运行Java >8映像的fabric8 maven插件配置

Question

我正在使用fabric8 maven插件将vertx应用程序部署到Openshift中。我的应用程序正在使用Java 11运行。

但是，默认情况下，fabric8 maven插件使用Java8Docker映像来创建我的vertx应用程序映像。

如何将fabric8 maven插件配置为使用Java11映像？它是否为Java >8提供其他映像？

Answer 1

我通过将从配置添加到生成器中，对Spring应用程序进行了修复。对于vert.x，解决方案可能如下所示：

<plugin>                                                     
    <groupId>io.fabric8</groupId>                            
    <artifactId>fabric8-maven-plugin</artifactId>            
    <version>3.5.42</version>                                
    <configuration>                                          
        <generator>                                          
            <config>                                         
                <vertx>                                      
                    <from>fabric8/s2i-java:3.0-java11</from> 
                </vertx>                                     
            </config>                                        
        </generator>                                         
    </configuration>                                         
</plugin>

可以在Docker页面上查找s2i映像可用的标记：https://hub.docker.com/r/fabric8/s2i-java/tags

对我来说，这个解决方案从上面没有帮助，但感谢！我发现我必须在我的个人资料定义中声明图像。我正在运行openshift构建，如下所示：mvn clean fabric8:deploy -P openshift对我有很大帮助，它把这个添加到了概要文件中：

  <properties>
      <fabric8.generator.fromMode>docker</fabric8.generator.fromMode>
      <fabric8.generator.from>fabric8/s2i-java:3.0-java11</fabric8.generator.from>
  </properties>

下面是我的pom.xml的一部分，有一个外观配置文件定义

<properties>
    ...
    <java.version>11</java.version>
    <maven.compiler.plugin.version>3.8.0</maven.compiler.plugin.version>
    <fabric8-maven-plugin.version>4.4.1</fabric8-maven-plugin.version>
  </properties>
