Phoenix Umbrella Prod Release Doesn't Start

One thing to keep in mind though is that in an umbrella you have to explicitly include your umbrella children in the list of applications given to the release.

Thanks @josevalim! That was the root of the issue. I took this portion of the docs too literally:

[
        include_executables_for: [:unix],
        applications: [runtime_tools: :permanent]
      ],

I mistook runtime_tools for a config option instead of being the name of the app to include in the release. Once I replaced it with my apps actual name it worked. I really appreciate the help!
