Spring Cloud Function on Azure run locally

I am busy with a demo application to show the power of Cloud Functions in general and specific Spring Cloud Function.

I was already able to deploy the Demo application on IBM Cloud, next step is to run in it on Azure.

Prepare the application

I found a very good article by Microsoft which explain how to prepare your Spring Cloud Function application before it can be deployed to Azure.

First run it locally

After the preparations I tried to run the application locally. Microsoft did a great job to make this possible. Helps speed up the development of the application before the actual deployment.

But when I tried to run the application locally it failed with a stack trace. After some searching on the internet I found the solution.

I need to the Main Class to the local.settings.json file, which point to the start class of the application. After I added this line I was able to run my demo application locally.

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "",
    "FUNCTIONS_WORKER_RUNTIME": "java",
    "AzureWebJobsDashboard": "",
    "MAIN_CLASS":"nl.elstarit.nl.demo.functions.demo.DemoFunction"
  }
}

The last step, the actual deployment to Azure was very easy.
