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 Merge

func Merge(userConf, imageConf *Config) error

func Parse

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

Types

type Config

type Config struct {
	Hostname        string
	Domainname      string
	User            string
	Memory          int64  // Memory limit (in bytes)
	MemorySwap      int64  // Total memory usage (memory + swap); set `-1' to disable swap
	CpuShares       int64  // CPU shares (relative weight vs. other containers)
	Cpuset          string // Cpuset 0-2, 0,1
	AttachStdin     bool
	AttachStdout    bool
	AttachStderr    bool
	PortSpecs       []string // Deprecated - Can be in the format of 8080/tcp
	ExposedPorts    map[nat.Port]struct{}
	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             []string
	Image           string // Name of the image as it was passed by the operator (eg. could be symbolic)
	Volumes         map[string]struct{}
	WorkingDir      string
	Entrypoint      []string
	NetworkDisabled bool
	MacAddress      string
	OnBuild         []string
	SecurityOpt     []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.

func ContainerConfigFromJob

func ContainerConfigFromJob(job *engine.Job) *Config

type ConfigAndHostConfig

type ConfigAndHostConfig struct {
	Config
	HostConfig HostConfig
}

This is used by the create command when you want to set both the Config and the HostConfig in the same call

func MergeConfigs

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

type DeviceMapping

type DeviceMapping struct {
	PathOnHost        string
	PathInContainer   string
	CgroupPermissions string
}

func ParseDevice

func ParseDevice(device string) (DeviceMapping, error)

	User         string
	Privileged   bool
	Tty          bool
	Container    string
	AttachStdin  bool
	AttachStderr bool
	AttachStdout bool
	Detach       bool
	Cmd          []string
}

func ExecConfigFromJob

func ExecConfigFromJob(job *engine.Job) *ExecConfig

func ParseExec

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

type HostConfig

	Links           []string
	PublishAllPorts bool
	Dns             []string
	DnsSearch       []string
	ExtraHosts      []string
	VolumesFrom     []string
	Devices         []DeviceMapping
	NetworkMode     NetworkMode
	IpcMode         IpcMode
	CapAdd          []string
	CapDrop         []string
	RestartPolicy   RestartPolicy
}
