type Driver ¶
type Driver interface { Run(c *Command, pipes *Pipes, startCallback StartCallback) (int, error) // Run executes the process and blocks until the process exits and returns the exit code // Exec executes the process in an existing container, blocks until the process exits and returns the exit code Exec(c *Command, processConfig *ProcessConfig, pipes *Pipes, startCallback StartCallback) (int, error) Kill(c *Command, sig int) error Pause(c *Command) error Unpause(c *Command) error Name() string // Driver name Info(id string) Info // "temporary" hack (until we move state from core to plugins) GetPidsForContainer(id string) ([]int, error) // Returns a list of pids for the given container. Terminate(c *Command) error // kill it with fire Clean(id string) error // clean all traces of container exec Parent() string }
type Info ¶
type Info interface {
IsRunning() bool
}
Driver specific information based on processes registered with the driver
type Network ¶
