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: {}
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).
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.
