Hardware requirements for Certificate Manager

[suikast42]

I can't see any information hardware requirements of

1. CanIJector
2. Cert-Manager-Controller
3. Cert-Manager-Webhook

Can the documentation be improved on that?

Thanks for raising the issue!

I agree we could do a better job of documenting this kind of thing. I'm not sure we have much in the way of explicit numbers we could use to make hardware recommendations, but I'm sure it wouldn't be too hard to get some baseline numbers. If you'd be interested in contributing - either here or on the website - I'd love to see a PR!

Entirely anecdotally, I've run a small cert-manager installation successfully on a 1GB Raspberry Pi 3 using k3s, which is a pretty low-power environment to be running on. I suspect that in practice, any k8s clusters that are realistically run in production could run cert-manger without too many issues.
