jlaura/restful-spice repository overview

⁠RESTful Spice a.k.a. Pfeffernusse

This project uses the NAIF supplied spice data and exposes it as a RESTful service. This is a prototype proof of concept with no documentation. As an alpha product, Pfeffernusse is not ready for production. The functionality of pfeffernusse is also currently conflated some with the SpiceRack project. In coming releases we will separate these microservices with spicerack supporting management of kernels, distributed synchronization, and a light RESTful API to report kernel availability. This project will then be able to focus on exploitation of the kernels and generation of higher order data packages, e.g., a Community Sensor Model compliant Image Support Data (ISD) blob.

⁠Dependencies

The module depends on:

• spiceypy

• flask

• sqlalchemy

• numpy

Optionally, to run the example ipython notebooks.

• pvl
• requests

⁠Running the App in Development Mode

then in a browser navigate to localhost:5000. The app is running in debug mode by default (can be changed at the end of run.py).

⁠Running the App as a MicroService

This is how we intend Pfeffernusse to be deployed. Simply running the following will get Pfeffernusse up and running as a Docker container.

⁠Running the App with a different Spice Root

The app assumes that spice data is stored in /data/spice. This is done intentionally as we intend the application to be run as a containerized microservice. If you will to change the root directory:

1. Inside of /bin/create_spice_db.py change the ROOT to the desired root.
2. Remove mk.db and rerun /bin/create_spice_db.py to update the PATH info that is being stored in the database.
