You probably need to migrate to apiVersion networking.k8s.io/v1 for your Ingress rules (given that after Kubernetes 1.22, the old apiVersion extensions/v1beta1 and networking.k8s.io/v1beta1 will simply disappear). If you are managing your Ingress rules through Go, here is a snippet to generate a valid Ingress rule if that can help you (I struggled a little to find the correct template so I am sharing this post).
Please let me know it this snippet was useful or if you see some improvements that we can make to it.
Have a great day!
import (
v1Networking "k8s.io/api/networking/v1"
v1 "k8s.io/apimachinery/pkg/apis/meta/v1"
)
func MapIngress(ingressName string, hostName string) *v1Networking.Ingress {
annotations := map[string]string{}
annotations["kubernetes.io/ingress.provider"] = "nginx"
annotations["kubernetes.io/ingress.class"] = "yourIngressClass"
annotations["kubernetes.io/tls-acme"] = "true"
// add other annotations you need
meta := v1.ObjectMeta{
Name: ingressName,
Annotations: annotations,
}
pathTypeImplementationSpecific := v1Networking.PathTypeImplementationSpecific
return &v1Networking.Ingress{
ObjectMeta: meta,
Spec: v1Networking.IngressSpec{
TLS: []v1Networking.IngressTLS{
v1Networking.IngressTLS{
Hosts: []string{hostName},
SecretName: "yourSecretName",
},
Rules: []v1Networking.IngressRule{
v1Networking.IngressRule{
Host: hostName,
IngressRuleValue: v1Networking.IngressRuleValue{
HTTP: &v1Networking.HTTPIngressRuleValue{
Paths: []v1Networking.HTTPIngressPath{
v1Networking.HTTPIngressPath{
Path: "/",
PathType: &pathTypeImplementationSpecific,
Backend: v1Networking.IngressBackend{
Service: &v1Networking.IngressServiceBackend{
Name: "yourServiceName",
Port: v1Networking.ServiceBackendPort{
Number: 80,
},
},
},
},
},
},
},
},
},
},
}
}
