Functions ¶

func CloneDetectOptions ¶

func CloneDetectOptions(oldDo *credentials.DetectOptions) *credentials.DetectOptions

CloneDetectOptions clones a user set detect option into some new memory that we can internally manipulate before sending onto the detect package.

func DefaultHTTPClientWithTLS ¶

func DefaultHTTPClientWithTLS(tlsConfig *tls.Config) *http.Client

DefaultHTTPClientWithTLS constructs an HTTPClient using the provided tlsConfig, to support mTLS.

func GetClientCertificateProvider ¶

func GetClientCertificateProvider(opts *Options) (cert.Provider, error)

GetClientCertificateProvider returns a default client certificate source, if not provided by the user.

A nil default source can be returned if the source does not exist. Any exceptions encountered while initializing the default source will be reported as client error (ex. corrupt metadata file).

func GetGRPCTransportCredsAndEndpoint ¶

func GetGRPCTransportCredsAndEndpoint(opts *Options) (credentials.TransportCredentials, string, error)

GetGRPCTransportCredsAndEndpoint returns an instance of google.golang.org/grpc/credentials.TransportCredentials, and the corresponding endpoint to use for GRPC client.

func GetHTTPTransportConfig ¶

func GetHTTPTransportConfig(opts *Options) (cert.Provider, func(context.Context, string, string) (net.Conn, error), error)

GetHTTPTransportConfig returns a client certificate source and a function for dialing MTLS with S2A.

func GetS2AAddress ¶

func GetS2AAddress() string

GetS2AAddress returns the S2A address to be reached via plaintext connection. Returns empty string if not set or invalid.

func ValidateUniverseDomain ¶

func ValidateUniverseDomain(clientUniverseDomain, credentialsUniverseDomain string) error

ValidateUniverseDomain verifies that the universe domain configured for the client matches the universe domain configured for the credentials.

Types ¶

type Options ¶

type Options struct {
	Endpoint                string
	DefaultMTLSEndpoint     string
	DefaultEndpointTemplate string
	ClientCertProvider      cert.Provider
	Client                  *http.Client
	UniverseDomain          string
	EnableDirectPath        bool
	EnableDirectPathXds     bool
}

Options is a struct that is duplicated information from the individual transport packages in order to avoid cyclic deps. It correlates 1:1 with fields on httptransport.Options and grpctransport.Options.
