This repo follows along with https://github.com/groovemonkey/digitalocean-terraform
A small change I made was to have the Digital Ocean API Key in a separate file,
rather than in plain text inside variables.tf
I made this change mostly so I wouldn't have to worry about accidentally committing my key to this repository.
To make that work, it was necessary to remove the newline character with:
truncate -s -1 /home/thewithz/do-tf-project/keys/do_token
Another small change was to the providers.tf where I query the ssh fingerprint from digital ocean rather than defining it in the config.
