body: <p>I am trying to use cloudify fabric plugin to run a simple command. When I install the blueprint I am getting following error. </p>

  <p>My inputs.yaml is </p>
  
  <pre><code>agent_private_key_path: /root/.ssh/id_rsa
  agent_user: vagrant
  host_ip: 10.10.1.10
  </code></pre>
  
  <p>When I update my blueprint to use following then it works. But is this necessary? I mean this information is already specified in the host. Why do I need to give it again with the fabric plugin. </p>
  
  <pre><code>     fabric_env:
          host_string: { get_input: host_ip }
          user: { get_input: agent_user }
          key_filename: { get_input: agent_private_key_path }
  </code></pre>
  
  <p>Is there anything I am doing wrong. I am just the beginner in this area, so  any help will be appreciated.</p>
