芹菜工作人员如何优雅地重启？ [英] How do I restart celery workers gracefully?

问题描述

在发布新版本以更新工作人员的代码时，如何优雅地启动芹菜工作？

While issuing a new build to update code in workers how do I restart celery workers gracefully?

编辑：
我打算做的是这样的事情。

What I intend to do is to something like this.

• 工作人员正在运行，可能是将一个100 MB的文件上传到S3


• 新的构建来自


• 代码有变化


• 构建脚本向工人发送信号


• 使用新代码启动新员工

• Worker is running, probably uploading a 100 MB file to S3
• A new build comes
• Worker code has changes
• Build script fires signal to the Worker(s)
• Starts new workers with the new code
• Worker(s) who got the signal after finishing the existing job exit.
