Terraform Provider Crusoe

This repo defines the official Terraform Provider for use with Crusoe Cloud, the world's first carbon-reducing, low-cost GPU cloud platform.

Getting Started

To get started, first install Terraform. Then, get an access keypair from https://console.crusoecloud.com/security/tokens and add the following to ~/.crusoe/config:

[default]
access_key_id="MY_ACCESS_KEY"
secret_key="MY_SECRET_KEY"

Then, add the following to the start of your terraform file, for example main.tf:

terraform {
  required_providers {
    crusoe = {
      source = "registry.terraform.io/crusoecloud/crusoe"
    }
  }
}

locals {
  # replace with path to your SSH key if different
  ssh_key = file("~/.ssh/id_ed25519.pub")
}

You can then use Terraform to create instances, disks, and networking rules. To create 10 VMs with 8 80GB A100s, we would add the following block:

# Create 10, 8xA100-80GB VMs
resource "crusoe_compute_instance" "nodes" {
  count = 10
  name = "node-${count.index}"
  type = "a100-80gb.8x"
  ssh_key = local.ssh_key
}

For more usage examples, including storage disks, startup scripts, and firewall rules, see the examples folder.

Development

To develop the Terraform provider, you'll need a recent version of golang installed.

Add the following to your ~/.terraformrc

provider_installation {

  dev_overrides {
    "registry.terraform.io/crusoecloud/crusoe" = "/Users/{MY_USERNAME_HERE}/go/bin/"
  }

  # For all other providers, install them directly from their origin provider
  # registries as normal. If you omit this, Terraform will _only_ use
  # the dev_overrides block, and so no other providers will be available.
  direct {}
}

Run make install to build a provider and install it into your go-path. Then, you should be able to run terraform apply with the provided examples.

Versioning

A new version of the Crusoe Cloud Terraform provider is generated when there is a new merge request into the release branch in GitHub. This generates a new tag and triggers our goreleaser pipeline which will handle distributing the new Terraform version.

Our main branch is primarily used for development. Once features are ready to be deployed, a Crusoe Cloud maintainer will merge the changes from main into release to deploy a new version.

Contributing

We welcome (and have already had several!) open-source contributions to the Crusoe Cloud Terraform Provider. Here is the workflow for contributing to the Crusoe Cloud Terraform provider:

Make a branch off main and open a pull request from your branch into main.
A Crusoe Cloud maintainer will review the pull request and, once approved, merge it into the main branch.
Once your pull request has been approved, make a separate pull request to add your changes to the changelog into the main branch. There will be an (Unreleased) version that you can add your changes to.
To release your changes, you can make a separate pull request from the main branch into the release branch. Merges into the release branch trigger our goreleaser job which handles distributing a new version.
Once the pull request has been approved and merged by a Crusoe Cloud maintainer, a new Terraform version will be released.
A separate pull request will be made by a Crusoe Cloud maintainer to update the changelog with the date the newest version has been released.
