Question
How to manage certificate signing requests with the Kubernetes API

Asked by Maro Hamamjyan
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.
