Install Flux v2 with Terraform

This Terraform module is (almost) the equivalent of using the Flux CLI to install Flux v2 in to your Kubernetes cluster.

This module was mostly generated from the output of Flux CLI, using the command flux install --export > flux-system.yaml. From there, the multi-doc yaml file that the Flux CLI produces was converted into individual yaml files using mogensen/kubernetes-split-yaml. Finally the yaml files were converted to HCL using jrhouston/tfk8s. Variables were still done by hand.

Usage

terraform {
required_version = ">=0.15.0"
required_providers {
    kubernetes-alpha = {
      source  = "hashicorp/kubernetes-alpha"
      version = ">=0.3.0"
    }
  }
}

provider "kubernetes-alpha" {
  config_path = "~/.kube/config"
}

module "flux_install" {
  source = "github.com/redeux/terraform-kubernetes-flux-install"
}

TODO

--components strings list of components, accepts comma-separated values (default [source-controller,kustomize-controller,helm-controller,notification-controller])

Variables implemented, but not conditionals

--image-pull-secret string Kubernetes secret name used for pulling the toolkit images from a private registry

--network-policy deny ingress access to the toolkit controllers from other namespaces using network policies (default true)

--toleration-keys strings list of toleration keys used to schedule the components pods onto nodes with matching taints
