Locate a droplet ID. This can be done by name

 doex droplets.id <droplet_name>

Or, by tag

doex droplets.id <tag> --tag

If by tag, it will grab the latest

For example

doex droplets.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 droplets.id my_app

There is also a more generic task that you can use to locate any resource

doex id my_app --droplets
