cluster setup with talos

Setup Directory Structure

The /setup directory contains all the components needed to bootstrap the Kubernetes cluster:

/setup/bootstrap

Contains Helmfile configurations for initial cluster bootstrapping:

  • helmfile.d/00-crds.yaml - Extracts CRDs from Helm charts before Flux starts (uses postRenderer to automatically filter CRDs)
  • helmfile.d/01-apps.yaml - Core apps (Cilium CNI, CoreDNS, cert-manager, Flux)

/setup/flux

Flux GitOps configuration files which are the entrypoint for flux operating the cluster from this repo. It also contains all of the shared OCIRepository and HelmRepository definitions used by various HelmReleases in the cluster. It is necessary to ensure that the Helm repositories are available before the HelmReleases are applied.

/setup/talos

Talos Linux configuration for all cluster nodes. See talos/ for details on the nodes and talos configuration

talos setup & bootstrapping

(run from the repo root)

Use talhelper to generate the config files in the clusterconfig directory.

task talos:generate-clusterconfig

Bootstrap the talos nodes. It may take some time for the cluster to be ready.

task k8s-bootstrap:talos

kubernetes setup & bootstrapping

Bootstrap the kubernetes cluster with required prerequisites (cilium CNI, CRDs, flux, etc).

task k8s-bootstrap:apps
