How to push docker images to openshift internal registry and create application from it

Assuming you have the OCP (openshift container platform) cluster ready and the user has image push permissions on a namespace (ex:- dev)

TL;DR

  • Grab the Cluster IP Address of internal docker registry
  • tag the local image to internal docker registry
  • grab the auth token and login to inter docker registry
  • push the tagged image to internal registry

Grab the cluster ip address provided for openshift internal registry

  • oc get svc -n default | grep registry #172.30.43.173

Create a new project to test

  • oc new-project test

Tag your local image to remote reg

  • docker tag localimage 172.30.43.173:5000/test/localimage #WTmRhkFBQS9WD1PzzUDpp_JPygROAOMZa8R67j586P8

login to internal docker reg

  • docker login -p WTmRhkFBQS9WD1PzzUDpp_JPygROAOMZa8R67j586P8 -e unused -u unused 172.30.43.173:5000

Push image to internal registry

  • docker push 172.30.43.173:5000/test/localimage
