This is a mono repository for my home infrastructure and Kubernetes cluster. I try to adhere to Infrastructure as Code (IaC) and GitOps practices using tools like Ansible, Terraform, Kubernetes, Flux, Renovate, and GitHub Actions.
My Kubernetes cluster is deployed with Talos. This is a semi-hyper-converged cluster, workloads and block storage are sharing the same available resources on my nodes while I have a separate server with ZFS for NFS/SMB shares, bulk file storage and backups.
This repo is based on onedr0p's cluster template, so go check that out if you want to try and follow along with some of the practices I use here.
- actions-runner-controller: Self-hosted Github runners.
- cert-manager: Creates SSL certificates for services in my cluster.
- cilium: eBPF-based networking for my workloads.
- cloudflared: Enables Cloudflare secure access to my routes.
- external-dns: Automatically syncs ingress DNS records to a DNS provider.
- external-secrets: Managed Kubernetes secrets using 1Password Connect.
- sops: Managed secrets for Kubernetes and Terraform which are commited to Git.
- spegel: Stateless cluster local OCI registry mirror.
Flux watches the clusters in my kubernetes folder (see Directories below) and makes the changes to my clusters based on the state of my Git repository.
The way Flux works for me here is it will recursively search the kubernetes/apps folder until it finds the most top level kustomization.yaml per directory and then apply all the resources listed in it. That aforementioned kustomization.yaml will generally only have a namespace resource and one or many Flux kustomizations (ks.yaml). Under the control of those Flux kustomizations there will be a HelmRelease or other resources related to the application which will be applied.
Renovate watches my entire repository looking for dependency updates, when they are found a PR is automatically created. When some PRs are merged Flux applies the changes to my cluster.
This Git repository contains the following directories under Kubernetes.
📁 kubernetes
├── 📁 apps # applications
├── 📁 components # re-useable kustomize components
└── 📁 flux # flux system configurationThis is (will be) a high-level look at how Flux deploys my applications with dependencies.
