groundcover Terraform Provider

Terraform provider for managing groundcover resources.

Usage Examples

Basic usage examples can be found in the examples/ directory:

• Policy Resource: examples/resources/groundcover_policy/resource.tf
  • Demonstrates how to define a groundcover_policy resource, including roles and data scope.
• ServiceAccount Resource: examples/resources/groundcover_serviceaccount/resource.tf
  • Shows how to create and manage service accounts with associated policies.
• API Key Resource: examples/resources/groundcover_apikey/resource.tf
  • Illustrates API key creation and management for service accounts.
• Monitor Resource: examples/resources/groundcover_monitor/resource.tf
  • Provides examples of configuring monitoring rules and alerts.

Local Development and Testing

To use this provider locally before it is published to the Terraform Registry, follow these steps:

1. Build the Provider: Compile the provider binary using the Makefile:

   make build
   

   This command typically places the compiled terraform-provider-groundcover executable into the ./dist directory within your project.

2. Configure Terraform CLI for Local Override: Terraform needs to know where to find your locally built provider instead of trying to download it from a registry. Create or edit the Terraform CLI configuration file (~/.terraformrc on macOS/Linux, %APPDATA%\terraform.rc on Windows) and add the following provider_installation block:

   # ~/.terraformrc or %APPDATA%\terraform.rc
   
   provider_installation {
     # Replace "groundcover/groundcover" if you used a different source 
     # address in main.go. Replace the path with the actual absolute path
     # to the directory containing the built provider binary (step 1).
     dev_overrides {
       "registry.terraform.io/groundcover/groundcover" = "/Users/<YOUR_HOME_FOLDER>/projects/terraform-provider-groundcover/dist"
       # Example for Windows:
       # "registry.terraform.io/groundcover/groundcover" = "C:/Users/<YourUser>/path/to/terraform-provider-groundcover/dist"
     }
   
     # For all other providers, install them directly from their origin registries.
     direct {}
   }
   

   • Important: Replace registry.terraform.io/groundcover/groundcover if your provider address in main.go is different.
   • Important: Replace /Users/<YOUR_HOME_FOLDER>/projects/terraform-provider-groundcover/dist with the absolute path to the directory containing the terraform-provider-groundcover binary built by make build.

3. Use in a Terraform Project: In a separate directory for your Terraform configuration:

   • Create a .tf file (e.g., main.tf).
   • Declare the provider requirement, ensuring the source matches the one used in dev_overrides:

     # main.tf
     
     terraform {
       required_providers {
         # This 'source' value MUST exactly match:
         # 1. The key used in your ~/.terraformrc dev_overrides block
         # 2. The 'Address' set in your provider's main.go
         groundcover = {
           source = "registry.terraform.io/groundcover/groundcover"
           # Version constraint is still good practice, but less critical
           # for local dev as dev_overrides takes precedence.
           # Use ">= 0.1.0" or similar if you haven't tagged releases yet.
           version = ">= 0.0.0"
         }
       }
     }
     
     # Configure the provider instance
     provider "groundcover" {
       # It's STRONGLY recommended to provide the API key via an environment variable
       # export TF_VAR_groundcover_api_key="YOUR_API_KEY_HERE"
       api_key = var.groundcover_api_key # Use this if defining a variable below
     
       # Base URL is optional, defaults to api.groundcover.com in the provider code
       api_url = "https://api.main.groundcover.com" # defaults to https://api.groundcover.com
       org_name = "groundcover"                     # your organization ID as provided in the installation
     }
     
     # (Optional but recommended) Define input variables
     variable "groundcover_api_key" {
       type        = string
       description = "groundcover API Key"
       sensitive   = true
     }
     
     # Define a policy resource using your provider
     resource "groundcover_policy" "test_policy" {
       name        = "My Terraform Test Policy"
       description = "Policy managed via local Terraform provider build"
       claim_role  = "tf-test-claim"
       role = {
         admin  = "admin" # key is "read"/"write"/"admin" - value is ignored
       }
     
       # Example data_scope (adjust based on actual API needs)
       data_scope = {
         simple = {
           operator = "and"
           conditions = [
             {
               key    = "cluster"
               origin = "root"
               type   = "string"
               filters = [
                 {
                   op    = "match"
                   value = "my-prod-cluster"
                 }
               ]
             },
             {
               key    = "namespace"
               origin = "root"
               type   = "string"
               filters = [
                 {
                   op    = "not_match"
                   value = "kube-system"
                 }
               ]
             }
           ]
         }
       }
     }
     
     output "policy_id" {
       value = groundcover_policy.test_policy.uuid
     }
     
     output "policy_revision" {
       value = groundcover_policy.test_policy.revision_number
     }
     

   • Run terraform init. Terraform will detect the dev_overrides and use your local build.

Requirements

• Terraform >= 1.0 (Check required_version if specified in main.tf)
• Go >= 1.21 (to build the provider plugin)
• groundcover Account and API Key.

Provider Reference

Configure the groundcover provider in your Terraform configuration:

provider "groundcover" {
  # api_key  = "YOUR_API_KEY" # Required
  # base_url = "https://api.your-instance.groundcover.com" # Optional
}

Arguments

• api_key (String, Required, Sensitive): Your groundcover API key. It is strongly recommended to configure this using the TF_VAR_groundcover_api_key environment variable rather than hardcoding it.
• base_url (String, Optional): The base URL for the groundcover API. Defaults to api.groundcover.com if not specified.
