Chapter 4 Lab 4.2 Exercise 5

All, I am working in chapter 4 lab 4.2 working with cpu and memory constraints. I am currently on number5 in the lab and the kubectl replace -f hog.yaml is generating an error and it says :Error from server (NotFound): error when replacing "hog.yaml": deployments.apps "hog" not found and per the lab it is supposed to say : deployment.apps/hog replaced. Am I running the command correctly? I would think that you need to tell the operating system were the file is you want to replace? it does not. I lokked it up too and it seems it was typed in correctly per the lab? I am typing in kubectl replace -f hog.yaml, It is worded exactly how it is in the lab. I also tried tab completion per a prior lab. is the command incomplete? I will move on...But, i am curious how to run the command. Or what the problem is?

Now I am in chapter 7 labs and I am trying to issue the command : kubectl describe rs rs-one. amd it is telling me the error. Error from server (NotFound): replicasets.apps "rs-one" not found. everything else is gettibng created and it looks like the printout in the lab sheet. I can't seem to find yaml files. I am doing something wrong. Can you see what that is. right now everything is going good except for finding these type of files. One more question i have is ? are all of these commands complete or are they designed to make us try and figure this out.

I left everything in one thread because I think i forgot something somewhere. That is why I think i am getting the can't find error a lot. Now I can,t delete the replicaset I created in chapter 7 as well.

Maybe I am not entering the command in correctly. I will look at the video again so I can check. I also wanted to ask you guys. I know what you guys are going to say LOL! I know i entered the commands in a lot. I was seeing about the syntax.0 -
Hi @dctheroux,
Ensuring that you run syntactically correct commands is important, but interpreting the feedback from the CLI, generated after you run a command, is equally important.
It seems that you keep getting "not found" feedback messages when you attempt to delete objects. That indicates that you are trying to delete non-existing objects. Did you delete them previously? Were you able to successfully create the objects in previous steps? Were you able to verify the objects were generated and they are in an expected state (typically with a
kubectl get
command to list objects of a specific type, andkubectl describe
command to list individual object details)?Regards,
