title: Docker push error "413 Request Entity Too Large"
body: <p>I setup the <code>registry v2</code> and use <code>nginx</code> as reverse proxy. When I push the image to registy, it error out <code>413 Request Entity Too Large</code>.</p>
  
  <p>I have modify the client_max_body_size as 20MB in nginx.conf. The push still fails.</p>
  
  <pre><code>client_max_body_size 20M;
  </code></pre>
  
  <p>What is the body size in docker push? How can I limit the body size?</p>
