Introduction

Validates whether you have configured the image pull policy to always download the container image. Otherwise, you may end up with different versions running in your Kubernetes cluster if one node has cached a container image.

Supported Advice States

Action Needed

Automatically discovers whether all Kubernetes containers' imagePullPolicy are set to Always (explicitly configured or implicitly as the default policy for some container image versioning schemes). The discovery is performed by the open-source library kube-score and integrated into this advice.

Validation Needed

Not supported.

Implemented

Once the Kubernetes container's specification imagePullPolicy uses the Alwaysstrategy.
