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

ParseEnvFile reads a file with environment variables enumerated by lines

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(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. It uses EnvironmentVariableRegexp to ensure the name of the environment variable is valid. If no value is specified, it returns the current value using os.Getenv.

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.

Types

type ErrBadEnvVariable

type ErrBadEnvVariable struct {
	// contains filtered or unexported fields
}

ErrBadEnvVariable typed error for bad environment variable

func (ErrBadEnvVariable) Error

type IPOpt

type IPOpt struct {
	*net.IP

IPOpt holds an IP. It is used to store values from CLI flags.

func NewIPOpt

func NewIPOpt(ref *net.IP, defaultVal string) *IPOpt

NewIPOpt creates a new IPOpt from a reference net.IP and a string representation of an IP. If the string is not a valid IP it will fallback to the specified reference.

func (*IPOpt) Set
