Totally agree, 5 seems low for our setup.

Wait, are we excluding tainted nodes? That changes things!

I think we need to write the output to a file using `echo` or something similar, but I’m not clear on the full command sequence.

I believe we can use a combination of `kubectl` commands and `grep` to get the count, but I might be mixing up the syntax.

I remember practicing a similar question where we had to count nodes, but I can't recall the exact command for excluding tainted ones.

I think we need to use `kubectl get nodes` to check the status, but I'm not sure how to filter out the tainted nodes.

This seems simple enough. I'll just run `kubectl get nodes` and pipe the output through `grep` to count the ready nodes, excluding the tainted ones. Then I'll use `echo` to write the result to the file.

Okay, I think I've got this. I'll use `kubectl get nodes -o wide` to see the node status, then count the ones that aren't tainted. Finally, I'll use `echo` to write the number to the file.

Hmm, I'm not sure how to check for tainted nodes. I'll need to look up the command for that. And where exactly do I need to write the output to?

This looks straightforward. I'll start by checking the node status with `kubectl get nodes` and filtering out the tainted nodes. Then I'll write the count to the specified file.

Okay, so I need to check the worker nodes that are ready, excluding the ones with the NoSchedule taint, and write the count to a specific file. Sounds straightforward enough.
