Spring Cloud Data Flow Chart


NOTE: This chart has been DEPRECATED. Please use stable/spring-cloud-data-flow.


Spring Cloud Data Flow is a toolkit for building data integration and real-time data processing pipelines.

Pipelines consist of Spring Boot apps, built using the Spring Cloud Stream or Spring Cloud Task microservice frameworks. This makes Spring Cloud Data Flow suitable for a range of data processing use cases, from import/export to event streaming and predictive analytics.

Chart Details

This chart will provision a fully functional and fully featured Spring Cloud Data Flow installation that can deploy and manage data processing pipelines in the cluster that it is deployed to.

MySQL and Redis are used as the stores for Spring Cloud Data Flow state and RabbitMQ is used for the pipelines' messaging layer.

For more information on Spring Cloud Data Flow and its capabilities, see it's documentation.

Prerequisites

Assumes that serviceAccount credentials are available so the deployed Data Flow server can access the API server (Works on GKE and Minikube by default). See Configure Service Accounts for Pods

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release incubator/spring-cloud-data-flow

If you are using a cluster that does not have a load balancer (like Minikube) then you can install using a NodePort:

$ helm install --name my-release --set server.service.type=NodePort incubator/spring-cloud-data-flow

Note that this chart pulls in many different Docker images so can take a while to fully install.
