What Hacker News says
6 sourcesSomeone did this for golang. It isn't perfect, but works for some basic use cases... https://github.com/jpillora/overseer
In Upgrading Executable on the FlyI deployed a binary golang agent [1] across about 2000 raspberry pi class machines (for litecoin mining) using overseer [2].
It allowed me to implement zero downtime upgrades, which was pretty cool. Internally within the agent, I used the context pkg to implement with a 'Manager' which provided cron like functionality where each thing could be shutdown gracefully [3]. Used the same mechanism to shut the internal webserver down gracefully as well [4].

In Graceful ShutdownThis is an excellent write up, very easy to follow. Overseer [1] is a pretty good implementation as well.
"Commonly, graceful restarts are performed by the active process (dark blue) closing its listeners and passing these matching listening socket files (green) over to a newly started process. This restart causes any foreground process monitoring to incorrectly detect a program crash. overseer attempts to solve this by using a small process to perform this socket file exchange and proxying signals and exit code from the active process."
