Today in "weird shit Kubernetes does": did you know that if you try to do an in-place resize for a pod, the result can be one of three states?

Those states are "yes, did it", "nope, sorry, can't fit", and "well it can't fit RIGHT NOW, but it might fit sometime in the far distant future, so I'm just gonna sit here forever and hope" (The technical term for the last state is "Deferred", in case you're curious)

In this case, your pod might try to resize up, but all the other pods on the node are being greedy jerks and hogging all the resources, so kubelet's like "Welp I'll just wait for everyone else to stop being a greedy jerk 🤷"

Hey kubelet, lemme give you a clue! The other pods aren't going to stop being greedy jerks! Like, ever!

Anyways, I guess this is just yet-another reason why you should always set requests=limits.
