pvc-autoscaler-operator

The PVC Autoscaler Operator is an open-source solution designed to introduce autoscaling capabilities to Persistent Volume Claims (PVCs) within Kubernetes ecosystems. It accomplishes this by deploying a disk healthcheck sidecar injection mechanism, eliminating the dependence on Prometheus metrics. This progressive approach enhances the scalability and efficiency of containerized storage management.

Not extensively tested, use at your own risk.

Motivation

Current solutions of PVC autoscaling are to use Prometheus metrics to monitor the disk usage of the PVC. However, this approach is not scalable and efficient. The Prometheus metrics are collected by the Prometheus server, which is a single point of failure. The Prometheus server is also a bottleneck for the scalability of the PVC autoscaling. The Prometheus server is not designed to hand large amount of metric data. This project aims to provide a scalable and efficient solution to PVC autoscaling by introducing a disk healthcheck sidecar injection mechanism.

Acknowledgement

The initial idea for this project was inspired by how strangelove-ventures/cosmos-operator manages and scales PVC resources for cosmoshub nodes. Some of the code was also borrowed from strangelove-ventures/cosmos-operator such as internal/healthcheck and internal/controllers/pvcscaling_controller.go.
