Reverse Proxy (Caddy)

Caddyfile unter /root/Caddyfile:

git.pp1l.de {
    reverse_proxy localhost:3000
}

ci.pp1l.de {
    reverse_proxy localhost:8000
}

# Rust Service
rust.pp1l.de {
    reverse_proxy localhost:3010
}

# Fallback für localhost-Zugriff
localhost:80 {
    redir / /3000
}

• Domains:
  • git.pp1l.de → Gitea (localhost:3000)
  • ci.pp1l.de → Woodpecker Web (localhost:8000)
  • rust.pp1l.de → Rust Service (localhost:3010)

CI/CD

• Gitea: Container mit Host-Networking, persistentes Volume gitea-data
• Woodpecker Server/Agent: Host-Networking, Daten in woodpecker-server-data
• Konfiguration:
  • Server Env: /etc/woodpecker/server.env (enthält OAuth Client/Secret – nicht im Repo)
  • Agent Env: /etc/woodpecker/agent.env
• Wrapper-Skript: /root/cicd-wrapper.sh
  • Befehle: start|stop|restart|status|logs|enable|disable|monitoring {start|stop|status|logs|urls}

Monitoring

• Verzeichnis: /root/monitoring
• Startskript: start-monitoring-podman.sh
• Standard-Ports:
  • Prometheus: 9090
  • Grafana: 3002 (admin/admin123 – bitte ändern)
  • cAdvisor: 8081
  • Node Exporter: 9100
  • Alertmanager: 9093

Applikationen

• Snake Game (/root/snake-game)
  • Node.js App, Pipeline via .woodpecker.yml
  • Remote:

origin	http://automation:changeme@localhost:3000/pp1l/snake-game-cicd.git (fetch)
origin	http://automation:changeme@localhost:3000/pp1l/snake-game-cicd.git (push)

• OS Upgrade Automation (/root/os-upgrade-automation)
  • Ansible Projekt, CI konfiguriert
  • Remote:

origin	http://automation:changeme@localhost:3000/pp1l/os-upgrade-automation.git (fetch)
origin	http://automation:changeme@localhost:3000/pp1l/os-upgrade-automation.git (push)

• Rust Service (/root/rust-server)
  • Containerfile, exposed über Caddy rust.pp1l.de
  • Inhalte (Top-Level):
    • Cargo.toml
    • Containerfile
    • src

Sicherheit & Secrets

• Secrets liegen unter /root/secrets und in Env-Dateien unter /etc/woodpecker/ (Dateirechte restriktiv)
• Git-Creds für lokalen Automationsnutzer in ~/.git-credentials (nur lokale Nutzung)
• OAuth für Woodpecker in Gitea konfiguriert (Details nicht offengelegt)

Betrieb

• CI/CD Stack steuern:

/root/cicd-wrapper.sh status
/root/cicd-wrapper.sh restart

• Monitoring steuern:

/root/cicd-wrapper.sh monitoring start
/root/cicd-wrapper.sh monitoring status

Hinweise

• Host-Networking wird bewusst genutzt, um Reverse-Proxy/Port-Zugriff zu vereinfachen
• Persistente Volumes: gitea-data, woodpecker-server-data
• Bitte Standard-Passwörter zeitnah ändern und Secrets über sops/age oder Vault verwalten
