title: SSL error CERTIFICATE_VERIFY_FAILED with Locust when using Docker
body: <p>It's my first try at Locus, and unfortunately I don't know Python.</p>
  
  <p>I'm trying a simple request to a valid https server, and I see this error:</p>
  
  <blockquote>
    <p>SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to
    get local issuer certificate</p>
  </blockquote>
  
  <p>After some research I tried to add this:</p>
  
  <pre><code>import gevent
  import geventhttpclient.connectionpool
  
  geventhttpclient.connectionpool.SSLConnectionPool.default_options = {
      "cert_reqs": gevent.ssl.CERT_NONE,
  }
  </code></pre>
  
  <p>or this:</p>
  
  <pre><code>import requests
  requests.packages.urllib3.disable_warnings() # disable SSL warnings
  </code></pre>
  
  <p>I run Locust as instructed:</p>
  
  <pre><code>docker-compose up --scale worker=4
  </code></pre>
  
  <p>How can I test https sites with Locust?</p>
  
  <p>Thanks in advance</p>
  
  <p>Regards</p>
