GAE Python - 如何设置cron作业以启动后端任务 [英] GAE Python - How to set a cron job to launch a backend task

问题描述

我在GAE上执行每日报告任务，因为最近使用的内存太多。因此，我想将其设置为后端任务。我已设置后端如下：

 后端：
  -  name：reporting 
 class：B4_1G 
选项：dynamic 
 start：reporting.app 
  

是定义的多个类，它们调用不同的报告。我的cron.yaml目前看起来像这样：

  cron：
  -  description：update report 1 
 url ：/ reports / report1 
日程安排：每天03:00 
  - 描述：更新报告2 
 url：/ reports / report2 
日程安排：每天03:30 $ b $但是在逻辑上，这只是通过app.yaml调用前端实例上的作业，目前看起来像这样： 
  
 
 
  application：appname 
 version：1 
 runtime：python27 
 api_version：1 
 threadsafe：true 
 
处理程序：
  -  url：/(robots\.txt）
 static_files：\1 
上传：（robots\.txt ）
  -  url：/favicon\.ico 
 static_files：favicon.ico 
 upload：favicon\.ico 
  -  url：/sitemap\.xml 
 static_files：sitemap.xml 
 upload：sitemap\.xml 
  -  url：/ images 
 static_dir：images 
  -  url：/ js 
 static_dir：js 
  -  url：/ css 
 static_dir：css 
  -  url：/reports/.* 
 script：reporting.app 
 login：admin 
  
我需要更改什么才能在后端实例上每天调用这些作业？
解决方案
更简单的方法是将应用程序迁移到模块。此处解释： https://developers.google.com/appengine/docs/python/modules /  
 
 
 
这样做后，您可以在cron.yaml中添加以下行：
  target：yourmodule 
  
在yourmodule.yaml 
 
中定义的实例
I'm running a daily reporting task on GAE which since recently is using too much memory to finish. Therefore I'd like to set it as a backend task. I've set the backend as following:
backends:
- name: reporting
  class: B4_1G
  options: dynamic
  start: reporting.app
In reporting.py there are a number of classes which are defined, which call different reports. My cron.yaml currently looks like this:
cron:
- description: update report 1
  url: /reports/report1
  schedule: every day 03:00
- description: update report 2
  url: /reports/report2
  schedule: every day 03:30
However logically this just calls the job on the frontend instance, through the app.yaml which currently looks like this:
application: appname
version: 1
runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /(robots\.txt)
  static_files: \1
  upload: (robots\.txt)
- url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico
- url: /sitemap\.xml
  static_files: sitemap.xml
  upload: sitemap\.xml
- url: /images
  static_dir: images
- url: /js
  static_dir: js
- url: /css
  static_dir: css
- url: /reports/.*
  script: reporting.app
  login: admin
What would I have to change to call these jobs on a backend instance on a daily basis?
解决方案
An easier way to do this is by migrating the app to modules. Explained here: https://developers.google.com/appengine/docs/python/modules/

After doing so, you can just add following line in the cron.yaml:
target: yourmodule
This allows the cron job to run on the instance defined in yourmodule.yaml
