Functions

func ConstructMuxVar

func ConstructMuxVar(name string, pattern string) string

ConstructMuxVar constructs the mux var that is used in the gorilla/mux styled path, example: {id}, {id:[0-9]+}.

func GetMuxValueFromRequest

func GetMuxValueFromRequest(r *http.Request, gorillaMuxName string) (string, bool)

GetMuxValueFromRequest extracts the mux value from the request using a gorilla mux name

func LimitReachedHandler

func LimitReachedHandler(auditLogger audit.AuditLogger) func(http.ResponseWriter, *http.Request)

LimitReachedHandler logs the throttled request in the credentials audit log

func ValueFromRequest

func ValueFromRequest(r *http.Request, field string) (string, bool)

ValueFromRequest returns the value of a field in the http request. The boolean value is set to true if the field exists in the query.

func WriteJSONToResponse

func WriteJSONToResponse(w http.ResponseWriter, httpStatusCode int, responseJSON []byte, requestType string)

WriteJSONToResponse writes the header, JSON response to a ResponseWriter, and log the error if necessary.

Types

type DockerStateResolver

type DockerStateResolver interface {
	State() dockerstate.TaskEngineState
}

DockerStateResolver is a sub-interface for the engine.TaskEngine interface to make it easy to test code in this package

type ErrorMessage

type ErrorMessage struct {
	Code          string `json:"code"`
	Message       string `json:"message"`
	HTTPErrorCode int
}

ErrorMessage is used to store the human-readable error Code and a descriptive Message that describes the error. This struct is marshalled and returned in the HTTP response.
