Exercise — Generating Ingress With Kyverno

When a Service gets created...

(for instance, Service blue in Namespace rainbow)

...Automatically generate an Ingress.

(for instance, with host name blue.rainbow.MYDOMAIN.COM)

---

Goals

• Step 1: expose all services with a hard-coded domain name

• Step 2: only expose services that have a port named http

• Step 3: configure the domain name with a per-namespace ConfigMap

  (e.g. kubectl create configmap ingress-domain-name --from-literal=domain=1.2.3.4.nip.io)
