Usage

$ ruby ./instance_to_elb.rb

Output

The output is a JSON containing the mapping of LB->instances as well as Instance->LBs.

Get list of instances in the VPC:

[evan@Evan ~] $ aws ec2 describe-instances --filter Name=vpc-id,Values=vpc-id | jq '[.Reservations[] | .Instances[] | .InstanceId ] | join(",")'

Get the list of volumes attached to those instances:

[evan@Evan ~] $ aws ec2 describe-volumes --filters Name=attachment.instance-id,Values=i-abcd,i-abce,i-abcf,i-abcg

Paste result into this command:

What is it?

It's a script that renames all your EBS volumes to the name+device of the EC2 instance they're attached to. It also applies the "environment" tag to each volume, read from the instance. (I use the 'environment' tag in billing reports.)

So if your instance's "Name" tag is backend-1234.prod.example.com and the volume is mapped to /dev/sdh, this script would apply the tag Name=backend-1234-prod-example-com-dev-sdh to the volume, and set the environment tag to match the instance's.

#/bin/bash
# To audit, I tried the bash script here https://gist.github.com/aastaneh/46ceb03150e5284b8a3a but it didn't work, 
# so here's my version.  It doesn't attempt to check internal ELBs (prefixed with 'internal').

for ELB in $( aws elb describe-load-balancers | grep DNSName | awk '{ print $2 }' | perl -ne 'chomp; $_  =~ /\"([\w-\.]+)\",/; my $elb = $1; print "$elb " unless $elb =~ /^internal/'); do
  echo "$ELB ";
  echo "01 logout" | openssl s_client -ssl3 -connect $ELB:443 2>&1 | grep DONE &> /dev/null
