Context: I have a nextjs application which is really good at hot-reloading. I'd like to have a docker-compose like experience with the database, via Dagger, so run the nextjs app in dev mode in Dagger, expose the port for browswer preview, attach the database as a service.
Is there a way to get host directory changes to be reflected in the one mounted into the nextjs container?

AFAIK not possible in dagger v0.6.4. Not sure if Zenith will enable some of this. cc @main nymph.

I wonder if something of a hack could be done with a shared cache again 
late osprey
problem is host <> dagger sync.. since Dagger / Buildkit is designed to be share-nothing as it's designed to be able to be fully deterministic to work remotely
my best guess is that something would be possible by rsyncing the contents over a unix socket somehow.. but seems like a very hacky alternative

sounds like a fun experiment! a shared cache volume + a container syncing over a socket somehow should do the trick. might be easier with h2c/c2h networking.
(ideally this would just be a first-class feature so you don't need that of course)

yeah, I was thinking of using our Watch with debounce and have it write whatever to the shared cache, at which point, the nextjs should see it
(https://github.com/hofstadter-io/hof/blob/_dev/lib/watch/watch.go)
though we probably need a version that passes the event through, so that we can see what changed and how, and then make the mirroring action

@rich escarp curious if you got this working? Or if there's a dagger issue to follow... Thanks!

I never tried to implement it
