ingress-nginx: cannot install 1.0.4 on K8s v1.19

NGINX Ingress controller version: 1.0.4

Kubernetes version: v1.19.13-gke.1200

Environment:

• Cloud provider or hardware configuration: GKE

• OS (e.g. from /etc/os-release): Container-Optimized OS from Google

• Kernel (e.g. uname -a): 5.4.129

• Basic cluster related info:

  • Server Version: version.Info{Major:"1", Minor:"19+", GitVersion:"v1.19.13-gke.1200", GitCommit:"ee714a7b695ca42b9bd0c8fe2c0159024cdcba5e", GitTreeState:"clean", BuildDate:"2021-08-03T09:21:57Z", GoVersion:"go1.15.13b5", Compiler:"gc", Platform:"linux/amd64"}

• How was the ingress-nginx-controller installed:

  • Using the yaml file mentioned on install guide: https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.0.4/deploy/static/provider/cloud/deploy.yaml

What happened: When applying the yaml file, it returned unknown field "ipFamilies" in io.k8s.api.core.v1.ServiceSpec:

error: error validating "https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.0.4/deploy/static/provider/cloud/deploy.yaml": error validating data: [ValidationError(Service.spec): unknown field "ipFamilies" in io.k8s.api.core.v1.ServiceSpec, ValidationError(Service.spec): unknown field "ipFamilyPolicy" in io.k8s.api.core.v1.ServiceSpec]; if you choose to ignore these errors, turn validation off with --validate=false

What you expected to happen: Installed as expected, because controller 1.0.4 should support k8s 1.19

How to reproduce it: Install 1.0.4 controller on K8s 1.19

Anything else we need to know: service.spec.ipFamilyPolicy required Kubernetes 1.20. I had try to install 1.0.3(without service.spec.ipFamilyPolicy) controller and it’s work
