Spring Boot in a Container

Engineering
Dave Syer

Many people are using containers to wrap their Spring Boot applications, and building containers is not a simple thing to do. This is an article for developers of Spring Boot applications, and containers are not always a good abstraction for developers - they force you to learn about and think about very low level concerns - but you will on occasion be called on to create or use a container, so it pays to understand the building blocks. Here we aim to show you some of the choices you can make if you are faced with the prospect of needing to create your own container.

Hi Spring fans! Welcome to another installment of This Week in Spring. I’m in Tokyo, Japan, for the epic SpringOne Tour Japan event and then, it’s off to Seoul, South Korea and then Singapore. I’m trying to keep busy! I delivered two 3+ hour long talks yesterday despite a blistering fever and today I presented at the SpringOne Tour and then, tonight, I had the honor of presenting at a joint meeting of the JJUG and JSUG here in Tokyo on Tuesday evening (starting about 7h ago).

If you’re about, don’t hesitate to say hi! I’d love to chat about anything and everything Pivotal and Spring with ya! Anyway, we’ve got a ton to get to, so let’s get to it!

I’m pleased to announce the first milestone release of Spring CredHub 2.0.0, available now in the Spring milestone repository.

CredHub

CredHub provides centralized credential management to the Cloud Foundry platform. CredHub implements an HTTP API to securely store, generate, retrieve, and delete credentials of various types.

Spring CredHub provides a Java binding for the CredHub API, making it easy to integrate Spring applications with CredHub.

The 2.0.0 release brings support for CredHub server versions 1.x and 2.x, and the CredHub v1 and v2 APIs. This release also provides compatibility with Spring Framework 5 and Spring Boot 2. The GA release of Spring CredHub 2.0.0 will add a reactive alternative to the existing interfaces.

Project Update: Spring Cloud Data Flow for Apache Mesos and Apache YARN

News and Events
Mark Pollack

Dear Spring community,

The Spring Cloud Data Flow team have been happy stewards of the Spring Cloud Deployer and Spring Cloud Data Flow implementations of Apache Mesos and Apache YARN.

We now feel that TrustedChoice.com will be a better home for Apache Mesos implementation of Spring Cloud Deployer and Spring Cloud Data Flow, and we are donating the projects to them to carry it forward.

The development will now be managed directly by the team (Adam J. Weigold, Phil Egelston, Justin Mathieu, and Cole Anderson) at TrustedChoice.com, as the Spring Cloud Data Flow team will no longer maintain it.
