The charts maintains the internal networking and you wire the connection to the outside world. 
I use two ingress classes: Tailscale and nginx, and you can wire a service by adding to kustomization 
and [[https://fluxcd.io/][flux]] e.g. like the following.

** Nginx

To expose publicly via nginx:

#+BEGIN_SRC yaml
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: matrix-synapse-ingress
  namespace: messaging
  annotations:
    external-dns.alpha.kubernetes.io/target: ingress.${PUBLIC_DOMAIN}
spec:
  ingressClassName: nginx
  rules:
  - http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: matrix-synapse
            port:
              number: 8008
  tls:
  - hosts:
    - matrix
#+END_SRC

** Tailscale

To use the [[https://tailscale.com/kb/1236/kubernetes-operator/][Tailscale operator]]:

#+BEGIN_SRC yaml
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: hajimari-ingress
  namespace: home
spec:
  ingressClassName: tailscale
  rules:
  - http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: hajimari
            port:
              number: 3000
  tls:
  - hosts:
    - apps
