Tool Terminal

Problem

Tool instances (code-server, jupyter-notebook, etc.) run in Docker containers but users have no way to access a shell inside those containers. This limits debugging, running ad-hoc commands, and managing the container environment.

Solution

Provide browser-based terminal access to running tool containers via WebSocket:

WebSocket terminal sessions - Real-time bidirectional communication
Pseudo-TTY - Full terminal emulation with proper shell behavior
xterm.js frontend - Professional terminal UI in the browser
Session management - Multiple independent terminals per instance
Access control - Only instance owners can access terminals

Key Features

Terminal Access

Open terminal from any running tool instance
Full bash/zsh shell inside the container
Standard terminal features (colors, cursor, history, etc.)

Real-time I/O

Instant character-by-character streaming
Stdout/stderr combined output
Support for interactive programs (vim, nano, etc.)

Terminal Resize

Dynamic column/row adjustment
Window resize handled gracefully
Proper text wrapping and scrolling

Session Management

Multiple terminals per instance
Independent sessions with isolation
Cleanup on disconnect

Benefits

Debug containers - Inspect running processes, check logs
Run commands - Execute ad-hoc scripts or tools
Manage environment - Install packages, edit config files
No SSH needed - Browser-based access from anywhere

Success Criteria

Terminal opens for any running instance
Commands execute and display output in real-time
Terminal resizes with browser window
Multiple terminals work independently
Sessions clean up on disconnect
Unauthorized users cannot access terminals
