YMNNALFT: Easy Docker Image Creation with the Spring Boot Maven Plugin and Buildpacks

Engineering | Josh Long | January 04, 2021 | ...

Welcome to another installment of You May Not Need Another Library For That (#YMNNALFT)! I've spent a lot of time since 2016 illuminating (or trying to, anyway!) some of the more enormous opportunities in the Spring ecosystem in my Spring Tips videos. Today, however, I come to you in a different spirit, wanting to focus on the little, sometimes hidden, gems that do fantastic things and that might spare you an additional third-party dependency and its implied complexity.

Have you tried out Paketo? It's neat-o! It alleviates one of the biggest pains of cloudy software these days:Dockerfiles.

As an aside: the biggest pain point is, of course, YAML. YAML is why people leave IT! YAML: when you want the indentation-sensitive treachery of Python, with the nonexistent design-time validation of Python and none

This Year in Spring - 2020 Edition

Engineering | Josh Long | December 30, 2020 | ...

Hi, Spring fans!

You know what I did? I goofed, people. I accidentally released This Week in Spring on this the last week of December, the last month of the year! And I shouldn't have. I should not have done that. Usually, you see, I turn the final installment of This Week in Spring for a given year into the aptly named This Year in Spring, a celebration of the big tentpole themes that have defined the year (well, from my perspective, anyway). Then I include the usual This Week in Spring roundup inline. I forgot to do that first part, so I am publishing this as a separate post. Hey, it's tradition

This Week in Spring - December 29th, 2020

Engineering | Josh Long | December 29, 2020 | ...

Hi, Spring fans! Welcome to another installment of This Week in Spring!

How are you? How're things? I spent this morning on a fun two-hour panel hosted by the Barcelona JUG (who run the JBCN conference, among other things) talking about all sorts of things including GraalVM native images, new features in the Java language, cloud-native applications, and so much more. Thanks for having me!

I am so happy about this week's roundup and we've got a lot to cover so let's get to it!

Cloud Events and Spring - part 2

Engineering | Oleg Zhurakousky | December 23, 2020 | ...


We begin with a quick summary of the previous post.

  • Message is an adequate structure and abstraction with which to consume data that represents a Cloud Event in the context of Spring. We hope it was clear.
  • In Spring, our commitment to isolate functional versus non-functional concerns lets us address non-functional aspects (such as send, receive, retry, connect, convert, and others) at the framework level, letting you (mostly) concentrate on actual business logic and letting you keep your code simple and pluggable to a variety of execution contexts (more on this later).


This Week in Spring - December 22nd, 2020

Engineering | Josh Long | December 22, 2020 | ...

Hi, Spring fans! Welcome to another installment of This Week in Spring!

It's December 22nd, 2020, as I write this and I can not believe we're smack dab in the middle of the week and only have two shopping days until Christmas! I don't know if it's just that time of year and I'm flush with the normal amount of warm-n-fuzzies or if it's just that, after a year like 2020, I'm very keen on savoring this precious reprieve. Either way, couldn't be happier. I've got a cold! I'm sick and sneezing and my nose is running, but at least it's not COVID-19, and at least I've got my family and my job, and - all things considered - I feel very, very, veery

Announcing Spring Cloud Stream Applications 2020.0.0 GA Release

Engineering | Soby Chacko | December 21, 2020 | ...

We are glad to announce the GA release of the newly redesigned Spring Cloud Stream applications - 2020.0.0.

We would like to use this release announcement as an opportunity to wrap up the blog series that we started in the summer. Therefore, consider this as part 15 of the blog series. In this blog, we are going to give a rundown of all the previous episodes in the series, but first, let us go through some release details.

Release Overview

2020.0.0 GA release contains the completely revamped functional foundation for the event-streaming applications. The old structure was based on an app starter model in which the critical logic for the applications is provided as part of a starter module. The starters then form the foundation for the applications. While it worked for the previous four generations of these app starters (Avogadro, Bacon, Celsius, Darwin, and Einstein), it deemed necessary to rewrite these starters as reusable functions so that they can be used for a wide array of use cases beyond what is required in the out of the box applications. Therefore, many of the old app starters were refactored and redesigned as functions, suppliers, and consumers. For the out of the box Spring Cloud Stream binder based applications, we take these functional components and use them as the base to build them. Other custom applications, even non-streaming use cases, can be designed using these functional components as a foundation. The functions can…

This Week in Spring - December 15th, 2020

Engineering | Josh Long | December 16, 2020 | ...

Hi, Spring fans! Welcome to another installment of This Week in Spring! Can you believe it's already December 15th? Me either! Another few weeks and this soul annhilating year will be over with and we'll be staring down 2021 filled with new hopes and possibilities! How are you? (Have you dipped into the eggnog yet?) I'm doing alright, thanks! I've been busy, as usual.

Most of that was fun stuff. But, some of that, I confess, was a mess of my own making. I spent Monday cleaning up a fire I'd set for myself. You see, I got a little sloppy with last week's podcast episode. Last week, I was…
