Inotify events not triggering under /Users

Docker Desktop for Mac
1

Expected behavior

Changes to files under /Users on MacOSX should trigger inotify events observable inside container using inotifywait from inotify-tools ubuntu package.

Actual behavior

No events are triggered. However, when mapping /tmp, the events are propagated and can be observed using inotifywait.

docker run -it -v /tmp:/mnt/tmp -v /Users:/Users ubuntu:16.04 bash

Steps to reproduce the behavior

  1. Create the container using command above
  2. Install inotify-tools inside container
  3. Listen for events using inotifywait -rm <file_or_folder>
  4. Create or modify files under /tmp and under /Users on MacOSX
  5. Observe that events are received in container for changes under /tmp; but not received for changes made under /Users

UPDATE: This morning I was testing whether file permissions or ownership on /Users would make a difference and I was both restarting the Docker app and recreating test containers when suddenly notifications started coming through. I’ve restored file permissions and ownership on /Users but the notifications are still working.

At this point I’m unable to reproduce the issue. I am guessing restarting the docker app fixed the issue. Will post further updates if I see the issue again.

UPDATE: Notifications suddenly stopped after working well for a few hours. Restarting container and restarting docker app did not help. However, recreating the container made notifications work again!

inotifywait doesn’t work for me either even though I didn’t use the symlinked /tmp.
docker run -it -v /private/tmp/:/mnt/tmp ubuntu:16.04 bash

I’m having the same issue with inotify not triggered in mounts under /Users:

Here is some more information:

I am trying to run an app via pm2 with the following configuration:

# process.yaml
apps:
  - name: api
    script: api/index.js
    instances: 1
    exec_mode: fork
    watch: true
    ignore_watch: [".git", "node_modules"]
    watch_options: 
      polling: true

Any changes I make to api/index.js doesn’t cause a restart. Oddly enough, if I remove the .git directory from the ignore list, pm2 reloads perpetually indicating that changes are detected on .git/index.lock

I also tried running inotifywait -r -m on api/index.js and it doesn’t report any changes when I modify them from within OS X.

The command is docker run -v .:/opt/app <my-app>:latest pm2 process.yaml (somewhere under /Users/bez/)

Here is the result of diagnostics:
