Spring Cloud Spinnaker 1.0.0.M3

Greetings Spring community,

I am happy to release the second milestone for Spring Cloud Spinnaker. Spring Cloud Spinnaker bundles up the continuous delivery Spinnaker platform, and provides a 1-click installer to let you install it to any certified Cloud Foundry provider.

UPDATE: This blog post originally cited M2, however one of our early adopters spotted a critical bug, so M3 has been built and released with the fix in hand.

Key features included in this release:

  • Much more simplified way to login, select your org and space from dropdowns, etc., shooting for as simple an experience as possible.

  • Ability to manage two CF spaces

  • Support for Jenkins and Travis CI monitoring.

  • Configure email and slack notifications

  • Move to hosted uber JARs, meaning installing the installer is no longer a bugbear

  • Other enhancements regarding to Spinnaker itself include ability to clone server groups, an upgrade to our Reactor-based cf-java-client 2 library, and also enhance UX showing more CF information than ever.

Dependency Management Plugin 1.0.0.RC1

It’s my pleasure to announce that 1.0.0.RC1 of the Dependency Management Plugin has been released. It’s available from Gradle’s Plugin Portal as well as Maven Central and Bintray.

What’s new?

The plugin’s been rewritten in Java and its API has been formalised. A clear separation between that API and the plugin’s internals has been introduced. This has required a few breaking changes but you are unlikely to be affected if you were using the Groovy DSL.

Converting to Java and formalising the API has also enabled a couple of enhancements:

Reactor Kafka 1.0.0.M1 released

We are pleased to announce the release of the first milestone of Reactor Kafka 1.0.0.

What is Reactor Kafka?

Reactor Kafka is a reactive API for Apache Kafka based on Project Reactor. Reactor Kafka API enables messages to be published to Kafka topics and consumed from Kafka topics using functional APIs with non-blocking back-pressure and very low overheads. This enables applications using Reactor to use Kafka as a message bus or streaming platform and integrate with other systems to provide an end-to-end reactive pipeline.

The value proposition for Reactor Kafka is the efficient utilization of resources in applications with multiple external interactions where Kafka is one of the external systems. End-to-end reactive pipelines benefit from non-blocking back-pressure and efficient use of threads, enabling a large number of concurrent requests to be processed efficiently. The optimizations provided by Project Reactor enable development of reactive applications with very low overheads and predictable capacity planning to deliver low-latency, high-throughput pipelines.

This Week in Spring - December 13th, 2016

Welcome to another installment of This Week in Spring! This year has flown so quickly by! Can you believe we’re less than 19 days until 2017? I’m utterly stunned. I suppose I shouldn’t be, though, given the breakneck speed of progress and new software releases from the Spring team and the community. What a good problem to have!

This week, after returning from Australia early Sunday morning, I hacked with my buddy Josh McKenty, I spoke with my buddy Baruch at the San Francisco Java User Group on Monday, will speak with my buddy Matt Raible at the Denver Java User Group on Wednesday (don’t miss it!), and will speak in Saint Louis on Thursday and Hartford on Friday. It’s going to be a fun week and if you’re around, don’t hesitate to say hi.

SpringOne Platform 2016 Replay: High Performance Microservices with Ratpack and Spring Boot

Recorded at SpringOne Platform 2016.
Speaker: Dan Woods

Ratpack and Spring Boot are a match made in microservice heaven. Each brings its respective strengths to the task of building a compelling service for the cloud. Spring Boot’s incorporation of the Spring and Spring Cloud ecosystems make it an excellent choice for building service components; Ratpack’s nature as a reactive web framework and its emphasis on performance and efficiency make it a premiere choice for a durable web tier. When the two frameworks join forces, developers become unstoppable. This talk will showcase Ratpack and Spring Boot’s complementary integrations, and demonstrate, through live coding, building a high performance microservice.

SpringOne Platform 2016 Replay: No outage database development with Spring Boot and Liquibase

Recorded at SpringOne Platform 2016.
Speakers: Barrington-Hughes, Ramaswamy, Premier Healthcare Inc

Pavi and I work on a project in Premier where we’ve embedded Liquibase into the start of our Spring Boot applications to upgrade our database in-direct coupling with the code we are deploying.

Using a measured and planned approach to agile database development and careful refactoring of the database with more frequent but smaller changes, we facilitate having no outage deployments along with database schema upgrades.

SpringOne Platform 2016 Replay: Next Level Spring Boot Tooling

Recorded at SpringOne Platform 2016.
Speakers: Martin Lippert, Kris De Volder, Andy Clement

The recent releases of the widely used Spring tooling for Eclipse have focused a lot on making Spring Boot app and microservice development easier and more effective. In this talk we will showcase the latest features for working with Spring Boot - using live demos and live coding. We will show the easiest ways to get started with Spring Boot, move on to advanced features for dealing with Spring Boot properties in property and YAML files (including greatly improved content-assist, validations, hover help), and demo the Spring Boot dashboard. This major innovation in the Spring tooling makes it extremely easy to deal with potentially many Spring Boot microservice projects in your workspace. We will demo all the new features, including advanced editing of Cloud Foundry manifest files and the ability to detect and merge configuration changes between your cloud runtime and your workspace projects. The talk is all about being more effective in your IDE when working with Spring Boot and turning your IDE into a microservice development center when working with Spring Boot, Spring Cloud, and a cloud-native runtime like Cloud Foundry.
