fabric8:添加配置映射

Question

我已经能够使用fabric8插件构建我的spring引导服务镜像并将其部署到openshift中。

我需要添加一些configmap。

我曾尝试在src/main/fabric8中添加一个striaghtforward configmap.yml。

目前，我收到了这样的消息：

[INFO] --- fabric8-maven-plugin:4.4.1:resource (default-cli) @ connector ---
[INFO] F8: Using Container image name of namespace: arxius-linia

我的configmap.yml是：

data:
  application.properties: |
    spring.profiles.active=dev

我当前相关的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>

它基于零配置。

关于如何添加我的configmap.yml有什么想法吗

我来自Fabric8/Eclipse JKube团队。

正如我在评论中提到的，你应该尝试切换到Eclipse JKube，因为它将在未来得到支持。Migrating to Eclipse JKube就像运行这个目标一样简单：

$ mvn org.eclipse.jkube:kubernetes-maven-plugin:migrate

我用这个版本的kubernetes-maven-plugin在一个my demo projects中试用了您的ConfigMap资源片段

      <plugin>
        <groupId>org.eclipse.jkube</groupId>
        <artifactId>kubernetes-maven-plugin</artifactId>
        <version>1.1.0</version>
        <executions>
          <execution>
            <goals>
              <goal>resource</goal>
            </goals>
          </execution>
        </executions>
      </plugin>

我在我的src/main/jkube目录中添加了你的ConfigMap：

eclipse-jkube-sample-with-resource-fragments : $ cat src/main/jkube/second-configmap.yaml 
data:
  application.properties: |
    spring.profiles.active=dev

当我做mvn k8s:resource k8s:apply时，我能够看到ConfigMap是如何创建的：

eclipse-jkube-sample-with-resource-fragments : $ mvn k8s:resource k8s:apply

当我检查时，我能够看到在default名称空间中创建的ConfigMap：

eclipse-jkube-sample-with-resource-fragments : $ kubectl get configmap second -o yaml
apiVersion: v1
data:
  application.properties: |
    spring.profiles.active=dev
kind: ConfigMap
