I shall recognize, I am a large partner regarding element branches and you can happy with they. I know a few of my colleagues will likely provide myself hell for the (looking at your Thomas Traude ). A short while after I received an alerts you to definitely my Jenkins generate are 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 Springtime Cloud Kubernetes into the assessment

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_Port, 3 properties ="spring.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 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.

2nd decide to try – by using the present fabric8 client

1  dependency > 2  groupId > org.springframework.affectgroupId > 3  artifactId > spring-cloud-starter-kubernetes-fabric8-configartifactId > 4dependency > 

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!

Classes learned upgrading Springtime 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.
