This is great - thank you!

We have currently not provided a Dockerfile in the docs so far with the aim of instead providing a Docker preset that could even generate a file for users. unjs/nitro#54. @pi0 would be better able to comment, but it's possible we might defer adding this to the docs until we have a first-class nitro docker preset.

In terms of feedback on the Dockerfile, I would also advise not including the ~/node_modules folder in the image but only ~/.output as it should have all its dependencies already installed there.

I commented on the dependency file. There may be users who want to use it. By default, no dependent files will appear. is used ~/.output file

Thanks for PR @516310460 <3 As daniel mentioned, we might introduce docker preset with proper nitro support, multi-stage build and only including .output.
