title: Kitchen and Kitchen-docker
body: <p>I am trying to use <a href="https://github.com/test-kitchen/kitchen-docker" rel="nofollow noreferrer">kitchen-docker</a> driver on a GNU/Linux machine. I have installed the <code>kitchen-docker</code> gem using <code>chef gem install</code> command.</p>
  
  <p>This is an extract of my <code>.kitchen.yml</code> file:</p>
  
  <pre><code>---
  driver:
    name: docker
  
  provisioner:
    name: chef_zero
  
  verifier:
    name: inspec
  
  platforms:
    - name: centos-7.2
      driver_config:
        image: centos:7.2
        platform: centos
  
  suites:
    - name: zaz
      run_list:
        - recipe[foo::bar]
  ...
  ...
  </code></pre>
  
  <p>I have <code>Docker</code> installed on it's latest version using Docker repositories for Centos. The service is running and <code>Docker</code> is in my path. However when I try to run a simple <code>kitchen list</code> using that <code>.kitchen.yml</code> I get this error:</p>
  
  <pre><code>[FakeyMcFakeFace@workstation foo]$ kitchen list
  &gt;&gt;&gt;&gt;&gt;&gt; ------Exception-------
  &gt;&gt;&gt;&gt;&gt;&gt; Class: Kitchen::UserError
  &gt;&gt;&gt;&gt;&gt;&gt; Message: You must first install the Docker CLI tool http://www.docker.io/gettingstarted/
  &gt;&gt;&gt;&gt;&gt;&gt; ----------------------
  &gt;&gt;&gt;&gt;&gt;&gt; Please see .kitchen/logs/kitchen.log for more details
  &gt;&gt;&gt;&gt;&gt;&gt; Also try running `kitchen diagnose --all` for configuration
  </code></pre>
  
  <p>Why is docker not being recognized by Kitchen? If I run the <code>diagnose -all</code> option I just see it is failing on the dependencies check:</p>
  
  <pre><code>backtrace:
  - "/home/FakeyMcFakeFace/.chefdk/gem/ruby/2.3.0/gems/kitchen-docker-2.6.0/lib/kitchen/driver/docker.rb:93:in
    `rescue in verify_dependencies'"
  </code></pre>
  
  <p>What am I missing here?</p>
