Update Scheduler

There are two ways to update the configuration of the scheduler:

1. Add the config in the DevOps environment file, and restart the service. This will trigger the scheduler based on the updated environment configuration and restart the expense-cronjob service.

expense-cronjob:
  cron:
    schedule: "*/1 * * * *"
    suspend: "false"

1. Use the commands given below: Change schedule - kubectl patch cronjobs expense-cronjob -p '{"spec" : {"schedule": "*/10 * * * *" }}'

   Pause cron job - kubectl patch cronjobs expense-cronjob -p '{"spec" : {"suspend" : true }}' Resume cron job - kubectl patch cronjobs expense-cronjob -p '{"spec" : {"suspend" : false}}' Create a new cronjob scheduler - kubectl create job --from=cronjob/expense-cronjob expense-cronjob
