Practical Homelab: Self-Hosting, CI/CD, and Automation You Can Actually Run

If you want to stop paying for a cloud CI/CD toy and instead ship code from a homelab you actually own, you’re not alone. I run a small but intentionally resilient stack at home that keeps my personal projects honest: Git hosting, a CI runner, an object store, a little monitoring, and a sane backup story. This isn’t a “cloud-killer” manifesto; it’s a pragmatic, opinionated blueprint for something you can actually install, keep stable, and incrementally grow.

Hook: the trap most hobbyists fall into is chasing the perfect architecture before they have a reliable base. You don’t need Kubernetes-sized complexity to learn DevOps discipline; you need a repeatable workflow and proven defaults you won’t outgrow in a weekend. Below is a playbook I’ve refined over years of upgrading hardware, fighting flaky networks, and learning the hard lesson that backups beat fancy features every time.

1) Start with a simple, solid foundation

• Hardware and virtualization: a modest server (or two) is enough. I run on a Proxmox VE host with 16–32 GB of RAM and 1–2 TB of fast storage for VMs and containers. The goal is not peak throughput but predictable boot, upgrade, and backup behavior. If you’re starting, a single machine with 8–16 GB RAM and a couple of disks will do; plan for growth.
• Virtualization vs containers: use virtualization for isolation and recoverability, but leverage containers for day-to-day services. A small KVM-based VM for the cluster manager or CI controller and several docker-compose services on a single host is a sane compromise. If you want Kubernetes later, you can migrate to a lightweight cluster (K3s) without starting from scratch.
• Networking basics: a stable internal DNS, predictable hostnames, and a plan for TLS. I use a home DNS (often Cloudflare with a dynamic DNS alias) and a reverse proxy fronting services. This reduces entropy and gives you a clean boundary for auth, routing, and TLS.

2) The lean stack I actually run (and you can copy)

Key components:

• Ingress and TLS: Traefik (or Nginx) as a reverse proxy with Let’s Encrypt certificates.
• Git hosting: an on-prem solution like Gitea (or Forgejo if you prefer a fork; both are lightweight and self-contained).
• CI/CD: Drone CI (server + runner) or a similar lightweight self-hosted CI. Drone is compact and pairs well with Gitea, with simple secrets management and a clean plugin ecosystem.
• Object storage: MinIO (S3-compatible) for artifacts, backups, and general storage needs.
• Observability (optional but worth it): Prometheus + Grafana + Node Exporter for basic visibility; you can start with Promtail if you want logs.
• Backup: Restic or BorgBackup to keep local clients or a dedicated backup target. I favor Restic for its simplicity and broad filesystem support.

A practical minimal topology:
