…ystem (#294) ## Summary Introduces the Playground Apps Manager - a web-based system for creating, managing, and deploying custom devcontainer-based applications with real-time monitoring and build log streaming. ## Overview The Playground Apps Manager provides a self-service interface for users to create and manage containerized applications using devcontainer configurations. Apps are built with the devcontainer CLI and run as isolated containers with reverse-proxy routing through Caddy. ## Key Features ### App Management - **Web UI**: Full-featured interface for CRUD operations on apps - **Dynamic Routing**: Automatic Caddy configuration for reverse-proxy routing to each app - **Container Lifecycle**: Start, stop, and monitor container status - **Real-time Status**: Live updates for app and container states ### Build System - **Devcontainer-based**: Uses devcontainer CLI for building and starting containers - **Live Build Logs**: Real-time streaming of build output to playground logs - **Platform Support**: Builds as `linux/amd64` for maximum compatibility - **Async Building**: Apps build in background with status tracking ### Optional Features Built-in support for common feature sets: - **Workbench CLI** (`wb`): Java 17, AWS CLI, gcloud CLI, startup scripts (~4 min build) - **Workbench Tools** (`workbench-tools`): Bioinformatics toolkit including bcftools, bedtools, plink, plink2, samtools, VEP, REGENIE (~8 min build) Features are automatically installed during devcontainer build with proper configuration. ### Example Apps Quick-start templates for common use cases: - **ttyd**: Web-based terminal access - **JupyterLab**: Interactive notebook environment ### Monitoring & Debugging - **Container Logs**: View logs for individual app containers - **Playground Logs**: System-level logs for build processes - **Auto-refresh**: Toggle auto-refresh (3s interval) for real-time log monitoring - **Smart Scrolling**: Maintains scroll position during log updates <img width="1494" height="465" alt="image" src="https://github.com/user-attachments/assets/5e990bee-f995-4f7e-a1fc-82072154230e" /> <img width="822" height="1114" alt="image" src="https://github.com/user-attachments/assets/32929fcf-eb27-4a21-96f6-bacb3cb1cf97" /> <img width="822" height="780" alt="image" src="https://github.com/user-attachments/assets/28dc93bc-2913-4080-9fd0-d6b6e8c45713" /> 🤖 Generated with Claude Code
