Permission error with config file in kubernetes

[hashfunc]

Description

In Linux systems, file permissions are typically represented using 3 digits, but in some cases they can be represented with 6 digits. For example, when injecting secrets as file in a Kubernetes, permissions are represented using 6 digits.

When secret are mounted as file in kubernetes, 6-digit mode are used (e.g., 100600 instead of 0600).
As a result, attempts to change permissions but fails.
