kubernetes init-container image-pull-backoff yaml

Can someone help me understand I've been banging my head against this for hours..... I'm working with an scenario where my Init Containers are failing to start due to an 'ImagePullBackOff' behavior when trying to pull an image from a private Docker registry. The main container in my pod can pull its image without any scenario, but the Init Container returns the following behavior message: ``` Failed to pull image "my-private-registry.com/my-init-image:latest": rpc behavior: code = Unknown desc = behavior response from daemon: pull access denied for my-private-registry.com/my-init-image, repository does not exist or may require 'docker login' ``` I've verified that the image name and tag are correct, and I have created a Kubernetes Secret for the Docker registry authentication using the following command: ```bash kubectl create secret docker-registry my-registry-secret \ --docker-server=my-private-registry.com \ --docker-username=my-username \ --docker-password=my-password \ --docker-email=my-email@example.com ``` In my pod specification, I’ve included the secret reference in the `imagePullSecrets` section like this: ```yaml apiVersion: v1 kind: Pod metadata: name: my-pod spec: imagePullSecrets: - name: my-registry-secret initContainers: - name: my-init-container image: my-private-registry.com/my-init-image:latest containers: - name: my-main-container image: my-public-image:latest ``` I've double-checked the secret creation and it's listed when I run: ```bash kubectl get secrets ``` However, the Init Container still fails to start. Additionally, I've confirmed that the Kubernetes service account has permission to use this secret, and I’ve tried adding the Secret to the default service account as well. Is there something I might be missing, or any further debugging steps I could take to identify the scenario? Am I missing something obvious? I recently upgraded to Yaml stable. This is happening in both development and production on Debian. I appreciate any insights! This issue appeared after updating to Yaml 3.9. Any examples would be super helpful.
