Current cuda, cudnn versions?

Apologies for the noob question. There are several related questions, but they seem out-of-date.

I’m doing ML with a non-conventional framework, and it didn’t work out-of-the box with Lambda because of CUDA version mismatch.

I need to recompile my ML framework to whatever version is the one lambda uses, hence my question: what is the current version, and is there a page listing the version numbers that I can refer to when versions change?

Even better if there is a corresponding NVidia docker that matches what is used in Lambda instances …

Many thanks in advance!
