The Stream Reactor dockers contains a Connect Cluster worker and a connector from the Stream Reactor.
The entrypoint of the docker
Environment variables prefixed with CONNECTOR are used to create a connector properties file. Environment variables beginning with CONNECT are used to create the properties file for the Kafka Connect Cluster. The Connector properties file is then pushed via the Connect CLI to the Connect workers API once it’s up to start the connector.
The expected use case is that the Connect Worker joins with other dockers or Kubernetes pods deployed via Helm to form a Connect Cluster for a specific instance of one connector only.
The Lenses secret provider is bundled into the dockers with the connector.
