Docker Web Interface — Multi-Server Container Management

Docker Web Interface is a PHP web application to administer several Docker hosts from a single dashboard: connect servers over SSH or the Docker socket, then manage containers, images and Dockerfiles.

Overview

Managing containers across several machines usually means juggling SSH sessions and CLI commands. This project centralizes it in a secure, fully containerized web control plane that talks to the Docker API of every registered server.

Features

• Servers — register remote hosts, connect through SSH or the Docker socket, and check connection status
• Containers — list running, stopped and failed containers; start, stop, restart, edit or remove them; inspect ports, volumes, environment variables and logs
• Images — list, pull and remove images on each server
• Dockerfiles — create, edit and store custom Dockerfiles centrally, then build them on any connected server
• Users — account management for the super admin, with three permission levels enforced by middleware

Architecture & engineering

• MVC architecture in PHP with Twig templates, a service layer for Docker operations, and security and logging middleware
• MariaDB persistence with hashed passwords, input validation and SQL injection protection
• Fully containerized stack (Apache, PHP, Composer and Docker-in-Docker images) with an HTTPS-only Apache configuration
• GitLab CI/CD pipeline with build, test, SAST security scanning and deployment stages
• Git workflow with feature and hotfix branches, commit conventions and merge request reviews
