• Select one of the two API collections:

  • api-service contains endpoints to authenticate, get Keptn metadata, create/delete a project, to create service, and to send/get events.

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

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

  

• Clicking on an endpoint reveals more details how to use it, including definitions and examples of the payload.

  

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.
