Last week, when that same discussion popped up, "schmichael" (who works on Nomad I understand) said "Nomad supports CSI like Kubernetes. Unfortunately many CSI storage providers assume kubernetes or adhere to kubernetes behavior even when it deviates from the spec, so there are gotchas."

That makes be a bit wary to use it because I would like my cloud storage to be reliable.
- sofixa 4y agoYep, some CSI providers do that, but as far as i know it's more niche ones (like VMware's), not any of the big cloud providers.
- candiddevmike 4y agoI tried using a CSI driver with Nomad (AWS) and AFAIK you have to pre-create the EBS volumes? I couldn't figure out how to spin them up on demand.
- sofixa 4y agoThat was probably before the Nomad 1.3 release which added a bunch of new CSI features, including dynamic volume creation IIRC.
- orthoxerox 4y agoI wouldn't call vmware a niche provider, they own a large share of on prem virualization market.
- sofixa 4y agoWhich is a dying breed, and furthermore running an orchestrator on top of another one (Nomad or Kubernetes on top of vSphere) is a terrible anti-pattern that wastes CPU and makes performance issues hard to debug due to the two layers.
