Rubix

What is Rubix?

Python library that makes it easy to perform common DevOps tasks inside Jupyter Notebooks. E.g. plot Cloudwatch metrics, rollback your ECS/kubernetes app etc.

When to use it?

While Rubix can be used in many contexts, it's most useful for writing incident runbooks/playbooks. On-call can read instructions & execute steps right from the Jupyter Notebook. I wrote more about the use case here.

Why Jupyter Notebook?

• Ideal for quick incident response. Jupyter allows interleaving instructions and executable code.
• Rich HTML output makes it easy to plot graphs, show deployment status etc.
• Low friction way to edit/view/execute notebooks in a browser.

Documentation

Currently following integrations are supported in Rubix, would love to add more. Note that Jupyter Notebook supports executing shell commands & SQL queries out of the box.

• Rubix
  • Cloudwatch
  • Elastic Container Service (ECS)
  • Kubernetes

Installation

Rubix exclusively works with Jupyter notebooks. You can install Jupyter locally or use JupyterHub multi user setup. I also built nurtch (commercial) for easy multi user Jupyter setup.

• For your Jupyter/JupyterHub setup, just execute the following at the top of any notebook. Bang operator tells Jupyter to execute this as a terminal command.

!pip install rubix

• Rubix is pre-installed with nurtch multi-user Jupyter setup.
• Rubix is pre-installed with GitLab 11.4 onwards. See this video for instructions.

Usage

Complete documentation is linked above. Here are some usage examples.

Plot Cloudwatch Metrics

Rollback Service in ECS
