This Maven plugin is a one-stop-shop for building and deploying Java applications for Docker, Kubernetes and OpenShift. It brings your Java applications on to Kubernetes and OpenShift. It provides a tight integration into maven and benefits from the build configuration already provided. It focuses on three tasks:
- Building Docker images
- Creating OpenShift and Kubernetes resources
- Deploy application on Kubernetes and OpenShift
To enable fabric8 maven plugin on your project just add this to the plugins sections of your pom.xml:
<plugin>
<groupId>io.fabric8</groupId>
<artifactId>fabric8-maven-plugin</artifactId>
<version>${fmp.version}</version>
</plugin>
Now in order to use fabric8 maven plugin to build or deploy, make sure you have an OpenShift/Kubernetes cluster up and running. After making sure of that, you can simply run your app in the cluster :
mvn fabric8:deploy
After you issue this command would start building resources and then deploy them to the running cluster. Below is a snippet of the build log on running spring-boot project in samples/spring-boot directory on MiniKube :

Want to get started fast? Check out the busy Java developers guide to developing microservices on Kubernetes and Docker.
The full documentation can be found in the User Manual [PDF]. It supports the following goals:
| Goal | Description |
|---|---|
fabric8:resource |
Create Kubernetes and OpenShift resource descriptors |
fabric8:build |
Build Docker images |
fabric8:push |
Push Docker images to a registry |
fabric8:deploy |
Deploy Kubernetes / OpenShift resource objects to a cluster |
fabric8:watch |
Watch for doing rebuilds and restarts |
- Includes docker-maven-plugin for dealing with Docker images and hence inherits its flexible and powerful configuration.
- Supports both Kubernetes and OpenShift descriptors
- OpenShift Docker builds with a binary source (as an alternative to a direct image build agains a Docker daemon)
- Various configuration styles:
- Zero Configuration for a quick ramp-up where opinionated defaults will be pre-selected.
- Inline Configuration within the plugin configuration in an XML syntax.
- External Configuration templates of the real deployment descriptors which are enriched by the plugin.
- Docker Compose Configuration provide Docker Compose file and bring up docker compose deployments on a Kubernetes/OpenShift cluster.
- Flexible customization:
- Generators analyze the Maven build and generated automatic Docker image configurations for certain systems (spring-boot, plain java, karaf ...)
- Enrichers extend the Kubernetes / OpenShift resource descriptors by extra information like SCM labels and can add default objects like Services.
- Generators and Enrichers can be individually configured and combined into profiles

- Examples are in the samples directory
- Many fabric8 Quickstarts use this plugin and are good showcases, too.
- You'll find us in the fabric8 community and on IRC freenode in channel #fabric8 and we are happy to answer any questions.
- Contributions are highly appreciated and encouraged. Please send us Pull Requests.
This is a complete rewrite of the former fabric8-maven plugin. It does not share the same configuration syntax, but migration should be straight forward - please use the fabric8:migrate goal from 2.x of the plugin.
