Hi Spring fans! Welcome to another installment of This Week in Spring! I've just flown from Singapore and arrived in Hong Kong where I'll be meeting with some of our bigger customers here for a few days. Then, it's off to Taipei where, among other things, I'll be presenting at the Taipei JUG and talking to some customers. If you're in any of these places, don't hesitate to reach out and say hi (@starbuxman)!

With that, we've got a ton to get to so let's get to it!

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.

We will assume that you know how to create and build a basic Spring Boot application. If you don’t, go to one of the Getting Started Guides, for example the one on building a REST Service. Copy the code from there and practise with some of the ideas below. There is also a Getting Started Guide on Docker…

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.

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.

I’m pleased to announce on behalf of the community Spring Security OAuth2 Boot Auto-config 2.0.6 and 2.1.0.

Both releases primarily deliver bug fixes and dependency version updates along with some minor improvements. Of particular note is that these align with recent releases of Spring Boot.

Note that for 2.1.0, gaps in configuration of keys between Resource Server and Authorization Server were brought into parity. Now, it’s possible on the Authorization Server side to configure a single key:

security:
  oauth2:
    authorization:
      jwt:
        key-value: ${PRIVATE_KEY}
