<p>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 <strong>gcp-load-balancer-internal</strong> 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.</p>
