Integrate Terraform with Tiger Cloud

Terraform is an infrastructure-as-code tool that enables you to safely and predictably provision and manage infrastructure.

This page explains how to configure Terraform to manage your Tiger Cloud service or self-hosted TimescaleDB.

Prerequisites

To follow the procedure on this page you need to:

• Create a target Tiger Cloud service.

  This procedure also works for self-hosted TimescaleDB.

• Download and install Terraform.

Configure Terraform

Configure Terraform based on your deployment type:

Tiger Cloud

You use the Tiger Data Terraform provider to manage Tiger Cloud services:

1. Generate client credentials

2. Configure Tiger Data Terraform provider

   1. Create a main.tf configuration file with at least the following content. Change x.y.z to the latest version of the provider.

      terraform {
        required_providers {
          timescale = {
            source  = "timescale/timescale"
            version = "x.y.z"
          }
        }
      }
      
      # Authenticate using client credentials generated in Tiger Cloud Console.
      # When required, these credentials will change to a short-lived JWT to do the calls.
      provider "timescale" {
       project_id = var.ts_project_id
       access_key = var.ts_access_key
       secret_key = var.ts_secret_key
      }
      
      variable "ts_project_id" {
       type = string
      }
      
      variable "ts_access_key" {
       type = string
      }
      
      variable "ts_secret_key" {
       type = string
      }

   2. Create a terraform.tfvars file in the same directory as your main.tf to pass in the variable values:

      export TF_VAR_ts_project_id="<your-timescale-project-id>"
      export TF_VAR_ts_access_key="<your-timescale-access-key>"
      export TF_VAR_ts_secret_key="<your-timescale-secret-key>"

3. Add your resources

   Add your Tiger Cloud services or VPC connections to the main.tf configuration file. For example:

   resource "timescale_service" "test" {
     name              = "test-service"
     milli_cpu         = 500
     memory_gb         = 2
     region_code       = "us-east-1"
     enable_ha_replica = false
   
     timeouts = {
       create = "30m"
     }
   }
   
   resource "timescale_vpc" "vpc" {
     cidr         = "10.10.0.0/16"
     name         = "test-vpc"
     region_code  = "us-east-1"
   }

You can now manage your resources with Terraform. See more about available resources and data sources.

Self-hosted TimescaleDB

You use the cyrilgdn/postgresql PostgreSQL provider to connect to your self-hosted TimescaleDB instance.

Create a main.tf configuration file with the following content, using your connection details:

   terraform {
    required_providers {
     postgresql = {
      source  = "cyrilgdn/postgresql"
      version = ">= 1.15.0"
     }
    }
   }

   provider "postgresql" {
    host            = "your-timescaledb-host"
    port            = "your-timescaledb-port"
    database        = "your-database-name"
    username        = "your-username"
    password        = "your-password"
    sslmode         = "require" # Or "disable" if SSL isn't enabled
   }

You can now manage your database with Terraform.
