tf-aks-fluxcd

Tired of boostrapping Flux by hand?
No CI/CD process to have that all setup?
Not feeling like you want to run all those commands to perform your installation?

There is a solution:

Terraform code to bootstrap Flux on AKS from your repository. This will use your ~/.kube/config file and the current context to know where to perform the installation. And boostrap your GitOps repository to the desired location

Pre-requisites

Azure Kubernetes cluster already created
Your kubectl context to be set to the cluster that you want to deploy.

Setup

# Add your configuration to config.auto.tfvars, this will be automatically picked up by Terraform

branch          = "dev"                             # Branch for bootstraping
github_owner    = "julanu"                          # Repository owner
target_path     = "clusters/my-cluster"             # Relative path to your Flux files
repository_name = "gitops-kustomize-infrastructure" # Repository name

Install

$ terraform init && terraform validate
$ terraform plan
$ terraform apply -var "github_token=<YOUR_TOKEN" -auto-approve
