kube-rclone

Introduction

kube-rclone is a rclone mount solution for Kubernetes. It allows you to sync files and directories to and from different cloud storage providers i.e Google Drive. It creates a Daemonset across the Kubernetes cluster which mounts a volume on the hostPath that can be used with other services such as kube-plex

Prerequisites

  • rclone config that has the cloud storage drive defined

This can be created by running rclone config which will take you through an interactive configuration session to generate the rclone.conf file.

Setup

The setup guide will help you get rclone running as a Daemonset on Kubernetes.

  1. Add the contents of the rclone.conf file into files/rclone.conf
  2. Deploy the kube-rclone chart with the correct remote and path defined from the rclone.conf file
> helm install ./kube-rclone --name rclone \
    --namespace rclone \
    --set rclone.remote=[insert remote to mount here] \
    --set rclone.path=[insert mount path for remote] \
    --set rclone.readOnly=true

This will deploy a Daemonset across the Kubernetes cluster that will run rclone with the mounted remote i.e Google Drive on the hostPath of the node which can be used with other services.

Additional arguments can be set to customise rclone mount depending on the Kubernetes node resources. Some additional arguments have been commented out which are based on several user set-ups. They can be used based on user preference. Mount options can be found here

Example of pod logs:

Constraints

It has only been tested with kube-plex so far. There's still more work to be done to make it stable for other services e.g Radarr and Sonarr.
