Documentation

Overview

Package authz converts Istio RBAC (role-based-access-control) policies (ServiceRole and ServiceRoleBinding) to corresponding filter config that is used by the envoy RBAC filter to enforce access control to the service co-located with envoy. Currently the config is only generated for sidecar node on inbound HTTP listener. The generation is controlled by RbacConfig (a singleton custom resource with cluster scope). User could disable this plugin by either deleting the RbacConfig or set the RbacConfig.mode to OFF. Note: no RbacConfig is created in the deployment of Istio which means this plugin doesn't generate any RBAC config by default.

Types

type Plugin

type Plugin struct{}

Plugin implements Istio RBAC authz

func (Plugin) OnInboundCluster

func (Plugin) OnInboundCluster(env model.Environment, node model.Proxy, service *model.Service,
	servicePort *model.Port, cluster *xdsapi.Cluster)

OnInboundCluster implements the Plugin interface method.

func (Plugin) OnInboundListener

	servicePort *model.Port, cluster *xdsapi.Cluster)

OnOutboundCluster implements the Plugin interface method.

func (Plugin) OnOutboundListener

func (Plugin) OnOutboundListener(in *plugin.InputParams, mutable *plugin.MutableObjects) error

OnOutboundListener is called whenever a new outbound listener is added to the LDS output for a given service Can be used to add additional filters on the outbound path

func (Plugin) OnOutboundRouteConfiguration

func (Plugin) OnOutboundRouteConfiguration(in *plugin.InputParams, route *xdsapi.RouteConfiguration)

OnOutboundRouteConfiguration implements the Plugin interface method.
