s3flex

Kubernetes flexvolume driver which can mount s3 compatible storages as k8s volumes

Status

Basic functionality is implemented and it's already used in testing scenarios, production-grade testing and unittests are missing yet, so use with caution.

Deploy

fuse and curl have to be installed on the nodes. After that the flexvolume driver can be deployed using the daemonset resource:

$ kubectl create ns s3flex
$ kubectl apply -f ./s3flex-ds.yaml
