title: Terraform - cannot source module from github
body: <p>I am trying to source a terraform module from github like so:</p>
  <pre><code>module &quot;example&quot; {
    source = &quot;https://github.com/cloudposse/terraform-example-module.git?ref=master&quot;
    example = &quot;Hello world!&quot;
  }
  </code></pre>
