aws-bootstrap-g4dn 0.11.0

Bootstrap AWS EC2 GPU instances for hybrid local-remote development

aws-bootstrap-g4dn

---

One command to go from zero to a fully configured GPU dev box on AWS — with CUDA-matched PyTorch, Jupyter, SSH aliases, and a GPU benchmark ready to run.

aws-bootstrap launch          # Spot g4dn.xlarge in ~3 minutes
ssh aws-gpu1                  # You're in, venv activated, PyTorch works

✨ Key Features

	Feature	Details
🚀	One-command launch	Spot (default) or on-demand, with automatic fallback on capacity errors
🔑	Auto SSH config	Adds aws-gpu1 alias to ~/.ssh/config — no IP juggling. Cleaned up on terminate
🐍	CUDA-aware PyTorch	Detects the installed CUDA toolkit (nvcc) and installs PyTorch from the matching wheel index — no more torch.version.cuda mismatches
✅	PyTorch smoke test	Runs a quick torch.cuda matmul after setup to verify the GPU stack works end-to-end
📊	GPU benchmark included	CNN (MNIST) + Transformer benchmarks with FP16/FP32/BF16 precision and tqdm progress
📓	Jupyter ready	Lab server auto-starts as a systemd service on port 8888 — just SSH tunnel and open
🖥️	status --gpu	Shows CUDA toolkit version, driver max, GPU architecture, spot pricing, uptime, and estimated cost
💾	EBS data volumes	Attach persistent storage at /data — survives spot interruptions and termination, reattach to new instances
🗑️	Clean terminate	Stops instances, removes SSH aliases, cleans up EBS volumes (or preserves with --keep-ebs)
🤖	Agent Skill	Included Claude Code plugin lets LLM agents autonomously provision, manage, and tear down GPU instances

🎯 Target Workflows

1. Jupyter server-client — Jupyter runs on the instance, connect from your local browser
2. VSCode Remote SSH — opens ~/workspace with pre-configured CUDA debug/build tasks and an example .cu file
3. NVIDIA Nsight remote debugging — GPU debugging over SSH

---

Requirements

1. AWS profile configured with relevant permissions (profile name can be passed via --profile or read from AWS_PROFILE env var)
2. AWS CLI v2 — see here
3. Python 3.12+ and uv
4. An SSH key pair (see below)

Installation

From PyPI

pip install aws-bootstrap-g4dn

With uvx (no install needed)

uvx runs the CLI directly in a temporary environment — no global install required:

uvx --from aws-bootstrap-g4dn aws-bootstrap launch
uvx --from aws-bootstrap-g4dn aws-bootstrap status
uvx --from aws-bootstrap-g4dn aws-bootstrap terminate

From source (development)

git clone https://github.com/promptromp/aws-bootstrap-g4dn.git
cd aws-bootstrap-g4dn
uv venv
uv sync

All methods install the aws-bootstrap CLI.

SSH Key Setup

The CLI expects an Ed25519 SSH public key at ~/.ssh/id_ed25519.pub by default. If you don't have one, generate it:

ssh-keygen -t ed25519

Accept the default path (~/.ssh/id_ed25519) and optionally set a passphrase. The key pair will be imported into AWS automatically on first launch.

To use a different key, pass --key-path:

aws-bootstrap launch --key-path ~/.ssh/my_other_key.pub

Usage

🚀 Launching an Instance

# Show available commands
aws-bootstrap --help

# Dry run — validates AMI lookup, key import, and security group without launching
aws-bootstrap launch --dry-run

# Launch a spot g4dn.xlarge (default)
aws-bootstrap launch

# Launch on-demand in a specific region with a custom instance type
aws-bootstrap launch --on-demand --instance-type g5.xlarge --region us-east-1

# Launch without running the remote setup script
aws-bootstrap launch --no-setup

# Use a specific Python version in the remote venv
aws-bootstrap launch --python-version 3.13

# Use a non-default SSH port
aws-bootstrap launch --ssh-port 2222

# Attach a persistent EBS data volume (96 GB gp3, mounted at /data)
aws-bootstrap launch --ebs-storage 96

# Reattach an existing EBS volume from a previous instance
aws-bootstrap launch --ebs-volume-id vol-0abc123def456

# Use a specific AWS profile
aws-bootstrap launch --profile my-aws-profile

After launch, the CLI:

