AKS has an issue pulling a container image from the ACR

Question

I have an issue with the AKS, Kubernetes cannot pull the image from the ACR, It show the message "unauthorized: authentication required" I already set permissions on the ACR to the AKS Service Principal. It had worked fine until today when I proced to update the pod with a new container from the ACR.

Answer 1

The SP already has authorization to pull images from the ACR.

I followed the post here and now the AKS is able to pull images from ACR. When I created the AKS its SP didn't have secrets nor certificates setted, but it had working fine since 12 months ago, suddenly AKS now needs to have a secret in its SP to authenticate over the ACR.

Thanks...
