Nebius NFS Module

This Terraform module provisions an NFS server on Nebius Cloud. It creates a virtual machine with a secondary disk attached, formats the disk, and sets up an NFS server that exports the disk as an NFS share.

Module Structure

The module includes the following files and directories:

• main.tf - The main Terraform configuration file for the module.
• variables.tf - Definitions of variables used within the module.
• outputs.tf - Outputs after the module has been applied.
• provider.tf - The provider configuration file (to be filled in with your provider's details).
• files/
  • cloud-config.sh - A shell script that initializes the NFS server on the virtual machine.

Configure Terraform for Nebius Cloud

• Install NCP CLI
• Add environment variables for terraform authentication in Nebuis Cloud

export YC_TOKEN=$(ncp iam create-token)

Usage

To use this module in your Terraform environment, you will need to create a Terraform configuration for example file terraform.tfvars with example conent:

folder_id = "<folder_id>" # folder where you want to create your resources
subnet_id = "<subnet_id>" # subnet_id where the VM should be created
nfs_size = "930" # must be divisible by 93
nfs_ip_range = "<internal_network>" # network address, eg 10.0.0.0/16, where you want you NFS share to be accessible
sshkey = "<ssh_key>"

Then you can mount on your target device using command

sudo apt-get install nfs-common
sudo mount <ip_address>:/nfs /nfs

To get best perfomance from the network you may change MTU to 8910. For Ubuntu 22.04 LTS:

netplan set ethernets.eth0.mtu=8910
netplan apply
