Host Volumes

Dynamic Host Volumes is a simple driver built into Nomad which allocates storage from a local directory on the host. This is useful for testing and simple development environments; however, the volume will only be available on a single server.

Nomad Configuration

The location where the host volume plugin should create the volumes can be set using the host_volumes_dir parameter in client section of the nomad.hcl:

client {
  host_volumes_dir = "/srv/host_volumes"
}

By default Nomad stores them under the data_dir

Example Usage in Knot

Below is an example of how to use the dynamic host volume driver. This configuration should be added to the Volumes section of a template or as a standalone volume:

volumes:
  - name: "test-volume"
    type: "host"
    plugin_id: "mkdir"
    parameters:
      mode: "0755"
      uid: 1000
      gid: 1000
