Issue/Introduction

Uploading images to local registry fails with below exception:

Error during callback
com.github.dockerjava.api.exception.InternalServerErrorException: Status 500: {"errorDetail":{"message":"writing manifest: uploading manifest 24.04.02.2 to <your-registry>/dxi/dxi-dxi-installerbase: blob upload invalid"},"error":"writing manifest: uploading manifest 24.04.02.2 to <your-registry>/dxi/dxi-dxi-installerbase: blob upload invalid"}

        at java.base/java.lang.Thread.run(Thread.java:840)
Application run failed

From below output it looks like there are no issues with the image. There are 4 installerbase images with tag "24.04.02.2" and the same ID one loaded from the tar file and 3 tagged to different registries.

Environment

• Openshift
• DX Platform 24.x
• NEXUS Docker repository manager

Cause

For DX Platform Installer requires that the registry allows pushing the same image with the same tag more than once (registry must be able to check that all layers are the same and nothing needs to be done). 

 

 

 

Resolution

Set a flag on NEXUS to ALLOWS re pushing.
