func ControllerReadinessCheck

func ControllerReadinessCheck(port int32, authflag bool) []string

This function check for the readiness of the controller in the following cases 1) Auth and TLS Enabled- in this case, we check if the controller is properly enabled with authentication or not and we do a get on controller and with dummy credentials(testtls:testtls) and the controller returns 401 error in this case if it's correctly configured 2) Auth Enabled and TLS Disabled- in this case, we check if the controller is properly enabled with authentication or not and we do a get on controller and with dummy credentials(testtls:testtls) and the controller returns 401 error in this case if it's correctly configured 3) Auth Disabled and TLS Enabled- in this case, we check if the controller can create scopes or not by checking if _system scope is present or not 4) Auth and TLS Disabled- in this case, we check if the controller can create scopes or not by checking if _system scope is present or not

Types

type OrderedMap

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

OrderedMap is a map that has insertion order when iterating. The iteration of map in GO is in random order by default.
