Spring Cloud Data Flow Server Core

The spring-cloud-dataflow-server-core subproject of spring-cloud-dataflow provides a common REST API and UI that can be used to create a Data Flow Server for a particular deployment environment when combined with an implementation of the spring-cloud-deployer SPI for that environment.

The REST API includes a StreamDefinitionController and TaskDefinitionController that manage stream and task definitions by delegating to the StreamDefinitionRepository and TaskDefinitionRepository, respectively. The StreamDeploymentController and TaskDeploymentController delegate to the AppDeployer and TaskLauncher provided by the underlying spring-cloud-deployer SPI implementation. Other controllers provide endpoints for managing the AppRegistry, viewing counters, etc.

The spring-cloud-dataflow-server project uses this dependency and pulls in task platform deployers for CloudFoundry and Kubernetes.
