Spring Cloud Data Flow 1.3.0.M1 released

On behalf of the team, I am pleased to announce the first milestone release of Spring Cloud Data Flow 1.3.0.

Local Server: Getting Started Guide.

Usability is one of the big focus for our team and in the 1.3 release-line, we are aiming to modernize the dashboard with an upgraded client-side technology stack, improved tooling, and documentation. The focus is to improve the readability, user-experience, and the overall performance.

Spring Cloud Data Flow 1.2.1 released

On behalf of the Spring Cloud Data Flow team, I’m pleased to announce the release of Spring Cloud Data Flow and Spring Cloud Data Flow for Cloud Foundry 1.2.1.RELEASE. This release provides several improvements around OAuth2 authorization.

Here are the relevant links to documentation and getting started guides.

Spring Cloud Data Flow now provides role support for OAuth2, converging with the VIEW, CREATE, MANAGE roles that Data Flow supports when using the traditional security option. Considering the varying use-case requirements across organizations in regards to security roles, the out-of-the-box implementation will assign all the VIEW, CREATE, MANAGE roles to the OAuth authenticated user. However, this can be customized by providing your own AuthoritiesExtractor.

Community-Driven Spring Integration Extensions

The Spring Integration team proudly announces the availability of the Spring Integration Extensions repository. The main goal for this new GitHub-based repository is to promote a vibrant community of adapter and extension developers, and to encourage a broader segment of the community to contribute to the project. The Spring Integration Extensions project is hosted at:

This new repository will give us the flexibility to incorporate new contributions much more rapidly, without having to go through the core Spring Integration framework’s stricter vetting process. Since each community contributed extension is a separate project in the Spring Integration Extensions repository, it will have its own release life-cycle independent from the one that governs the core Spring Integration framework. As a result, this will allow for more frequent releases.

Rapid Cloud Foundry Deployments with Maven

Apache Maven is a very popular choice in the Java community for building and deploying applications.  The Cloud Foundry team has released the Cloud Foundry Maven Plugin to integrate with applications’ development lifecycle, including deployment to the cloud.  The same Maven plugin can be used to manage application pushes and updates to any Cloud Foundry instance.

One of Cloud Foundry’s main promises is to make your life as a developer a whole lot easier without limiting available choices. Cloud Foundry not only supports a plethora of languages (Java, Groovy, Scala, Ruby etc.) and frameworks (Spring, Grails, Rails, Sinatra, Lift etc.) but it also allows you to deploy your applications to different environments. This includes public clouds, such as Cloudfoundry.com and AppFog.compartner-provided cloud offerings, single VM Micro Cloud Foundry, and your own private cloud using Cloud Foundry open source, which is available to everyone under a very liberal Apache License v2.
