Automated Docker Database Backups on Raspberry Pi: An Orchestration Guide using Backrest, Restic, and Rclone
Running databases on a home lab Raspberry Pi is fine — until the SD card dies and you realize you had no consistent backups. This guide walks through a production-grade backup pipeline using Backrest, Restic, and Rclone, with pre-backup hooks that dump PostgreSQL and MongoDB before the snapshot even starts.
yt-dlp-console: An Interactive CLI So You Never Memorize Flags Again
Every time I needed to download a video with yt-dlp, I’d end up Googling the same flags. So I built yt-dlp-console — an interactive terminal wrapper that guides you through the whole process without memorizing a single flag.
React Error Boundaries: Handling Rendering Errors Gracefully
Your React app showed a blank white screen — here is how to prevent it. Walk through rendering vs. runtime errors, class-based Error Boundary implementation, and the react-error-boundary library with practical code examples.
How to Install a Private Docker Registry on Raspberry Pi with Portainer (Home Network)
Run your own private Docker image registry on a Raspberry Pi using Portainer. This guide uses HTTP only (no TLS) with basic auth enabled. You will deploy the registry and a web UI via a Portainer Stack, configure clients to allow an insecure registry, and verify everything works on your home network. Note: A registry is the server (e.g., registry:2). Repositories are image collections inside the registry. TL;DR Image: registry:2 Runs on LAN over HTTP: :5000 (no TLS) UI: joxit/docker-registry-ui:latest on :5001 Auth: htpasswd basic auth Persist storage: bind mount /var/lib/registry Clients: add 192.168.1.100:5000 to Docker insecure-registries Prerequisites Raspberry Pi 4/5 (ARM64 preferred) Raspberry Pi OS 64‑bit or another 64‑bit Linux Docker and Portainer CE installed on Raspberry Pi A stable hostname or IP (e.g., 192.168.1.100) Check architecture: ...
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). What is n8n? n8n is an open‑source, self‑hostable workflow automation tool. You build automations by connecting nodes in a visual editor: Triggers like webhooks, schedules/cron, IMAP, polling start a workflow; you transform data, branch logic, handle errors, and call services/APIs or databases. ...
