vcluster Terraform Provider

Custom Terraform provider that talks to a vcluster API and calls /createcluster to create clusters.

Build

cd /home/behrooz/Projects/vcluster_terraform
go build -o terraform-provider-vcluster

Install locally for Terraform

Terraform expects the provider binary in a specific directory based on <hostname>/<namespace>/<type>/<version>/<os>_<arch>.

For a local provider with:

• source: local/vcluster/vcluster
• version: 0.1

Copy the binary like this (Linux amd64 example):

mkdir -p ~/.terraform.d/plugins/local/vcluster/vcluster/0.1/linux_amd64
cp terraform-provider-vcluster ~/.terraform.d/plugins/local/vcluster/vcluster/0.1/linux_amd64/

Adjust the OS/arch folder name if necessary.

Example Terraform configuration

Create a new directory for using the provider, e.g. example/ and add main.tf:

terraform {
  required_providers {
    vcluster = {
      source  = "local/vcluster/vcluster"
      version = "0.1"
    }
  }
}

provider "vcluster" {
  base_url = "http://localhost:8082"

  # Credentials used for POST /login. The provider will automatically
  # call /login, get the token from {"token": "..."} and send it as
  # the Authorization header on subsequent API calls.
  username = "admin"
  password = "admin"
}

resource "vcluster_cluster" "example" {
  name             = "mytiny"
  cluster_id       = "2qjqhhqr"
  control_plane    = "k8s"
  status           = "Progressing"
  cpu              = "1"
  memory           = "1024"
  platform_version = "v1.31.6"
  health_check     = ""
  alert            = ""
  endpoint         = ""
  cluster_type     = "tiny"
  coredns_cpu      = "0.1"
  coredns_memory   = "0.25Gi"
  apiserver_cpu    = "0.1"
  apiserver_memory = "0.25Gi"
}

Then run:

cd example
terraform init
terraform apply
