How do you schedule a Java Task (cron) on app engine flexible?

Question

How do you create a Java long running scheduled task (like every hour) on app engine flexible environment?

The only docs I can find are for standard environment: https://cloud.google.com/appengine/docs/standard/java/config/cron

Is there anything in the platform?

Answer 1

Yes, it does. Documentation is here for Flexible/Java.

To upload your cron jobs, you must specify the cron.yaml as a parameter to the following gcloud command:

gcloud app deploy cron.yaml

To delete all cron jobs, change the cron.yaml file to just contain:

cron:

The cron.yaml file lives in the WEB-INF directory of your application (alongside app.yaml). The following is an example cron.yaml file:

cron:
- description: daily summary job
  url: /tasks/summary
  schedule: every 24 hours
