TL;DR Install n8n with Docker for self-hosted workflow automation. Quick test: docker run -it --rm -p 5678:5678 n8nio/n8n. Production requires Docker Compose with persistent volumes. For updating existing deployments, see How to Update n8n Docker Container. A production-ready setup requires a docker-compose.yml file that defines persistent storage, sets N8N_EDITOR_BASE_URL for external access, and configures encryption keys. The self-hosted version is free and open-source, giving you full control over data and unlimited workflow executions. You can integrate AI capabilities through dedicated nodes like AI Agent and AI Chain, which connect to OpenAI, Anthropic, or local LLM endpoints. ...

TL;DR This guide covers updating existing n8n Docker deployments. For initial installation, see How to Install n8n with Docker for AI Workflow Automation. Updating n8n Docker containers delivers security patches, new AI nodes, and API integration fixes. The core process: pull latest image, backup data, stop container, restart with new version. Total downtime: 2-5 minutes. ...

TL;DR Running n8n with Docker Compose gives you a production-ready automation platform for AI workflows without managing complex dependencies. This guide walks through setting up n8n with persistent storage, environment configuration, and AI integrations using OpenAI, Anthropic, and local LLMs. Docker Compose handles multi-container orchestration, making it straightforward to add PostgreSQL for workflow history, Redis for queue management, and reverse proxies for SSL termination. The setup takes under 10 minutes and provides a stable foundation for building AI-powered workflows that process documents, generate content, and orchestrate multi-step automations. ...

TL;DR n8n offers two deployment paths: self-hosted (free and open-source) or cloud-hosted with tiered pricing. Self-hosted n8n runs on your infrastructure with no licensing fees, while n8n Cloud provides managed hosting across Starter, Pro, and Enterprise tiers with varying execution limits and features. Self-hosted deployments require server management but give you complete control over data, unlimited workflow executions, and no per-execution costs. Install with npm install -g n8n or run via Docker on port 5678. You handle updates, backups, SSL certificates, and scaling. Infrastructure costs depend on your hosting provider and workflow complexity – a basic VPS can run simple workflows, while high-volume automation may need dedicated servers or Kubernetes clusters. ...

TL;DR Migrating Docker workloads from macOS (Apple Silicon/ARM64) development machines to Linux (x86_64) production servers requires translating platform-specific paths, architecture-dependent images, and development shortcuts into production-ready configurations. macOS developers often rely on Docker Desktop features, /Users/... volume paths, and ARM64-native images that break silently on Linux hosts. AI tools like Claude can parse Docker Compose files and Dockerfiles to flag architecture mismatches, translate volume paths, and generate multi-platform build configs. Feed your existing configurations to the API and get back an annotated migration plan. ...
