n8n
What it is
n8n is the self-hosted workflow automation platform running as a Docker container in the PBS infrastructure stack. It serves as the central automation hub connecting external services (Gmail, Google Drive, Instagram, YouTube, Cloudflare, Supabase) with internal systems (WordPress, pbs-hub, the Obsidian vault, OB1). n8n handles event-driven pipelines, scheduled jobs, webhook receivers, and multi-step data flows that would otherwise require custom code.
Current state
Active. Current and planned automation workflows include:
- Email-to-vault pipeline — Gmail → n8n → Gitea → Obsidian vault (session note ingestion)
- Cloudflare cache warming — Daily sitemap crawl + Cloudflare cache purge triggers
- Instagram automation — Reel detection webhook, content hub sync
- OB1 parallel write — n8n writes to both wiki-vault and OB1 simultaneously (planned)
- WordPress log monitoring — Log event alerts via n8n
- SSH login alerting — journald tailer → n8n → Google Chat
- YouTube analytics — YouTube API → n8n → Streamlit pipeline (planned)
- PBS SEO automation — Google Search Console data → Claude API → meta generation
Where it lives
- PBS Linode Docker stack, behind Traefik ingress
- Accessible via Traefik routing (internal + possibly tunneled)
- Persistent data in Docker volume
