Functions

func JoinDir

func JoinDir(dir, path string) string

JoinDir joins dir and path if path is relative. If path is empty or absolute, it is returned unchanged.

func NewBasicAuthRoundTripper

func NewBasicAuthRoundTripper(username string, password Secret, passwordFile string, rt http.RoundTripper) http.RoundTripper

NewBasicAuthRoundTripper will apply a BASIC auth authorization header to a request unless it has already been set.

func NewBearerAuthFileRoundTripper

func NewBearerAuthFileRoundTripper(bearerFile string, rt http.RoundTripper) http.RoundTripper

NewBearerAuthFileRoundTripper adds the bearer token read from the provided file to a request unless the authorization header has already been set. This file is read for every request.

func NewBearerAuthRoundTripper

func NewBearerAuthRoundTripper(token Secret, rt http.RoundTripper) http.RoundTripper

NewBearerAuthRoundTripper adds the provided bearer token to a request unless the authorization header has already been set.

func NewClientFromConfig

func NewClientFromConfig(cfg HTTPClientConfig, name string, disableKeepAlives, enableHTTP2 bool) (*http.Client, error)

NewClientFromConfig returns a new HTTP client configured for the given config.HTTPClientConfig. The name is used as go-conntrack metric label.

func NewRoundTripperFromConfig

func NewRoundTripperFromConfig(cfg HTTPClientConfig, name string, disableKeepAlives, enableHTTP2 bool) (http.RoundTripper, error)

NewRoundTripperFromConfig returns a new HTTP RoundTripper configured for the given config.HTTPClientConfig. The name is used as go-conntrack metric label.

func NewTLSConfig

func NewTLSConfig(cfg *TLSConfig) (*tls.Config, error)

NewTLSConfig creates a new tls.Config from the given TLSConfig.

Types

type BasicAuth

type BasicAuth struct {
	Username     string `yaml:"username"`
	Password     Secret `yaml:"password,omitempty"`
	PasswordFile string `yaml:"password_file,omitempty"`
}

BasicAuth contains basic HTTP authentication credentials.

func (*BasicAuth) SetDirectory

func (a *BasicAuth) SetDirectory(dir string)

SetDirectory joins any relative file paths with dir.

func (*BasicAuth) UnmarshalYAML

func (a *BasicAuth) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements the yaml.Unmarshaler interface.

type DirectorySetter

type DirectorySetter interface {
	// SetDirectory joins any relative file paths with dir.
	// Any paths that are empty or absolute remain unchanged.
	SetDirectory(dir string)
}

DirectorySetter is a config type that contains file paths that may be relative to the file containing the config.

type HTTPClientConfig

type HTTPClientConfig struct {
	// The HTTP basic authentication credentials for the targets.
	BasicAuth *BasicAuth `yaml:"basic_auth,omitempty"`
