pull artifactory docker image

Question

I am not able to pull Artifactory docker image using below command

docker pull jfrog-docker-reg2.bintray.io/jfrog/artifactory-pro:latest

It ends up with below error

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

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.

I was following official link of Artifactory to do this.https://www.jfrog.com/confluence/display/RTF/Running+with+Docker. I searched on net but no solution.

Solution

Update 2017: the documentation now mentions:

docker pull docker.bintray.io/jfrog/artifactory-pro:latest 

See "JFrogDev/artifactory-docker-examples issue 1", in Feb. 2017:

You should use the docker.bintray.io tag.
It's simply an alias to frog-docker-reg2.bintray.io, so you can't go wrong.
