NFS Volumes

Volumes provide persistent NFS storage hosted on a node. They can be mounted by compute instances (Docker Swarm or Kubernetes) across the cluster.

Create a volume

nimbus volume create --name mydata --node NODE_ID --folder /exports/mydata

This sets up the NFS export on the node and makes it available for attachment.

List volumes

nimbus volume list

Attach to a compute instance

At creation time:

nimbus compute run --name app --swarm SWARM_ID \
  --image myapp --type small --volume VOL_ID:/data

To a running instance:

nimbus compute volume attach --instance INSTANCE_ID --volume VOL_ID:/data
nimbus compute volume detach --instance INSTANCE_ID --volume VOL_ID

Attach to a Kubernetes cluster

Creates a PersistentVolume and PersistentVolumeClaim backed by the NFS export:

nimbus k8s volume attach --cluster CLUSTER_ID --name VOL_ID --size 1Gi
nimbus k8s volume detach --cluster CLUSTER_ID --name VOL_ID

Delete a volume

Volumes must be detached from all resources before deletion:

nimbus volume delete VOL_ID
