I've found #383 and #461. Is it possible at this time to deploy storage rules using CLI? If yes, how? Is it documented somewhere?
firebase init storage
After set up is complete:
firebase deploy
OR
firebase deploy --only storage
I've also filed a bug internally to update our documentation with these instructions.
Documented in the getting started for Storage Rules, as well as an in-depth look at deploy targets if you're doing multi-bucket.
