Thank you for updating this @mahdikhashan!
Should we do the same for the Training Operator v1.9 ?

[andreyvelich]

Does GHCR support additional paths so we can distinguish images by Kubeflow Project name:

docker pull ghcr.io/kubeflow/trainer/trainer-controller-manager

Thank you for this.
Could we check if uploading time does does not exceed 10min?

https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry

For example images (mostly releae-1.9 branch), I'm wondering if we take 10 or more time to upload images.
