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, sysInfo *sysinfo.SysInfo) (*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
	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)

type ExecConfig

type ExecConfig struct {
	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

type HostConfig struct {
	Binds           []string
	ContainerIDFile string
	LxcConf         []utils.KeyValuePair
	Privileged      bool
	PortBindings    nat.PortMap
	Links           []string
	PublishAllPorts bool
	Dns             []string
	DnsSearch       []string
	ExtraHosts      []string
	VolumesFrom     []string
	Devices         []DeviceMapping
	NetworkMode     NetworkMode
	CapAdd          []string
	CapDrop         []string
	RestartPolicy   RestartPolicy
}

func ContainerHostConfigFromJob

func ContainerHostConfigFromJob(job *engine.Job) *HostConfig

type NetworkMode

type NetworkMode string

func (NetworkMode) IsContainer

func (n NetworkMode) IsContainer() bool

func (NetworkMode) IsHost

func (n NetworkMode) IsHost() bool

func (NetworkMode) IsNone

func (n NetworkMode) IsNone() bool

func (NetworkMode) IsPrivate

func (n NetworkMode) IsPrivate() bool

IsPrivate indicates whether container use it's private network stack

type RestartPolicy

type RestartPolicy struct {
	Name              string
	MaximumRetryCount int
}
