io.fabric8插件生成Kubernetes和Openshift YAML

Question

io.fabric8 在包含 targetDir 配置时生成 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，它转到 转到target/fabric8/deployment.yaml我希望它转到{basedir}/fabric8/，而不会生成一些额外的额外文件夹和文件，只是/deployment.yaml，这是我运行的命令mvn fabric8:resource

我来自Fabric8团队。Fabric8 Maven插件有一个选项fabric8.targetDir您可以使用它覆盖默认目标目录。以下是它应该如何为您的用例工作：

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

不幸的是，Fabric8 Maven插件为Kubernetes和Openshift生成资源描述符。在 Kubernetes 的情况下，它也会生成一个默认Service，如果你想禁用它，你可以像这样配置插件来禁用服务丰富器：

<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Service就不会在资源生成阶段生成，你只剩下Deployment。这是插件配置后的运行：

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

我们一直在将FMP重构/重塑为两个不同的插件，你可以在这里找到它：Eclipse Jkube，它有两个插件 - Kubernetes Maven插件和Openshift Maven插件。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。

希望有帮助。
