The Core domain module includes the concept of a stream that is a composition of spring-cloud-stream modules in a linear pipeline from a source to a sink, optionally including processor module(s) in between. The domain also includes the concept of a task, which may be any process that does not run indefinitely, including Spring Batch jobs.
The Module Registry maintains the set of available modules, and their mappings to Maven coordinates.
The Module Deployer SPI provides the abstraction layer for deploying the modules of a given stream across a variety of runtime environments. Current SPI implementations support Local deployment, YARN, Cloud Foundry, Mesos and Kubernetes.
The Data Flow Server is a Spring Boot application that provides a common REST API, UI, and an implementation of the module deployer SPI interface for the runtime environment. For each runtime environment there is a different version of the Data Flow server. The github locations for these Data Flow servers are:
The Shell connects to the Admin’s REST API and supports a DSL that simplifies the process of defining a stream and managing its lifecycle.
Instructions to run the Admin Server for each runtime environments can be found in their respective github repositories.

If you are running behind a proxy, then you need to specify the proxy settings via environment properties like this: (choose the ones that are appropriate for your settings)
export MAVEN_LOCAL_REPOSITORY=mylocalMavenRepo
export MAVEN_REMOTE_REPOSITORIES=repo1,repo2
export MAVEN_OFFLINE=true
export MAVEN_PROXY_PROTOCOL=https
export MAVEN_PROXY_HOST=host1
export MAVEN_PROXY_PORT=8090
export MAVEN_PROXY_NON_PROXY_HOSTS='host2|host3'
export MAVEN_PROXY_AUTH_USERNAME=user1
export MAVEN_PROXY_AUTH_PASSWORD=passwdFor more information on building, see this link.
