我正在使用 Amazon AWS ELB 命令行工具。有没有办法找到附加到特定弹性负载均衡器(ELB)的实例？

我安装了新的 AWS cli 工具:

$ pip install awscli

然后运行:

$ aws configure                                                                                                                                                
AWS Access Key ID [None]: my-key
AWS Secret Access Key [None]: my-secret
Default region name [None]: us-east-1
Default output format [None]:

此数据保存到 ~/.aws/config 中。

然后我可以找到连接到负载均衡器的实例，如下所示:

$ aws elb describe-load-balancers --load-balancer-name "my-name"
{
    "LoadBalancerDescriptions": [
        {
            "Subnets": [],

                },
                {

                        "InstanceProtocol": "HTTP"
                    },
                    "PolicyNames": [
                        "AWSConsole-SSLNegotiationPolicy-api-production"

                {
                    "InstanceId": "i-SECOND-INSTANCEID"
                }
            ],

                "AppCookieStickinessPolicies": [],
                "OtherPolicies": [
                    "AWSConsole-SSLNegotiationPolicy-my-name"
                ]
            },
            "LoadBalancerName": "my-name",
            "CreatedTime": "2013-08-05T16:55:22.630Z",
            "AvailabilityZones": [
                "us-east-1d"
            ],
            "Scheme": "internet-facing",
            "SourceSecurityGroup": {
                "OwnerAlias": "amazon-elb",
                "GroupName": "amazon-elb-sg"
            }
        }
    ]
}

数据位于LoadBalancerDescriptions.Instances中。

我的负载均衡器名为 my-name — 这是您在创建它时选择的名称。

下面是旧答案!

我不熟悉cli工具，但我使用过API。

我会检查这两个请求:

• DescribeLoadBalancers
• DescribeInstanceHealth

cli 工具可能有类似这些的东西？

呵呵!
