⚠️ Warning ⚠️ The project has recently been renamed from QHub to Nebari. If your deployment is still managed by qhub, performing an in place upgrade will IRREVOCABLY BREAK your deployment. This will cause you to lose any data stored on the platform, including but not limited to, NFS (file system) data, conda-store environments, Keycloak users and groups, etc. Make sure to back up your data before attempting an upgrade.

Automated data science platform. From JupyterHub to Cloud environments with Dask Gateway.

Nebari is an open source data platform that enables users to build and maintain cost-effective and scalable compute platforms on HPC or Kubernetes with minimal DevOps overhead.

This repository details the Nebari (Kubernetes) version.

Not sure what to choose? Check out our Setup Initialization page.

QHub HPC

The HPC version of Nebari is based on OpenHPC.

NOTE: The tool is currently under development. Curious? Check out the Nebari HPC repository.

Nebari

The Kubernetes version of Nebari uses Terraform, Helm, and GitHub Actions.

• Terraform handles the build, change, and versioning of the infrastructure.
• Helm helps to define, install, and manage Kubernetes resources.
• GitHub Actions is used to automatically create commits when the configuration file (nebari-config.yaml) is rendered, as well as to kick off the deployment action.

Nebari aims to abstract all these complexities for its users. Hence, it is not necessary to know any of the technologies mentioned above to have your project successfully deployed.

TLDR: If you know GitHub and feel comfortable generating and using API keys, you should have all it takes to deploy and maintain your system without the need for a dedicated DevOps team. No need to learn Kubernetes, Terraform, or Helm.

Cloud Providers ☁️

Nebari offers out-of-the-box support for the major public cloud providers: Digital Ocean, Amazon AWS, GCP, and Microsoft Azure.

Installation 💻

Pre-requisites

• Operating System: Currently, Nebari supports development on macOS and Linux operating systems. Windows is NOT supported. However, we would welcome contributions that add and improve support for Windows.
• You need Python >= 3.7 on your local machine or virtual environment to work on Nebari.
• Adopting virtual environments (conda, pipenv or venv) is also encouraged.

Install Nebari

To install Nebari type the following commands in your command line:

• Install using conda:

  conda install -c conda-forge nebari
  
  # if you prefer using mamba
  mamba install -c conda-forge nebari

• Install using pip:

  pip install nebari

Once finished, you can check Nebari's version (and additional CLI arguments) by typing:

nebari --help

If successful, the CLI output will be similar to the following:

usage: nebari [-h] [-v] {deploy,destroy,render,init,validate} ...

Nebari command line

positional arguments:
  {deploy,destroy,render,init,validate}
                        Nebari

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         Nebari version

Usage 🚀

Nebari requires setting multiple environment variables to automate the deployments fully. For details on obtaining those variables, check the Nebari Get started documentation.

Once all the necessary credentials are gathered and set as UNIX environment variables, Nebari can be deployed in minutes.

For detailed step-by-step instructions on how to deploy Nebari, check the Nebari documentation.

Code of Conduct 📖

To guarantee a welcoming and friendly community, we require all community members to follow our Code of Conduct.

Ongoing Support

The v0.4.0 release introduced many changes that will irrevocably break your deployment if you attempt an in-place upgrade; for details, see our RELEASE notes. To focus on the future direction of the project, we have decided as a team that we will provide limited support for older versions. Any new user is encouraged to use v0.4.0 or greater.

If you're using an older version of Nebari and would like professional support, please get in touch with the Nebari development team.
