#bootstrap(new_attributes = {}) ⇒ Object

Note:

When booting without ssh_keys set, bootstrapping will wait until the server is read and not until you can ssh into the server Bootstrapping waits until bootstap_timeout seconds and then destroy the server. Default timeout is 120 seconds, which should be ok unless you have a lot of user-data scripts.

Sets the proc used to determine the IP Address used for ssh/scp interactions.

Examples:

service.servers.bootstrap :name => "bootstrap-server",
                          :image => service.flavors.first.id,
                          :server_type => service.server_types.all(:name => 'cx11').identity,
                          :private_key_path => "~/.ssh/fog_rsa",
                          :user_data => "./file",
                          :location => 'nbg1',
                          :ssh_keys => [ 'keyname' ],
                          :bootstap_timeout => 120
