是否可以在不发布的情况下更改 azure 函数的时间触发器（例如运行所有 x 分钟）？

Question

We are using timer triggered azure function with c#. We must change the last time more often than the NCRON-expression.

eg run all 5 minutes ("0 */5 * * * *") instead all 10 minutes ("0 */10 * * * *")

We deploy with run from package (ZIP-Deploy).

Is this possible to change the NCRON-Expression without publishing and change it with the Azure portal or in server-files with FTP or similar?

Answer 1

I have created the Azure Function App .NET 6 Timer Trigger of the CRON Expression ("0 */10 * * * *") with Zip Deploy. So, I cannot edit the CRON Expression as shown here:

AFAIK, To Edit the Timer Trigger Function App in Portal Menu, one of the workarounds is to write the CRON expression in local.settings.json file:

{
    "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "dotnet",
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "cron-expression":  "0 */10 * * * *"
  }
}

Timer Trigger Function Code :

 public void Run([TimerTrigger("%cron-expression%")] TimerInfo myTimer, ILogger log)

Publish using zip deploy to the Azure Portal Function App and create the app setting cron-expression to 0 */10 * * * * .

OR

In the Publish Window of VS, click on ellipsis icon > Select Manage Azure App Service Settings > Whatever the setting you want to publish to Azure Function App such as CRON Expression - click on Insert Value from local > Ok > Publish the Function Project.

After publishing for the 1st time, no need to publish for the change in CRON Expression, you can modify it using Azure Function App Configuration Menu .

After Modification through Azure portal :
