In this blog post, Ahmet Alp Balkan explains the peculiar and undocumented behavior of file changes in Kubernetes Secret and ConfigMap volumes when using the inotify(7) syscall. He highlights that typical file watch events like IN_MODIFY or IN_CLOSE_WRITE don't occur for files in these volumes. Instead, only the IN_DELETE_SELF event is received, requiring code to handle re-establishing the monitor each time a file is updated.

Balkan discusses the resilient file reloads from disk and the AtomicWriter algorithm used by kubelet for atomic and consistent updates to Secret/ConfigMap volumes. He explains the file structure in a mounted Secret/ConfigMap volume and the reason behind receiving only the IN_DELETE_SELF event.

To handle this behavior, Balkan suggests mounting ConfigMaps/Secrets as directories, starting inotify watches on individual files, avoiding the use of IN_DONT_FOLLOW option, handling inotify deletion events, re-establishing inotify watches when receiving deletion events, and testing the file reloading logic on Kubernetes. He also mentions opening an issue to document this behavior in the official Kubernetes documentation.
