As we have a value that is encrypted using the Vault, we need to run the following command to run the playbook:
$ ansible-playbook --vault-id @prompt site.yml
This will prompt for the passphrase you set to encrypt the Vault. Once you have entered the passphrase, the play will run:
PLAY [localhost] *****************************************************************************************************************************TASK [roles/droplet : upload SSH key to DigitalOcean] ****************************************************************************************changed: [localhost] => (item=ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDmuoFR01i/Yf3HATl9c3sufJvghTFgYzK/Zt29JiTqWlSQhmXhNNTh6iI6nXuPVhQGQaciWbqya6buncQ3vecISx6+EwsAmY3Mwpz1a/eMiXOgO/zn6Uf79dXcMN2JwpLFoON1f9PR0/DTpEkjwqb+eNLw9ThjH0J994+Pev+m8OrqgReFW36a/kviUYKsHxkXmkgxtPJgwKU90STNab4qyfKEGhi2w/NzECgseeQYs1H3klORaHQybhpXkoCIMmgy9gnzSH7oa2mJqKilVed27xoirkXzWPaAQlfiEE1iup+2xMqWY6Jl9qb8tJHRS+l8UcxTMNaWsQkTysLTgBAZ ...
