Network Source of Truth (NSoT) is an API and web application front-end for managing IP addresses (IPAM), network devices, and network interfaces.
NSoT is designed to be a source of truth database and repository for tracking inventory and metadata of network entities to ease management and automation of network infrastructure.
Currently only IP address management (IPAM), device inventory, and network interfaces is on the road-map but it will evolve into more over time.
For more information please, see the documentation.
The latest documentation will always be available at http://nsot.readthedocs.org/en/latest/
Interactive API documentation can be found at /docs/
on a running NSoT server.
New versions will always be uploaded to PyPI regularly so it should be as easy as:
$ pip install nsot
Note: You'll need to have a reasonably recent version of npm to build front-end dependencies. (Minimum version tested is 1.3.24
)
We suggest setting up your test environment in a Python virtualenv:
$ virtualenv nsot
$ source nsot/bin/activate
Or, if you use virtualenvwrapper:
$ mkvirtualenv nsot
If you haven't already, make sure you set up git and add an SSH key to your GitHub account before proceeding!
After that, clone the repository into whichever directory you use for development and install the dependencies:
$ git clone git@github.com:dropbox/nsot.git
$ cd nsot
$ pip install -r requirements-dev.txt
$ python setup.py develop
For developement and testing, it's easiest to run NSoT behind a reverse proxy that handles authentication and sends a username via a special HTTP header. We've included a test proxy for running on development instances.
To get started, follow these steps:
# Initialize the config
$ nsot-server init
# Setup the database.
$ nsot-server upgrade
# Run the development reverse proxy (where $USER is the desired username)
$ nsot-server user_proxy $USER
# (In another terminal) Run the front-end server, remember to activate your
# virtualenv first if you need to
$ nsot-server start
Note: This quick start assumes that you're installing and running NSoT on your local system (aka localhost).
Now, point your web browser to http://localhost:8888 and explore the documentation!
All tests will automatically be run on Travis CI when pull requests are sent. However, it's beneficial to run the tests often during development:
$ py.test -v tests/
If you make any changes to the database models you'll need to generate a new migration. We use Django's built-in support for database migrations underneath, so for general schema changes is should be sufficient to just run:
$ nsot-server makemigrations
This will generate a new schema version. You can then sync to the latest version:
$ nsot-server migrate
Documentation is generated using Sphinx. If you just want to build and view the docs | you cd into the docs
directory and run make html
. Then point your browser | to docs/\_build/html/index.html
on your local filesystem.
If you're actively modifying the docs it's useful to run the autobuild server:
$ sphinx-autobuild docs docs/_build/html/
This will start a server listening on a port that you can browse to and will be automatically reloaded when you change any rst files. One downside of this approach is that is doesn't refresh when docstrings are modified.
We use a combination JavaScript utilities to do front-end development:
- npm - npm is used to manage our build dependencies
- bower - bower to manage our web dependencies
- gulp - gulp for building, linting, testing
Note: You do not have to install these yourself! When you run setup.py develop
, it will install and build all front-end components for you!
For the most part you shouldn't need to care about these details though if you want to add new build dependencies, for example gulp-concat, you would run the followiing:
# Install gulp-concat, updating package.json with a new devDependency
$ npm install gulp-concat --save-dev
# Writes out npm-shrinkwrap.json, including dev dependencies, so consistent
# build tools are used
$ npm shrinkwrap --dev
Adding new web dependencies are done through bower:
# Install lodaash, updating bower.json with the new dependency
$ bower install lodash --save
Unfortunately, bower doesn't have a shrinkwrap/freeze feature so you'll want to update the version string to make the version explicit for repeatable builds.
We make use of bower's "main file" concept to distribute only "main" files. Most packages don't consider consider the minified versions of their project to be their main files so you'll likely also need to update the overrides
section of bower.json
with which files to distribute.
If you would like to run the demo, make sure you've got NSoT installed, change to the demo
directory and run:
$ ./run_demo.sh
For the time being the best way to get support, provide feedback, ask questions, or to just talk shop is to find us on IRC at #nsot
on Freenode (irc://irc.freenode.net/nsot).
This project is stable and fully unit-tested, however as it is pre-1.0 it is still very much in flux and likely to have backwards-incompatible API changes for the time being. Also some documentation may describe steps not yet possible, or in some cases possible steps may not be fully documented.
