Debugging

Debug locally

To debug in Kind and hit breakpoints on your laptop, follow these steps:

1. Ensure you have the operator deployed locally.
2. Set a breakpoint in ./controllers/prescaledcronjob_controller.go and hit F5
3. Create a new prescaledcronjob object: make recreate-sample-psccron
4. all being well... your breakpoint will get hit.

Checking the logs

The Operator records debug information with the logs for the controller manager. To view them:

• run kubectl get pods -A
• copy the name of your controller manager, for example: pod/psc-controller-manager-6544fc674f-nl5d2
• run kubectl logs <pod name> -n psc-system manager (so in our example: kubectl logs pod/psc-controller-manager-6544fc674f-nl5d2 -n psc-system manager)

Checking object events

The Operator records events on the PreScaledCronJob objects as they occur. To view them:

• run kubectl describe prescaledcronjobs <your prescaledcronjob name here> -n psc-system
• you will be shown all events that have taken place related to the prescaledcronjob object you created
