restartable-server

Implementation of a HTTP server resilient to SIGTERM OS signal and restartable on demand.

Especially interesting when deploying HTTP servers with the GO runtime in containers.

Container runtime engine usually send a SIGTERM signal to kill the server process, which can be catch by the restartable server to restart itself.

Provided as Proof of Concepts. Currently available at restartable-server.heroku.com.
