Adding SSH keys to a DigitalOcean account

There are two ways to log into a DigitalOcean droplet. If public key information is supplied during the creation of the droplet, then it will be added to the root user of the droplet. Otherwise, a one-time password is emailed to the registered user ID. Because of security implications, we strongly recommend using public keys and not passwords for logging in.

How to do it…

1. For adding an SSH public key to our account, we will use the digital_ocean_sshkey module:

- name: Add SSH key to DO account
  digital_ocean_sshkey:
    name: "cookbook-key"
    ssh_pub_key: "{{ ssh_public_key }}"
    oauth_token: "{{ DO_OAUTH_TOKEN }}"

We have supplied a name along with the key. We need to add the token for the authentication as well.

2. We  will store the public key in the roles/digitalocean/vars/main.yml as a variable:

--
ssh_public_key: ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCbg83WYIxUfXWJ4bQiYfZYHceDwMJxnGfJqgYtHL/DAtegVY+Nm8MX3CRZYisfskt0m9CQ6y/Ux1OITTz+O11fgxLJcroZmKJbWW0K39gfHvFqR7FIe0zuJaxqUQUuyc0i6RCBRiZPiQQOPes2yDtfHgDWx3q9knS3ZXIAXcGLZrgfC1XnIK8CLAnZDved9Rue2bhsCnO9Mleh9g...
