title: Building a iOS app with Fastlane inside Docker
body: <p>I'm trying to streamline my iOS development builds and read about Docker.</p>
  
  <p>If I understood it right, I could create an image that would include all the dependencies and my fellow devs could just pull it and build inside it.</p>
  
  <p>Point is now, does this also work with Fastlane (which uses the Xcode cli tools I think) and "Docker for Mac"?</p>
  
  <p>Also, I'm using React-Native, which seems to start a second process for bundling the JavaScript that will be included in the <em>native</em> build later and I read Docker only allows one process, is this a problem?</p>
