What do you think about Rancher Longhorn distributed block storage solution?

harobed commented 7 years ago

Hi,

I didn't see Rancher Longhorn in Distributed block storage solution list. Do you think that Longhorn can be an alternative to portworx?

Best regards, Stéphane

Portworx works well enough for the time being, but it is proprietary software. Any potential alternative should match the following criteria besides being reliable:

Dynamic volume provisioning using a PersistentVolumeClaim
Deployment as a DaemonSet (no configuration/scripts outside of the manifest)
Painless operations (preferably running within a single pod)
Open source or a proprietary solution better than the current one

Longhorn could indeed be an alternative if they integrate better with Kubernetes.

I'm currently evaluating Rook, means it's running on my cluster for a couple of weeks. So far so good! Discussions going on here: https://github.com/hobby-kube/manifests/pull/1

As soon as I find the time, I'm most likely going to update the guide to recommend using Rook. Mostly because it's an open source solution, offers straight forward setup and seems pretty robust.
