Mount GCP Filestore (NFS) – Valohai Help

This feature is available for customers who are using their own cloud or on-premises workers.

Mounting gives you direct access to the network file system like GCP Filestore, without having to download the files on your machine.

Valohai does not version or keep track of the changes made inside the mounted file system. The files that are created, edited, or deleted will not be versioned as part of a Valohai execution.

NFS mounts are not version controlled

We strongly recommend using the Valohai inputs and outputs system, as they are versioned as a part of the execution.

You can mount a filesystem to access a large dataset, run preprocessing operations, and output the processed dataset into Valohai Outputs before it’s used further in the pipeline. This way the snapshot of the preprocessed data will be versioned.

Define a mount in YAML

You can either use an existing or create a new GCP Filestore.

Create your Filestore in the same VPC where all Valohai resources are in or set up VPC peering between the two VPCs

Example valohai.yaml configuration:

- step:
    name: mount-sample
    image: python:3.7
    command:
        - ls -la /my-data
    mounts:
        - destination: /my-data
          source: <IP>:/mystore
          type: nfs
          readonly: false

Mounts are defined for each environment separately. Contact Valohai, if you see an error mounts were ignored due to environment configuration. in your execution logs.
