Access cockrochdb out of kubernetes cluster

Hello. I created a three nodes cluster in a Kubernetes using official helm chart. All works fine expect I can’t access the cluster out of the cluster.

/cockroach sql --certs-dir=$LPATH/cockroach-cert --host=external_ip_here

ERROR: x509: certificate is valid for 127.0.0.1, not external_ip_here

kubectl describe csr tcc.node.cockroachdb-0
Name: tcc.node.cockroachdb-0

Is there a way to add external ip address or DNS name for the CSR ?

addresses = flag.String(“addresses”, “”, “comma-separated list of DNS names and IP addresses for node certificate”)
