl run` to create the pod and then edit the YAML file to add the additional containers.

Hmm, it says there can be between 1 and 4 images, so I'll need to double-check the requirements carefully.

This looks straightforward, I'll just need to create a pod with the specified images and names.

This is a tricky one. I'm not sure if we're supposed to count the number of dataflows that exceed a limit, or if there's some other criteria we need to consider. I'll need to read through the question carefully and make sure I understand what they're asking.

This seems like a pretty standard Java question. I'm confident I can figure out which code fragment will give me the Filechannel object I need.

I think the answer is Scalability. The question mentions the retailer needs a solution to handle high load during the holiday season, and Scalability seems like the best option to handle that.
