stellarshenson d9896a7073 feat: add icons to buttons and auto-refresh on stop, implement GitHub Actions CI/CD

UI Enhancements:
- Add Font Awesome icons to all control buttons (stop, start, restart, manage volumes)
- Auto-refresh page after server stop with smooth UI transitions
- Hide/show appropriate buttons based on server state (Restart vs Manage Volumes)
- Re-inject icons removed by JupyterHub's DOM manipulation

Technical Implementation:
- MutationObserver watches for JupyterHub DOM changes after stop
- Immediate UI state correction before page refresh
- Comprehensive console logging for debugging

CI/CD:
- Add GitHub Actions workflow for Dockerfile validation with hadolint
- Triggers on push to main, version tags, and pull requests
- Uses hadolint to ensure Dockerfile best practices

Raw Blame History

Release v3.0.14

Major Features

User Self-Service Capabilities

Restart Server: Users can restart their running JupyterLab containers directly from the control panel without admin intervention
Manage Volumes: Selective reset of persistent volumes (home/workspace/cache) when server is stopped - users choose which volumes to reset via checkbox interface

Technical Improvements

Frontend

Bootstrap 5 modal compatibility (data-bs-toggle, data-bs-target, btn-close)
RequireJS module loading for proper JavaScript execution
Font Awesome icons (fa-rotate for restart, fa-database for volumes)
Proper template inheritance extending JupyterHub's default home.html

Backend

New API endpoint: /api/users/{username}/manage-volumes accepting JSON body with volume array
ManageVolumesHandler processes multiple volumes with detailed success/failure response
Manual permission checking (admin or self) for API handlers
Comprehensive logging for all operations (frontend console + backend logs)

Infrastructure

Version management system with project.env and auto-increment on build
Makefile enhancements: increment_version, tag, stop, logs targets
Docker API integration via /var/run/docker.sock for volume and container management

Documentation

README updated with Features section and visual screenshots
CLAUDE.md created with architecture overview and configuration patterns
FEATURE_PLAN.md documenting implementation strategy
Journal tracking all substantive work

Version History

v3.0.14: Documentation updates, 3-second stop delay
v3.0.12: Multi-volume management, Bootstrap 5 fixes, icons
v2.11: Previous stable release

Upgrade Notes

No breaking changes. Existing deployments will seamlessly adopt new self-service features upon container restart.

Users will see new buttons on the JupyterHub control panel:

"Restart Server" (when server is running)
"Manage Volumes" (when server is stopped)

From: v2.11-cuda-12.9.1 To: v3.0.14_cuda-12.9.1_jh-5.4.2 Date: 2025-11-04
