Ingress v1beta has been deprecated, and there is a bit of syntax change in the service definition, i.e. instead of serviceName and servicePort:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  creationTimestamp: null
  name: ingressName
spec:
  ingressClassName: default
  rules:
  - host: foo.com
    http:
      paths:
      - backend:
          service:
            name: svcName
            port:
              number: 80
        path: /bar
        pathType: Exact
status:
  loadBalancer: {}

I can not find where is the namespace has been assigned in the LimitRange - mem-limit-range.

Need to add:-

1- Save the " LimitRange - mem-limit-range" as a mem-limit-range.yaml:
2- Run the below command:-
kubectl apply -f mem-limit-range.yaml --namespace=tenant-b-100mi

Same issue in the pod definition, we need to add namespace=tenant-b-100mi on the metadata section.

Is this study guide relevant to the latest curriculum 1.14.1?

Is this lab possible on the exam? I didn't saw it in any course I did. (I know how to list members, create backup, check backups and restore backups for etcd).
