User-added image

For example, as regards the following Centos image, when you perform a Docker pull:

docker pull docker.jfrog.com:8081/centos:latest
Error response from daemon: manifest for docker.jfrog.com:8081/centos:latest not found

The request.log shows: 

20190306113853|2242|REQUEST|127.0.0.1|anonymous|GET|/api/docker/docker/v2/centos/manifests/latest|HTTP/1.1|404|0


As the Docker hub only supports token-based authentication, in the UI for Arifactory's docker-remote repository options, you"ll need to tick the Enable Token Authentication( see screenshot below) to enable the execution of Docker pulls.

User-added image

Following this, the docker pull example above should work as expected.

docker pull docker.jfrog.com:8081/centos:latest

latest: Pulling from centos
