integrate mobile app

[bodymindarts]

Primary desired outcome is
a)

• document known good combination of releases for our entire stack (includes mobile)
  -> versioned mobile release
  • include automated release notes generation
  • GitHub release
    -> pin the release together with the versioned backend stack

b)

• release process is automated end-to-end and reproducible without specific knowledge

Secondary task
a)

• evaluate pain points of mobile app releasing
  -> consider best long term releasing strategy (given needs of ^^^)
  -> conclude to redesign parts / all / none of the existing setup
  b)
• develop boilerplate / scaffolding to hook in e2e tests (probably against staging)

Current pain points:

• custom knowledge required
• hard part is not creating the APK -> managing the phased roll out

Open Questions:
separate versions for android, iOS, Huawai?

Can release description be tied to conventional commits?
-> probably simply generic description

Leverage fast lane

Additional thoughts:
OS builds are free <- biggest reason not to migrate to concourse
Ideally we decouple the scripting from circle ci (so we could move around)
