fabric8 maven 插件配置与映像运行 Java > 8

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。

然而，默认情况下，fabric8 maven插件使用Java 8 Docker映像来创建我的vertx应用程序映像。

如何配置fabric8 maven插件以使用Java 11映像？它是否为Java>8提供了其他图像？

Answer 1

我通过将配置中的添加到生成器中，为我的Spring Boot应用程序修复了它。对于vert.x，解决方案可能是这样的：

<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 Hub页面上查找s2i图像可用的标签：https://hub.docker.com/r/fabric8/s2i-java/tags

对我来说，上面的这个解决方案没有帮助，但感谢！我发现我必须在我的个人资料定义中声明图像。我正在像这样运行我的openshift构建：mvn clean fabric8:deploy -P openshift对我帮助很大的是将其添加到配置文件：

<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，有一个外观概要文件定义

<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>
