Bug 1273412

Document URL: https://access.redhat.com/documentation/en/openshift-enterprise/version-3.0/installation-and-configuration/#access

Section Number and Name: 2.5.5. Accessing the Registry

Describe the issue: After login to docker registry it fails when pushing the image :

docker login -u adminuser -e adminuser -p EZj3BAkB1ka5MVwwtATTluJ6-5uZKBiB1e-LeE0wtHQ 172.30.233.178:5000
WARNING: login credentials saved in /root/.docker/config.json

[root@opeshift3node1 ~]# docker push 172.30.233.178:5000/openshift/busybox
The push refers to a repository [172.30.233.178:5000/openshift/busybox] (len: 1)
0064fda8c45d: Image push failed

Please login prior to push:
Username (sudhir): adminuser

Suggestions for improvement: 

Below steps helped to resolve the issue which are additional :

In order to push images into the OpenShift Docker registry, an account must have the image-builder security role. Add this to your admin user:

   # oadm policy add-role-to-user system:image-builder sudhir

- Next, add the admin (administrative) role to the user in the special “openshift” project. This will allow the admin user to be able to edit the “openshift” project - in this case, to push the Docker images.
 
    # oadm policy add-role-to-user admin sudhir -n openshift

Below steps worked perfectly fine.

 docker login -u adminuser -e adminuser -p EZj3BAkB1ka5MVwwtATTluJ6-5uZKBiB1e-LeE0wtHQ 172.30.233.178:5000

 docker push 172.30.233.178:5000/openshift/busybox
