Use YAML formatting for built-in Deckhand schemas
used for validations to align with other UCP services.
The second most important intention behind this PS
is to allow pre_validate flag to cascade correctly
between the layering and document_validation modules.
If pre_validate is true, then:
* the base_schema validates ALL documents
* ALL built-in schemas validate the appropriate
document given a schema match
* NO externally registered DataSchema documents
are used for validation
Else (if pre_validate is false):
* the base_schema validates ALL documents
* ALL built-in schemas validate the appropriate
document given a schema match
* ALL externally registered DataSchema documents
are used for validation given a schema match
A more minor change is setting pre_validate flags in
all modules to True for consistency. The idea is to
facilitate the way other projects that import Deckhand
in directly interface with Deckhand.

Deckhand
Deckhand is a storage service for YAML-based configuration documents, which are managed through version control and automatically validated. Deckhand provides users with a variety of different document types that describe complex configurations using the features listed below.
Core Responsibilities
- layering - helps reduce duplication in configuration while maintaining auditability across many sites
- substitution - provides separation between secret data and other configuration data, while allowing a simple interface for clients
- revision history - improves auditability and enables services to provide functional validation of a well-defined collection of documents that are meant to operate together
- validation - allows services to implement and register different kinds of validations and report errors
Getting Started
For more detailed installation and setup information, please refer to the Getting Started guide.
Testing
Automated Testing
To run unit tests using sqlite, execute:
$ tox -epy27
$ tox -epy35against a py27- or py35-backed environment, respectively. To run individual unit tests, run:
$ tox -e py27 -- deckhand.tests.unit.db.test_revisionsfor example.
To run functional tests:
$ tox -e functionalYou can also run a subset of tests via a regex:
$ tox -e functional -- gabbi.suitemaker.test_gabbi_document-crud-success-multi-bucketIntgration Points
Deckhand has the following integration points:
- 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 backends are not supported.
Though, being a low-level service, has many other UCP services that integrate with it, including:
