Azure Schedule WebJob settings

Question

How can I run a webjob based off of settings.json instead of hardcoded value in TimerTrigger?

settings.json

{
  //Runs at 9:30 AM every day
  "schedule": "0 30 9 * * *"
}

Functions.cs

[Singleton]
public static void TimerTick([TimerTrigger("0 * * * * *")] TimerInfo myTimer)
{
    Console.WriteLine($"Hello at {DateTime.UtcNow.ToString()}");
}

It always uses the hard coded value: The next 5 occurrences of *the schedule (Cron: '0 * * * * ')

** will be:

How to do that is explained in the docs:

You can put the schedule expression in an app setting and set this property to the app setting name wrapped in % signs, as in this example: "%ScheduleAppSetting%".

So, in your case it would be something like this:

settings.json

{
  //Runs at 9:30 AM every day
  "schedule": "0 30 9 * * *"
}

Functions.cs

[Singleton]
public static void TimerTick([TimerTrigger("%schedule%")] TimerInfo myTimer)
{
    Console.WriteLine($"Hello at {DateTime.UtcNow.ToString()}");
}
