如何从AWS SDK for Java克隆Elastic Beanstalk环境？

Question

我需要从AWS SDK for Java克隆Elastic Beanstalk环境。

我找到this解答如何创建环境，但我找不到任何示例或文档来说明如何克隆环境。

我为clone找到了CreateEnvironmentRequest方法，但根据documentation，它克隆了CreateEnvironmentRequest对象，而不是环境。

Answer 1

已经为此打开了issue，因为现在无法从sdk进行克隆操作。如果您有兴趣，可能需要重新打开故障单并提供理由。

另一种可能性是从Java调用eb cli来运行环境的克隆。

好吧，你无法使用Java SDK for AWS完全克隆环境，我的方法是每次只创建一个新环境，你可以这样做：

1. 将您的部署文件（war，zip）上传到S3

2. 为您的部署创建一个链接到以前上传的文件的版本

   private CreateApplicationVersionRequest createApplicationVersion() {
       return new CreateApplicationVersionRequest()
               .withApplicationName("The app name")
               .withAutoCreateApplication(true)
               .withSourceBundle(new S3Location("bucket_name", deployedArtifactId))
               .withVersionLabel("a number for the version");
   }
   

3. 您去寻找最新版本的堆栈

   private void getLatestStackSolutionVersion() {
       ListAvailableSolutionStacksResult response = beanstalkClient.listAvailableSolutionStacks();
       for (int i = 0; i < response.getSolutionStacks().size(); i++) {
           if (response.getSolutionStacks().get(i).contains("Java 8") {
               stackName = response.getSolutionStacks().get(i);
               break;
           }
       }    
   }
   

4. 配置环境，系统属性和所有内容的属性。

   private Collection<ConfigurationOptionSetting> setEnvironmentProperties() {
       Collection<ConfigurationOptionSetting> configurationOptionSettings = new HashSet<>();
       configurationOptionSettings.add(new ConfigurationOptionSetting("aws:autoscaling:launchconfiguration", "InstanceType", "t2.medium"));
       configurationOptionSettings.add(new ConfigurationOptionSetting("aws:ec2:vpc", "VPCId","thevpcid");
       configurationOptionSettings.add(new ConfigurationOptionSetting("aws:ec2:vpc", "Subnets", "thesubnets");
       configurationOptionSettings.add(new ConfigurationOptionSetting("aws:ec2:vpc", "ELBSubnets", "theelbsubnets");
       configurationOptionSettings.add(new ConfigurationOptionSetting("aws:elasticbeanstalk:application:environment", "ANOTHER_PROPERTY", "a value"));
       return configurationOptionSettings;
   }
   

5. 创建一切准备就绪的环境。

   public void deployCreatingEnvironment() {
       getLatestStackSolutionVersion();
       beanstalkClient.createApplicationVersion(createApplicationVersion());
       beanstalkClient.createEnvironment(setupNewEnvironment());
   }
   

瞧！这就像每次克隆一样，希望这对你有用。
