Event Bus

Overview

The Event Bus enables Kyma to integrate with various other external solutions. The integration uses the publish-subscribe messaging pattern that allows Kyma to receive business Events from different solutions, enrich the events, and trigger business flows using lambdas or services defined in Kyma. See the Event Bus documentation.

Docker Images

Currently, Event Bus makes the following three Docker images available to the event-bus Helm chart:

• event-publish-service
• subscription-controller
• nats-streaming-init

There is also end-to-end test Docker image which is used in TestDefinition executed by Octopus.

Development

The two binaries of Event Bus reside under cmd/event-bus-XXXX "e.g. cmd/event-publish-service". They each have a Makefile to build and test the component as well as to create and push a Docker image. The following table explains the various make targets.

Command	Description
make	This is the default target for building the Docker image. It tests, compiles, creates, and appropriately tags a Docker image.
make build	Runs all the tests and the linter. It compiles the binary in the bin directory.
make push-image	Pushes the Docker image to the registry specified in the REGISTRY variable of the Makefile.
make build-image	Creates a Docker image.
make test	Run all the tests.
