openshift-maven-plugin

Introduction

This Maven plugin is a one-stop-shop for building and deploying Java applications for OpenShift. It brings your Java applications on to OpenShift. It provides a tight integration into maven and benefits from the build configuration already provided. It focuses on three tasks:

• Building S2I images
• Creating OpenShift resources
• Deploy application on OpenShift

Usage

To enable openshift maven plugin on your project just add this to the plugins sections of your pom.xml:

      <plugin>
        <groupId>io.jshift</groupId>
        <artifactId>openshift-maven-plugin</artifactId>
        <version>${jshift.openshift.version}</version>
      </plugin>

Goal	Description
openshift:resource	Create OpenShift resource descriptors
openshift:build	Build Docker images
openshift:push	Push Docker images to a registry
openshift:deploy	Deploy OpenShift resource objects to a cluster
openshift:watch	Watch for doing rebuilds and restarts

Features

• Dealing with S2I images and hence inherits its flexible and powerful configuration.
• Supports both 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.
• Flexible customization:
  • Generators analyze the Maven build and generated automatic Docker image configurations for certain systems (spring-boot, plain java, karaf ...)
  • Enrichers extend the 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
