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)

Types

type Command

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

func NewCommand

func NewCommand(parts ...string) *Command

func (*Command) Len

func (e *Command) Len() int

func (*Command) MarshalJSON

func (e *Command) MarshalJSON() ([]byte, error)

func (*Command) Slice

func (e *Command) Slice() []string

func (*Command) ToString

func (e *Command) ToString() string

func (*Command) UnmarshalJSON

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

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

type Config

type Config struct {
	Hostname        string
	Domainname      string
	User            string
	AttachStdin     bool
	AttachStdout    bool
	AttachStderr    bool
	ExposedPorts    map[nat.Port]struct{}
	PublishService  string
	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
	Cmd             *Command
	Image           string // Name of the image as it was passed by the operator (eg. could be symbolic)
	Volumes         map[string]struct{}
	VolumeDriver    string
	WorkingDir      string
	Entrypoint      *Entrypoint
	NetworkDisabled bool
	MacAddress      string
	OnBuild         []string
	Labels          map[string]string
}

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.

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.

}

func MergeConfigs

func MergeConfigs(config *Config, hostConfig *HostConfig) *ContainerConfigWrapper

func (*ContainerConfigWrapper) GetHostConfig

func (w *ContainerConfigWrapper) GetHostConfig() *HostConfig

type DeviceMapping

type DeviceMapping struct {
	PathOnHost        string
	PathInContainer   string
	CgroupPermissions string
}

func ParseDevice

func ParseDevice(device string) (DeviceMapping, error)

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 NewEntrypoint(parts ...string) *Entrypoint

func (*Entrypoint) Len

func (e *Entrypoint) Len() int

func (*Entrypoint) MarshalJSON

func (e *Entrypoint) MarshalJSON() ([]byte, error)

func (*Entrypoint) Slice

func (e *Entrypoint) Slice() []string

func (*Entrypoint) UnmarshalJSON

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

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

type ExecConfig struct {
	User         string
	Privileged   bool
	Tty          bool
	Container    string
	AttachStdin  bool
	AttachStderr bool
	AttachStdout bool
	Detach       bool
	Cmd          []string
}

func ParseExec

func ParseExec(cmd *flag.FlagSet, args []string) (*ExecConfig, error)

	CpuShares       int64 // CPU shares (relative weight vs. other containers)
	CpuPeriod       int64
	CpusetCpus      string // CpusetCpus 0-2, 0,1
	CpusetMems      string // CpusetMems 0-2, 0,1
	CpuQuota        int64
	BlkioWeight     int64 // Block IO weight (relative weight vs. other containers)
	OomKillDisable  bool  // Whether to disable OOM Killer or not
	Privileged      bool
	PortBindings    nat.PortMap
	Links           []string
	PublishAllPorts bool
