Functions

func Compare

func Compare(a, b *container.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) (*container.Config, *container.HostConfig, *networktypes.NetworkingConfig, error)

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

func DecodeHostConfig

func DecodeHostConfig(src io.Reader) (*container.HostConfig, error)

DecodeHostConfig creates a HostConfig based on the specified Reader. It assumes the content of the reader will be JSON, and decodes it.

func DefaultDaemonNetworkMode

func DefaultDaemonNetworkMode() container.NetworkMode

DefaultDaemonNetworkMode returns the default network stack the daemon should use.

func IsPreDefinedNetwork

func IsPreDefinedNetwork(network string) bool

IsPreDefinedNetwork indicates if a network is predefined by the daemon

func SetDefaultNetModeIfBlank

func SetDefaultNetModeIfBlank(hc *container.HostConfig) *container.HostConfig

SetDefaultNetModeIfBlank changes the NetworkMode in a HostConfig structure to default if it is not populated. This ensures backwards compatibility after the validation of the network mode was moved from the docker CLI to the docker daemon.

func ValidateIsolation

func ValidateIsolation(hc *container.HostConfig) error

ValidateIsolation performs platform specific validation of isolation in the hostconfig structure. Linux only supports "default" which is LXC container isolation

func ValidateNetMode

func ValidateNetMode(c *container.Config, hc *container.HostConfig) error

ValidateNetMode ensures that the various combinations of requested network settings are valid.

func ValidateQoS

func ValidateQoS(hc *container.HostConfig) error

ValidateQoS performs platform specific validation of the QoS settings

Types

type ContainerConfigWrapper

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

ContainerConfigWrapper is a Config wrapper that holds the container Config (portable) and the corresponding HostConfig (non-portable).

type ContainerDecoder

type ContainerDecoder struct{}

ContainerDecoder implements httputils.ContainerDecoder calling DecodeContainerConfig.

func (ContainerDecoder) DecodeConfig

func (r ContainerDecoder) DecodeConfig(src io.Reader) (*container.Config, *container.HostConfig, *networktypes.NetworkingConfig, error)

DecodeConfig makes ContainerDecoder to implement httputils.ContainerDecoder

func (ContainerDecoder) DecodeHostConfig

func (r ContainerDecoder) DecodeHostConfig(src io.Reader) (*container.HostConfig, error)

DecodeHostConfig makes ContainerDecoder to implement httputils.ContainerDecoder
