No Deployments Created when Creating a Spring Boot App

Question

I have deployed a spring app called shape-shop-app :

It says the application failed to start and I should check the logs.

This is what it looks like in Azure :

This is where I am confused.

Where are the logs?

If I go to the console for shape-shop-app then it is empty.

If I go to the "Azure Spring Apps" Logs tab then I am bombarded with thousands of queries I can choose from. I really just want to find out what error caused my spring app to go down but I am lost among all these specific log queries. The most generic queries yield no results.

How can I diagnose why my spring app failed to start in azure?

Answer 1

Application failed to start.

Generally, this error occurs when the application is not deployed properly (or) If any file/configuration is missing. Re-deploy your application to fix the issue.

If I go to the console for shape-shop-app then it is empty.

Select your App instance from the drop down in the Console and click on Connect.

To check the logs use the query:

az spring app logs --resource-group <Resource_group_name> --service <Service_instance_name> --name <App_name> --follow

Refer MSDOC for Monitoring Azure Spring Apps with logs, metrics, and tracing.

• You can also enable Remote debugging. This helps to attach a debugger to the application and figure out the issue.
