Locate a floating ip ID. This can be done by name

 doex floating_ip.id <droplet_name>

Or, by tag

doex floating_ip.id <tag> --tag

If by tag, it will grab the latest

For example

doex floating_ip.id my_app

If you have a specific config file, mix help doex.config then add it as an environment variable

DOEX_CONFIG=/tmp/my.doex doex floating_ip.id my_app