1. Creates/attaches EBS volume (if --ebs-storage or --ebs-volume-id was specified)
2. Adds an SSH alias (e.g. aws-gpu1) to ~/.ssh/config
3. Runs remote setup — installs utilities, creates a Python venv, installs CUDA-matched PyTorch, sets up Jupyter
4. Mounts EBS volume at /data (if applicable — formats new volumes, mounts existing ones as-is)
5. Runs a CUDA smoke test — verifies torch.cuda.is_available() and runs a quick GPU matmul
6. Prints connection commands — SSH, Jupyter tunnel, GPU benchmark, and terminate

ssh aws-gpu1                  # venv auto-activates on login

🔧 What Remote Setup Does

The setup script runs automatically on the instance after SSH becomes available:

Step	What
GPU verify	Confirms nvidia-smi and nvcc are working
Utilities	Installs htop, tmux, tree, jq, ffmpeg
Python venv	Creates ~/venv with uv, auto-activates in ~/.bashrc. Use --python-version to pin a specific Python (e.g. 3.13)
CUDA-aware PyTorch	Detects CUDA toolkit version → installs PyTorch from the matching cu{TAG} wheel index
CUDA smoke test	Runs torch.cuda.is_available() + GPU matmul to verify the stack
GPU benchmark	Copies gpu_benchmark.py to ~/gpu_benchmark.py
GPU smoke test notebook	Copies gpu_smoke_test.ipynb to ~/gpu_smoke_test.ipynb (open in JupyterLab)
Jupyter	Configures and starts JupyterLab as a systemd service on port 8888
SSH keepalive	Configures server-side keepalive to prevent idle disconnects
VSCode workspace	Creates ~/workspace/.vscode/ with launch.json and tasks.json (auto-detected cuda-gdb path and GPU arch), plus an example saxpy.cu

📊 GPU Benchmark

A GPU throughput benchmark is pre-installed at ~/gpu_benchmark.py on every instance:

# Run both CNN and Transformer benchmarks (default)
ssh aws-gpu1 'python ~/gpu_benchmark.py'

# CNN only, quick run
ssh aws-gpu1 'python ~/gpu_benchmark.py --mode cnn --benchmark-batches 20'

# Transformer only with custom batch size
ssh aws-gpu1 'python ~/gpu_benchmark.py --mode transformer --transformer-batch-size 16'

# Run CUDA diagnostics first (tests FP16/FP32 matmul, autocast, etc.)
ssh aws-gpu1 'python ~/gpu_benchmark.py --diagnose'

# Force FP32 precision (if FP16 has issues on your GPU)
ssh aws-gpu1 'python ~/gpu_benchmark.py --precision fp32'

Reports: iterations/sec, samples/sec, peak GPU memory, and avg batch time for each model.

📓 Jupyter (via SSH Tunnel)

ssh -NL 8888:localhost:8888 aws-gpu1
# Then open: http://localhost:8888

Or with explicit key/IP:

ssh -i ~/.ssh/id_ed25519 -NL 8888:localhost:8888 ubuntu@<public-ip>

A GPU smoke test notebook (~/gpu_smoke_test.ipynb) is pre-installed on every instance. Open it in JupyterLab to interactively verify the CUDA stack, run FP32/FP16 matmuls, train a small CNN on MNIST, and visualise training loss and GPU memory usage.

🖥️ VSCode Remote SSH

The remote setup creates a ~/workspace folder with pre-configured CUDA debug and build tasks:

~/workspace/
├── .vscode/
│   ├── launch.json   # CUDA debug configs (cuda-gdb path auto-detected)
│   └── tasks.json    # nvcc build tasks (GPU arch auto-detected, e.g. sm_75)
└── saxpy.cu          # Example CUDA source — open and press F5 to debug

Connect directly from your terminal:

code --folder-uri vscode-remote://ssh-remote+aws-gpu1/home/ubuntu/workspace

Then install the Nsight VSCE extension on the remote when prompted. Open saxpy.cu, set a breakpoint, and press F5.

See Nsight remote profiling guide for more details on CUDA debugging and profiling workflows.

📤 Structured Output

All commands support --output / -o for machine-readable output — useful for scripting, piping to jq, or LLM tool-use:

# JSON output (pipe to jq)
aws-bootstrap -o json status
aws-bootstrap -o json status | jq '.instances[0].instance_id'

# YAML output
aws-bootstrap -o yaml status

# Table output
aws-bootstrap -o table status

# Works with all commands
aws-bootstrap -o json list instance-types | jq '.[].instance_type'
aws-bootstrap -o json launch --dry-run
aws-bootstrap -o json terminate --yes
aws-bootstrap -o json cleanup --dry-run

Supported formats: text (default, human-readable with color), json, yaml, table. Commands that require confirmation (terminate, cleanup) require --yes in structured output modes.

