type SessionService 

type SessionService interface {

	// Run should run the Session service. Run will be launched in its own goroutine and it's expected that it blocks until the context is finished.
	Run(ctx context.Context, scout *scout.Reporter, session Session) error
}

A SessionService represents a service that should be started together with each daemon session. Can be used when passing in custom commands to start up any resources needed for the commands.

type TrafficManager 

type TrafficManager struct {
	// contains filtered or unexported fields
}

func (*TrafficManager) AddIntercept 

func (tm *TrafficManager) AddIntercept(c context.Context, ir *rpc.CreateInterceptRequest) (result *rpc.InterceptResult, err error)

AddIntercept adds one intercept

func (*TrafficManager) AddInterceptor added in v2.6.0 

func (tm *TrafficManager) AddInterceptor(s string, i int) error

AddInterceptor associates the given interceptId with a pid of a running process. This ensures that the running process will be signalled when the intercept is removed

func (*TrafficManager) AddLocalOnlyIntercept 

func (tm *TrafficManager) AddLocalOnlyIntercept(c context.Context, spec *manager.InterceptSpec) (*rpc.InterceptResult, error)

AddLocalOnlyIntercept adds a local-only intercept

func (*TrafficManager) CanIntercept 

func (tm *TrafficManager) CanIntercept(c context.Context, ir *rpc.CreateInterceptRequest) (*serviceProps, *rpc.InterceptResult)

CanIntercept checks if it is possible to create an intercept for the given request. The intercept can proceed only if the returned rpc.InterceptResult is nil. The returned runtime.Object is either nil, indicating a local intercept, or the workload for the intercept.

func (*TrafficManager) ClearIntercepts added in v2.6.0 

func (tm *TrafficManager) ClearIntercepts(c context.Context) error

ClearIntercepts removes all intercepts

func (TrafficManager) EnsureAgent 

func (ki TrafficManager) EnsureAgent(
	c context.Context,
	obj k8sapi.Workload,
	svcProps *serviceProps,
	agentImageName string,
	telepresenceAPIPort uint16,
) (string, string, error)

EnsureAgent does a lot of things but at a high level it ensures that the traffic agent is installed alongside the proper workload. In doing that, it also ensures that the workload is referenced by a service. Lastly, it returns the service UID associated with the workload since this is where that correlation is made. Deprecated: not used with traffic-manager versions >= 2.6.0

func (TrafficManager) EnsureManager 

func (ki TrafficManager) EnsureManager(c context.Context) error

func (*TrafficManager) GatherLogs added in v2.5.5 

func (tm *TrafficManager) GatherLogs(ctx context.Context, request *connector.LogsRequest) (*connector.LogsResponse, error)

GatherLogs acquires the logs for the traffic-manager and/or traffic-agents specified by the connector.LogsRequest and returns them to the caller

func (*TrafficManager) GetInterceptSpec 

func (tm *TrafficManager) GetInterceptSpec(name string) *manager.InterceptSpec

GetInterceptSpec returns the InterceptSpec for the given name, or nil if no such spec exists

func (*TrafficManager) IngressInfos 

func (tm *TrafficManager) IngressInfos(c context.Context) ([]*manager.IngressInfo, error)

func (*TrafficManager) InterceptInfo 

func (tm *TrafficManager) InterceptInfo(ctx context.Context, callerID, path string, _ uint16, headers http.Header) (*restapi.InterceptInfo, error)

func (*TrafficManager) InterceptsForWorkload added in v2.6.1 

func (tm *TrafficManager) InterceptsForWorkload(workloadName, namespace string) []*manager.InterceptSpec

InterceptsForWorkload returns the client's current intercepts on the given namespace and workload combination

func (*TrafficManager) ManagerClient 

func (tm *TrafficManager) ManagerClient() manager.ManagerClient

func (*TrafficManager) RemainWithToken 

func (tm *TrafficManager) RemainWithToken(ctx context.Context) error

func (*TrafficManager) RemoveIntercept 

func (tm *TrafficManager) RemoveIntercept(c context.Context, name string) error

RemoveIntercept removes one intercept by name

func (*TrafficManager) RemoveInterceptor added in v2.6.0 

func (tm *TrafficManager) RemoveInterceptor(s string) error

func (*TrafficManager) RemoveLocalOnlyIntercept 

func (tm *TrafficManager) RemoveLocalOnlyIntercept(c context.Context, name, namespace string) error

func (TrafficManager) RemoveManagerAndAgents 

func (ki TrafficManager) RemoveManagerAndAgents(c context.Context, agentsOnly bool, agents []*manager.AgentInfo) error

RemoveManagerAndAgents will remove the agent from all deployments listed in the given agents slice. Unless agentsOnly is true, it will also remove the traffic-manager service and deployment. Deprecated: not used with traffic-manager versions >= 2.6.0

func (*TrafficManager) Run 

func (tm *TrafficManager) Run(c context.Context) error

Run (1) starts up with ensuring that the manager is installed and running, but then for most of its life

  • (2) calls manager.ArriveAsClient and then periodically calls manager.Remain
  • run the intercepts (manager.WatchIntercepts) and then
  • (3) listen on the appropriate local ports and forward them to the intercepted Services, and
  • (4) mount the appropriate remote volumes.

func (*TrafficManager) Status 

func (tm *TrafficManager) Status(c context.Context) *rpc.ConnectInfo

func (*TrafficManager) Uninstall 

func (tm *TrafficManager) Uninstall(ctx context.Context, ur *rpc.UninstallRequest) (*rpc.UninstallResult, error)

Uninstall parts or all of Telepresence from the cluster if the client has sufficient credentials to do so.

Uninstalling everything requires that the client owns the helm chart installation and has permissions to run a `helm uninstall traffic-manager`.

Uninstalling all or specific agents require that the client can get and update the agents ConfigMap.

func (*TrafficManager) UpdateStatus 

func (tm *TrafficManager) UpdateStatus(c context.Context, cr *rpc.ConnectRequest) *rpc.ConnectInfo

func (*TrafficManager) WatchWorkloads 

func (tm *TrafficManager) WatchWorkloads(c context.Context, wr *rpc.WatchWorkloadsRequest, stream WatchWorkloadsStream) error

func (*TrafficManager) WorkloadInfoSnapshot

	includeLocalIntercepts bool,
) (*rpc.WorkloadInfoSnapshot, error)

type WatchWorkloadsStream 

type WatchWorkloadsStream interface {
	Send(*rpc.WorkloadInfoSnapshot) error
}
