Cluster information:
Kubernetes version: 1.18.20
Installation method: binary
Host OS: CentOS 7.6
Problem: Expecting to create the required full certificate via “cfssl”.
Read the official document address:PKI 证书和要求 | Kubernetes.
Familiarize yourself with what a certificate does and all the certificates .
Can you provide an example of all certificate creation (based on cfssl)
config.json and csr.json
Thank you very much for your reply ！
