title: OpenWhisk action fails on local Ubuntu deployment
body: <p>I deployed OpenWhisk on a local Ubuntu machine according to the following documentation: <a href="https://github.com/openwhisk/openwhisk/blob/master/tools/ubuntu-setup/README.md" rel="nofollow noreferrer">https://github.com/openwhisk/openwhisk/blob/master/tools/ubuntu-setup/README.md</a>. However, when I try to invoke sample action with command:</p>
  
  <pre><code>wsk action invoke /whisk.system/utils/echo -p message hello --blocking --result
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>Unable to invoke action ‘utils/echo’: Post 
  https://172.17.0.1/api/v1/namespaces/whisk.system/actions/utils/echo?  
  blocking=true: dial tcp 172.17.0.1:443: getsockopt: connection refused.
  </code></pre>
  
  <p>I set my apihost to 172.17.0.1 (Docker edge host) and I’m using guest namespace with authentication from ansible/files/auth.guest. I suppose that some services should run in the Docker so that it’ll listen on the 443 port, but I have no idea what services and why are they not running.</p>
  
  <p>I would be grateful for any help.</p>
