This patchset fixes a bug where Deckhand was failing to perform substitution and layering on document sets where all the documents had a storagePolicy of encrypted. Deckhand would attempt to substitute from an encrypted source document, but when that document marked as encrypted, it fails because the source doc had been redacted. The behavior now goes as follows: - Resolve Barbican references before layering and substitution have been performed so that the prior two operations don't attempt to operate on a Barbican reference - After substitution, redact the destination document if it is marked as encrypted - Now, after substition, we can redact the rest of the documents and substitutions Change-Id: I725775d554c9eed2692fc6203c416a7119646680
Deckhand
Deckhand provides document revision management, storage and mutation functionality upon which the rest of the Airship components rely for orchestration of infrastructure provisioning. Deckhand understands declarative YAML documents that define, end-to-end, the configuration of sites: from the hardware -- encompassing network topology and hardware and host profile information -- up to the software level that comprises the overcloud.

Core Responsibilities
- layering - helps reduce duplication in configuration by applying the notion of inheritance to documents
- substitution - provides separation between secret data and other configuration data for security purposes and reduces data duplication by allowing common data to be defined once and substituted elsewhere dynamically
- revision history - maintains well-defined collections of documents within immutable revisions that are meant to operate together, while providing the ability to rollback to previous revisions
- validation - allows services to implement and register different kinds of validations and report errors
- secret management - leverages existing OpenStack APIs -- namely Barbican -- to reliably and securely store sensitive data
Getting Started

Integration Points
Deckhand has the following integration points:
- Barbican (OpenStack Key Manager) provides secure storage for sensitive data.
- Keystone (OpenStack Identity service) provides authentication and support for role based authorization.
- PostgreSQL is used to persist information to correlate workflows with users and history of workflow commands.
Note
Currently, other database back-ends are not supported.
Though, being a low-level service, has many other Airship services that integrate with it, including:
