Why doesn't it exist on Heroku?

I want to use Akka and a distributed queues system for actors to communicate on different dynos. RabbitMQ doesn't seem to be the best option using Akka, because a lot of tricks are needed to seamlessly work with actors without concerning about the underlying queues.

Nevertheless, the best option seems to be Durable Mailboxes but with RabbitMQ: akka-amqp-mailbox. I still have to set it up first though.

What other options do you consider that provide a seamless underlying queues system on Heroku with Akka?

Thanks!

You can use Heroku Vulcan to build and run it yourself. This is what I do whenever I run into something that Heroku doesn't support OOTB. And, "why doesn't it exist"? Because you haven't built it yet! ;-) Good luck.

  • I managed to build it after applying this hack (https://github.com/heroku/vulcan/issues/51), but I don't know how to use the result. This tutorial (http://goo.gl/S0WaW) says we should vendor the app, but I can't find an bin/executable to run it and thus start the server. Any help would be appreciated. – Marius Stroe May 06 '13 at 22:58
  • You can "use" it by incorporating it into a buildpack, or by pulling it in during boot (as in, have your Procfile run a script that downloads the binaries produced from your vulcan build) – Travis Webb May 06 '13 at 23:26
  • Do you happen to have a reference to a tutorial / doc doing it? I couldn't find something to help. – Marius Stroe May 07 '13 at 10:27

You can use the official Heroku APT buildpack to install zmq to your Heroku app.

Steps:

1) Add https://github.com/heroku/heroku-buildpack-apt as a buildpack. Make sure it is added above/before build packs such as heroku/nodejs so dependencies can be met.

2) Add Aptfile file into the root of your repo with this content: 

libzmq3-dbg
libzmq3-dev
libzmq3

3) Deploy
