Do you know what is the annotation that we can use it on GKE to make a LoadBalancer service internal?. For example Azure (and AWS) supports the following annotation (shown in the YAML code snippet) to make a LoadBalancer service internal. I couldn’t find equivalent of it on GKE. For example naturally one may expect gcp-load-balancer-internal as the equivalent annotation on GKE; unfortunately it is not. Here is the Azure and AWS documentation for it, I am looking equivalent of it on GKE.
apiVersion: v1
kind: Service
metadata:
annotations:
service.beta.kubernetes.io/aws-load-balancer-internal: "true"
service.beta.kubernetes.io/azure-load-balancer-internal: "true"The equivalent can be found here.
apiVersion: v1
kind: Service
metadata:
name: ilb-service
annotations:
networking.gke.io/load-balancer-type: "Internal"
labels:
app: hello
spec:
type: LoadBalancer
selector:
app: hello
ports:
- port: 80
targetPort: 8080
protocol: TCPThere are 2 annotations:
For GKE versions 1.17 and later, use the annotation:
networking.gke.io/load-balancer-type: "Internal"For earlier versions, use the annotation:
cloud.google.com/load-balancer-type: "Internal"Plus, I’m sharing with you some GCP’s helpful official documentation in the following URLs Using an internal TCP/UDP load balancer and Setting up Internal HTTP(S) Load Balancing .
