Setting up the webhooks

Our conversion is in place, so all that's left is to tell controller-runtime about our conversion.

Webhook setup for v1...

The v1 webhook handles conversion (as the hub) and provides validation/defaulting for the v1 CronJob format with a string-based schedule:

{{#literatego ./testdata/project/internal/webhook/v1/cronjob_webhook.go}}

Webhook setup for v2...

The v2 webhook provides validation and defaulting for the v2 CronJob format with the structured CronSchedule type. Note how the validation logic differs from v1 - it builds a cron expression from the individual schedule fields:

{{#literatego ./testdata/project/internal/webhook/v2/cronjob_webhook.go}}

...and main.go

Similarly, our existing main file is sufficient:

{{#literatego ./testdata/project/cmd/main.go}}

Everything's set up and ready to go! All that's left now is to test out our webhooks.
