File change anywhere in my file tree should trigger inotify event and trigger watchers in Container
Actual behavior
Some files, when saved, do not produce any notification to watcher

Steps to reproduce the behavior
I have been developing this app heavily using Docker for some months. I use a dev setup that involves an rsync based syncer to push changes from OS X into a docker-machine. With no changes, using Docker for Mac, I can get my app to boot (albeit much slower), but only the top level component of my React.js based application triggers the Webpack watcher. Deeper components when modified or saved do not.
If I switch back to my rsync + docker-machine based implementation, the watcher is triggered just fine.
If you have any suggestions on how I might be able to provide better debug info, let me know.
Does the directory hierarchy already exist in OS X when you bind mount it into your container? Does the path you are mounting have symlinks as any of the components? There is a known issue with bind mounts through symlinks that we have a patch for which should arrive in Beta 7.
If you aren’t watching through symlinks, we’ll need to dig deeper.
Thanks for participating in the Docker for Mac Beta!
Could you please post your unique error report identifier? It will enable me to pull your system logs from our repository to get an idea of what has gone wrong.
There is a known issue regarding event delivery failure. In particular, the path used to register for OS X file system events is not properly normalized. You could try restarting Docker and then using paths that 1.) don’t have symlinks 2.) have case matching the case stored in the OS X file system 3.) don’t contain ., .., or a trailing slash /.
We hope to have this known issue resolved soon.

Not sure if this is what you meant, but my diagnostic id is: 804F32D7-E6B8-4F1C-8CF0-7DA0F5B9202A. I’m not seeing a specific error, just that webpack --watch isn’t picking up filesystem events.
I just tried restarting docker and changing the casing (on OSX the project is saved as PaperBadger, and docker-compose.yml is configured to paperbadger). But that doesn’t seem to have fixed it. I’m fairly certain that no symlinks or filenames with those character are being used.
I have verified that inotify is working via inotifywait -r -m . from inside the container and then editing a file on the host (OSX). The changes are picked up right away.
If I run webpack --watch or other webpack variants from inside the container and edit the same mounted file, the changes are not picked up. I have tried with Chokidar which looks like the underpinning library that webpack uses and that doesn’t seem to be working either.
I used this option below to get webpack pickup changes:
watchOptions: {
poll: true
}
It works, but it seems to eat up all of the CPU and also the recompilation is slowed down (from 1s before to 5-6s now). Before I was using dinghy with unfs3.
