kubectl ImagePullBackOff due to secret - kubernetes

Question

I'm creating kubevirt in minikube, initially kubevirt-operator.yaml fails with ImagePullBackOff. After I added secret in the yaml
imagePullSecrets:
- name: regcred
containers:
all my virt-operator* started to run. virt-api* pods still shows ImagePullBackOff.
The error comes out as
Events:

Manually, I can pull the same image with docker login. Any help would be much appreciated. Thanks

Answer 1

This docker image looks like it is in a private registry(and from oracle). And I assume the regcred is not correct. Can you login there with docker login? if so you can create regcred secret like this
$ kubectl create secret docker-registry regcred --docker-server=<region-key>.ocir.io --docker-username='<tenancy-namespace>/<oci-username>' --docker-password='<oci-auth-token>' --docker-email='<email-address>'
Also check this oracle tutorial: https://www.oracle.com/webfolder/technetwork/tutorials/obe/oci/oke-and-registry/index.html

Answer 2

Here you can find the steps to implement secret values to the cluster.
If you are using a private registry, check that your secret exists and the secret is correct. Your secret should also be in the same namespace.
Your Minikube is a VM not your localhost. You try this
Open Terminal
eval $(minikube docker-env)
docker build .
kubectl create -f deployment.yaml
just valid this terminal. if closed terminal again open terminal and write eval $(minikube docker-env)
eval $(minikube docker-env) this code build image in Minikube
Also, try to login docker on all nodes by using docker login.
There is also a lengthy blog post describing how to debug image pull back-off in depth here

Hey if you look here. I think you can find some helpful documentation.
What they are doing is, they are upload the dockerconfig file which has login credentials as a secret and then referring to that in the deployment.
You could try to follow these steps and do something similar. Let me know if it works
