Chef known_host LWRP

The Chef known_host LWRP exposes an LWRP for adding hosts and keys to the /etc/ssh_known_hosts file.

Requirements

An operating system that supports /etc/ssh_known_hosts

Usage

This LWRP is pretty freakin' simple:

known_host 'github.com'

This will append an entry in /etc/ssh_known_hosts like this:

# github.com SSH-2.0-OpenSSH_5.5p1 Debian-6+squeeze1+github8
github.com ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAq2A7hRGmdnm9tUDbO9IDSwBK6TbQa+PXYPCPy6rbTrTtw7PHkccKrpp0yVhp5HdEIcKr6pLlVDBfOLX9QUsyCOV0wzfjIJNlGEYsdlLJizHhbn2mUjvSAHQqZETYP81eFzLQNnPHt4EVVUh7VfDESU84KezmD5QlWpXLmvU31/yMf+Se8xhHTvKSCZIFImWwoG6mbUoWf9nzpIoaSjB+weqqUUmpaaasXVal72J+UX2B+2RPW3RcT0eOzQgqlJL3RKrTJvdsjE3JEAvGq3lGHSZXy28G3skua2SmVi/w4yCE6gbODqnTWlg7+wC604ydGXA8VJiS5ap43JXiUFFAaQ==

You can optionally specify your own key, if you don't want to use ssh-keyscan:

known_host 'github.com' do
  key 'node.example.com ssh-rsa ...'
end
