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. This project contains various building blocks for the Kubernetes Java developer toolbox. ### Kubernetes Maven Plugin - [](https://search.maven.org/search?q=g:%22org.eclipse.jkube%22%20AND%20a:%22kubernetes-maven-plugin%22) - [](https://www.eclipse.dev/jkube/docs/kubernetes-maven-plugin) - Add to project: ```xml <plugin> <groupId>org.eclipse.jkube</groupId> <artifactId>kubernetes-maven-plugin</artifactId> <version>${jkube.version}</version> </plugin> ``` - Run the JKube commands, for instance: ```shell mvn package k8s:build k8s:push k8s:resource k8s:apply ``` - :tv: Watch 2-minute demo on YouTube: [](https://youtu.be/FHz5q8ERtPk) ### Kubernetes Gradle Plugin - [](https://search.maven.org/search?q=g:%22org.eclipse.jkube.kubernetes%22%20AND%20a:%22org.eclipse.jkube.kubernetes.gradle.plugin%22) - [](https://www.eclipse.dev/jkube/docs/kubernetes-gradle-plugin/) - Add to project: ```groovy plugins { id "org.eclipse.jkube.kubernetes" version "${jKubeVersion}" } ``` - Run the JKube commands, for instance: ```shell gradle build k8sBuild k8sPush k8sResource k8sApply ``` - :tv: Watch 2-minute demo on YouTube: [](https://youtu.be/TUYl2Vw8bnQ) ### OpenShift Gradle Plugin - [](https://search.maven.org/search?q=g:%22org.eclipse.jkube.openshift%22%20AND%20a:%22org.eclipse.jkube.openshift.gradle.plugin%22) - [](https://www.eclipse.dev/jkube/docs/openshift-gradle-plugin/) - Add to project: ```groovy plugins { id "org.eclipse.jkube.openshift" version "${jKubeVersion}" } ``` - Run the JKube commands, for instance: ```shell gradle build ocBuild ocResource ocApply ``` - :tv: Watch 2-minute demo on YouTube: [](https://youtu.be/uMxEzLdqcik) ### OpenShift Maven Plugin - [](https://search.maven.org/search?q=g:%22org.eclipse.jkube%22%20AND%20a:%22openshift-maven-plugin%22) - [](https://www.eclipse.dev/jkube/docs/openshift-maven-plugin) - Add to project: ```xml <plugin> <groupId>org.eclipse.jkube</groupId> <artifactId>openshift-maven-plugin</artifactId> <version>${jkube.version}</version> </plugin> ``` - Run the JKube commands, for instance: ```shell mvn package oc:build oc:resource oc:apply ``` - :tv: Watch 2-minute demo on YouTube: [](https://youtu.be/ZJzfD-bDxpc) ## Getting started You can take a look at our quickstarts in [quickstarts](./quickstarts) directory that contain sample maven and gradle projects using the latest version of jkube plugin. ### Hello World using Eclipse JKube - Clone repository and move to quickstart [helloworld](https://github.com/eclipse-jkube/jkube/tree/master/quickstarts/maven/hello-world) sample, build project and run JKube goals: ```shell script # 1. Clone repository $ git clone [email protected]:eclipse/jkube.git # 2. Move to Hello World Quickstart folder $ cd jkube/quickstarts/maven/hello-world # 3. Configure your local environment to re-use the Docker daemon inside the Minikube instance. ~ jkube/quickstarts/maven/hello-world : $ eval $(minikube -p minikube docker-env) # 4. Build Project and run JKube goals $ mvn clean install \ k8s:build `# Build Docker Image` \ k8s:resource `# Generate Kubernetes Manifests` \ k8s:apply `# Apply generated Kubernetes Manifests onto Kubernetes` ``` - Check created pod logs: ```shell script # Using Kubectl $ kubectl get pods NAME READY STATUS RESTARTS AGE helloworld-664bf5fdff-2bmrt 1/1 Running 0 9s $ kubectl get svc helloworld NodePort 10.110.92.145 <none> 8080:32353/TCP 58m kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 7h $ curl `minikube ip`:32353/hello Hello World ``` #### Troubleshooting If you experience problems using minikube that pod's status shows 'ImagePullBackOff' and not 'Running' you must share the minikube's docker daemon environment with your shell with: ```shell script $ eval $(minikube -p minikube docker-env) ``` You can remove this from your shell again with: ```shell script $ eval $(minikube docker-env -u) ``` If you don't want to type the command for every new terminal you open, you can add the command to your `.bash_profile` on mac or `.zshrc`. ## Rebranding Notice :loudspeaker: This project is not an effort from scratch. It was earlier called [Fabric8 Maven Plugin](https://github.com/fabric8io/fabric8-maven-plugin). It is just refactored and rebranded version of the project targeted towards Java developers who are working on top of Kubernetes.
