The DevOps Stack You Own: Why Self-Hosting Matters

You're tired of SaaS bills creeping up every month. Your team grows, your CI/CD pipelines get more complex, and suddenly your $50/month DevOps budget is $500. Worse—you don't control your data, your latency, or your uptime. There's another way.

Self-hosting your DevOps stack with open source tools gives you sovereignty, zero licensing costs, and the ability to customize everything. Here's how to build a production-grade stack that rivals GitHub Actions, GitLab, or CircleCI—without the vendor lock-in.

The Core: Your Git Server

Everything starts with source control. Gitea is the lightweight champion here—written in Go, runs on a Raspberry Pi, and feels identical to GitHub in day-to-day use. Unlike GitLab (which demands 4GB RAM minimum), Gitea hums along on 512MB.

docker run -d --name=gitea -p 3000:3000 -v gitea-data:/data gitea/gitea:latest

That's it. You've got pull requests, issue tracking, webhooks, and CI/CD integration in under a minute.

CI/CD Without the Noise

Woodpecker CI integrates natively with Gitea. It's what Drone CI would have been if it stayed open source. Pipelines are defined in .woodpecker.yml files right in your repos, and it runs containers on your own hardware.

pipeline:
  test:
    image: python:3.12
    commands:
      - pip install -r requirements.txt
      - pytest
  build:
    image: docker
    commands:
      - docker build -t myapp:$CI_COMMIT_TAG .
    when:
      event: tag

No plugins marketplace to navigate. No secret pricing tiers. Just YAML and containers.

Artifact Storage with an Edge

MinIO is your S3-compatible object store. Put your Docker images, build artifacts, and database backups here. It's API-compatible with AWS S3, so your existing tools (boto3, s3cmd) work unmodified.

Run it alongside your CI to keep artifacts local—your builds stay fast because they don't cross the public internet.

Monitoring That Doesn't Lie

Grafana + Prometheus is the industry standard, and self-hosting it means you control retention, alerting rules, and dashboards. Hook it into your CI pipeline to track build times, failure rates, and deployment frequency.

docker-compose -f monitoring/docker-compose.yml up -d

You get real-time graphs of your DevOps health. No per-dashboard pricing.

Putting It Together

A minimal stack that covers 90% of teams:

• Gitea → Source control
• Woodpecker CI → Build/test/deploy
• MinIO → Object storage
• Prometheus + Grafana → Monitoring
• Nginx → Reverse proxy with Let's Encrypt SSL

All of it fits in under 4GB RAM on a single $10/month VPS. Scale by adding worker nodes when you need more build capacity.

Why This Matters

The biggest lie in DevOps is that you need enterprise tools to do enterprise work. You don't. You need a Git server, a CI runner, storage, and monitoring. Self-hosting these core pieces removes the friction of vendor negotiations, data transfer fees, and API rate limits.

Your team commits code. Your CI runs tests. Your artifacts get stored. All on hardware you control.

That's the stack that never sends you a surprise invoice.
