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.
For a simple getting-started experience, see the spring-cloud-dataflow-server-local (sibling)
project. The build for that project produces a boot-executable LocalDataFlowServer that relies on
an implementation of the Spring Cloud Deployer SPI that launches each stream app as a new JVM
process on the same host as the LocalDataFlowServer itself. By default the local server is
auto-populated with apps generated from the
spring-cloud-stream-app-starters
project.
