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?
