Hi, 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 ?

@Maciej Bąk Thank you for reaching out to Microsoft Q&A. I assume you are using Azure Spring Apps and looking to get instance name, you can follow the below docs: REST API: [Services - List][1]: Get list of service instances under resource group. [Apps - List][2]: Get list of app instances under service name including app instance name. PowerShell: Get-AzSpringCloud : Get list of service instances under resource group. Get-AzSpringCloudApp : Get list of app instances under service name including app instance name. Update: For Java SDK, you can use azure-resourcemanager library and Manage Spring Cloud sample listed here would help with few other scenarios. To list all spring apps under a spring service, use the below code snippet: List<SpringApp> springApps = springService.apps().list().stream().toList(); I hope this helps with your question, and feel free to add a comment for questions. Please 'Accept as answer' and ‘Upvote’ if it helped so that it can help others in the community.

@Maciej Bąk No issues at all. Can you please elaborate on what do you mean by the current instance?
The app can have multiple deployments and if you are looking to get app instances name of the active deployment, then use the below code snippet which will retrieve the active deployment and then all the instances. DeploymentInstance.name() is the app instance name.

SpringApp app = springService.apps().getByName(appName); List<DeploymentInstance> appInstances = app.getActiveDeployment().instances()

For app container, we can read from environment variable HOSTNAME to get the app instance name using System.getenv("HOSTNAME"). Please let me know or feel free to tag me if you have any further questions (no need to un-accept the answer :)).
