Ruby 上帝-在现有进程仍在停止时启动新进程
使用God(godrb.com),我试图编写一个配方,在部署应用程序时,无论现有进程的状态如何,都可以启动一个新进程。现有进程需要较长的运行超时才能完成当前任务,但新进程应该使用新部署的代码立即启动 我现在设置了一个300秒的停止超时时间,但是在启动新进程之前要等待整个300秒Ruby 上帝-在现有进程仍在停止时启动新进程,ruby,monitoring,god,Ruby,Monitoring,God,使用God(godrb.com),我试图编写一个配方,在部署应用程序时,无论现有进程的状态如何,都可以启动一个新进程。现有进程需要较长的运行超时才能完成当前任务,但新进程应该使用新部署的代码立即启动 我现在设置了一个300秒的停止超时时间,但是在启动新进程之前要等待整个300秒 God.watch do |w| w.name = "sidekiq" w.interval = 30.seconds w.start = "bash -lc 'cd /path/to/current &am

end
在本例中,kill-USR1
告诉sidekiq完成处理任何当前作业,但不再进行任何工作
我希望保留现有工作进程的300秒超时,但在kill命令运行后立即启动新进程。我认为您必须定义一些转换 这是我的上帝

你看过独角兽是怎么做到的吗?这使得独角兽有责任培养新员工,并让这些新员工杀死旧员工。是的,但这一功能是独角兽的一部分。我正试图用任何通用的过程来完成类似的事情。
