Functions

func Compare 

func Compare(a, b *Config) bool

Compare two Config struct. Do not compare the "Image" nor "Hostname" fields If OpenStdin is set, then it differs

func DecodeContainerConfig 

func DecodeContainerConfig(src io.Reader) (*Config, *HostConfig, error)

DecodeContainerConfig decodes a json encoded config into a ContainerConfigWrapper struct and returns both a Config and an HostConfig struct Be aware this function is not checking whether the resulted structs are nil, it's your business to do so

func Merge 

func Merge(userConf, imageConf *Config) error

func Parse 

func Parse(cmd *flag.FlagSet, args []string) (*Config, *HostConfig, *flag.FlagSet, error)

type Config 

type Config struct {
	Hostname        string                // Hostname
	Domainname      string                // Domainname
	User            string                // User that will run the command(s) inside the container
	AttachStdin     bool                  // Attach the standard input, makes possible user interaction
	AttachStdout    bool                  // Attach the standard output
	AttachStderr    bool                  // Attach the standard error
	ExposedPorts    map[nat.Port]struct{} `json:",omitempty"` // List of exposed ports
	PublishService  string                `json:",omitempty"` // Name of the network service exposed by the container
	Tty             bool                  // Attach standard streams to a tty, including stdin if it is not closed.
	OpenStdin       bool                  // Open stdin
	StdinOnce       bool                  // If true, close stdin after the 1 attached client disconnects.
	Env             []string              // List of environment variable to set in the container
	Cmd             *Command              // Command to run when starting the container
	Image           string                // Name of the image as it was passed by the operator (eg. could be symbolic)
	Volumes         map[string]struct{}   // List of volumes (mounts) used for the container
	VolumeDriver    string                `json:",omitempty"` // Name of the volume driver used to mount volumes
	WorkingDir      string                // Current directory (PWD) in the command will be launched
	Entrypoint      *Entrypoint           // Entrypoint to run when starting the container
	NetworkDisabled bool                  `json:",omitempty"` // Is network disabled
	MacAddress      string                `json:",omitempty"` // Mac Address of the container
	OnBuild         []string              // ONBUILD metadata that were defined on the image Dockerfile
	Labels          map[string]string     // List of labels set to this container
}

Note: the Config structure should hold only portable information about the container. Here, "portable" means "independent from the host we are running on". Non-portable information *should* appear in HostConfig. All fields added to this struct must be marked `omitempty` to keep getting predictable hashes from the old `v1Compatibility` configuration.

type ContainerConfigWrapper 

type ContainerConfigWrapper struct {
	*Config
	InnerHostConfig *HostConfig `json:"HostConfig,omitempty"`
	Cpuset          string      `json:",omitempty"` // Deprecated. Exported for backwards compatibility.
	*HostConfig                 // Deprecated. Exported to read attrubutes from json that are not in the inner host config structure.

}

type Entrypoint 

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

Entrypoint encapsulates the container entrypoint. It might be represented as a string or an array of strings. We need to override the json decoder to accept both options. The JSON decoder will fail if the api sends an string and 

we try to decode it into an array of string.

func NewEntrypoint

func (*Entrypoint) UnmarshalJSON 

func (e *Entrypoint) UnmarshalJSON(b []byte) error

UnmarshalJSON decoded the entrypoint whether it's a string or an array of strings.
