Fabric8 Java Client for Kubernetes

• Fabric8 has been available as a Java client for Kubernetes since 2015, and today is one of the most popular client libraries for Kubernetes (the most popular is client-go, which is the client library for the Go programming language on Kubernetes). In recent years, fabric8 has evolved from a Java client for the Kubernetes REST API to a full-fledged alternative to the kubectl command-line tool for Java-based development.

• developers.redhat.com: How the fabric8 Maven plug-in deploys Java applications to OpenShift
• Fabric8.io Microservices Development Platform It is an open source microservices platform based on Docker, Kubernetes and Jenkins. It is built by the Red Hat guys.The purpose of the project is to make it easy to create microservices, build, test and deploy them via Continuous Delivery pipelines then run and manage them with Continuous Improvement and ChatOps. Fabric8 installs and configures the following things for you automatically: Jenkins, Gogs, Fabric8 registry, Nexus, SonarQube.

CDK8s

• cdk8s Define Kubernetes native apps and abstractions using object-oriented programming
• blog.twstewart.me: cdk8s-python - A Love and Hate Experience CDK8S is an alpha level library that allows you to write high level abstractions of Kubernetes objects like deployments, services, and more all in your favorite language ( TypeScript, Python, and others).
• qdnqn.com: Kubernetes objects from Go to YAML using Cdk8s Cdk8s is an open-source software development framework for defining Kubernetes applications and reusable abstractions using familiar programming languages and rich object-oriented APIs. cdk8s apps synthesize into standard Kubernetes manifests which can be applied to any Kubernetes cluster.

Eclipse Jkube Java Client for Kubernetes (formerly known as Fabric8). Kubernetes & OpenShift Maven Plugins

• Eclipse JKube 🌟 Cloud-Native Java Applications without a hassle. Eclipse JKube is a collection of plugins and libraries that are used for building container images using Docker, JIB or S2I build strategies. Eclipse JKube generates and deploys Kubernetes/OpenShift manifests at compile time too. It brings your Java applications on to Kubernetes and OpenShift by leveraging the tasks required to make your application cloud-native. Eclipse JKube also provides a set of tools such as watch, debug, log, etc. to improve your developer experience.

Java Operator SDK

• javaoperatorsdk.io: Build Kubernetes Operators in Java without hassle Whether you want to build applications that operate themselves or provision infrastructure from Java code, Kubernetes Operators are the way to go. This SDK will make it easy for Java developers to embrace this new way of automation. The java-operator-sdk is based on the fabric8 Kubernetes client.
