xcengine

xcube tools for compute engines

Overview

xcengine provides a command xcetool which converts a Jupyter Python notebook to a compute engine. A compute engine consists of:

• A docker container image packaging the notebook code, a Python environment, and an xcube server component, letting the notebook results be served over multiple supported APIs and explored in the interactive xcube viewer.
• An accompanying CWL file defining an OGC Earth Observation Application Package using the container image. This lets your notebook code run as part of a processing workflow on any EOAP platform.

In the conversion process, xcengine tries to maximize convenience for the user by requiring as little extra configuration and input as possible. Input variables and their types can be defined by tagging a notebook cell (similarly to papermill), and output datasets are automatically extracted from the notebook’s environment. Some user configuration is unavoidable, but xcengine automates much of the boilerplate required to create an EOAP.
