Expose your service via Ingress

To expose an HTTP service over TLS, you add a Kubernetes Ingress resource, e.g.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    external-dns.alpha.kubernetes.io/hostname: {{ service-host }}
    external-dns.alpha.kubernetes.io/target: {{ ingress-host }}
  name: reference-service
  namespace: golang-dev
spec:
  ingressClassName: platform-ingress
  rules:
  - host: {{ service-host }}
    http:
      paths:
      - backend:
          service:
            name: reference-service
            port:
              number: 80
        path: /
        pathType: ImplementationSpecific

The important parts are:

• external-dns.alpha.kubernetes.io/target must match one of the ingress domains defined in environment config yaml file in Environments Repo
• external-dns.alpha.kubernetes.io/hostname has to be a subdomain of the target
• ingressClassName must be platform-ingress

Your service will now be available over the Internet over TLS.
