| <h2 id="introduction">1. Introduction</h2> |
| <div class="sectionbody"> |
| <div class="paragraph"> |
| <p>The <strong>openshift-maven-plugin</strong> brings your Java applications on to |
| <a href="https://www.openshift.com/">OpenShift</a>. |
| It provides a tight integration into <a href="http://maven.apache.org">Maven</a> and benefits from the build configuration already provided. |
| This plugin focus on two tasks: <em>Building Docker images</em> and <em>creating Kubernetes resource descriptors</em>. |
| It can be configured very flexibly and supports multiple configuration models for creating: A <em>Zero-Config</em> setup allows for a quick ramp-up with some opinionated defaults. |
| For more advanced requirements, an <em>XML configuration</em> provides additional configuration options which can be added to the <code>pom.xml</code>. |
| For the full power, in order to tune all facets of the creation, external <em>resource fragments</em> and <em>Dockerfiles</em> can be used.</p> |
| </div> |
| <div class="sect2"> |
| <h3 id="building-images">1.1. Building Images</h3> |
| <div class="paragraph"> |
| <p>The <a href="#jkube:build"><strong>oc:build</strong></a> goal is for creating Docker images containing the actual application. These then can be deployed later on Kubernetes or OpenShift. |
| It is easy to include build artifacts and their dependencies into these images. |
| This plugin uses the assembly descriptor format similar to the one used in |
| <a href="http://maven.apache.org/plugins/maven-assembly-plugin/">maven-assembly-plugin</a> to specify the content which will be added |
| to the image. |
| That images can then be pushed to public or private Docker registries with <a href="#jkube:push"><strong>oc:push</strong></a>.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Depending on the operational mode, for building the actual image either a Docker daemon is used directly or an <a href="https://docs.openshift.com/enterprise/3.0/architecture/core_concepts/builds_and_image_streams.html#docker-build">OpenShift Docker Build</a> is performed.</p> |
| </div> |
| <div class="paragraph"> |
| <p>A special <a href="#jkube:watch"><strong>oc:watch</strong></a> goal allows for reacting to code changes to automatically recreate images or copy new artifacts into running containers.</p> |
| </div> |
| </div> |
| <div class="sect2"> |
| <h3 id="resource-descriptors">1.2. Kubernetes Resources</h3> |
| <div class="paragraph"> |
| <p>Kubernetes resource descriptors can be created or generated from <a href="#jkube:resource"><strong>oc:resource</strong></a>. |
| These files are packaged within the Maven artifacts and can be deployed to a running orchestration platform with <a href="#jkube:apply"><strong>oc:apply</strong></a>.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Typically you only specify a small part of the real resource descriptors which will be enriched by this plugin with various extra information taken from the <code>pom.xml</code>. |
| This drastically reduces boilerplate code for common scenarios.</p> |
| </div> |
| </div> |
| <div class="sect2"> |
| <h3 id="_configuration">1.3. Configuration</h3> |
| <div class="paragraph"> |
| <p>As mentioned already there are three levels of configuration:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p><strong>Zero-Config</strong> mode makes some very opinionated decisions based on what is present in the pom.xml like what base image to use or which ports to expose. |
| This is great for starting up things and for keeping quickstart applications small and tidy.</p> |
| </li> |
| <li> |
| <p><strong>XML plugin configuration</strong> mode is similar to what <a href="https://dmp.fabric8.io/#example">docker-maven-plugin</a> provides. |
| This allows for type-safe configuration with IDE support, but only a subset of possible resource descriptor features is provided.</p> |
| </li> |
| <li> |
| <p><strong>Kubernetes & OpenShift resource fragments</strong> are user provided YAML files that can be <em>enriched</em> by the plugin. This allows expert users to use a plain configuration file with all their capabilities, but also to add project specific build information and avoid boilerplate code.</p> |
| </li> |
| </ul> |
| </div> |
| <div class="paragraph"> |
| <p>The following table gives an overview of the different models</p> |

| <p>The XML resource configuration is based on plain Kubernetes resource objects. When targeting OpenShift, Kubernetes resource descriptors will be automatically converted to their OpenShift counterparts, e.g. a Kubernetes <a href="http://kubernetes.io/docs/user-guide/deployments/">Deployment</a> will be converted to an OpenShift <a href="https://docs.openshift.com/container-platform/4.1/applications/deployments/what-deployments-are.html#deployments-and-deploymentconfigs_what-deployments-are">DeploymentConfig</a>.</p> |

| <h4 id="_resource_fragments">1.4.3. Resource Fragments</h4> |
| <div class="paragraph"> |
| <p>The third configuration option is to use an external configuration in form of YAML resource descriptors which are located in the <code>src/main/jkube</code> directory. Each resource gets its own file, which contains a skeleton of a resource descriptor. The plugin will pick up the resource, enrich it and then combine all to a single <code>kubernetes.yml</code> and <code>openshift.yml</code> file. Within these descriptor files you are can freely use any Kubernetes feature.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Note: In order to support simultaneously both OpenShift and Kubernetes, there is currently no way to specify OpenShift-only features this way, though this might change in future releases.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Let’s have a look at an example from |
| <a href="https://github.com/eclipse/jkube/tree/master/quickstarts/maven/external-resources">quickstarts/maven/external-resources</a>. |
| This is a plain Spring Boot application, whose images are auto generated like in the <a href="#zero-config">Zero-Config</a> case. |
| The resource fragments are in <code>src/main/jkube</code>.</p> |

| <p>As you can see, there is no <code>metadata</code> section as would be expected for Kubernetes resources because it will be automatically added by the <code>openshift-maven-plugin</code>. The object’s <code>Kind</code>, if not given, is automatically derived from the |
| filename. In this case, the <code>openshift-maven-plugin</code> will create a <code>Deployment</code> because the file is called <code>deployment.yml</code>. Similar mappings between file names and resource type exist for each supported resource kind, the |
| complete list of which (along with associated abbreviations) can be found in the <a href="#appendix-kind-mapping">Appendix</a>.</p> |

| <td class="content"> |
| Now that sidecar containers are supported in this plugin(if <code>jkube.sidecar</code> is enabled), be careful whenever you’re supplying container name in the resource fragment. If container specified in resource fragment doesn’t have a name or it’s name is equal to default fmp generated application’s container name; it would not be treated as sidecar and it would be merged into main container. However, You can override plugin’s default name for main container via <code>jkube.generator.alias</code> property. |

| <div class="paragraph"> |
| <p>Additionally, if you name your fragment using a name prefix followed by a dash and the mapped file name, the plugin will automatically use that name for your resource. So, for example, if you name your deployment fragment |
| <code>myapp-deployment.yml</code>, the plugin will name your resource <code>myapp</code>. In the absence of such provided name for your resource, a name will be automatically derived from your project’s metadata (in particular, its <code>artifactId</code> as specified in your POM).</p> |
| </div> |
| <div class="paragraph"> |
| <p>No image is also referenced in this example because the plugin also fills in the image details based on the configured image you are building with (either from a generator or from a dedicated image plugin configuration, as seen before).</p> |
