TFC-Operator

TFC-Operator is the Kubenretes Native Operator with GitOPs of Terraform. Supports Github/Gitlab (Public/Private), and uses HCL (Hashicorp Configuration Language) to provision resources in Cloud Platform (e.g. AWS, Azure, GCP, vSphere.. etc)

Quick Start

This guide contains information on creating an EC2 instance on AWS through Terraform Claims (CR).

1. Public Repo

(1) Push the HCL (Hashicorp Configuration Language) code that defines Terraform resources to the git repository (Github / GitLab)

Example.

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 3.27"
    }
  }

  required_version = ">= 0.14.9"
}

provider "aws" {
  access_key = "<AWS_ACCESS_KEY_ID>"
  secret_key = "<AWS_SECRET_ACCESS_KEY>"
  region = "us-east-1"
}

resource "aws_instance" "app_server" {
  ami           = "ami-0003076ab1664cd23"
  instance_type = "t2.micro"

  tags = {
    Name = "ExampleAppServerInstance"
  }
}

(2) Create a Terraform claim based on the previously created Git Repo information

kubectl apply -f samples/public/01_claim.yaml

2. Private Repo

(1) Push the HCL (Hashicorp Configuration Language) code that defines Terraform resources to the git repository (Github / GitLab)

Example. (same as 1-(1))

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 3.27"
    }
  }

  required_version = ">= 0.14.9"
}

provider "aws" {
  access_key = "<AWS_ACCESS_KEY_ID>"
  secret_key = "<AWS_SECRET_ACCESS_KEY>"
  region = "us-east-1"
}

resource "aws_instance" "app_server" {
  ami           = "ami-0003076ab1664cd23"
  instance_type = "t2.micro"

  tags = {
    Name = "ExampleAppServerInstance"
  }
}

(2) Create a secret holding an access token that can access the private repo

kubectl apply -f samples/private/01_secret.yaml

(3) Create a Terraform claim based on the previously created Git Repo information

kubectl apply -f samples/private/02_claim.yaml
