  • Produce metrics (with StatsD)
  • Publish server event to external systems (with Webhooks, AMQP, ...)
  • BDD testing (with Cucumber)

See for planned features.

Under the hood

The project is developed with Node.js and uses the Express Framework.

The backend storage is pluggable. Documents can be stored into MongoDB or Elasticsearch. It's planned to support other storage backends (like CouchBase, Cassandra, ...)

The indexation engine is also pluggable, but only Elasticsearch is supported for now.

Redis is used as an event bus to exchange data between services.



  • Docker
  • [Docker compose][docker-compose]

Run tests

# Start required backends (ElasticSearch, MongoDB, Redis)
# Launch tests
# Teardown backends
make build deploy test undeploy

You can also launch tests using Elasticsearch as main database:

make build deploy with-elastic test undeploy

Start the server

Warning: This is useful for testing or have a development server. If you want to operate the service and don't lost your data please refer below.

# Start required backends (ElasticSearch, MongoDB, Redis) and the API server.
# (Using dev configuration: etc/default/dev.env)
make with-app deploy logs

If you want to start the server with another configuration (for instance: staging) you need to override the env variable of the Makefile:

make with-app deploy env=staging

Configuration files are located into the etc/default directory. See etc/default/dev.env for development configuration details.

Finally you can remove everything like this:

# Stop and destroy all services
make undeploy

Install the server as a service

You need to have all backend services up and running with following Docker names:

  • mongodb
  • elasticSearch
  • redis
# Install systemd configuration (for staging env)
make install env=staging

Un-install is as simple: make uninstall

Started services are:

  • keeper-core-api: Core API server.
  • keeper-core-job-worker: Job worker to process background tasks
  • keeper-data-backup: Backup documents files (scheduler).
