Control

This is the external-facing API service to operate on and query Deckhand-managed data.

v1.0 Endpoints

POST /documents

Accepts a multi-document YAML body and creates a new revision which adds those documents. Updates are detected based on exact match to an existing document of schema + metadata.name. Documents are "deleted" by including documents with the tombstone metadata schema, such as:

`yaml --- schema: any-namespace/AnyKind/v1 metadata: schema: metadata/Tombstone/v1 name: name-to-delete ...`

This endpoint is the only way to add, update, and delete documents. This triggers Deckhand's internal schema validations for all documents.

If no changes are detected, a new revision should not be created. This allows services to periodically re-register their schemas without creating unnecessary revisions.

Sample response:

`yaml --- created_at: '2017-07-31T14:46:46.119853' data: path: to: merge: into: ignored: {data: here} parent: {foo: bar} substitution: {target: null} deleted: false deleted_at: null id: f99630d9-a89c-4aad-9aaa-7c44462047c1 metadata: labels: {genesis: enabled, master: enabled} layeringDefinition: abstract: false actions: - {method: merge, path: .path.to.merge.into.parent} - {method: delete, path: .path.to.delete} layer: region parentSelector: {required_key_a: required_label_a, required_key_b: required_label_b} name: unique-name-given-schema schema: metadata/Document/v1 storagePolicy: cleartext substitutions: - dest: {path: .substitution.target} src: {name: name-of-source-document, path: .source.path, schema: another-service/SourceType/v1} name: unique-name-given-schema revision_id: 0206088a-c9e9-48e1-8725-c9bdac15d6b7 schema: some-service/ResourceType/v1 updated_at: '2017-07-31T14:46:46.119858'`

GET /revisions

Lists existing revisions and reports basic details including a summary of validation status for each deckhand/ValidationPolicy that is part of that revision.

Sample response:

`yaml --- count: 7 next: https://deckhand/api/v1.0/revisions?limit=2&offset=2 prev: null results: - id: 0 url: https://deckhand/api/v1.0/revisions/0 createdAt: 2017-07-14T21:23Z validationPolicies: site-deploy-validation: status: failed - id: 1 url: https://deckhand/api/v1.0/revisions/1 createdAt: 2017-07-16T01:15Z validationPolicies: site-deploy-validation: status: succeeded ...`

GET /revisions/{revision_id}/documents

Returns a multi-document YAML response containing all the documents matching the filters specified via query string parameters. Returned documents will be as originally posted with no substitutions or layering applied.

Supported query string parameters:

• schema - string, optional - The top-level schema field to select. This may be partially specified by section, e.g., schema=promenade would select all kind and version schemas owned by promenade, or schema=promenade/Node which would select all versions of promenade/Node documents. One may not partially specify the namespace or kind, so schema=promenade/No would not select promenade/Node/v1 documents, and schema=prom would not select promenade documents.
• metadata.name - string, optional
• metadata.layeringDefinition.abstract - string, optional - Valid values are the "true" and "false".
• metadata.layeringDefinition.layer - string, optional - Only return documents from the specified layer.
• metadata.label - string, optional, repeatable - Uses the format metadata.label=key=value. Repeating this parameter indicates all requested labels must apply (AND not OR).

Sample response:

`yaml created_at: '2017-07-31T14:36:00.352701' data: {foo: bar} deleted: false deleted_at: null id: ffba233a-326b-4eed-9b21-079ebd2a53f0 metadata: labels: {genesis: enabled, master: enabled} layeringDefinition: abstract: false actions: - {method: merge, path: .path.to.merge.into.parent} - {method: delete, path: .path.to.delete} layer: region parentSelector: {required_key_a: required_label_a, required_key_b: required_label_b} name: foo-name-given-schema schema: metadata/Document/v1 storagePolicy: cleartext substitutions: - dest: {path: .substitution.target} src: {name: name-of-source-document, path: .source.path, schema: another-service/SourceType/v1} name: foo-name-given-schema revision_id: d3428d6a-d8c4-4a5b-8006-aba974cc36a2 schema: some-service/ResourceType/v1 updated_at: '2017-07-31T14:36:00.352705'`

Testing

Document creation can be tested locally using (from root deckhand directory):

$ curl -i -X POST localhost:9000/api/v1.0/documents \
     -H "Content-Type: application/x-yaml" \
     --data-binary "@deckhand/tests/unit/resources/sample_document.yaml"

# revision_id copy/pasted from previous response.
$ curl -i -X GET localhost:9000/api/v1.0/revisions/0e99c8b9-bab4-4fc7-8405-7dbd22c33a30/documents
