Constants ¶
const DefaultHTTPHost = "localhost"
DefaultHTTPHost Default HTTP Host used if only port is provided to -H flag e.g. dockerd -H tcp://:8080
Variables ¶
var ( // DefaultHTTPPort Default HTTP Port used if only the protocol is provided to -H flag e.g. dockerd -H tcp:// // 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/balena-engine.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) // DefaultNamedPipe defines the default named pipe used by docker on Windows DefaultNamedPipe = `//./pipe/docker_engine` )
var DefaultHost = fmt.Sprintf("unix://%s", DefaultUnixSocket)
DefaultHost constant defines the default host string used by docker on other hosts than Windows
Functions ¶
func ParseTCPAddr ¶
ParseTCPAddr parses and validates that the specified address is a valid TCP address. It returns a formatted TCP address, either using the address parsed from tryAddr, or the contents of defaultAddr if tryAddr is a blank string. tryAddr is expected to have already been Trim()'d defaultAddr must be in the full `tcp://host:port` form
func ValidateDNSSearch ¶
ValidateDNSSearch validates domain for resolvconf search configuration. A zero length domain is represented by a dot (.).
func ValidateEnv ¶
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.
The only validation here is to check if name is empty, per #25099
func ValidateExtraHost ¶
ValidateExtraHost validates that the specified string is a valid extrahost and returns it. ExtraHost is in the form of name:ip where the ip has to be a valid ip (IPv4 or IPv6).
func ValidateHost ¶
ValidateHost validates that the specified string is a valid host and returns it.
func ValidateIPAddress ¶
ValidateIPAddress validates an Ip address.
func ValidateLabel ¶
ValidateLabel validates that the specified string is a valid label, and returns it. Labels are in the form on key=value.
func ValidateSingleGenericResource ¶
ValidateSingleGenericResource validates that a single entry in the generic resource list is valid. i.e 'GPU=UID1' is valid however 'GPU:UID1' or 'UID1' isn't
Types ¶
type IPOpt ¶
IPOpt holds an IP. It is used to store values from CLI flags.
func NewIPOpt ¶
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 ¶
Set sets an IPv4 or IPv6 address from a given string. If the given string is not parsable as an IP address it returns an error.
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) GetAllOrEmpty ¶
GetAllOrEmpty returns the values of the slice or an empty slice when there are no values.
func (*ListOpts) GetMap ¶
GetMap returns the content of values in a map in order to avoid duplicates.
func (*ListOpts) WithValidator ¶
func (opts *ListOpts) WithValidator(validator ValidatorFctType) *ListOpts
WithValidator returns the ListOpts with validator set.
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.
type MemBytes ¶
type MemBytes int64
MemBytes is a type for human readable memory bytes (like 128M, 2g, etc)
func (*MemBytes) UnmarshalJSON ¶
UnmarshalJSON is the customized unmarshaler for MemBytes
type NamedListOpts ¶
type NamedListOpts struct {
