n3t.uk k3s Testing Clusters Configuration

This repository provides a simple Terraform configuration to allow it to build a k3s-based Kubernetes cluster with Flux, hosted in GitHub, to provide GitOps for standardised configuration and service deployments, and connected with Cloudflare for DNS and ingress tunnels.

Note

This repository is not responsible for deploying the base configuration for each k3s Cluster; that is managed through the ansible repository instead. Once the Cluster is started and running, then this Terraform configuration will deploy standard ConfigMap and Secret resources, and bootstrap fluxcd on to the Cluster.

Usage

The following must be set in the environment before terraform plan and apply can be run:

$ set -x GITHUB_TOKEN xxx
$ set -x CLOUDFLARE_TOKEN xxx
$ set -x AUTH0_API_TOKEN xxx
$ gcloud auth login
...
You are now logged in as [jon@than.io].
Your current project is [project-name-here].  You can change this setting by running:
  $ gcloud config set project PROJECT_ID

$ flux create secret oci ghcr-auth \
    --url=ghcr.io \
    --username={github-user} \
    --password={github-pat}
► oci secret 'ghcr-auth' created in 'flux-system' namespace
