I am new to kubernetes. I have Rest Api running in a pod through which we are uploading a file and storing that on pod's local pvc. I want to create a new pod in my kubernetes cluster whenever new file is uploaded in persistence storage PVC. Any guidance how to achieve this?

  • Could you add some more context to this question. If you have a PVC already then it is attached to some k8s object , the application running in the pod of that object must trigger a new pod on addition of new file , is that what you are expecting. Also how are files being uploaded to PVC. Are you on any cloud ? – Tarun Khosla May 18 '22 at 06:32

If I understand correctly, I think you can monitor files created on the host where they are stored and then invoke the kubernetes API to create the pod. See the links below for pod creation.

  • you can use inotify to watch files from filesystem. https://pkg.go.dev/k8s.io/utils/inotify. for the python version see also https://pypi.org/project/inotify/ – zilex May 18 '22 at 07:38
