Fields and annotations of the Service resource for the Gateway API
The Service resource represents the Kubernetes service. For the Gateway API, services are backends between which the incoming traffic is distributed within a Managed Service for Kubernetes cluster. Services representing Application Load Balancer backends are specified in the HTTPRoute resource.
Service is a standard Kubernetes resource. Below, you can find the descriptions of the resource fields and annotations the Application Load Balancer tools for Managed Service for Kubernetes interface with. For a full description of the resource configuration, see the Kubernetes documentation.
