How can I run a method in a subprocess in golang?

[ggyft]

My use case is that I am designing a scheduler that schedules various health checks (go method) periodically. Earlier I want to model run them in a new goroutine. But I ran into problems when I want to design timeout for each method. Basically go seems not able to kill goroutine and clean up resources like socket etc.

I am wondering rather than run method in goroutine, can I run it in subprocess so I can kill it safely? My platform is windows hope that doesn't matter.

Rather than thinking about it as a lack of having a first class kill command for goroutines, you need to run your goroutines in a way that the work can be stopped. This can be accomplished with a Context that can be closed or times out, or a channel that receives a stop signal, or even an atomic that can be checked periodically. The work within the goroutine has to be aware of stop conditions.

There is nothing stopping you from running health checks as separate command as long as you have something to call.
