kubernetes-client VS Quarkus

While that is true I‘d like to suggest taking a look at this client: https://github.com/fabric8io/kubernetes-client

I am trying to program the patching/rolling upgrade of k8s apps by taking deployment snippets as input. I use patch() method to apply the snippet onto an existing deployment as part of rollingupdate using fabric8io's k8s client APIS.. Fabric8.io kubernetes-client version 4.10.1I'm also using some loadYaml helper methods from kubernetes-api 3.0.12.

This approach works fine on our DIND-Kubernetes environment. However, when tried to port the deployment onto a Docker-EE Kubernetes environment we ran into trouble because the command kubectl label pod generates a run time error which is completely misleading (also see https://github.com/fabric8io/kubernetes-client/issues/853).

To be specific, I am trying to use https://github.com/fabric8io/kubernetes-client/tree/master/crd-generator in scala code. If it is only duplicating one class or so, that seems manageable. But if I need to rewrite everything I am less confident

In terms of spinning up and managing everything, like, the stuff that's not Java apps. But some of the old fabric8 work - the predecessor to jKube - provides Java APIs and utilities to doing things like writing kubernetes operators in Java. Check out the kubernetes-client project. A lot of people never even learn about kubernetes operators, and just think "I have a service, la la la" plug their ears and then assume there will be some magic operational team that will deploy some service mesh app to solve all their problems.

Fabric8 is a very good Solution. I played also with k8s provided solution but especially custom resource definitions are a hell. I can recommend fabric8 it’s also used in operators like strimzi https://github.com/fabric8io/kubernetes-client

As the name says, this article is all about how to Cancel TaskRuns in Tekton using the Fabric8 Tekton client. You can see the latest example code here

Can the service account token, be used programmtically e.g., using https://github.com/fabric8io/kubernetes-client ?

Meanwhile, if you're building something smaller than Netflix, I'm writing a book just for that (https://opinionatedlaunch.com/).

It's about mobile apps, but I talk about backend at great length, especially since my background is Java. The book is called "opinionated" because I cover Quarkus (https://quarkus.io/), monolith, Fly.io, and no K8s.

Quarkus is a Java based framework tailored for GraalVM and HotSpot, which results in an amazingly fast boot time while having an incredibly low memory footprint. It offers near instant scale up and high density memory utilization which can be very useful for container orchestration platforms like Kubernetes or Serverless runtimes like AWS Lambda.

Other useful articles related to Quarkus extension development can be found under the Writing Extensions guide category on the Quarkus.io website.

Quarkus is one of Java frameworks for microservices development and cloud-native deployment. It is developed as container-first stack and working with GraalVM and HotSpot virtual machines (VM).

If you GraalVM Native Image or one of the frameworks based on it then bootstrap cost disappears:

We are open to practice using any open-source project, however, we want to set a sharp focus on projects maintained by the Red Hat, and our own projects in the Caravana Cloud organization on github. If there is no reason to do differently, we'll build using technologies such as OpenShift, Quarkus, Ansible and related projects.

The Quarkus you are talking about is this one? https://quarkus.io/
