jupyter-ml -- GPU ML Jupyter with CRDT MCP
Box Definition
jupyter-ml:
base: nvidia
candy:
- agent-forwarding
- jupyter-ml
- notebook-templates
- dbus
- charly
ports:
- "8888:8888"
platforms:
- linux/amd64
Candy Composition
The jupyter-ml candy is a Tier 2 environment-owning meta-layer that composes:
llama-cpp— llama.cpp prebuilt binaries + GGUF toolsunsloth— vLLM 0.19 cu130 inference engine + fine-tuning (unsloth + unsloth-zoo) + vLLM torch.compile patchjupyter-mcp— CRDT MCP extension (fastmcp + jupyter_mcp package)
Additional candies from the box:
agent-forwarding— SSH/GPG agent forwardingnotebook-templates— Starter notebooks (data candy, seeds /workspace)dbus— D-Bus session buscharly— OpenCharly CLI

Ports
| Port | Service |
|------|---------|
| 8888 | JupyterLab + MCP endpoint at /mcp |
Volumes
| Name | Path | Purpose | |------|------|---------| | workspace | /workspace | Persistent notebook storage | | models | ~/.cache/huggingface | HuggingFace model cache (from unsloth sub-candy) |
Service Environment Integration
This box receives env_provide variables from infrastructure candies when they are deployed:
| Variable | Injected by | Value |
|----------|------------|-------|
| OLLAMA_HOST | /charly-ollama:ollama | http://charly-ollama:11434 |
| PGHOST | /charly-infrastructure:postgresql | charly-postgresql |
| PGPORT | /charly-infrastructure:postgresql | 5432 |
| REDIS_URL | /charly-infrastructure:redis or /charly-infrastructure:valkey | redis://charly-<image>:6379 |
These variables are injected automatically into the container environment at charly config time when the corresponding service is deployed. No manual -e flags needed.
Key Capabilities
- JupyterLab with real-time collaboration (jupyter-collaboration, Y-CRDT)
- CRDT MCP Server at
/mcp— 11 tools for programmatic notebook access (server manages CRDT rooms invisibly; see/charly-jupyter:jupyter-mcpfor the auto-attach + canonicalization design) - PyTorch >= 2.10.0 with CUDA 13.0
- vLLM 0.19 inference engine
- Unsloth fine-tuning (LoRA, QLoRA)
- LangChain RAG stack (chromadb, faiss-cpu)
- Evaluation tools (evidently, sacrebleu, rouge-score)
- Notebook templates seeded into /workspace
Quick Start
