Variables 

var (

	// DefaultHTTPHost Default HTTP Host used if only port is provided to -H flag e.g. docker daemon -H tcp://:8080
	DefaultHTTPHost = "localhost"

	// DefaultHTTPPort Default HTTP Port used if only the protocol is provided to -H flag e.g. docker daemon -H tcp://
	// TODO Windows. DefaultHTTPPort is only used on Windows if a -H parameter
	// is not supplied. A better longer term solution would be to use a named
	// pipe as the default on the Windows daemon.
	// These are the IANA registered port numbers for use with Docker
	// see http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?search=docker
	DefaultHTTPPort = 2375 // Default HTTP Port
	// DefaultTLSHTTPPort Default HTTP Port used when TLS enabled
	DefaultTLSHTTPPort = 2376 // Default TLS encrypted HTTP Port
	// DefaultUnixSocket Path for the unix socket.
	// Docker daemon by default always listens on the default unix socket
	DefaultUnixSocket = "/var/run/docker.sock"
	// DefaultTCPHost constant defines the default host string used by docker on Windows
	DefaultTCPHost = fmt.Sprintf("tcp://%s:%d", DefaultHTTPHost, DefaultHTTPPort)
	// DefaultTLSHost constant defines the default host string used by docker for TLS sockets
	DefaultTLSHost = fmt.Sprintf("tcp://%s:%d", DefaultHTTPHost, DefaultTLSHTTPPort)
)
var DefaultHost = fmt.Sprintf("unix://%s", DefaultUnixSocket)

DefaultHost constant defines the default host string used by docker on other hosts than Windows

Functions

func ParseEnvFile 

func ParseEnvFile(filename string) ([]string, error)

ParseEnvFile reads a file with environment variables enumerated by lines

“Environment variable names used by the utilities in the Shell and Utilities volume of IEEE Std 1003.1-2001 consist solely of uppercase letters, digits, and the '_' (underscore) from the characters defined in Portable Character Set and do not begin with a digit. *But*, other characters may be permitted by an implementation; applications shall tolerate the presence of such names.” -- http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap08.html

As of #16585, it's up to application inside docker to validate or not environment variables, that's why we just strip leading whitespace and nothing more.

func ParseHost 

func ParseHost(defaultHost, val string) (string, error)

ParseHost and set defaults for a Daemon host string

func ValidDeviceMode 

func ValidDeviceMode(mode string) bool

ValidDeviceMode checks if the mode for device is valid or not. Valid mode is a composition of r (read), w (write), and m (mknod).

func ValidateAttach 

func ValidateAttach(val string) (string, error)

ValidateAttach validates that the specified string is a valid attach option.

func ValidateDNSSearch 

func ValidateDNSSearch(val string) (string, error)

ValidateDNSSearch validates domain for resolvconf search configuration. A zero length domain is represented by a dot (.).

func ValidateDevice 

func ValidateDevice(val string) (string, error)

ValidateDevice validates a path for devices It will make sure 'val' is in the form: 

[host-dir:]container-path[:mode]

It also validates the device mode.

func ValidateEnv 

func ValidateEnv(val string) (string, error)

ValidateEnv validates an environment variable and returns it. If no value is specified, it returns the current value using os.Getenv.

As on ParseEnvFile and related to #16585, environment variable names are not validate what so ever, it's up to application inside docker to validate them or not.

func ValidateExtraHost 

func ValidateExtraHost(val string) (string, error)

ValidateExtraHost validates that the specified string is a valid extrahost and returns it. ExtraHost are in the form of name:ip where the ip has to be a valid ip (ipv4 or ipv6).

func ValidateHost 

func ValidateHost(val string) (string, error)

ValidateHost validates that the specified string is a valid host and returns it.

func ValidateIPAddress 

func ValidateIPAddress(val string) (string, error)

ValidateIPAddress validates an Ip address.

func ValidateLabel 

func ValidateLabel(val string) (string, error)

ValidateLabel validates that the specified string is a valid label, and returns it. Labels are in the form on key=value. 

func ValidateLink(val string) (string, error)

ValidateLink validates that the specified string has a valid link format (containerName:alias).

func ValidateMACAddress 

func ValidateMACAddress(val string) (string, error)

ValidateMACAddress validates a MAC address.

func ValidatePath 

func ValidatePath(val string) (string, error)

ValidatePath validates a path for volumes It will make sure 'val' is in the form: 

[host-dir:]container-path[:rw|ro]

It also validates the mount mode.
