Auto assigned nodeId for azure spring app or how to get app instance name

In azure spring boot app while having multiple instances I need to get somehow its app instance name, or would be perfect to configure nodeId generation ( int/long type , but if now I can live with name ). Anyone knows how to access this data from code ?

To get app instances name list from application code, you may try to use the following REST API:

1. To list all the instances names in an app, we can use

GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.AppPlatform/Spring/{serviceName}/apps/{appName}/deployments?api-version=2022-12-01

You should be able to find all the instances name in the response json file.

{
  "value": [
    {
      "properties": {
        ...,
        "instances": [
          {
            "name": "<app name>-<deployment name>-x-xxxxxxxx-xxxx",
            "status": "Running",
            "discoveryStatus": "UP",
            "startTime": "2023-xx-xxTxx:xx:xxZ"
          },
          ...
        ],

2. To list all the instances names in the Azure Spring Apps service:

GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.AppPlatform/Spring/{serviceName}/deployments?api-version=2022-12-01

You can find the instance list in the 'properies' -> 'instances' of the request response.

3. You can also use Azure Resource Manager App Platform client library for Java SDK to access the information in your code.
