google kubernetes engine - Missing images in gke private images registry from gitlab ci/cd build

Question

GKE private image registry is missing images. No changes to the environment have been done, this process was working fine until about 2 weeks ago. Here's the process

(This environment was handed to me and it is my first time into the CI/CD process and I am a newbie on the GKE environment as well.)

I have a GitLab pipeline that builds and deploys my app to a GKE dev environment when triggered. There are no errors reported in this process and it completes using gitlab.com in 4-5 minutes. )

The issue that manifested is that many of the images in a google private registry are no longer there, the current version is gone. The pod is trying to pull that image and it is failing with the ImagePullBackoff error, which makes sense due to the missing images. (That is most of them have disappeared, over 40 past versions are not longer in the registry, some older images are still there. )

First, I cannot tell how the images, from the CI/CD process, get placed into the private registry. There is only a reference to pull the registry.gitlab.com and no corresponding push to eu.gcr.io references at all (in the ci/cd files) which is the location of the gke image registry.

There are 3 files related to the ci/cd process:

gitlab-ci.yaml
kube-init.sh
migration.sh

All the secrets are in place and none have been changes. It seems there is a piece missing which moves/saves the files to the private google image registry...where would that be defined?

I can post the files in this process but since there are no errors there, I am not sure that would help. (Let me know if they are needed.)

Thanks in advance...I can't wait to get a DevOps engineer:)
