Rahti image registry instructions to Noppe guide for teachers?

[samumantha]

Didn't this exist before? If so, why was it removed?

Something along the lines of (might be outdated, and will need a bit more info to be on docs):

• Add Rahti to CSC project, accept terms
• Create Rahti project and link to CSC project (link to Rahti page here)
• Get token for new registry https://console-openshift-console.apps.2.rahti.csc.fi/k8s/cluster/projects from under your name > Copy login command (needs oc installed)
• Give access to anonymous and unauthenticated: oc policy add-role-to-user registry-viewer system:anonymous -n AND
  oc policy add-role-to-user registry-viewer system:unauthenticated -n
• Login to new registry docker login -u g -p $(oc whoami -t) image-registry.apps.2.rahti.csc.fi
• Tag image: docker tag imagename image-registry.apps.2.rahti.csc.fi//:
• Push image docker push image-registry.apps.2.rahti.csc.fi//:
• Use that same link in Noppe application
