How to Self-Host n8n on Raspberry Pi 4 (ARM64) with Docker Compose
This guide shows a clean, reliable way to run n8n on a Raspberry Pi 4 using Docker Compose. Note: I want to use this setup primarily for AI workflows (transcription, summarization, RAG, content drafting). TL;DR / Quick start Check architecture (arm64 preferred): uname -m # aarch64 -> 64-bit, armv7l -> 32-bit Create docker-compose.yml using the snippet below. Set WEBHOOK_URL, GENERIC_TIMEZONE, and TZ for your locale. Start: docker compose up -d Open: http://raspi.local:5678 (or your Pi’s IP) Logs: docker compose logs -f n8n — Stop: docker compose stop What is n8n? n8n is an open‑source, self‑hostable workflow automation tool. You build automations by connecting nodes in a visual editor: triggers (webhooks, schedules/cron, IMAP, polling) start a workflow; you transform data, branch logic, handle errors, and call services/APIs or databases. It’s ideal for glue code and recurring tasks without writing and deploying full apps. ...
