Migrate test images to docker

[cmainas]

Since, urunc has been accepted from Docker in DSOS, we should start migrating the test images to dockerhub. THis will also help us decrease the issues we have in e2e testing where pulling images takes a lot of time and leading in some cases to failures.

Hi @cmainas, I'd like to pick this up!

I've audited the codebase and found consistent usage of harbor.nbfc.io/nubificus/urunc/ in tests/e2e/test_cases.go (referencing hello-*, redis-*, nginx-* images), as well as references in kind_test.yml and the Makefile.

Proposed Plan:

1. Image Migration Script: I will write a script to pull these images from Harbor and push them to Docker Hub.
2. Codebase Update: I will verify and update all references in a single PR.

Question:
What is the target Docker Hub organization/repo convention we should use? (e.g., docker.io/urunc/ or docker.io/nubificus/?)

Hello @cheese-cakee ,

thank you for your interest in this but for security reasons only the maintainers have access to the respective dockerhub.

Thanks @cmainas, I completely understand.

In that case, could I assist by handling the codebase side of the migration?

1.I can provide a checklist here of all the specific images currently used in the tests that need to be pushed to Docker Hub.

2.Once the maintainers push the images, I can follow up with a PR that updates all the references in test_cases.go, kind_test.yml, and the Makefile to point to the new Docker Hub locations.

is that alright?

We are in the process of automating the building process of test images, so we are not gonna reuse the existing ones but replace them with new ones. I think this issue should be done by one of the maintainers.
