no automatic restart when using boot2docker docker volume

[chrishiestand]

nodemon doesn't seem to restart node when using a docker volume, or in this case a boot2docker ( os x -> virtualbox -> docker) volume. nodemon starts okay, but then fails to restart node when a watched file has been modified in the shared OS X volume.

nodemon -L causes restarts at least once a second even when no files have changed - way too frequently.

forever -w seems to work just fine. That seems like the best workaround for now.

output of dump:

When I use boot2docker with my branch off of library/node, when I try to use nodemon /path/to/app --watch, the cpu goes nuts like it is constantly restarting, although I can't verify.

I tried -L, but it also caused the CPU to go nuts.

I changed to pm2 for now, but it has 2-3 seconds of delay before it restarts. Still, better than nothing.

+1 this happens to me as well with a mounted volume on boot2docker (OSX + VirtualBox).

I'm marking as "help wanted" - I don't have the infrastructure to even begin testing and debugging this.

I'm sure it's linked to clocks being out of whack somehow, but can't replicate myself with simple tests.

[tanis2000]

@remy if I can help you in any way, just let me know what I should do.

[remy]

@tanis2000 if you can pull the project inside of your virtual machine. I'd start by trying to discover why -L sets the CPU insane. The watching logic is all in watch.js - it's a little complicated because there's multiple methods to actually watch.

Really you want to get a handle on what's causing the issue in the first place. I usually console log the crap out of the code when I'm spelunking for errors.

still not seeing an automatic restart with a volume mounted nodejs project in b2d

[mrmurphy]

Remy, thanks for nodemon. Did you close this issue because you resolved it? Or did you not have enough helpful feedback to fix?

We've been experiencing the same problems as mentioned above.

[remy]

No, it looks like it was closed by mistake in the associated PR. I'll reopen and ask for help (from you lot!).

[remy]

If anyone wants to push a Docker image that I can test and debug this with – I'd be grateful.

👍 same problem here
