Constants

const DefaultHTTPHost = "localhost"

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

Variables

var (
	// 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

var DefaultHost = fmt.Sprintf("unix://%s", DefaultUnixSocket)

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

Functions

func ParseHost

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

ParseHost and set defaults for a Daemon host string

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 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.

Types

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

func (o *IPOpt) Set(val string) error

Set sets an IPv4 or IPv6 address from a given string. If the given string is not parseable as an IP address it returns an error.

func (*IPOpt) String

func (o *IPOpt) String() string

String returns the IP address stored in the IPOpt. If stored IP is a nil pointer, it returns an empty string.

type ListOpts

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

ListOpts holds a list of values and a validation function.

func NewListOpts

func NewListOpts(validator ValidatorFctType) ListOpts

NewListOpts creates a new ListOpts with the specified validator.

func NewListOptsRef

func NewListOptsRef(values *[]string, validator ValidatorFctType) *ListOpts

NewListOptsRef creates a new ListOpts with the specified values and validator.

func (*ListOpts) Delete

func (opts *ListOpts) Delete(key string)

Delete removes the specified element from the slice.

func (*ListOpts) Get

func (opts *ListOpts) Get(key string) bool

Get checks the existence of the specified key.

func (*ListOpts) GetAll

func (opts *ListOpts) GetAll() []string

GetAll returns the values of slice.

func (*ListOpts) GetAllOrEmpty

func (opts *ListOpts) GetAllOrEmpty() []string

GetAllOrEmpty returns the values of the slice or an empty slice when there are no values.

func (*ListOpts) GetMap

func (opts *ListOpts) GetMap() map[string]struct{}

GetMap returns the content of values in a map in order to avoid duplicates.

func (*ListOpts) Len

func (opts *ListOpts) Len() int

Len returns the amount of element in the slice.

func (*ListOpts) Set

func (opts *ListOpts) Set(value string) error

Set validates if needed the input value and add it to the internal slice.

func (*ListOpts) String

func (opts *ListOpts) String() string

type MapOpts

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

MapOpts holds a map of values and a validation function.

func NewMapOpts

func NewMapOpts(values map[string]string, validator ValidatorFctType) *MapOpts

NewMapOpts creates a new MapOpts with the specified map of values and a validator.

func (*MapOpts) GetAll

func (opts *MapOpts) GetAll() map[string]string

GetAll returns the values of MapOpts as a map.

func (*MapOpts) Set

func (opts *MapOpts) Set(value string) error

Set validates if needed the input value and add it to the internal map, by splitting on '='.

func (*MapOpts) String

func (opts *MapOpts) String() string

type ValidatorFctListType

type ValidatorFctListType func(val string) ([]string, error)

ValidatorFctListType defines a validator function that returns a validated list of string and/or an error

type ValidatorFctType

type ValidatorFctType func(val string) (string, error)

ValidatorFctType defines a validator function that returns a validated string and/or an error.
