Can I run the client as a docker image but not running K8s? For example, I would like to add my Austor NAS to the mesh. It supports running containers but it's not a full Debian OS.

yes, you can run the docker client anywhere

Cool. Where are the docs for setting that up? I didn't see it in the client docs page.

when you create an access key, it will display instructions for running the docker netclient

I thought I saw that somewhere, lol! Thanks!

keep in mind, if you're running into trouble with the gravitl/netclient image, you may want to try the gravitl/netclient-go image, which contains userspace wireguard

Ok. And I'll need the ARM image as well. I'll take a peek at it.

i believe it should be multi-arch but I know someone else had issues on arm a while back...

only arm64, though arm7 can be build with small change to dockerfile

It's ARM64. The regular one runs but won't route traffic. Trying the userspace one.
