Debugging

You can use Cloud Code to debug your application:

1. Click Cloud Code in the status bar, and select Debug on Kubernetes:

Figure 3.19 – Selecting the Debug on Kubernetes option

Cloud Code deploys your app in debug mode to your GKE cluster, remembering the choices you made before.

2. In the HelloController.java file, set a breakpoint at line 16 by clicking the blank space to the left of the line number.

   Line 16 is the line that has the return statement you updated previously. A red indicator shows that the breakpoint is set.

3. Go back to the Cloud Code section, and in the Port Forward URLs folder, click on service | java-scdongcp-external.

Important note

The debugger stops the process at the breakpoint so you can investigate the variables and state of the application:

4. Show the DEBUG view.
