如何通过CLI获取AWS目标组中已注册目标的列表 [英] how to get list of registered targets in AWS target group via CLI

问题描述

我们正在尝试获取目标组中已注册目标(实例)的状态.可以使用命令 aws elbv2 describe-target-health --target-group-arn $ {TG} --targets Id = $ {ID}，Port = $ {PORT} ，参考.我们可以通过 aws ecs describe-tasks --cluster $ CLUSTER --tasks $ task 命令，

We are trying to get the state of a registered target (instance) in a target group. This can be done with the command aws elbv2 describe-target-health --target-group-arn ${TG} --targets Id=${ID},Port=${PORT}, reference. We are able to get the PORT via the aws ecs describe-tasks --cluster $CLUSTER --tasks $task command, reference. But how can the target's instance Id be retrieved via CLI?

推荐答案

这将为您提供目标组中已注册实例ID的数组.当拥有目标ARN时，为什么要使用目标ID?所以我跳过目标ID，仅使用目标ARN.

This will give you the array of registered instance ID in a target group. When you have target ARN why you using target ID? so I am skipping target ID and using just target ARN.

aws elbv2 describe-target-health --target-group-arn ${TG}  --query 'TargetHealthDescriptions[*].Target.Id'
