Files needed to deploy (build) an Elm app on zeit.co with now

When you try to deploy an Elm app built with Webpack to zeit.co you may wonder why the deployed app doesn't work while the build process shows no errors. However, in the browser console you might notice something like

Uncaught TypeError: Cannot read property 'embed' of undefined
    at Object.<anonymous> (main-afc54605910c3ef5ded5.js:1)
    at o (main-afc54605910c3ef5ded5.js:1)
    at main-afc54605910c3ef5ded5.js:1
    at main-afc54605910c3ef5ded5.js:1

(Chrome) or

TypeError: undefined is not an object (evaluating 'r.Main.embed')

(Safari).

When looking closer on the build log you may notice that the Elm compiler didn't yield a result:

>  [11] ./src/elm/Main.elm 0 bytes {0} [depth 1] [built]

The problem is actually that elm-make fails to run on the Alpine Linux of zeit.co and creates a core dump due to functions missing in the C runtime library. The best solution I found was to use a Dockerfile that selects a different Linux. Feel free to use the files in this repository and build your Elm apps on zeit.co :-).
