To describe target group attributes

The following describe-target-group-attributes example displays the attributes of the specified target group.

aws elbv2 describe-target-group-attributes \
    --target-group-arn arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/73e2d6bc24d8a067

The output includes the attributes if the protocol is HTTP or HTTPS and the target type is instance or ip.

{
    "Attributes": [
        {
            "Value": "false",
            "Key": "stickiness.enabled"
        },
        {
            "Value": "300",
            "Key": "deregistration_delay.timeout_seconds"
        },
        {
            "Value": "lb_cookie",
            "Key": "stickiness.type"
        },
        {
            "Value": "86400",
            "Key": "stickiness.lb_cookie.duration_seconds"
        },
        {
            "Value": "0",
            "Key": "slow_start.duration_seconds"
        }
    ]
}

The following output includes the attributes if the protocol is HTTP or HTTPS and the target type is lambda.

{
    "Attributes": [
        {
            "Value": "false",
            "Key": "lambda.multi_value_headers.enabled"
        }
    ]
}

The following output includes the attributes if the protocol is TCP, TLS, UDP, or TCP_UDP.

{
    "Attributes": [
        {
            "Value": "false",
            "Key": "proxy_protocol_v2.enabled"
        },
        {
            "Value": "300",
            "Key": "deregistration_delay.timeout_seconds"
        }
    ]
}
