使用Go时在生产服务器上更新代码

Question

When I develop and update files on production server with PHP I just copy the files on the fly and everything seems to work without interrupting the server.

But if I am to update the code on the Go server and application and would need to kill the server, copy the src files to the server, run go install, and then start the server, this would interrupt the service, and if I do this quite often then it is going to look very bad for my users of the service.

How can I update files without the downtime when using Go with Go's http server?

The grace library will allow you to do graceful restarts without annoyance for your users: https://github.com/facebookgo/grace

Yet in my experience restarting Go applications is so quick, unless you have an high traffic website it won't cause any trouble.
