Documentation

Overview

Package service defines the interface used by the launcher to communicate with the Kolide server. It currently only uses the gRPC transport, but could be extended to use others.

Types

type Endpoints

type Endpoints struct {
	RequestEnrollmentEndpoint endpoint.Endpoint
	RequestConfigEndpoint     endpoint.Endpoint
	PublishLogsEndpoint       endpoint.Endpoint
	RequestQueriesEndpoint    endpoint.Endpoint
	PublishResultsEndpoint    endpoint.Endpoint
	CheckHealthEndpoint       endpoint.Endpoint
}

Endpoints defines the endpoints implemented by the Kolide remote extension servers and clients.

func MakeServerEndpoints

func MakeServerEndpoints(svc KolideService) Endpoints

func (Endpoints) CheckHealth

func (e Endpoints) CheckHealth(ctx context.Context) (int32, error)

PublishLogs implements KolideService.PublishLogs

func (Endpoints) PublishResults

func (e Endpoints) PublishResults(ctx context.Context, nodeKey string, results []distributed.Result) (string, string, bool, error)

PublishResults implements KolideService.PublishResults

func (Endpoints) RequestConfig

func (e Endpoints) RequestConfig(ctx context.Context, nodeKey string) (string, bool, error)

RequestConfig implements KolideService.RequestConfig.

}

type KolideClient

type KolideClient = Endpoints

KolideClient is an alias for the Endpoints type. It's added to aid in maintaining backwards compatibility for imports.

type KolideService

type KolideService interface {
	// RequestEnrollment requests a node key for the host, authenticating
	// with the given enroll secret.
	RequestEnrollment(ctx context.Context, enrollSecret, hostIdentifier string, details EnrollmentDetails) (string, bool, error)
	// RequestConfig requests the osquery config for the host.
	RequestConfig(ctx context.Context, nodeKey string) (string, bool, error)
	// PublishLogs publishes logs from the osquery process. These may be
	// status logs or result logs from scheduled queries.
	PublishLogs(ctx context.Context, nodeKey string, logType logger.LogType, logs []string) (string, string, bool, error)
	// RequestQueries requests the distributed queries to execute.
	RequestQueries(ctx context.Context, nodeKey string) (*distributed.GetQueriesResult, bool, error)
	// PublishResults publishes the results of executed distributed queries.
	PublishResults(ctx context.Context, nodeKey string, results []distributed.Result) (string, string, bool, error)
	// CheckHealth returns the status of the remote API, with 1 indicating OK status.
