title: pull artifactory docker image
body: <p>I am not able to pull Artifactory docker image using below command</p>
  
  <pre><code>docker pull jfrog-docker-reg2.bintray.io/jfrog/artifactory-pro:latest
  </code></pre>
  
  <p>It ends up with below error</p>
  
  <pre><code>Error response from daemon: invalid registry endpoint https://jfrog-docker-reg2.bintray.io/v0/: unable to ping registry endpoint https://jfrog-docker-reg2.bintray.io/v0/
  v2 ping attempt failed with error: Get https://jfrog-docker-reg2.bintray.io/v2/: dial tcp 119.81.184.206:443: i/o timeout
   v1 ping attempt failed with error: Get https://jfrog-docker-reg2.bintray.io/v1/_ping: dial tcp 119.81.184.206:443: i/o timeout. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry jfrog-docker-reg2.bintray.io` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/jfrog-docker-reg2.bintray.io/ca.crt
  </code></pre>
  
  <p>What shall I do here? Why its asking for certificate? and if I access the link of JFrog repo, it asks for username and password. How can I get this image.</p>
  
  <p>I was following official link of Artifactory to do this.<a href="https://www.jfrog.com/confluence/display/RTF/Running+with+Docker" rel="nofollow">https://www.jfrog.com/confluence/display/RTF/Running+with+Docker</a>. I searched on net but no solution.</p>
