Description

Service account 'automountServiceAccountToken' should be set to 'false'. Avoid automounting service account tokens. Service account tokens are used to authenticate requests from in-cluster processes to the Kubernetes API server. Many workloads do not need to communicate with the API server and hence should have automountServiceAccountToken set to false.

How to fix?

Set the spec.automountServiceAccountToken attribute in Podsand ServiceAccount to false.

Example Configuration

apiVersion: v1
kind: ServiceAccount
metadata:
  name: valid-sa
automountServiceAccountToken: false

---
apiVersion: v1
kind: Pod
metadata:
  name: valid-pod
spec:
  serviceAccountName: valid-sa
  automountServiceAccountToken: false
  containers:
    - image: nginx:1.21.6
      name: nginx
