Constants ¶

Functions ¶
func NewDirectory ¶
NewDirectory creates a new directory for the container name in the directory identified by `ContainerDir`.
func RemoveDirectory ¶
RemoveDirectory moves the container directory from `ContainerDir` to `RemovedContainerDir` and makes sure that the names don't clash.
func WriteCloudInitFile ¶
WriteCloudInitFile writes the data out to a cloud-init file in the directory specified, and returns the filename.
func WriteUserData ¶
func WriteUserData(machineConfig *cloudinit.MachineConfig, directory string) (string, error)
WriteUserData generates the cloud init for the specified machine config, and writes the serialized form out to a cloud-init file in the directory specified.
Types ¶
type Initialiser ¶
type Initialiser interface {
// Initialise installs all required packages, sync any images etc so
// that the host machine can run containers.
Initialise() error
}
Initialiser is responsible for performing the steps required to initialise a host machine so it can run containers.
type Manager ¶
type Manager interface {
// CreateContainer creates and starts a new container for the specified
// machine.
CreateContainer(
machineConfig *cloudinit.MachineConfig,
series string,
network *NetworkConfig) (instance.Instance, *instance.HardwareCharacteristics, error)
// DestroyContainer stops and destroyes the container identified by
// instance id.
DestroyContainer(instance.Id) error
// ListContainers return a list of containers that have been started by
// this manager.
ListContainers() ([]instance.Instance, error)
}
Manager is responsible for starting containers, and stopping and listing containers that it has started.
type ManagerConfig ¶
ManagerConfig contains the initialization parameters for the ContainerManager. The name of the manager is used to namespace the containers on the machine.
func (ManagerConfig) PopValue ¶
func (m ManagerConfig) PopValue(key string) string
PopValue returns the requested key from the config map. If the value doesn't exist, the function returns the empty string. If the value does exist, the value is returned, and the element removed from the map.
func (ManagerConfig) WarnAboutUnused ¶
func (m ManagerConfig) WarnAboutUnused()
WarnAboutUnused emits a warning about each value in the map.
type NetworkConfig ¶
NetworkConfig defines how the container network will be configured.
func BridgeNetworkConfig ¶
func BridgeNetworkConfig(device string) *NetworkConfig
BridgeNetworkConfig returns a valid NetworkConfig to use the specified device as a network bridge for the container.
func PhysicalNetworkConfig ¶
func PhysicalNetworkConfig(device string) *NetworkConfig
PhysicalNetworkConfig returns a valid NetworkConfig to use the specified device as the network device for the container.
