Hi Spring fans! Welcome to another installment of This Week in Spring! This week I’m in Stockholm, Sweden, for the epic (and snowy) JFokus event, then it’s off to Frankfurt, Germany for the OOP show. If you’re at either event, don’t hesitate to reach out and say hi on Twitter (@starbuxman)!
- Spring Cloud Skipper 1.0.GA is here! A cross-cloud (Cloud Foundry, Kubernetes) option for continuous delivery/updating/rollback/query of Spring Boot-based applications. Spring Cloud Skipper underpins the recently added support in Spring Cloud Data Flow for versioning and rolling back stream definitions, but it’s also useful in its own right.
- Spring Cloud Stream lead Oleg Zhurakousky just announced Spring Cloud Stream Elmhurst.M4 /2.0.0.M4 Release . The new release includes performance improvements around content-type resolution, Introduction of Polling Source as an alternative to the event-driven message consumption,
StreamListenerinfrastructure enhancements to primarily deal with multiple destination, continuing documentation improvements, various other enhancements and bug fixes, and more.
- Pivotal Web Services (PWS) is Pivotal’s hosted, multi-tenant version of Cloud Foundry. Cloud Foundry is based on BOSH which makes easy, centralized upgrades and deployments of new releases as easy as possible. This post looks at the timeline for deploying a new release of the Ubuntu “stemcell” that underpins all running Linux-based applications on PWS after the Spectrum/Meltdown exploit hit. It took less than an hour of engineer time to update the root image, and about 16 hours to see the entire platform updated with rolling deploys, automatically, after deploying the updated stemcell change. During this time, service was not disrupted for any of the countless applications deployed to the platform.

- Spring Boot lead Phil Webb has just announced Spring Boot 1.5.10. This release includes an important fix for security vulnerability CVE-2018-1196, which can affect anyone using Spring Boot’s systemd and init.d service support. It also provides the latest version of Spring Security which fixed CVE-2018-1199. In addition the security fix, Spring Boot 1.5.10 includes over 55 fixes, improvements and dependency updates.

- It is pretty cool that the free sample of the book that my friend Kenny Bastani and I worked on, Cloud Native Java, was the #1 most popular / downloaded eBook asset from Pivotal in 2017.
- This is a pretty cool example of passwordless authentication with Spring Security. The idea is simple but the code sophisticated: you enter an email or a username, the system emails you, and then you click on the email to be logged in.

Improved actuator JSON structures, helpful security matchers for both Servlet and Reactive deployements, and much more. It also picks up 57 issues that were closed for the recent 1.5.10 release, including an important fix for security vulnerability CVE-2018-1196. This release is huge and it begins the journey towards a final release! Get the bits, kick the tires, NOW!
