We are running low on IP addresses in a specific subnet in AWS. I was able to find all ec2 instances using IP address from this specific subnet. Now I am trying to find all Elastic Load Balancers using this subnet via the AWS CLI.
I know that I can run the following to find all ELB on a specific VPC:
aws elb describe-load-balancers --query 'LoadBalancerDescriptions[?VPCId==vpc-12345678]|[].LoadBalancerName'
I think the issue with subnets is you can have multiple subnets. So it is a list instead of just one value like VPCId.
I tried the following:
aws --region us-east-1 elb describe-load-balancers --query 'LoadBalancerDescriptions[?Subnets==subnet-1234546]|[].LoadBalancerName'
But it came back with nothing even though I can see from previous search that some ELB do have the specific subnet I am looking for. I think it is due to it being a list of subnets but I'm unsure how how to search for it.
Any ideas?
Thank you.
