fabric8：添加配置映射
fabric8: Add a configmap
我已经能够使用 fabric8 插件构建 spring 引导服务映像并将其部署到 openshift 中。
我需要添加一些配置映射。
我尝试将 striaghtforward configmap.yml 添加到 src/main/fabric8。
目前，我收到这条消息：

我的configmap.yml是：
data:
application.properties: |
spring.profiles.active=dev
我目前相关的pom.xml配置是：
<build>
<plugins>
<plugin>
<groupId>io.fabric8</groupId>
<artifactId>fabric8-maven-plugin</artifactId>
<version>4.4.1</version>
</plugin>
</plugins>
</build>
它是基于零配置的。
关于如何添加我的 configmap.yml 的任何想法？

正如我在评论中提到的，您应该尝试切换到 Eclipse JKube since it's going to be supported in future. Migrating to Eclipse JKube 就像 运行 这个目标一样简单：
$ mvn org.eclipse.jkube:kubernetes-maven-plugin:migrate
我在 my demo projects:
之一中用这个版本的 kubernetes-maven-plugin 试用了你的 ConfigMap 资源片段
<plugin>

当我执行 mvn k8s:resource k8s:apply 时，我能够看到正在创建 ConfigMap：
