Package ansible is providing data structures and functions for responses when rocker-compose is running in ansible mode (rocker-compose run --ansible).

Package config holds functionality for processing compose.yml manifests, templating, converting manifests to docker api run spec and comparing them against each other.

GetBridgeIP gets the ip address of docker network bridge it is useful when you want to loose couple containers and not have tightly link them container A may publish port 8125 to host network and container B may access this port through a bridge ip address; it's a hacky solution, any better way to obtain bridge ip without ssh access to host machine is welcome Here we create a dummy container and look at .NetworkSettings.Gateway value TODO: maybe we don't need this anymore since docker 1.8 seem to specify all existing containers in a /etc/hosts file of every contianer.

GetContainersFromConfig returns the list of Container objects from a spec Config object.

New makes a new Compose object.

NewClient makes a new DockerClient object based on configuration params that is given with input DockerClient object.

NewContainerFormatter returns an object that is given to logrus to better format contaienr output.

NewContainerFromConfig makes a single Container object from a spec Config object.

NewContainerFromDocker converts a container object given by docker client to a local Container object.

NewContainerIo makes ContainerIo objects and initializes formatters for container's stdout and stderr streams.

NewDiff returns an implementation of Diff object.

NewDockerClientRunner makes a runner that uses a DockerClient for executing actions.

NewDryRunner makes a runner that does not actually execute actions, but prints them.

NewEnsureContainerExistAction makes action that ensures that container exists.

NewEnsureContainerStateAction makes action that ensures that container state is a desired one.

NewRemoveContainerAction makes action that removes a container.

NewRunContainerAction makes action that runs a container.

NewStepAction makes a "step" wrapper which holds the list of actions that may run in parallel.

NewWaitContainerAction makes action that waits for container.

PullDockerImage pulls an image and streams to a logger respecting terminal features.

WalkActions recursively though all action and applies given function to every action.

NoAction is an empty action which does nothing.

Compose is the main object that executes actions and holds runtime information.

Config is a configuration object which is passed to compose.New() for creating the new Compose instance.

Container object represents a single container produced by a rocker-compose spec.

ContainerIo initializes and maintains container I/O and also owns 'done' channel that can be used by other actors.

ContainerState represents the state of a container.

DockerClient is an implementation of Client interface that do operations to a given docker client.

ErrContainerBadState is an error that describes state inconsistency that can be checked by EnsureContainerState function.

Action interface describes action that can be done by rocker-compose docker client.

Client interface describes a rocker-compose client that can do various operations needed for rocker-compose to make changes.

Diff describes a comparison functionality of two container sets: expected and actual 'expected' is a list of containers from a spec (compose.yml) 'actual' is a list of existing containers in a docker daemon The Diff function should return the action list that is needed to transition form the 'actual' state to the 'expected' one.

Runner interface describes a runnable facade which executes given list of actions.
