nbpull 0.1.0

🔍 Read-only CLI tool to pull IPAM data from NetBox

🔍 nbpull

Read-only CLI tool to pull IPAM data from NetBox.

🔒 Safety guarantee: nbpull only reads data from NetBox. No POST / PUT / PATCH / DELETE requests are ever made. The HTTP client is hardcoded to GET-only — this invariant is enforced by code structure and verified by tests.

---

✨ Features

• 📡 Prefixes — list and filter IPAM prefixes
• 🖥️ IP Addresses — query IP address allocations
• 🏷️ VLANs — browse VLAN assignments
• 🔀 VRFs — inspect VRF instances
• 📦 Batch queries — check many prefixes at once from a TOML file
• 🎨 Rich table output (default) or JSON (--format json)
• 🔎 Filter by status, VRF, tenant, site, tag, or free-text search
• ⚡ Async HTTP with automatic pagination
• 🔒 Strict typing (mypy strict mode + Pydantic v2)

nbpull prefixes	List IPAM prefixes
nbpull ip-addresses	List IP addresses
nbpull vlans	List VLANs
nbpull vrfs	List VRFs
nbpull batch-prefixes	Query multiple prefixes from a TOML file

Common Flags

Flag	Description
--status	Filter by status (active, reserved, deprecated, container)
--vrf	Filter by VRF name
--tenant	Filter by tenant name
--site	Filter by site name
--tag	Filter by tag slug

NETBOX_TOKEN	✅	—	API token (read-only recommended)
NETBOX_PAGE_SIZE	❌	100	Results per API page
NETBOX_TIMEOUT	❌	30	Request timeout (seconds)
NETBOX_VERIFY_SSL	❌	true	Verify SSL certificates

See docs/configuration.md for details on token setup and SSL options.

📦 Batch Queries

Create a TOML file to query multiple prefixes in one run:

prefixes = [
    "10.0.0.0/8",
    "172.16.0.0/12",
    "192.168.0.0/16",
]

[filters]
# status = "active"
# vrf = "Production"

nbpull batch-prefixes --file prefixes.toml --status-only

🛠️ Development

Prerequisites

• Python 3.13+
• uv — fast Python package manager

Setup

git clone https://github.com/Champion2005/nbpull.git
cd nbpull
make install    # Install dependencies

Commands

make all        # format → lint → typecheck → test
make test       # unit tests (no network)
make lint       # ruff linter
make format     # auto-format with ruff
make typecheck  # mypy strict mode
make test-integration  # hits real NetBox API

Running Tests

Unit tests use mocked HTTP responses and require no network access:

make test

Integration tests require NETBOX_URL and NETBOX_TOKEN:

make test-integration
