A library on top of either pex or conda-packto make your Python code easily available on a cluster

Project description


cluster-pack is a library on top of either pex or conda-pack to make your Python code easily available on a cluster.

Its goal is to make your prod/dev Python code & libraries easiliy available on any cluster. cluster-pack supports HDFS/S3 as a distributed storage.

The first examples use Skein (a simple library for deploying applications on Apache YARN) and PySpark with HDFS storage. We intend to add more examples for other applications (like Dask, Ray) and S3 storage.

An introducing blog post can be found here.



Install with Pip

$ pip install cluster-pack

Install from source

$ git clone
$ cd cluster-pack
$ pip install .


cluster-pack supports Python ≥3.6.


  • Ships a package with all the dependencies from your current virtual environment or your conda environment

  • Stores metadata for an environment

  • Supports "under development" mode by taking advantage of pip's editable installs mode, all editable requirements will be uploaded all the time, making local changes directly visible on the cluster

  • Interactive (Jupyter notebook) mode

  • Provides config helpers to directly use the uploaded zip file inside your application

  • Launching jobs from jobs by propagating all artifacts

Basic examples with skein

  1. Interactive mode

  2. Self shipping project

Basic examples with PySpark

  1. PySpark with HDFS on Yarn

  2. Docker with PySpark on S3
