Abstract
Jyrki Pulliainen - Packaging in packaging: dh-virtualenv Deploying your software can become a tricky task, regardless of the language. In the spirit of the Python conferences, every conference needs at least one packaging talk. This talk is about dh-virtualenv. It's a Python packaging tool aimed for Debian-based systems and for deployment flows that already take advantage of Debian packaging with Python virtualenvs ----- [Dh-virtualenv] is an open source tool developed at Spotify. We use it to ease deploying our Python software to production. We built dh-virtualenv as a tool that fits our existing continuous integration flow with a dedicated sbuild server. As we were already packaging software in Debian packages, the aim of dh-virtualenv was to make transition to virtualenv based installations as smooth as possible. This talk covers how you can use dh-virtualenv to help you deploy your software to production, where you are already running a Debian-based system, such as Ubuntu, and what are the advantages and disadvantages of the approach over other existing and popular techniques. We will discuss the deploying as a problem in general, look into building a dh-vritualenv-backed package, and in the end, look into how dh-virtualenv was actually made. Goal is that after this presentation you know how to make your Debian/Ubuntu deployments easier! [dh-virtualenv] if fully open sourced, production tested software, licensed under GPLv2+ and available in Debian testing and unstable. More information of it is also available in our [blogpost]. Talk outline: 1. Introduction & overview (3min) * Who am I? * Why am I fiddling with Python packaging? * What do you get out of this talk? 2. Different shortcomings of Python deployments (5min) * Native system packages * Virtualenv based installations * Containers, virtual machine images 3. dh-virtualenv (10 min) * What is dh-virtualenv? * Thought behind dh-virtualenv * Advantages over others * Requirements for your deployment flow * Short intro to packaging Sentry with dh-virtualenv 4. How is it built? (10 min) * Debian package building flow primer * How dh-virtualenv fits that flow * What does it do build time and why?
