I like what kube achieves, I don't like the power and memory hungry requirements of it, it seems ill optimized. A cluster with no pods uses 5%-15% CPU, that's a lot of electricity being used for nothing. It's really odd since Google claims to have green datacenters.

Does Google use carbon swaps to conceal their emissions? Maybe that's how they reconcile the difference. A quick search turned up this: https://www.greencentury.com/google-parent-alphabet-pledges-greater-transparency-on-use-of-carbon-offsets-after-green-century-shareholder-proposal-2/ https://www.greencentury.com/google-parent-alphabet-pledges-... Looks like a possible case of greenwashing to me.

  Google doesn’t use kubernetes to run anything production. They use Borg

  I got into an argument with someone at google who said they don't use carbon swaps and ended up pulling up a shareholder report that said they did. Google is real big on the greenwashing.

Google doesn’t run on Kubernetee.

I'm curious, are you seeing that on cloud instances, or what? My experience with bare-metal Kubernetes hasn't been that bad. On my home cluster with very underpowered J4105 CPUs, I get about 5% CPU usage on the master node at idle, and 2% on workers.

  People need to check their logs for any oddities more frequently. A lot of the setups I’ve seen have subtle misconfigurations that leak/busy loop resources needlessly

I'd bet you're running a "stacked" control plane and if you moved etcd off to its own machines you'd localize the churn to be that. Which, if correct, doesn't exactly refute your "kubernetes is power and memory hungry" claim but would more clearly distinguish why I had high hopes back in my earlier days of them offering pluggable KV stores so folks could make tradeoffs if etcd doesn't align with their goals and risks but as best I can tell they've declared it a non-goal

  That's part of what k3s does
