io.fabric8插件生成kubernetes和openshift yaml

Question

当我包含targetDir配置时，io.fabric8会生成kubernetes和openshift yaml

<plugin>
  <groupId>io.fabric8</groupId>
  <artifactId>fabric8-maven-plugin</artifactId>
  <version>4.3.1</version>
  <configuration>
    <targetDir>${basedir}/fabric8/</targetDir>
  </configuration>
</plugin>

默认情况下，它会转到target/fabric8/deployment.yaml我想让它转到{basedir}/fabric8/，而不会生成额外的文件夹和文件，只需要/deployment.yaml，这是我运行mvn fabric8:resource的命令

我是Fabric8团队的。Fabric8 Maven插件有一个选项fabric8.targetDir，您可以使用该选项覆盖默认的目标目录。以下是它在您的用例中的工作方式：

~/work/repos/fmp-demo-project : $ mkdir fabric8
~/work/repos/fmp-demo-project : $ mvn fabric8:resource -Dfabric8.targetDir="./fabric8"

不幸的是，Kubernetes插件同时为Fabric8和Openshift生成资源描述符。在Kubernetes的情况下，它也会生成一个默认的Service，如果你想禁用它，你可以像这样配置插件来禁用Service Enricher：

            <plugin>
                <groupId>io.fabric8</groupId>
                <artifactId>fabric8-maven-plugin</artifactId>
                <version>4.3.1</version>
                <configuration>
                   <enricher>
                     <excludes>
                       <exclude>fmp-service</exclude>
                     </excludes>
                   </enricher>
                </configuration>
            </plugin>

这样，在资源生成阶段就不会生成Service，只剩下Deployment了。以下是插件配置后的运行：

"/work/repos/fmp-demo-project : $ mvn fabric8:resource -Dfabric8.targetDir="./fabric8

我们一直在重构/重塑FMP为两个不同的插件，你可以在这里找到它：Eclipse Jkube，它有两个插件- Kubernetes Maven Plugin和Openshift Maven Plugin。它们只分别生成Kubernetes或Openshift清单。这样，您只能生成似乎适合您当前用例的Kubernetes资源。

希望这能有所帮助。
