[fsvalim]

The containerSecurityContext from Helm Chart Loki is not being defined according to the default values.yaml into the StatefulSet resource.

Steps to reproduce the behavior:

1. Execute the helm install dry-run and check the output.

Expected behavior: allowPrivilegeEscalation: false in the containerSecurityContext, should be defined because is set as default. value

• Infrastructure: Kubernetes
• Deployment tool: helm

Part of the dry-run output:
