Go was the obvious choice because:</p> <ul> <li> <strong>Single Binary:</strong> Easy deployment without worrying about dependencies.</li> <li> <strong>Concurrency:</strong> Handling multiple WebSocket streams for live logs is a breeze with Goroutines.</li> <li> <strong>Low Footprint:</strong> It runs perfectly even on the smallest Raspberry Pi or a $5 VPS.</li> </ul> <h2> 🛠️ Key Features (Alpha v0.1.2) </h2> <p>Blackwater isn't just another dashboard; it's a real-time management engine:</p> <ul> <li> <strong>Real-Time Metrics ($O(1)$ Broadcasting):</strong> I built a custom WebSocket Hub. It fetches system stats once and broadcasts them to all connected clients, ensuring minimal CPU overhead.</li> <li> <strong>Docker Integration:</strong> Using the official Docker SDK for Go, you can inspect, start/stop containers, and stream <strong>live container logs</strong> directly.</li> <li> <strong>Multi-Distro Firewall:</strong> Native support for both <code>UFW</code> and <code>Firewalld</code>. No matter your Linux distro, Blackwater has your back.</li> <li> <strong>Process Ownership Tracking:</strong> It doesn't just list processes; it tracks who started what, making it great for shared environments.</li> </ul> <h2> 🏗️ The Tech Stack </h2> <ul> <li> <strong>Backend:</strong> Go 1.24 + Gin Gonic</li> <li> <strong>Database:</strong> MySQL + GORM</li> <li> <strong>Auth:</strong> JWT-based RBAC (Role-Based Access Control)</li> <li> <strong>Real-time:</strong> WebSockets (Custom Hub Architecture)</li> </ul> <h2> 🚧 It's Open Source! (Seeking Feedback) </h2> <p>Blackwater is currently in its early Alpha stage. I'm looking for fellow Gophers and DevOps enthusiasts to:</p> <ol> <li> Review the <strong>Command Sanitization</strong> logic for security.</li> <li> Suggest improvements for the <strong>WebSocket Hub</strong> scaling.</li> <li> Contribute to the upcoming Web UI.</li> </ol> <h3> 🔗 Check out the Repo </h3> <p>I’d love to get your feedback (and maybe a ⭐️ if you like the concept!):</p> <p><strong>GitHub:</strong> <a href="https://github.com/Ahmedfargh/black-water-server-manager" rel="noopener noreferrer">https://github.com/Ahmedfargh/black-water-server-manager</a></p> <h2> What's Next? </h2> <p>I’m currently working on a <strong>Docker Compose UI</strong> and an automated <strong>Security Alert System</strong> that notifies the admin via email when a new login is detected.</p> <p><strong>Happy Coding!</strong></p> go linux devops kernal
