Description Alay Patel 2020-09-22 01:40:27 UTC

Description of problem:
Imagestreamtags pointing to external tags or alias should not be migration during a staged image migration. 



Version-Release number of selected component (if applicable):
MTC 1.3.0


How reproducible:
Always

Steps to Reproduce:
1. Create a source namespace with multiple imagestreams and imagestreamtags point to with external source
2. Create a stage migration from source to destination
3. Check the imagestreamtags point to external source on destination

Actual results:
Imagestreamtags found in the destination that points to external source

Expected results:
Only imagestream tags that are internal to the cluster should be migrated during stage. The tags pointing to external source or aliases are kube resources that should be migrated during final migration.

Verified using MTC 1.3

In order to verify it we run
OCP-34867 - Imagestreams Stage
OCP-34872 - Imagestream Stage Nopvc
OCP-34875 - Imagestream Stage Skipimagestreams

External images (not stored in the internal regitry) are not staged, as expected.

Moved to VERIFIED status.
