2.11. Debugging applications in odo
With odo
, you can attach a debugger to remotely debug your application. This feature is only supported for NodeJS and Java components.
Components created with odo
run in the debug mode by default. A debugger agent runs on the component, on a specific port. To start debugging your application, you must start port forwarding and attach the local debugger bundled in your Integrated development environment (IDE).
2.11.1. Debugging an application
You can debug your application on in odo
with the odo debug
command.
Procedure
After an application is deployed, start the port forwarding for your component to debug the application:
$ odo debug port-forward
- Attach the debugger bundled in your IDE to the component. Instructions vary depending on your IDE.
2.11.2. Configuring debugging parameters
You can specify a remote port with odo config
command and a local port with the odo debug
command.
Procedure
To set a remote port on which the debugging agent should run, run:
$ odo config set DebugPort 9292
注意You must redeploy your component for this value to be reflected on the component.
To set a local port to port forward, run:
$ odo debug port-forward --local-port 9292
注意The local port value does not persist. You must provide it every time you need to change the port.
