    • configuration-service provides GET endpoints for project/stage/service and endpoints for resource management.

    • mongodb-datastore provides GET endpoint to retrieve Keptn events.

Architecture Details of Keptn API

Keptn 0.6.2 introduced an NGINX as new K8s deployment and service called api-gateway-ngnix shown in the figure below. This NGINX allows to route the traffic and ensures that all requests are authenticated using the /auth endpoint of the api-service.

  • The api-service now does not implement endpoints of the configuration-service anymore.
  • The configuration-service is exposed to the public. Endpoints that are not intended to be used from the public (e.g., deleting a project) are marked and the description is accordingly adapted.
  • The mongodb-datastore is exposed to the public. Endpoints that are not intended to be used from the public are marked and the description is accordingly adapted.
