As I was following this documantation I got this error:
error: resource mapping not found for name: “testuser-authentication” namespace: “” from “STDIN”: no matches for kind “CertificateSigningRequest” in version “certificates.k8s.io/v1beta1” ensure CRDs are installed first
When I tried this script:
cat <<EOF | kubectl apply -f - apiVersion: certificates.k8s.io/v1beta1 kind: CertificateSigningRequest metadata: name: testuser-authentication spec: groups: - system:authenticated request: $(cat ~/certs/testuser.csr | base64 | tr -d '\n') usages: - digital signature - key encipherment - server auth - client auth EOF
that I took from the docmunation from “Managing Certificate Signing Requests with the Kubernetes API” character.
Please help to solve the problem
