Chapter 11 is outdated and should be replaced.

Are we supposed to actually be able to run the manifests and execute the steps in the class notes or just wait for the lab itself?
There are problems with the simple ingress resource configuration 1) typo 2) old conventions 3) relying on a single ingress controller being installed.:

apiVersion: networking.k8s.io/v1 
kind: Ingress 
metadata:
  name: ghost-ingress
spec:
**# missing something like: ingressClassName: nginx**
  rules:
  - host: ghost.192.168.99.100.nip.io
    http:
      paths:
      - path: /
        pathType: ImplementationSpecific  # <-- should be Prefix
        backend:
         ** service  # <--- missing colon**
            name: ghost
            port:
              number: 2368
