Bark Server self-host

Out of the goodness of their heart, github user Finb gave us three things:

• the bark ios app
• the bark apn server
• their private key that authenticates to the Apple Push Notification (APN) service

The bark server provides an api to push notifications to ios devices it knows about. It can be as simple as a docker container. [Build it yourself][0] or pull it from docker hub.
