Startup and restarts are script-driven rather than supervised by an init system. +- Autogenerated Dockerfile: The effective devcontainer Dockerfile is generated on demand by `.devcontainer/scripts/generate-dockerfile.sh`. It combines the root `Dockerfile` (with certain COPY instructions removed) and an extra "devcontainer" stage from `.devcontainer/resources/devcontainer-Dockerfile`. When you change the resource Dockerfile, re-run the generator to refresh `.devcontainer/Dockerfile`. +- Where to put setup: Prefer baking setup into `.devcontainer/resources/devcontainer-Dockerfile`. Use `.devcontainer/scripts/setup.sh` only for steps that must happen at container start (e.g., cleaning up nginx/php ownership, creating directories, touching runtime files) or depend on runtime paths. + +Debugging (F5) +The Frontend and backend run in debug mode always. You can attach your debugger at any time. +- Python Backend Debug: Attach - The backend runs with a debugger on port 5678.

This can be [Docker Desktop](https://www.docker.com/products/docker-desktop/) or Docker Engine installed via other methods (like the official [get-docker script](https://get.docker.com)). + * [Visual Studio Code](https://code.visualstudio.com/) installed. + * The [VS Code Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) installed. + +2. **Launch the Devcontainer:** + * Clone this repository. + * Open the repository folder in VS Code. + * A notification will pop up in the bottom-right corner asking to **"Reopen in Container"**. Click it. + * VS Code will now build the Docker image and connect your editor to the container. Your terminal, debugger, and all tools will now be running inside this isolated environment. + +#### Key Workflows & Features + +Once you're inside the container, everything is set up for you. + +**1. Services (Frontend & Backend)** +![Services](./img/DEV/devcontainer_1.png) + +The container's startup script (`.devcontainer/scripts/setup.sh`) automatically starts the Nginx/PHP frontend and the Python backend. You can restart them at any time using the built-in tasks. + +**2. Integrated Debugging (Just Press F5!)** +![Debugging](./img/DEV/devcontainer_2.png) + +Debugging for both the Python backend and PHP frontend is pre-configured and ready to go. + +* **Python Backend (debugpy):** The backend automatically starts with a debugger attached on port `5678`. Simply open a Python file (e.g., `server/__main__.py`), set a breakpoint, and press **F5** (or select "Python Backend Debug: Attach") to connect the debugger. +* **PHP Frontend (Xdebug):** Xdebug listens on port `9003`. In VS Code, start listening for Xdebug connections and use a browser extension (like "Xdebug helper") to start a debugging session for the web UI. + +**3. Common Tasks (F1 -> Run Task)** +![Common tasks](./img/DEV/devcontainer_3.png) + +We've created several VS Code Tasks to simplify common operations. Access them by pressing `F1` and typing "Tasks: Run Task". + +* `Generate Dockerfile`: **This is important.** The actual `.devcontainer/Dockerfile` is auto-generated. If you need to change the container environment, edit `.devcontainer/resources/devcontainer-Dockerfile` and then run this task. +* `Re-Run Startup Script`: Manually re-runs the `.devcontainer/scripts/setup.sh` script to re-link files and restart services. +* `Start Backend (Python)` / `Start Frontend (nginx and PHP-FPM)`: Manually restart the services if needed. + +**4. Running Tests** +![Running tests](./img/DEV/devcontainer_4.png) + +The environment includes `pytest`. You can run tests directly from the VS Code Test Explorer UI or by running `pytest -q` in the integrated terminal. The necessary `PYTHONPATH` is already configured so that tests can correctly import the server modules. + +### How to Maintain This Devcontainer + +The setup is designed to be easy to manage. Here are the core principles: + +* **Don't Edit `Dockerfile` Directly:** The main `.devcontainer/Dockerfile` is a combination of the project's root `Dockerfile` and a special dev-only stage. To add new tools or dependencies, **edit `.devcontainer/resources/devcontainer-Dockerfile`** and then run the `Generate Dockerfile` task. +* **Build-Time vs. Run-Time Setup:** + * For changes that can be baked into the image (like installing a new package with `apk add`), add them to the resource Dockerfile. + * For changes that must happen when the container *starts* (like creating symlinks, setting permissions, or starting services), use `.devcontainer/scripts/setup.sh`. +* **Project Conventions:** The `.github/copilot-instructions.md` file is an excellent resource to help AI and humans understand the project's architecture, conventions, and how to use existing helper functions instead of hardcoding values. + +This setup provides a powerful and consistent foundation for all current and future contributors to NetAlertX. \ No newline at end of file diff --git a/docs/DEV_ENV_SETUP.md b/docs/DEV_ENV_SETUP.md index b81b3f6a..d466e794 100755 --- a/docs/DEV_ENV_SETUP.md +++ b/docs/DEV_ENV_SETUP.md @@ -32,6 +32,9 @@ Examples: ## Development Environment Set Up +>[!TIP] +> There is also a ready to use [devcontainer](DEV_DEVCONTAINER.md) available. + The following steps will guide you to set up your environment for local development and to run a custom docker build on your system.
