KBase Relation Engine

This repo holds the code associated with the KBase relation engine, previously held in https://github.com/kbase/relation_engine_api and https://github.com/kbase/relation_engine_spec.

Relation Engine Spec

spec/

The spec/ directory holds the schemas for stored queries, collections, views, analyzers, and migrations for the relation engine graph database service.

These specifications are used by the Relation Engine API.

Relation Engine API

relation_engine_server/

The relation engine server (relation_engine_server/) is a simple API that allows KBase community developers to interact with the Relation Engine graph database. You can run stored queries or do bulk updates on documents.

Relation Engine Startup

  • Docker image is built with environment variable SPEC_RELEASE_PATH=/opt/spec.tar.gz. This contains the specs from the repo itself.
  • Wait for response from auth, workspace, and arangodb services, as they are set up
  • Specs are set up. Either the repo specs or remote specs are loaded into the specs root path
  • Collections, views, and analyzers from the specs are added to the ArangoDB server. If the collection, view, or analyzer already exists, but in a different configuration, it will not be overwritten.
  • Collections, views, and analyzers from the loaded specs are compared to those on the ArangoDB server. If the loaded specs' attributes are not recursively a subset of the server specs, then an exception is raise. (This is just preliminary validation behavior.)

Relation Engine builds

The Relation Engine is available on github packages. These images are built by the configs in the .github repo. The develop tags are located at https://github.com/kbase/relation_engine/pkgs/container/relation_engine-develop
e.g.

docker pull ghcr.io/kbase/relation_engine-develop:latest (Built upon merging a PR)
docker pull ghcr.io/kbase/relation_engine-develop:pr-93 (Built upon creating a PR)

How to Deploy in CI

The CI service is available in the relationapi service

  • Press Upgrade Arrow
  • Ensure the relationapi service uses ghcr.io/kbase/relation_engine-develop:latest
  • Ensure the Always pull image before creating box is ticked
  • Press Upgrade button
  • If the deployment suceeded, you can finish the upgrade. If not, you can press the rollback button.

(For deployments to other environments, request help from the #devops channel)

How to Deploy to production

  • Merge from Develop to Main
  • Draft a release using semantic versioning (e.g 1.2.3) by creating a tag with the target of Main
  • Ensure release notes are updated manually and/or by AutoGenerate Release Notes

Testing

To run tests:

make test
