Openhift online: Error in StartContainer - ErrImagePull: "unauthorized: Authentication required"

I am new to openshift and I have showstopper:

On my computer, I created a Dockerimage called restservice

and I tested it successfully:

docker run -d -p 8080:8080 restservice

Then I created an application in Openshift-Online with an image:

oc new-app restservice

I can see that the deployer module starts up and after failure creates a working module.

from

oc describe pod restservice-2-50n0h

I am getting the following error:

...

I have no idea what authentication needs.

An invalid step is to pop the image to go online.

So these are the Steps:



  • Create image on local computer

    docker build -t restservice .

  • Tag it with registry / username / image

    docker tag restservice registry.starter-us-west2.openshift.com/myusername/myrestservice

  • Get your Openshift Registry Login Secret

    oc whoami -t sr3grwkegr3kjrk42k2jrg34kb5k43g5k4jg53

    (sr3 ... - output)

  • Enter the Openshift Registry directory

    docker login -u name@mail.com -p sr3grwkegr3kjrk42k2jrg34kb5k43g5k4jg53 https://registry.starter-us-west-2.openshift.com

  • Push the image into the registry

    docker push registry.starter-us-west-2.openshift.com/myusername/myrestservice

  • Create a new app with an image

    oc new-app myrestservice

That's all....
