Currently Shipyard is attempting to retrieve Tiller information to pass to Armada. Once the dependent change is merged, Tiller will be moved into the same pod as Armada, and this information will be retrieved from the Armada configuration file. Therefore, Shipyard should no longer be retrieving this information for Armada.

Shipyard
Shipyard is the directed acyclic graph controller for Kubernetes and OpenStack control plane life cycle management, and a component of the Airship Undercloud Platform (UCP).
Shipyard provides the entrypoint for the following aspects of the control plane established by the Airship:
- Designs and Secrets
-
Site designs, including the configuration of bare metal host
nodes, network design, operating systems, Kubernetes nodes,
Armada manifests, Helm charts, and any other descriptors that
define the build out of a group of servers enter the Airship via
Shipyard. Secrets, such as passwords and certificates use the
same mechanism.
The designs and secrets are stored in Airship's Deckhand, providing for version history and secure storage among other document-based conveniences. - Actions
- Interaction with the site's control plane is done via invocation of actions in Shipyard. Each action is backed by a workflow implemented as a directed acyclic graph (DAG) that runs using Apache Airflow. Shipyard provides a mechanism to monitor and control the execution of the workflow.
