Ah, I see the discussion thread on Discord, thanks.

It looks like you encountered a gap in the Dockerfile compatibility bridge, specifically lack of support for `--mount=type=ssh` [1]. It's true that our Dockerfile compat layer has more gaps than the native Dagger API itself. In effect, beyond very simple Dockerfiles, to get the full benefit of Dagger you need to convert them to code targeting the Dagger API. While there are many benefits to this, it does add significant friction to getting started.

It seems like we need to beef up our compatibility story!

Thanks for taking the time to share all this feedback, and sorry again that your experience didn't work out.
