While looking through several examples I found a few good links on how to create a new Virtual machine(VM) using the Ruby programming language, and the digital ocean gem they provide.
They all however left off one important point out, that you have to specify the SSH key id number as part of the call to create a new VM.
Without this last extra bit of the puzzle , you end up with a VM that is up and running, but you can't use your ssh keys to log into.
- not ideal ;-)
The ssh keys have to be specified as a ruby array, as you could want more than one ssh key associated with your VM's once they have been created - so here is an example - with the missing piece inserted. The token mentioned in this code segment - is your oauth token that you create when you set up your digital ocena account. You can set it up as an env variable - but I have not shown how to do this here.
To start you need to install this gem into your Ruby environment
gem install droplet_kit
#!/usr/bin/ruby
require 'droplet_kit'
token=ENV['Oauth_key']
client = DropletKit::Client.new(access_token: token)
droplet = DropletKit::Droplet.new(name: 'example.com', region: 'nyc3', size: '1gb', image: 'ubuntu-14-04-x64', ssh_keys: [1234567])
client.droplets.create(droplet)
The code is downloadable from Github gist link below.
You can find out the id number of your ssh keys with the following bash script , so that you know which id's to put into the array.
curl -X GET -H 'Content-Type: application/json' -H "Authorization: Bearer $TOKEN" "https://api.digitalocean.com/v2/account/keys" | jq "."
Where $TOKEN is you oAuth API v2 key.
Hope this saves you time getting this up and running.
