### Managing multiple ssh key pairs
The key pair you've specified, will be registered as "fog_default" after running `bootstrap` for the first time. If you want to use multiple key pairs with the same AWS credentials, you need to set `Fog.credential` to register your other key pairs under different names. Your additional key pair will then be registered as "fog_#{Fog.credential}":
Fog.credential = 'my_custom_key'
connection.servers.bootstrap(:private_key_path => '~/.ssh/my_custom_key', :public_key_path => '~/.ssh/my_custom_key.pub')
If you've already registered a custom key pair e.g. using `connection.create_key_pair` or `connection.import_key_pair`, you can set your key paths using `Fog.credentials` and pass in the name of this key so `bootstrap` will use it instead of "fog_default":
Fog.credentials = Fog.credentials.merge({ :private_key_path => "~/.ssh/my_custom_key", :public_key_path => "~/.ssh/my_custom_key.pub" })
connection.import_key_pair('my_custom_key', IO.read('~/.ssh/my_custom_key.pub')) if connection.key_pairs.get('my_custom_key').nil?
server = connection.servers.bootstrap(:key_name => 'my_custom_key')
