## Introduction
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.
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
org.eclipse.jkube
kubernetes-maven-plugin
${jkube.version}
```
- Run the JKube commands, for instance:
```shell
mvn package k8s:build k8s:push k8s:resource k8s:apply
```

### 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
```

### 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
```

### 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

## 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 8080:32353/TCP 58m
kubernetes ClusterIP 10.96.0.1 443/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. For more information about history, please see [REBRANDING.md](./REBRANDING.md)
