How to reference Internal Registry?

[alininja]

Hi,

I want to build from images another build that has been stored to the integrated registry:

OpenShift Enterprise 3.0 | Architecture | Infrastructure Components | Image Registry

Is this possible?  Right now I pull the IP and port from the build log and use that in the subsequent Dockerfile's FROM directive, like:

FROM 123.456.789.123:5000/myproject/myapp-dev:latest

Is there a default name that the integrated registry uses?  Or is there a better way to build off of previously built images using the integrated registry?

Thank you in advance for you

In CDK we do expose local registry which openshift create to consume it. registry is exposed to "hub.openshift.rhel-cdk.10.1.2.2.xip.io" provided you didn't change IP before starting CDK box.

Please refer to https://lalatendu.org/2016/06/09/using-the-docker-registry-in-openshift-using-adb/  post which we did for Atomic Developer Bundle (which is upstream to CDK). hope that would solve your issue,

Thanks kumarpraveen.nitdgp, I'll give that a try once I resolve this problem: Is it possible to free disk space if using somebody else's Openshift instance?

Thanks and take care!

Hey kumarpraveen.nitdgp, your suggestion didn't work for me.  But I found a way around my issue.

I used the build config settings to override the FROM directive to force the build process to use the image from the image stream within the openshift infrastructure:

- apiVersion: v1

  kind: BuildConfig

  spec:

    strategy:

      type: Docker

      dockerStrategy:

        from:

          kind: "ImageStreamTag"

          name: "myapp-dev:latest"

Thanks again for your help!
