Functions ¶
Types ¶
type ACKind ¶
type ACKind string
ACKind wraps a string to define a field which must be set with one of several ACKind values. If it is unset, or has an invalid value, the field will refuse to marshal/unmarshal.
func (ACKind) MarshalJSON ¶
func (*ACKind) UnmarshalJSON ¶
type ACKindError ¶
type ACKindError string
An ACKindError is returned when the wrong ACKind is set in a manifest
func (ACKindError) Error ¶
func (e ACKindError) Error() string
type ACName ¶
type ACName string
ACName (an App-Container Name) is a format used by keys in different formats of the App Container Standard. An ACName is restricted to characters accepted by the DNS RFC[1] and "/"; all alphabetical characters must be lowercase only.
[1] http://tools.ietf.org/html/rfc1123#page-13
func NewACName ¶
NewACName generates a new ACName from a string. If the given string is not a valid ACName, nil and an error are returned.
func (*ACName) MarshalJSON ¶
MarshalJSON implements the json.Marshaler interface
func (*ACName) UnmarshalJSON ¶
UnmarshalJSON implements the json.Unmarshaler interface
type ACNameError ¶
type ACNameError string
An ACNameError is returned when a bad value is used for an ACName
func (ACNameError) Error ¶
func (e ACNameError) Error() string
type ACVersionError ¶
type ACVersionError string
An ACVersionError is returned when a bad ACVersion is set in a manifest
func (ACVersionError) Error ¶
func (e ACVersionError) Error() string
type AMStartedOnError ¶
type AMStartedOnError string
An AMStartedOnError is returned when the wrong StartedOn is set in an ImageManifest
func (AMStartedOnError) Error ¶
func (e AMStartedOnError) Error() string
type Annotation ¶ added in v0.2.0
type Annotations ¶
type Annotations []Annotation
func (Annotations) Get ¶ added in v0.2.0
func (a Annotations) Get(name string) (val string, ok bool)
Retrieve the value of an annotation by the given name from Annotations, if it exists.
func (Annotations) MarshalJSON ¶
func (a Annotations) MarshalJSON() ([]byte, error)
func (*Annotations) Set ¶ added in v0.2.0
func (a *Annotations) Set(name ACName, value string)
Set sets the value of an annotation by the given name, overwriting if one already exists.
func (*Annotations) UnmarshalJSON ¶
func (a *Annotations) UnmarshalJSON(data []byte) error
type App ¶
type App struct { Exec Exec `json:"exec"` EventHandlers []EventHandler `json:"eventHandlers,omitempty"` User string `json:"user"` Group string `json:"group"` WorkingDirectory string `json:"workingDirectory,omitempty"` Environment Environment `json:"environment,omitempty"` MountPoints []MountPoint `json:"mountPoints,omitempty"` Ports []Port `json:"ports,omitempty"` Isolators []Isolator `json:"isolators,omitempty"` }
func (App) MarshalJSON ¶
func (*App) UnmarshalJSON ¶
type Date ¶
Date wraps time.Time to marshal/unmarshal to/from JSON strings in strict accordance with RFC3339 TODO(jonboulle): golang's implementation seems slightly buggy here; according to http://tools.ietf.org/html/rfc3339#section-5.6 , applications may choose to separate the date and time with a space instead of a T character (for example, `date --rfc-3339` on GNU coreutils) - but this is considered an error by go's parser. File a bug?
func (Date) MarshalJSON ¶
func (*Date) UnmarshalJSON ¶
type Dependencies ¶
type Dependencies []Dependency
type Dependency ¶
type Dependency struct { App ACName `json:"app"` ImageID *Hash `json:"imageID,omitempty"` Labels Labels `json:"labels,omitempty"` }
func (Dependency) MarshalJSON ¶
func (d Dependency) MarshalJSON() ([]byte, error)
func (*Dependency) UnmarshalJSON ¶
func (d *Dependency) UnmarshalJSON(data []byte) error
type Environment ¶ added in v0.3.0
type Environment []EnvironmentVariable
func (Environment) Get ¶ added in v0.3.0
func (e Environment) Get(name string) (value string, ok bool)
Retrieve the value of an environment variable by the given name from Environment, if it exists.
func (Environment) MarshalJSON ¶ added in v0.3.0
func (e Environment) MarshalJSON() ([]byte, error)
func (*Environment) Set ¶ added in v0.3.0
func (e *Environment) Set(name string, value string)
Set sets the value of an environment variable by the given name, overwriting if one already exists.
func (*Environment) UnmarshalJSON ¶ added in v0.3.0
func (e *Environment) UnmarshalJSON(data []byte) error
type EnvironmentVariable ¶ added in v0.3.0
type EventHandler ¶
func (EventHandler) MarshalJSON ¶
func (e EventHandler) MarshalJSON() ([]byte, error)

type Exec []string
func (Exec) MarshalJSON ¶ added in v0.2.0
func (*Exec) UnmarshalJSON ¶ added in v0.2.0
type Hash ¶
type Hash struct { Val string // contains filtered or unexported fields }
Hash encodes a hash specified in a string of the form:
"<type>-<value>"
for example
"sha512-06c733b1838136838e6d2d3e8fa5aea4c7905e92[...]"
Valid types are currently:
- sha512

type SemVer ¶
SemVer implements the Unmarshaler interface to define a field that must be a semantic version string TODO(jonboulle): extend upstream instead of wrapping?
func NewSemVer ¶
NewSemVer generates a new SemVer from a string. If the given string does not represent a valid SemVer, nil and an error are returned.
func (SemVer) MarshalJSON ¶
MarshalJSON implements the json.Marshaler interface

type UUID ¶
type UUID [16]byte
UUID encodes an RFC4122-compliant UUID, marshaled to/from a string TODO(jonboulle): vendor a package for this? TODO(jonboulle): consider more flexibility in input string formats. Right now, we only accept:
"6733C088-A507-4694-AABF-EDBE4FC5266F" "6733C088A5074694AABFEDBE4FC5266F"
