How to define and call a subresource?

[a01fe]

I'm writing a script to create and approve CertificateSigningRequests.

With the following, I'm able to create CSRs, but I'm not sure how to call the approval subresource to approve the CSR.
How do I do that? (https://kubernetes.io/docs/reference/kubernetes-api/authentication-resources/certificate-signing-request-v1/).

package dev.hnaderi.k8s.client

import apis.certificates._

trait CertificatesV1 {
  final val certificateSigningRequests = CertificateSigningRequestAPI
}

object CertificatesV1 extends APIGroupAPI("apis/certificates.k8s.io/v1") with CertificatesV1

package dev.hnaderi.k8s.client
package apis.certificates

import io.k8s.api.certificates.v1.CertificateSigningRequest
import io.k8s.api.certificates.v1.CertificateSigningRequestList

object CertificateSigningRequestAPI extends CertificatesV1.ClusterResourceAPI[CertificateSigningRequest, CertificateSigningRequestList]("certificatesigningrequests")

It needs a custom API request, as this API has its own subresource, You need something like this:

package dev.hnaderi.k8s.client
package apis.certificates

import io.k8s.api.certificates.v1.CertificateSigningRequest
import io.k8s.api.certificates.v1.CertificateSigningRequestList

object CertificateSigningRequestAPI
    extends CertificatesV1.ClusterResourceAPI[
      CertificateSigningRequest,
      CertificateSigningRequestList
    ]("certificatesigningrequests") {

  case class ApprovalRequest(
      name: String,
      body: CertificateSigningRequest,
      dryRun: Option[String] = None,
      fieldManager: Option[String] = None,
      fieldValidation: Option[String] = None
  ) extends ReplaceRequest(
        s"${urlFor(name)}/approval",
        body,
        dryRun = dryRun,
        fieldManager = fieldManager,
        fieldValidation = fieldValidation
      )

  def approve(
      name: String,
      csr: CertificateSigningRequest,
      dryRun: Option[String] = None,
      fieldManager: Option[String] = None,
      fieldValidation: Option[String] = None
  ): ApprovalRequest = ApprovalRequest(
    name,
    csr,
    dryRun = dryRun,
    fieldManager = fieldManager,
    fieldValidation = fieldValidation
  )
}

And then you can use it like:

  CertificatesV1.certificateSigningRequests.approve("csr-name", csrWithApprovedConditionInStatus)

I'll add this API to the next version as well, let me know if you had any suggestions on it, or any other useful missing APIs in the base client.

Awesome, ty so much! Having all the generated resource definitions in io.k8s.api really helps!
