 ## Secure pod access to mounted volumes
 
-For your applications to run correctly, pods should run as a defined user or group and not as *root*. The 'securityContext' for a pod or container lets you define settings such as *fsGroup* to assume the appropriate permissions on the mounted volumes. 
-*fsGroup* is a field within the 'securityContext' of a Kubernetes Pod specification. It defines a supplemental group ID that Kubernetes assigns to all processes in the Pod and recursively to the files in mounted volumes. This ensures that the Pod has the correct group-level access to shared storage volumes.

-When a volume is mounted, Kubernetes changes the ownership of the volume's contents to match the *fsGroup* value. This is particularly useful when containers run as non-root users and need write access to shared volumes.

+When a volume is mounted, Kubernetes changes the ownership of the volume's contents to match the **fsGroup** value. This is particularly useful when containers run as non-root users and need write access to shared volumes.

+The following example YAML shows the **fsgroup** value:
 
+```yaml
 securityContext:
   fsGroup: 2000

 ```
-In this example:
-All files in mounted volumes are  accessible by GID 2000.
