ON-PREM : Helm : How to provide ssh access to git via values.yaml and the hostname?

Currently, I am only able to access git ssh via loadbalancer ip/port.
ex: ssh 10.30.12.5 -p 12222

Available via
service/jb-space-vcs-ext                LoadBalancer   10.108.218.156   10.30.12.5    12222:31458/TCP       18h

Using the hostname does not work.  ex: ssh git.space.poc.k8s.mydomain.com -p 12222

The vcs portion of my values.yaml.  I am not sure if I need to do something with vcs.externalService.*

vcs:
  storage:
    eventbus:
      hostname: "redis-master"
      port: "6379"
      password: "password"
