Deploying a web app to Kubernetes with SSL using Let's Encrypt via cert-manager and nginx-ingress

Spin up a Kubernetes cluster

You can do this with MiniKube for development and testing, or Google Cloud's GKE for the real thing.

This short code will show how to sync database file using Realm, but can be used for any file that you need to send to Wear (using Data API). It just takes any file, change it to Asset object and send it over to Wear device. Also it can be used Mobile->Wear, and Wear->Mobile.

When you need to sync database just call FileSender.syncRealm(context);, that is it!

DISCLAIMER "Proper" way would be to synchronize each transaction to DB, but it in most cases Wear is used very rarely comparing to mobile, so it would most likely cause a battery drain. My idea was to synchronize it only whene it is needed (so for example when app closes). If you want to make sure that you are using latest DB, just send trigger data using MessageAPI from Wear to Phone with ask of syncing over its database, or keep some timestapm of last edit and check it.
