I try to adhere to Infrastructure as Code (IaC) and GitOps practices using tools like [Terraform](https://www.terraform.io), [Kubernetes](https://kubernetes.io), [Flux](https://fluxcd.io), [Renovate](https://github.com/renovatebot/renovate) and [GitHub Actions](https://github.com/features/actions). --- ## ⛵ Kubernetes There is a template over at [onedr0p/flux-cluster-template](https://github.com/onedr0p/flux-cluster-template) if you wanted to try and follow along with some of the practices I use here. ### Installation This semi hyper-converged cluster runs [Talos Linux](https://talos.dev), an immutable and ephemeral Linux distribution built for [Kubernetes](https://kubernetes.io), deployed on bare-metal Intel NUCs. [Rook](https://rook.io) then provides my workloads with persistent block, object, and file storage; while a seperate server provides file storage for my media. 🔸 _[Click here](./kubernetes/bootstrap/talos/topf.yaml) to see my Talos configuration._ ### Core Components - [cilium](https://cilium.io): Internal Kubernetes networking plugin. - [cert-manager](https://cert-manager.io): Creates SSL certificates for services in my Kubernetes cluster. - [external-dns](https://github.com/kubernetes-sigs/external-dns): Automatically manages DNS records from my cluster in a cloud DNS provider. - [external-secrets](https://github.com/external-secrets/external-secrets) with [1Password Connect](https://github.com/1Password/connect) to inject secrets into Kubernetes. - [envoy-gateway](https://gateway.envoyproxy.io): Kubernetes Gateway API implementation using Envoy proxy. - [rook](https://rook.io): Distributed block storage for peristent storage. - [sops](https://github.com/getsops/sops): Managed secrets for Kubernetes and Terraform which are commited to Git. - [volsync](https://github.com/backube/volsync): Backup and recovery of persistent volume claims. ### GitOps [Flux](https://github.com/fluxcd/flux2) watches the clusters in my [kubernetes](./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` 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. Those Flux kustomizations will generally have a `HelmRelease` or other resources related to the application underneath it which will be applied. [Renovate](https://github.com/renovatebot/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. --- ## ☁️ Cloud Dependencies While most of my infrastructure and workloads are self-hosted I do rely upon the cloud for certain key parts of my setup. This saves me from having to worry about two things. (1) Dealing with chicken/egg scenarios and (2) services I critically need whether my cluster is online or not. The alternative solution to these two problems would be to host a Kubernetes cluster in the cloud and deploy applications like [Vaultwarden](https://github.com/dani-garcia/vaultwarden)and [Uptime Kuma](https://github.com/louislam/uptime-kuma/). However, maintaining another cluster and monitoring another group of workloads is a lot more time and effort than I am willing to put in. | Service | Use | Cost | |-------------------------------------------------|-------------------------------------------------------------------|----------------| | [Cloudflare](https://www.cloudflare.com/) | Domain and S3 | ~$30/yr | | [GitHub](https://github.com/) | Hosting this repository and continuous integration/deployments | Free | | [Fly.io](https://fly.io/) | I have two small machines running here which host my password manager and Uptime Kuma | Free (total spend is below $5) | --- ## 🔧 Hardware | Device | Count | OS Disk Size | Data Disk Size | Ram | Operating System | Purpose | |-----------------------------|-------|--------------|-----------------------------|------|------------------|---------------------| | Asus NUC14 RNUC14RVHU5 | 3 | 870 Evo 500GB SSD | 990Pro 1TB NVMe (rook-ceph) | 64GB | Talos OS | Control-plane/Workers | | Jonsbo N3 custom build | 1 | 256GB SSD | 4x18TB ZFS Mirror (tank) | 32GB | NixOS | NFS + Backup Server | | PiKVM (Arch) | 1 | - | - | - | - | Network KVM | | TESmart 8 Port KVM Switch | 1 | - | - | - | - | Network KVM (PiKVM) | | UniFi UDM-Pro-SE | 1 | - | - | - | - | Routing/Firewall/IPS/DNS | | UniFi USW-Pro-Max-24-PoE | 1 | - | - | - | - | Core Switch | | USW-Enterprise-8-PoE | 1 | - | - | - | - | Attic | | APC SMT2200RM2U w/ NIC | 1 | - | - | - | - | UPS | --- ## ⭐ Stargazers <div align="center"> [](https://star-history.com/#rust84/k8s-gitops&Date) </div> --- ## 🤝 Gratitude and Thanks Thanks to all the people who donate their time to the [Home Operations](https://discord.gg/home-operations) Discord community.
