I will accept, I am a massive lover away from ability twigs and you will proud of they. I understand the my acquaintances are likely to bring me personally heck for that (thinking about your Thomas Traude ). A short while after I obtained a notification one my personal Jenkins build is red-colored.

Looks like we have some flaky tests. Depending on the environment, the application context may fail to load. This is the very definition of frustrating, but don't worry, I enjoy these kinds of challenges.
In case you're asking yourself why the tests fail if the builds run in Kubernetes, that's because they don't. Our Jenkins jobs don't run in Kubernetes, since we make extensive use of Testcontainers . If you don't use them, be sure to check them out, awesome. And their new cloud solution looks very promising.
Disabling Spring Cloud Kubernetes into the tests
Spring Cloud Kubernetes can be disabled in tests using the property .kubernetes.enabled . Drop that property into your tests like so, and you're good to go (or at least it used to work).
1( "test" ) 2(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_Vent, 3 properties ="spring season.affect.kubernetes.enabled=false" >) 4 class ApplicationIT < 5 >
I didn't understand the issue at first, it should have been disabled. We've been using the new Kubernetes Java Client successfully in other projects, and there the tests aren't flaky. I took another look, turns out that our projects are using different versions. Version 2020.0.1 works as expected.
A change introducing additional configuration properties in the Kubernetes Java Client had an mujeres buscando marido unintentional side-effect; the property .kubernetes.enabled no longer works as expected. There is no longer a single property to disable Spring Cloud Kubernetes.
Issues have been reported here and here , with the fixes scheduled for 2020.0.5 . Unfortunately, as of writing this article, version 2020.0.5 hasn't been released. This enhancement was included in Spring Cloud 2020.0.2 , which explains why the version 2020.0.1 worked in other projects.
Second take to – with the existing fabric8 client

Locally the build is green. Push to Jenkins, and wait. Crossing my fingers always helps, so that's what I did. And what do you know, worked like a charm; no issues, nothing, zero, zip. I love when things just work.
I should have known better. The fabric8 client has been serving us well for many years. Don't mess with a running system!
Coaching learned upgrading Spring season Cloud Kubernetes
It would appear the Spring Cloud Kubernetes Java Client is not yet ready. The Kubernetes Java Client introduced their own Spring integration which doesn't integrate with the Spring configuration properly. Hopefully the two projects are cooperating, and we'll get a nice clean Spring-based configuration in the future. Once version 2020.0.5 is released, I'll give it another try.
