🚨 The "Invisible" Security Hole in Your Docker Setup We've all heard it: "Don't commit .env files to Git." So you .gitignore them, pat yourself on the back, and move on. But here's the uncomfortable truth — your secrets are still exposed. They're sitting in plain text on your server's disk, and more embarrassingly, they're baked right into your container's metadata. Don't believe me? Try this on any Docker host you have access to: There they are. DB passwords, Stripe keys, API tokens — readable by anyone with basic Docker access. No hacking required. That’s why I rebuilt Docker Secret Operator (DSO). 🚀 DSO v3.2: Local-First, Cloud-Optional The original DSO was designed for production environments — AWS, Vault, that sort of thing. But v3.2 is different. It's built for every developer, including you on your laptop right now. The headline feature: "Zero-Cloud" Local Mode.No AWS account.No root access.No background daemon. Just a clean, secure way to handle secrets locally. 🔄 The "Before & After"Most setups today: What happens under the hood: ☁️ Production Mode: Fully Real Now If you're running production workloads, Cloud Mode is now fully implemented (not stubs anymore): 🩺 The Doctor Command (No More Guessing)When something feels off: 📦 Zero-Dependency Setup No Go. No build. No friction. Done. No .env file. No plaintext secrets. 🔗 LinksGitHub: https://github.com/docker-secret-operator/dso
