Define how to express uri and email forms (Renamed)

[mattfarina]

Is there a way to specify validation for things just as email and URL/URI?

@mattfarina Good question. This is all done through the openAPI v3 validation supported by CRDs. Do you know what the CRD validation supports? I may need to add an extra hook.

I am not totally clear from this document about what validation is supported by openAPI v3: https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.0.md. It mentions uuid and email as formats but says they are undefined by the spec.

If nothing else, you may be able to use "Pattern".

@pwittrock Two things...

1. How do I specify a custom data type such as email? What's the right annotation? https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.0.md#data-types
2. What's the right annotation to set the pattern?

@mattfarina

1. This may not be supported today, but should be possible to add with relatively little work if the CRD validation supports this use case.

2. Sorry about this. I'll update the godoc documentation to include Pattern and the other supported types. For now this should work. Remember to run kubebuilder generate afterward.

// +kubebuilder:validation:Pattern=^[a-z]+$

@mattfarina Filed #67 to support annotating fields with the format generated for openapi.

@pwittrock Thanks. You can consider my question answered. I'll leave this open in case you want to keep it open until you've updated the godocs. Or, you can close it if not.
