Let's say your security team is doing routine scanning and they find that a few of your OpenStack instances running in your cloud are not passing the security test, what do you do?
You whip up a quick and dirty bash script that takes the floating ip address as an argument and then provides the name of the tenant that ip address belongs to:
#!/bin/bash
FLOAT=`neutron floatingip-list |grep $1|awk -F '|' {'print $2'}`
TENANT=`neutron floatingip-show $FLOAT|grep tenant|awk -F '|' {'print $3'}`
keystone tenant-get $TENANT
Sample run:
./float2tenant.sh 10.63.10.193
