Constructor Details

#initialize(machine_spec, transport, convergence_strategy, connection, command = nil) ⇒ DockerContainerMachine

Expects a machine specification, a usable transport and convergence strategy Options is expected to contain the optional keys

:command => the final command to execute
:ports => a list of port numbers to listen on
