Phoenix: [error] backend port not found: :inotifywait

[jhlllnd]

I get the message

[error] backend port not found: :inotifywait

when running mix phoenix.server

I think i am missing something but i can't find something about phoenix and inotify or inotifywait on google or in the docs. Maybe it has something to do with code reloading?

Edit:
I have Elixir 1.0.3 and phoenix 0.11

Yes! You need that for live reloading, we need to make the docs/guides better. Install instructions here:

I can improve phoenix_live_reload readme but I am pinging @jeregrine @lancehalvorsen to let them know and figure out if something needs to be done in the guides front.

Thanks, that was what i needed to know :)

@josevalim Having just hit the issue on my linux install, seems the inotify instructions should also be on the installation page, not just the overview page, no?

Ok, that's great; but how do I just turn inotifywait off? What if I don't need it? What if the error shuts down a dockerized phoenix container I am trying to run?

[josevalim]

@twajjo it shouldn't shutdown a phoenix container and it is used only in development. If you don't want it at all, remove phoenix_live_reload as a dependency and from your endpoint.ex.

[twajjo]

Thanks, Jose. I agree that it should not shut down the phoenix container, and it does not if I use a shell entry point and start the server by hand, but (weirdly enough) it does. Still trying to figure out what the issue is.

[josevalim]

@twajjo are you setting MIX_ENV=prod when building and starting the app?

[twajjo]

Yes I am. The issue was a bad Dockerfile example provided by a co-worker. I have resolved the issue, but many thanks for your attention.

And many more thanks for my new favorite language, Jose.
