This project is a collection of Terraform modules that sets up a GitOps infrastructure on a local Kubernetes cluster using Kind and Flux, integrated with a GitHub repository. By default, we use the kubeconfig file for connectivity. However, the project can also be configured to use certificates. Modules
The project comprises the following modules:
Kind Cluster: This module sets up a local Kubernetes cluster using Kind (Kubernetes in Docker). By default, it uses a kubeconfig file for connectivity, but it can also be configured to use certificates.
module "kind_cluster" {
source = "github.com/bartaadalbert/tf-kind-cluster"
KIND_CLUSTER_NAME = var.KIND_CLUSTER_NAME
NUM_MASTERS = var.NUM_MASTERS
NUM_WORKERS = var.NUM_WORKERS
}
TLS Private Key: This module generates a TLS private key.
module "tls_private_key" {
source = "github.com/den-vasyliev/tf-hashicorp-tls-keys"
algorithm = "RSA"
}
GitHub Repository: This module sets up a GitHub repository. It uses the develop branch of the specified repository.
module "github_repository" {
source = "github.com/bartaadalbert/tf-github-repository?ref=develop"
github_owner = var.GITHUB_OWNER
github_token = var.GITHUB_TOKEN
repository_name = var.FLUX_GITHUB_REPO
public_key_openssh = module.tls_private_key.public_key_openssh
public_key_openssh_title = "flux_deploy_key"
}
Flux Bootstrap: This module bootstraps Flux (the GitOps Kubernetes operator) in your Kind cluster and connects it to your GitHub repository. By default, it uses the kubeconfig file for connectivity, but it can also be configured to use certificates.
module "flux_bootstrap" {
source = "github.com/bartaadalbert/tf-fluxcd-flux-bootstrap"
github_repository = "${var.GITHUB_OWNER}/${var.FLUX_GITHUB_REPO}"
github_token = var.GITHUB_TOKEN
private_key = module.tls_private_key.private_key_pem
config_path = module.kind_cluster.kubeconfig
}Clone this repository and navigate to its directory:
git clone https://github.com/bartaadalbert/tf-pro cd tf-pro
Initialize Terraform: terraform init
Apply the Terraform configuration: terraform apply
Remember to provide the necessary variables (GITHUB_OWNER, GITHUB_TOKEN, FLUX_GITHUB_REPO) as required.
If you want to use certificates instead of a kubeconfig file for connectivity, uncomment the relevant lines in the kind_cluster and flux_bootstrap modules. License
