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 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 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 ValidateMACAddress

func ValidateMACAddress(val string) (string, error)

ValidateMACAddress validates a MAC address.

func ValidateThrottleBpsDevice

func ValidateThrottleBpsDevice(val string) (*blkiodev.ThrottleDevice, error)

ValidateThrottleBpsDevice validates that the specified string has a valid device-rate format.

func ValidateThrottleIOpsDevice

func ValidateThrottleIOpsDevice(val string) (*blkiodev.ThrottleDevice, error)
