kubectl apply -f ingress.yaml

error: resource mapping not found for name: "your-ingress" namespace: "your-namespace" from "ingress.yaml": no matches for kind "Ingress" in version "networking.k8s.io/v1beta1" ensure CRDs are installed first

Solution: change networking.k8s.io/v1beta1 for networking.k8s.io/v1 or your K8s version: kubectl api-resources | grep networking.k8s.io

error: error validating "ingress.yaml": error validating data: [ValidationError(Ingress.spec.rules[0].http.paths[0].backend): unknown field "serviceName" in io.k8s.api.networking.v1.IngressBackend, ValidationError(Ingress.spec.rules[0].http.paths[0].backend): unknown field "servicePort" in io.k8s.api.networking.v1.IngressBackend]; if you choose to ignore these errors, turn validation off with --validate=false
