将 ModifyTargetGroup 与 CLI 配合使用

修改目标组的运行状况检查配置

以下 modify-target-group 示例更改用于评估指定目标组的目标运行状况的运行状况检查的配置。请注意，由于 CLI 解析逗号的方式不同，您必须用单引号（而不是双引号）将 --matcher 选项的范围引起来。

aws elbv2 modify-target-group \
    --target-group-arn arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-https-targets/2453ed029918f21f \
    --health-check-protocol HTTPS \
    --health-check-port 443 \
    --matcher HttpCode='200,299'

输出：

{
    "TargetGroups": [
        {
            "TargetGroupArn": "arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-https-targets/2453ed029918f21f",
            "TargetGroupName": "my-https-targets",
            "Protocol": "HTTPS",
            "Port": 443,

            "HealthCheckIntervalSeconds": 30,
            "HealthCheckTimeoutSeconds": 5,
            "HealthyThresholdCount": 5,
            "UnhealthyThresholdCount": 2,
            "Matcher": {
                "HttpCode": "200,299"
            },
            "LoadBalancerArns": [
                "arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/app/my-load-balancer/50dc6c495c0c9188"
            ],
            "TargetType": "instance",
            "ProtocolVersion": "HTTP1",
            "IpAddressType": "ipv4"
        }
    ]
}