aws-bootstrap cleanup --include-ebs --dry-run

# Skip confirmation prompt
aws-bootstrap cleanup --yes

status --gpu reports both the installed CUDA toolkit version (from nvcc) and the maximum CUDA version supported by the driver (from nvidia-smi), so you can see at a glance whether they match:

CUDA: 12.8 (driver supports up to 13.0)

SSH aliases are managed automatically — they're created on launch, shown in status, and cleaned up on terminate. Aliases use sequential numbering (aws-gpu1, aws-gpu2, etc.) and never reuse numbers from previous instances. You can use aliases anywhere you'd use an instance ID, e.g. aws-bootstrap terminate aws-gpu1.

EBS Data Volumes

Attach persistent EBS storage to keep datasets and model checkpoints across instance lifecycles. Volumes are mounted at /data and persist independently of the instance.

# Create a new 96 GB gp3 volume, formatted and mounted at /data
aws-bootstrap launch --ebs-storage 96

# After terminating with --keep-ebs, reattach the same volume to a new instance
aws-bootstrap terminate --keep-ebs
# Output: Preserving EBS volume: vol-0abc123...
#         Reattach with: aws-bootstrap launch --ebs-volume-id vol-0abc123...

aws-bootstrap launch --ebs-volume-id vol-0abc123def456

Key behaviors:

• --ebs-storage and --ebs-volume-id are mutually exclusive
• New volumes are formatted as ext4; existing volumes are mounted as-is
• Volumes are tagged for automatic discovery by status and terminate
• terminate deletes data volumes by default; use --keep-ebs to preserve them
• Orphan cleanup — use aws-bootstrap cleanup --include-ebs to find and delete orphan volumes (e.g. from spot interruptions or forgotten --keep-ebs volumes). Use --dry-run to preview
• Spot-safe — data volumes survive spot interruptions. If AWS reclaims your instance, the volume detaches automatically and can be reattached to a new instance with --ebs-volume-id
• EBS volumes must be in the same availability zone as the instance
• Mount failures are non-fatal — the instance remains usable

EC2 vCPU Quotas

AWS accounts have service quotas that limit how many vCPUs you can run per instance family. New or lightly-used accounts often have a default quota of 0 vCPUs for GPU instance families (G and VT), which will cause errors on launch:

• Spot: MaxSpotInstanceCountExceeded
• On-Demand: VcpuLimitExceeded

Check your current quotas (g4dn.xlarge requires at least 4 vCPUs):

# Built-in: show all GPU family quotas
aws-bootstrap quota show

# Show only G/VT family quotas
aws-bootstrap quota show --family gvt

# Show P family quotas (P2 through P6)
aws-bootstrap quota show --family p

# Or use the AWS CLI directly:
aws service-quotas get-service-quota \
  --service-code ec2 \
  --quota-code L-3819A6DF \
  --region us-west-2

Request increases:

# Built-in: request a G/VT spot quota increase (default family)
aws-bootstrap quota request --type spot --desired-value 4

# Request a P family spot quota increase
aws-bootstrap quota request --family p --type spot --desired-value 192

# Check request status
aws-bootstrap quota history

# Or use the AWS CLI directly:
aws service-quotas request-service-quota-increase \
  --service-code ec2 \
  --quota-code L-3819A6DF \
  --desired-value 4 \
  --region us-west-2

Quota codes may vary by region or account type. To list the actual codes in your region:

# List all G/VT-related quotas
aws service-quotas list-service-quotas \
  --service-code ec2 \
  --region us-west-2 \
  --query "Quotas[?contains(QuotaName, 'G and VT')].[QuotaCode,QuotaName,Value]" \
  --output table

Common quota codes:

Family	Type	Code	Description
G/VT	Spot	L-3819A6DF	All G and VT Spot Instance Requests
G/VT	On-Demand	L-DB2E81BA	Running On-Demand G and VT instances
P	Spot	L-7212CCBC	All P Spot Instance Requests
P	On-Demand	L-417A185B	Running On-Demand P instances
DL	Spot	L-85EED4F7	All DL Spot Instance Requests
DL	On-Demand	L-6E869C2A	Running On-Demand DL instances

Small increases (4-8 vCPUs) are typically auto-approved within minutes. You can also request increases via the Service Quotas console. While waiting, you can test the full launch/poll/SSH flow with a non-GPU instance type:

aws-bootstrap launch --instance-type t3.medium --ami-filter "ubuntu/images/hvm-ssd-gp3/ubuntu-noble-24.04-amd64-server-*"
