Description

Any secrets stored in environment variables could be exposed if the environment is logged or otherwise exposed by an application. Providing access to secrets via volume mounts is preferred.

How to fix?

Ensure spec.containers.env.valueFrom attribute of pod doesn't contain secretKeyRef.

Example Configuration

apiVersion: v1
kind: Pod
metadata:
  name: valud-pod
spec:
  containers:
    - name: mysql
      image: mysql:8.0

          mountPath: "/etc//mysql/credentials"
