Overview

Package adapter_template_kubernetes is a generated protocol buffer package.

The `kubernetes` template holds data that controls the production of Kubernetes-specific attributes.

Example config:

```yaml apiVersion: "config.istio.io/v1alpha2" kind: kubernetes metadata:

name: attributes
namespace: istio-system

spec:

# Pass the required attribute data to the adapter
source_uid: source.uid | ""
source_ip: source.ip | ip("0.0.0.0") # default to unspecified ip addr
destination_uid: destination.uid | ""
destination_ip: destination.ip | ip("0.0.0.0") # default to unspecified ip addr
attribute_bindings:
  # Fill the new attributes from the adapter produced output.
  # $out refers to an instance of OutputTemplate message
  source.ip: $out.source_pod_ip
  source.labels: $out.source_labels
  source.namespace: $out.source_namespace
  source.service: $out.source_service
  source.serviceAccount: $out.source_service_account_name
  destination.ip: $out.destination_pod_ip
  destination.labels: $out.destination_labels
  destination.namespace: $out.destination_mamespace
  destination.service: $out.destination_service
  destination.serviceAccount: $out.destination_service_account_name

```

The `kubernetes` template represents data used to generate kubernetes-derived attributes.

The values provided controls the manner in which the kubernetesenv adapter discovers and generates values related to pod information. Next ID: 8

It is generated from these files:

	// 'kubernetes' instance.
	Instance *InstanceMsg `protobuf:"bytes,1,opt,name=instance" json:"instance,omitempty"`
	// Adapter specific handler configuration.
	//
	// Note: Backends can also implement [InfrastructureBackend][https://istio.io/docs/reference/config/mixer/istio.mixer.adapter.model.v1beta1.html#InfrastructureBackend]
	// service and therefore opt to receive handler configuration during session creation through [InfrastructureBackend.CreateSession][TODO: Link to this fragment]
	// call. In that case, adapter_config will have type_url as 'google.protobuf.Any.type_url' and would contain string
	// value of session_id (returned from InfrastructureBackend.CreateSession).

}

func NewHandleKubernetesServiceClient

func NewHandleKubernetesServiceClient(cc *grpc.ClientConn) HandleKubernetesServiceClient

type HandleKubernetesServiceServer

}

Handler must be implemented by adapter code if it wants to process data associated with the 'kubernetes' template.

Mixer uses this interface to call into the adapter at request time in order to dispatch created instances to the adapter. Adapters take the incoming instances and do what they need to achieve their primary function.

type HandlerBuilder

type HandlerBuilder interface {
	adapter.HandlerBuilder
}

HandlerBuilder must be implemented by adapters if they want to process data associated with the 'kubernetes' template.

Mixer uses this interface to call into the adapter at configuration time to configure it with adapter-specific configuration as well as all template-specific type information.

type Instance

type Instance struct {
	// Name of the instance as specified in configuration.
	Name string

	// Source pod's uid. Must be of the form: "kubernetes://pod.namespace"

	// returned by the attribute producing adapters using $out.<fieldName> notation. For example:
	// source.ip : $out.source_pod_ip
	// In the above example, source.ip attribute will be added to the existing attribute list and its value will be set to
	// the value of source_pod_ip field of the output returned by the adapter.
