Question

根据业务需求，我们需要通过API调用控制AWS自动伸缩组策略。我已经阅读了Java SDK客户端文档，但是找不到与API调用相关的任何信息。我不确定这是否可行。以下是要求，

应该能够设置特定AWS自动缩放组的所需容量（在文档中。）
应该能够获得特定AWS自动缩放组的所需容量
应该能够获取特定AWS自动缩放组的最小计数
应该能够获得特定AWS自动缩放组的最大计数

通过Java SDK设置自动扩展组所需的容量。

AmazonAutoScaling client = AmazonAutoScalingClientBuilder.standard()
                .withCredentials(new ProfileCredentialsProvider(CredentialProfiles.API_MANAGER.getProfile())).build();
SetDesiredCapacityRequest request = new SetDesiredCapacityRequest()
                .withAutoScalingGroupName(autoScaleGroupNameValue).withDesiredCapacity(desiredCapacityValue)
                .withHonorCooldown(true);
        SetDesiredCapacityResult response = get().setDesiredCapacity(request);

请告知我是否可以通过AWS开发工具包Java客户端执行这些操作。

设置所需容量

AmazonAutoScaling asgClient = AmazonAutoScalingClientBuilder.standard().withCredentials(CREDENTIALS_PROVIDER).build();

SetDesiredCapacityRequest dcRequest = new SetDesiredCapacityRequest()
        .withAutoScalingGroupName("AUTO_SCALING_GROUP_NAME").withDesiredCapacity(2);
SetDesiredCapacityResult dcResult = asgClient.setDesiredCapacity(dcRequest);

要检索ASG详细信息

DescribeAutoScalingGroupsRequest asgRequest = new DescribeAutoScalingGroupsRequest()
        .withAutoScalingGroupNames("AUTO_SCALING_GROUP_NAME");
DescribeAutoScalingGroupsResult asgResult = asgClient.describeAutoScalingGroups(asgRequest);

List<AutoScalingGroup> groupList = asgResult.getAutoScalingGroups();

groupList.forEach((asgroup) -> System.out.println(asgroup.getDesiredCapacity())); // Desired Capacity
groupList.forEach((asgroup) -> System.out.println(asgroup.getMinSize())); // Min
groupList.forEach((asgroup) -> System.out.println(asgroup.getMaxSize())); // Max

如何通过AWS Java SDK客户端从Auto Scale组提取数据
