I have no idea how to actually deploy anything yet. This is all taken from Getting Started, read that to make sense of this. This is really just meant to be notes as a kind of a quick start.

The point:

So I have been dicking around with Elixir for a while. Really enjoying it. However I have never taken the time to actually attempt to build a service that is deployable. So have decided to build up a minimum app that demonstrates a service that has the basics that a deployable app would have.

The goal is to have a service that

  1. can restart a part if it fails (supervisor hierarchy)
  2. has logging
  3. is testable
  4. can be deployed
  5. can demonstrate distributed processing with location transparency.
  6. Has a way to communicate with external world.

Steps to build

  1. mix new kv_umbrella --umbrella - creates the umbrella project
  2. build the service and the client projects 
    $ cd kv_umbrella/apps
$ mix new kv_server --module KVServer --sup
$ mix new kv --module KV
  3. mix test - all should compile tests should run.
  4. …
  5. wip
  6. profit

How to deploy?

  1. exrm - generates a package including erlang. It appears like you stick it somewhere and start / stop the service.
  2. edeliver - based on deliver - a bash tool. Get it here
  3. Good youtube talk
