Error: [service-account-issuer is a required flag, --service-account-signing-key-file and --service-account-issuer are required flags]

解决办法

生成sa证书和pub

cat< /root/k8s/certs/sa-csr.json 
{
    "CN":"sa",
    "key":{
        "algo":"rsa",
        "size":2048
    },
    "names":[
        {
            "C":"CN",
            "L":"BeiJing",
            "ST":"BeiJing",
            "O":"k8s",
            "OU":"System"
        }
    ]
}
