Yeah, this is about my last summer. But I promise to focus on the story of how I was able to do four amazing lightning talks with Python and a harmonica.

This one is not about technical stuff, it is about finding something that python overlaps with your hobbies and sharing it back to the community.

This talk is about writing songs and playing music with python. Back in 2017 I came to know FoxDot, a python wrapper around SuperCollider, which is a super popular open source synthesizer. Since then, I have been using it to create entertaining lighting talks and would like to cover a bit more than just a lightning talk this time.

Applications and services rely on configuration data in order to be customized and we will talk about how to keep them in a safer place other than plaintext configuration files.

The configparser module is Python's standard configuration file parser and many projects rely on it to achieve easy configuration with plaintext files. OpenStack Common Libraries (Oslo) has an alternative called oslo.config with additional sources of input like command line arguments or environment variables. With the addition of a feature called source drivers last year, we are now able to increase the security of configuration values storing them in a safer place.

This talk focuses on the new source driver that integrates Oslo.Config and Castellan, another Olso module specialized in talking to secret managers, and how we can store our sensitive configuration data using HashiCorp Vault.

This talk covers oslo.config as a replacement option for ConfigParser, ArgumentParser and os.environ integrating all of their main features.

Many applications and services rely on configuration data to behave according to a set of specific needs.

The standard library gives us ConfigParser, ArgumentParser and os.environ used for easy configuration via plaintext configuration files, command line arguments and environment variables, but they don't come with batteries included to integrate with each other.

OpenStack Common Libraries (Oslo) has an enhanced alternative called oslo.config with support to config files, command line arguments, environment, option deprecation, and much more. With the recent addition of source drivers feature, it is also possible to increase the security of config values storing them in a safer place like a secret manager. Using oslo.config over the standard library options is an easy way to achieve flexibility and also become compliant with security matters.
