VAST on Cloud Tools

VAST on Cloud, voctool, is a small set of tools used by terraform to manage VAST On Cloud (VOC) resources.

It focuses on secure operations and supports AWS, GCP, and Azure via their official cloud SDKs and CLIs.

Installation (from GitHub Releases)

• Download the binary:

  • Go to the GitHub repository Releases page for voctool.
  • Download the asset that matches your operating system and CPU architecture (for example: Linux amd64, macOS arm64, etc.).

• Install on macOS / Linux (adjust the filename as needed):

chmod +x voctool

# Verify
voctool --version

• Install on Windows:
  • Download the Windows binary from the Release assets.
  • Rename it to voctool.exe if needed.
  • Place it in a directory on your PATH (for example, C:\Users\<you>\bin) and open a new terminal.
  • Run:

voctool --version

Usage

Basic usage pattern:

voctool [command] [flags]

If you run voctool with no arguments, it prints help and a command tree.

Commands

• cluster-cleanup

  Clean up cluster-related resources leftover after the VoC cluster was destroyed using terraform

  voctool cluster-cleanup --cluster-name <name> --cloud-provider <provider> [flags]

  • Supported providers:

    • AWS
    • GCP
    • Azure

  • Examples:

    • GCP (cleans up matching routes in the given project):

    voctool cluster-cleanup \
      --cluster-name my-cluster \
      --cloud-provider GCP \
      --project-id my-gcp-project

    • AWS (currently a no-op, reserved for future use):

    voctool cluster-cleanup \
      --cluster-name my-cluster \
      --cloud-provider AWS

    • Azure (currently a no-op, reserved for future use):

    voctool cluster-cleanup \
      --cluster-name my-cluster \
      --cloud-provider Azure \
      --subscription-id my-subscription-id

  • Flags:

    • --cluster-name (string, required): Cluster name or UID to clean up.
    • --cloud-provider (string, required): One of AWS, GCP, or Azure.
    • --project-id (string, required for GCP): GCP project ID.
    • --subscription-id (string, required for Azure): Azure subscription ID.

Global Flags

These flags are available for all commands:

• --verbose, -v: Enable verbose output.
• --version: Show the voctool version.

Authentication

voctool uses the official cloud SDKs and CLIs to authenticate. When a command requires access to a cloud provider:

• The tool automatically detects if you are authenticated.
• If authentication is missing or expired, voctool will:
  • Explain what authentication command needs to run (such as a gcloud, aws, or az login flow).
  • Ask for your explicit consent before running anything on your behalf.
• After authentication completes, the command re-validates access before changing any resources.

You do not need to manage credentials directly; just ensure the respective cloud CLIs are installed and available on your PATH.
