Description

Images should be specified with their digests to ensure integrity. The policy checks containers and initContainers entries in the resource spec and flags any image value that does not include a digest (i.e., missing the ‘@’ separator). Specifying images by digest enforces immutability and helps ensure consistent, repeatable, and trusted deployments.

Compliant Code Examples

apiVersion: v1
kind: Pod
metadata:
  name: private-image-test-1

  containers:
    - name: uses-private-image

      imagePullPolicy: Always
      command: [ "echo", "SUCCESS" ]

Non-Compliant Code Examples

apiVersion: v1
