使用Arquillian Cube在Docker上运行Java EE测试

技术提示＃61展示了如何使用Docker运行Java EE 7动手实验室。 在那里使用的Dockerfile可用于创建新映像，该映像可将任何Java EE 7 WAR文件部署到容器中运行的WildFly实例。

例如，可以将github.com/arun-gupta/docker-images/blob/master/javaee7-test/Dockerfile复制到javaee7-samples的根目录，并用于将jaxrs-client.war文件部署到容器中。 当然，您首先需要将示例构建为：

mvn -f jaxrs/jaxrs-client/pom.xml clean package -DskipTests

确切的Dockerfile显示在这里：

FROM arungupta/wildfly-centos
ADD jaxrs/jaxrs-client/target/jaxrs-client.war /opt/wildfly/standalone/deployments/

如果要部署另一个Java EE 7应用程序，则需要执行以下步骤：

• 创建示例的WAR文件
• 更改Dockerfile
• 建立形象
• 停止上一个容器
• 启动新容器

现在，如果您要针对该实例运行测试，则仅mvn test不会执行此操作，因为您需要静态绑定Docker容器的IP地址，或者动态地找到该地址，然后在运行时对其进行修补。 无论如何，重复的循环太麻烦了。 您如何解决？

认识Arquillian Cube ！

Arquillian Cube允许您自动或手动地将Docker映像的生命周期作为测试生命周期的一部分进行控制。

该博客条目提供了有关Arquillian Cube 入门的更多详细信息，并且现在已在javaee7-samples的“ docker”分支中启用了此功能。 Arquillian Cube Extension Alpha2 最近发布 ，用于提供集成。 以下是关键概念：

• 正在引入新的“ wildfly-docker-arquillian”配置文件
• 该配置文件增加了对以下项的依赖

  
      org.arquillian.cube
      arquillian-cube-docker
      1.0.0.Alpha2
      test
  

• 使用Docker REST API与容器对话。 完整的API文档显示了示例负载，并解释了查询参数和状态代码。
• 使用WildFly远程适配器与容器中运行的应用程序服务器通信
• Docker映像的配置被指定为maven-surefire-plugin的一部分：

  
      
      wildfly-docker
      admin
      Admin#70365
      1.15
      http://127.0.0.1:2375
      
          wildfly-docker:
              image: arungupta/javaee7-samples-wildfly
              exposedPorts: [8080/tcp, 9990/tcp]
              await:
                  strategy: polling
                  sleepPollingTime: 50000
                  iterations: 5
              portBindings: [8080/tcp, 9990/tcp]
      
      
  

  在arungupta / javaee7-samples-wildfly映像中为WildFly指定了用户名和密码。 每个测试用例都可以使用arquillian.xml覆盖所有配置值，如此处所述 。

您如何尝试此功能？

git clone https://github.com/javaee-samples/javaee7-samples.git
git checkout docker
mvn test -f servlet/simple-servlet/pom.xml -Pwildfly-docker-arquillian

这是运行simple-servlet测试的完整日志：

此处显示了从客户端到Docker服务器的REST有效负载。 已在Fedora 20 Virtual Box映像上对此进行了验证。 以下是在此处进行设置的一些简要说明：

1. 安装所需的软件包

   yum install docker-io git maven
   yum upgrade selinux-policy

2. 配置Docker

   sudo vi /etc/sysconfig/docker
   Change to "OPTIONS=--selinux-enabled -H tcp://127.0.0.1:2375 -H unix:///var/run/docker.sock"
   sudo service docker start

3. 验证Docker TCP配置

   docker -H tcp://127.0.0.1:2375 version
