Execute code snippets in isolated containers.
https://www.reddit.com/r/programming/comments/1l9ptba/execute_code_snippets_in_isolated_containers/
<!-- SC_OFF -->I wanted to share a project I've been working on called Taylored Snippets Web. It's an Angular-based web application that lets you create, manage, and run code snippets in a worksheet-style interface. The main goal was to create a secure and isolated environment for code execution for each user. Key Features Isolated Execution: The application has two distinct modes that can be launched using Docker Compose profiles: Multitenant Mode: This is the core feature. It uses a Node.js orchestrator service to spin up a dedicated, isolated Docker container for each user session. This ensures that one user's code can't interfere with another's. Singletenant Mode: A simpler mode for local development that uses a single, shared runner instance for all users. Broad Language Support: The runner can execute code in a wide variety of languages using shebangs, including python3, node, bash, java, ruby, php, and more. Snippet Management: Users can add both text snippets (for annotations) and compute snippets (for executable code) to a worksheet. These can be reordered on the page via drag-and-drop. Live Output: Standard output and errors from code execution are displayed directly in the UI. Tech Stack Frontend: Built with modern Angular using standalone components, zoneless change detection, and Angular Material for the UI. Backend: A Node.js/Express Orchestrator that uses dockerode to manage the lifecycle of runner containers. A Node.js Runner that executes code snippets and communicates results. Communication: Real-time communication between the frontend and the runner is handled with Socket.IO. Deployment: The entire stack is defined in a docker-compose.yml file, making it easy to launch with either the multitenant or singletenant profile. I've put a lot of work into the architecture and would love to hear your thoughts or answer any questions about the implementation. The repo has all the source code, including the CI workflow and Docker setup. <!-- SC_ON --> submitted by /u/sasizza (https://www.reddit.com/user/sasizza)
