@aveshagarwal FYI

node's CPU and memory allocatables

It was changed in kubernetes/kubernetes#29639 and I also sent a doc update PR here:
https://github.com/kubernetes/kubernetes.github.io/pull/1107/files

@aveshagarwal I had to Google why Atom didn't like it, but it turns out allocatables is not a word... So I changed to "allocatable values".

[aveshagarwal]

Fine with me.

[bfallonf]

@aveshagarwal I've made the changes as per your suggestions. I'll presume everything else is OK and move forward, but please let me know if there's any other issues with this. Thanks!

@adellape @ahardin-rh @tpoitras Probably OK for peer review please!

This is not correct for the volume example above.

[bfallonf]

@aveshagarwal OK. I removed this step.

[ahardin-rh]

@bfallonf just a few style nits from me. Other than that, looks good! 🌟

Thanks @ahardin-rh and @aveshagarwal Suggestions put in. I'll merge away.
