How can I make sure distillery includes Erlang inets in the release?

My application, when trying to run a release, has this fatal issue:

** (MatchError) no match of right hand side value: {:error, {:inets, {'no such file or directory', 'inets.app'}}}

It works fine when running it with mix on my localhost, however the distillery 2 release has this issue.

I installed erlang-inets ubuntu package from the erlang solutions repo and did another mix release, but that didn't seem to fix it.

What am I missing?


  • You need to instruct mix to include inets OTP application into the release. In your mix.exs:

    def application do
        mod: {MyApp, []},
        applications: [:logger, ..., :inets, ...]

    Sidenote: erlang-inets has nothing to do with the issue.
