Functions ¶
func ChooseBindAddress ¶
func ChooseBindAddress(bindAddress net.IP) (net.IP, error)
If bind-address is usable, return it directly If bind-address is not usable (unset, 0.0.0.0, or loopback), we will use the host's default interface.
func ChooseHostInterface ¶
func ChooseHostInterface() (net.IP, error)
ChooseHostInterface is a method used fetch an IP for a daemon. It uses data from /proc/net/route file. For a node with no internet connection ,it returns error For a multi n/w interface node it returns the IP of the interface with gateway on it.
func CloneTLSConfig ¶ added in v1.4.0
func CloneTLSConfig(cfg *tls.Config) *tls.Config
CloneTLSConfig returns a tls.Config with all exported fields except SessionTicketsDisabled and SessionTicketKey copied. This makes it safe to call CloneTLSConfig on a config in active use by a server. TODO: replace with tls.Config#Clone when we move to go1.8
func GetClientIP ¶
func GetClientIP(req *http.Request) net.IP
Extracts and returns the clients IP from the given request. Looks at X-Forwarded-For header, X-Real-Ip header and request.RemoteAddr in that order. Returns nil if none of them are set or is set to an invalid value.
func GetHTTPClient ¶
func GetHTTPClient(req *http.Request) string
func IPNetEqual ¶ added in v1.3.0
func IPNetEqual(ipnet1, ipnet2 *net.IPNet) bool
IPNetEqual checks if the two input IPNets are representing the same subnet. For example,
10.0.0.1/24 and 10.0.0.0/24 are the same subnet.
10.0.0.1/24 and 10.0.0.0/25 are not the same subnet.
func IsProbableEOF ¶
func IsProbableEOF(err error) bool
IsProbableEOF returns true if the given error resembles a connection termination scenario that would justify assuming that the watch is empty. These errors are what the Go http stack returns back to us which are general connection closure errors (strongly correlated) and callers that need to differentiate probable errors in connection behavior between normal "this is disconnected" should use the method.
func JoinSchemeNamePort ¶
func JoinSchemeNamePort(scheme, name, port string) string
JoinSchemeNamePort returns a string that specifies the scheme, name, and port:
- "<name>"
- "<name>:<port>"
- "<scheme>:<name>:<port>"
None of the parameters may contain a ':' character Name is required Scheme must be "", "http", or "https"
func NewProxierWithNoProxyCIDR ¶ added in v1.3.0
func NewProxierWithNoProxyCIDR(delegate func(req *http.Request) (*url.URL, error)) func(req *http.Request) (*url.URL, error)
NewProxierWithNoProxyCIDR constructs a Proxier function that respects CIDRs in NO_PROXY and delegates if no matching CIDRs are found
func SetOldTransportDefaults ¶ added in v1.3.0
func SetOldTransportDefaults(t *http.Transport) *http.Transport
SetOldTransportDefaults applies the defaults from http.DefaultTransport for the Proxy, Dial, and TLSHandshakeTimeout fields if unset
func SetTransportDefaults ¶
func SetTransportDefaults(t *http.Transport) *http.Transport
SetTransportDefaults applies the defaults from http.DefaultTransport for the Proxy, Dial, and TLSHandshakeTimeout fields if unset
func SplitSchemeNamePort ¶
func SplitSchemeNamePort(id string) (scheme, name, port string, valid bool)
SplitSchemeNamePort takes a string of the following forms:
- "<name>", returns "", "<name>","", true
- "<name>:<port>", returns "", "<name>","<port>",true
- "<scheme>:<name>:<port>", returns "<scheme>","<name>","<port>",true
Name must be non-empty or valid will be returned false. Scheme must be "http" or "https" if specified Port is returned as a string, and it is not required to be numeric (could be used for a named port, for example).
func TLSClientConfig ¶
func TLSClientConfig(transport http.RoundTripper) (*tls.Config, error)
Types ¶
type PortRange ¶
type PortRange struct {
Base int
Size int
}
PortRange represents a range of TCP/UDP ports. To represent a single port, set Size to 1.
func ParsePortRange ¶
func ParsePortRange(value string) (*PortRange, error)
ParsePortRange parses a string of the form "min-max", inclusive at both ends, and initializs a new PortRange from it.
func ParsePortRangeOrDie ¶
func ParsePortRangeOrDie(value string) *PortRange
func (*PortRange) Contains ¶
func (pr *PortRange) Contains(p int) bool
Contains tests whether a given port falls within the PortRange.
func (*PortRange) Set ¶
func (pr *PortRange) Set(value string) error
Set parses a string of the form "min-max", inclusive at both ends, and sets the PortRange from it. This is part of the flag.Value and pflag.Value interfaces.
type RoundTripperWrapper ¶
type RoundTripperWrapper interface {
http.RoundTripper
WrappedRoundTripper() http.RoundTripper
}
