## Bootstrap
In addition to the `create` method, fog provides a method called `bootstrap`. This method creates a server and then performs the following actions via ssh:
1. Create `ROOT_USER/.ssh/authorized_keys` using the specified `:public_key`.
2. Lock password for root user using `passwd -l root`.
3. Create `ROOT_USER/attributes.json` with the server's attributes.
4. Create `ROOT_USER/metadata.json` with the server's metadata
**Note**: The `bootstrap` method is a blocking call unlike `create` method.
The following example demonstrates bootstraping a server:
service.servers.bootstrap :name => 'bootstrap-server',
:flavor_id => service.flavors.first.id,
:image_id => service.images.find {|img| img.name =~ /Ubuntu/}.id,
:public_key_path => '~/.ssh/fog_rsa.pub',
:private_key_path => '~/.ssh/fog_rsa'
**Note**: The `create` method provides an option called `:personality` that allows developers to populate files on the server without using ssh.
## SSH
Once a server has been created and setup for ssh key authentication, fog can execute remote commands as follows:
result = server.ssh ['pwd']
This will return the following:
[#<Fog::SSH::Result:0x1108241d0 @stderr="", @status=0, @stdout="/root\r\n", @command="pwd">]
**Note**: SSH key authentication can be setup using `bootstrap` method or by using the `:personality` attribute on the `:create` method. See [Bootstrap](#bootstrap) or [Create Server](#create-server) for more information.

## Metadata ## Metadata
You can access metadata as an attribute on both `Fog::Compute::RackspaceV2::Server` and `Fog::Compute::RackspaceV2::Metadata::Image`. You can specify metadata during creation of a server or an image. Please refer to [Create Server](#create-server) or [Create Image](#create-image) sections for more information.
