How to know ip address of nodes under ELB in AWS

Question

我在具有4个节点上的公共ELB的VPN中运行我的应用程序，我想知道该ELB后面所有节点的ipAddress。

Answer 1

You Can Create a CLI Script .

Using the AWS CLI -

Pass the ELB name to describe the LoadBalancer.

aws elb describe-load-balancers --load-balancer-name sarat-load-balancer

It returns a set of instance id running behind the load balancer in Json Format. Extract the Instance ids and Put them in a Loop .

Pass the Instance ids to describe the Instance.

aws ec2 describe-instances --instance-ids i-xxxxxxxxxx

It returns a set of data with public ips of the instances in Json Format.

You can do the same with SDK .

Hope It Helps.. :)
