Docker Tutorial Web Application

The Docker Tutorial Web Application is an interactive leawrning platform designed to teach users how to write and execute Dockerfiles effectively. This platform allows users to write Dockerfiles, build images, and run containers in a real execution environment.

By leveraging Svelte for the frontend, NestJS for the API server, and Go with the Docker Engine API for execution, the application ensures an intuitive and responsive experience while maintaining security and efficiency. The Go-based execution engine runs the submitted Dockerfiles inside a controlled Docker environment, verifying the correctness of user-submitted configurations without requiring manual intervention.

With an interactive code editor, instant feedback, and secure sandboxed execution, this tutorial provides a hand-on learning experience that bridges the gap between theory and practical application.

    User->>Svelte (Frontend): Writes a Dockerfile in editor
    Svelte (Frontend)->>NestJS (API Server): Submits Dockerfile via API
    NestJS (API Server)->>Go (Docker Runner): Sends Dockerfile for execution
    Go (Docker Runner)->>Docker Engine: Builds and runs the Dockerfile
    Docker Engine-->>Go (Docker Runner): Returns build and run output
    Go (Docker Runner)-->>NestJS (API Server): Sends validation result
    NestJS (API Server)-->>Svelte (Frontend): Returns result (success/fail)
    Svelte (Frontend)-->>User: Displays output and feedback
