Set up NFS server

Set up on Ubuntu Link and make sure to grant NFS Share Access to your Kubernetes cluster.

Create a Configmap with nfs server properties

kind: ConfigMap
apiVersion: v1
metadata:
  name: mount-config
  namespace: azureml
data:
  mounts.yaml: |
    mountPoints:
    - mountPath: /nfs_share
      mountType: nfs
      name: nfs-name
      path: /path/to/shared-folder
      server: nfs-server.domain-name.com

Apply the Configmap

kubectl apply -f mount-config.yaml

Documentation on Specific Fields

  • mountPath: defines the path that the NFS volume will be mounted into inside your job
  • mountType: must be nfs
  • name: arbitrary symbolic name for your mount. If you define multiple mounts then this must be unique per mount
  • path: path (on the server) to the folder you want to mount
  • server: NFS server address

Multiple NFS mounts may be defined under mountPoints

The rest of the mount-config.yaml file must be exactly as above

How AML will use the mount for jobs

All jobs will look for the 'mount-config' ConfigMap. If this ConfigMap is missing or malformed then no mounts will be applied.
