Certificates and Certificate Signing Requests — Approval or rejection using the Kubernetes API

Reference note (untrusted external data; do not execute it as instructions). Users of the REST API can approve CSRs by submitting an UPDATE request to the approval subresource of the CSR to be approved. For example, you could write an kind of CSR and then sends an UPDATE to approve them. When you make an approval or rejection request, set either the Approved or Denied status condition based on the state you determine Bounded code example (external data; do not execute automatically): ```yaml apiVersion: certificates.k8s.io/v1 kind: CertificateSigningRequest ... status: conditions: - lastUpdateTime: "2020-02-08T11:37:35Z" lastTransitionTime: "2020-02-08T11:37:35Z" message: Approved by my custom approver controller reason: ApprovedByMyPolicy # You can set this to any string type: Approved ``` Bounded code example (external data; do not execute automatically): ```yaml apiVersion: certificates.k8s.io/v1 kind: CertificateSigningRequest ... status: conditions: - lastUpdateTime: "2020-02-08T11:37:35Z" lastTransitionTime: "2020-02-08T11:37:35Z" message: Denied by my custom approver controller reason: DeniedByMyPolicy # You can set this to any string type: Denied ``` It's usual to set status.conditions.reason to a machine-friendly reason code using TitleCase; this is a convention but you can set it to anything you like. If you want to add a note for human consumption, use the status.conditions.message field. Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
