This is derivative work by Jancis which I customized for my needs. First, kudos, this is amazing work!

The major changes are the following:

• fully configurable by environment variables
• check mountpoint after rclone forks (rclone forks too fast to be available for the pod)
• allow definition of remotes on the fly (i.e. for crypt)
• helm chart provided

Issues:

• reevaluate the current CSI implementation (i.e. use staging)
• rclone goes zombie sometimes. not sure if this is a rclone or csi issue.

Usage:

• deploy helm chart to your cluster

helm repo add diseq https://diseq.github.io/helm-charts
helm repo update
helm install csi-rclone diseq/csi-rclone --create-namespace --namespace csi-rclone

• create a PVC and PV

------ snip, old readme for reference ------

This project implements Container Storage Interface (CSI) plugin that allows using rclone mount as storage backend. Rclone mount points and parameters can be configured using Secret or PersistentVolume volumeAttibutes.

Works:

• 1.13.x

Does not work:

• v1.12.7-gke.10, driver name csi-rclone not found in the list of registered CSI drivers

TLDR: kubectl apply -f deploy/kubernetes --username=admin --password=123

1. Set up storage backend. You can use Minio, Amazon S3 compatible cloud storage service.

2. Configure defaults by pushing secret to kube-system namespace. This is optional if you will always define volumeAttributes in PersistentVolume.

apiVersion: v1
kind: Secret
metadata:
  name: rclone-secret
type: Opaque
stringData:
  remote: "s3"
  remotePath: "projectname"
  s3-provider: "Minio"
  s3-endpoint: "http://minio-release.default:9000"
  s3-access-key-id: "ACCESS_KEY_ID"
  s3-secret-access-key: "SECRET_ACCESS_KEY"

Deploy example secret

kubectl apply -f example/kubernetes/rclone-secret-example.yaml --namespace kube-system

3. You can override configuration via PersistentStorage resource definition. Leave volumeAttributes empty if you don't want to. Keys in volumeAttributes will be merged with predefined parameters.

apiVersion: v1
kind: PersistentVolume
metadata:
  name: data-rclone-example
  labels:
    name: data-rclone-example
spec:
  accessModes:
  - ReadWriteMany
  capacity:
    storage: 10Gi
  storageClassName: rclone
  csi:
    driver: csi-rclone
    volumeHandle: data-id
    volumeAttributes:
      remote: "s3"
      remotePath: "projectname/pvname"
      s3-provider: "Minio"
      s3-endpoint: "http://minio-release.default:9000"
      s3-access-key-id: "ACCESS_KEY_ID"
      s3-secret-access-key: "SECRET_ACCESS_KEY"

Deploy example definition

kubectl apply -f example/kubernetes/nginx-example.yaml

Current code is referencing projects repository on github.com. If you fork the repository, you have to change go includes in several places (use search and replace).

1. First push the changed code to remote. The build will use paths from pkg/ directory.

2. Build the plugin

make plugin

3. Build the container and inject the plugin into it.

make container

4. Change docker.io account in Makefile and use make push to push the image to remote.

make push
