info:
|
|
name: Image Pull Policy set to Always
|
|
author: princechaddha
|
|
severity: low
|
|
description: Ensures that Kubernetes deployments have the image pull policy set to 'Always', which guarantees the most up-to-date version of the image is used.
|
|
impact: |
|
|
Not setting the image pull policy to 'Always' may cause pods to use outdated versions of images, which can lead to security vulnerabilities if the images contain fixes or updates.
|
|
remediation: Update the image pull policy in Kubernetes Deployments to 'Always' to ensure that the latest container images are always used.
