nomad-csi

Nomad CSI storage for i80.dk — democratic-csi + NFS on int.i80.dk.

Architecture

• NFS server: int.i80.dk exports /opt/csi-volumes to 192.168.15.0/24
• CSI driver: democratic-csi v1.9.0
• Plugin ID: org.democratic-csi.nfs

Deploy

# One-time: deploy CSI controller + node plugin
nomad job run csi/controller.nomad
nomad job run csi/node.nomad

# Verify
nomad plugin status org.democratic-csi.nfs

Create a volume

# Edit csi/volumes/example.hcl with your id/name/size, then:
nomad volume create csi/volumes/my-volume.hcl

# Volumes are persistent — only deleted explicitly:
nomad volume delete my-volume-id

Use in a job

volume "data" {
  type            = "csi"
  source          = "my-volume-id"
  access_mode     = "single-node-writer"
  attachment_mode = "file-system"
}

# ...in the task:
volume_mount {
  volume      = "data"
  destination = "/data"
}

Expanding to all workers

When ready, update csi/node.nomad:

• Change type = "service" → type = "system"
• Remove the constraint block

Workers need nfs-common installed (via Ansible storage.yml playbook).
