-1.  Download, unpack, and initialize the patched version of easyrsa3.
-

-        tar xzf easy-rsa.tar.gz
-        cd easy-rsa-master/easyrsa3
-        ./easyrsa init-pki
-1.  Generate a new certificate authority (CA). `--batch` sets automatic mode;
-    `--req-cn` specifies the Common Name (CN) for the CA's new root certificate.
-
-        ./easyrsa --batch "--req-cn=${MASTER_IP}@`date +%s`" build-ca nopass
-1.  Generate server certificate and key.
-    The argument `--subject-alt-name` sets the possible IPs and DNS names the API server will
-    be accessed with. The `MASTER_CLUSTER_IP` is usually the first IP from the service CIDR
-    that is specified as the `--service-cluster-ip-range` argument for both the API server and
-    the controller manager component. The argument `--days` is used to set the number of days
-    after which the certificate expires.
-    The sample below also assumes that you are using `cluster.local` as the default
-    DNS domain name.
