Confusion Over Open Ports in VS Code Dev Containers
A developer running a .NET dev container in VS Code sees the app port opened by Code.exe on the host rather than Docker, and docker port shows nothing. They are unsure how port forwarding works.

Similar Problems
surfaced semanticallyNo macOS Devcontainer Support for GPU Passthrough in VS Code
Developers using macOS cannot run local AI models with GPU acceleration inside VS Code devcontainers because Docker on Mac lacks GPU passthrough. Windows has CUDA forwarding but no equivalent exists for Apple Silicon, forcing developers to choose between isolation and performance.
Dynamic Docker container URL not accessible after spin-up
Developers building code-generation platforms that spin up ephemeral Docker containers cannot easily retrieve the localhost URL where the running application is accessible. Docker only returns the container ID on start, requiring additional inspection steps that break automated preview workflows. This is a friction point for anyone building vibe-coding or sandbox environments.
Unreliable Local WebSocket Forwarding via Smee Client
A developer running a Dockerized service on WSL2 cannot reliably forward webhook/websocket traffic from a remote server to their local machine using smee-client, hitting ECONNREFUSED errors despite the tunnel showing activity. Sparse documentation for smee-specific error scenarios makes debugging local tunnel forwarding difficult for developers.
VS Code Cannot Attach Multiple Windows to One Running Dev Container
Developers using git worktrees inside a single Docker dev container find that VS Code Dev Containers will not let them open a second or third window attached to the same running container; attempts either refocus the existing window or prompt for a new configuration. This blocks parallel development across multiple worktrees sharing one container.
MCP servers silently fail to load in VS Code Continue with Dockerized Ollama
Developers configuring an MCP server alongside the Continue VS Code extension running Ollama in Docker on WSL2 see no MCP tools in chat and no surfaced spawn errors. Diagnosing whether the failure is in stdio spawn, container networking, or extension wiring is opaque.
