Summary
As technology professionals, we need to make sure that the software we write is reliably bug free and the best way to do that is with a continuous integration and continuous deployment pipeline. This week we spoke with Pierre Tardy about Buildbot, which is a Python framework for building and maintaining CI/CD workflows to keep our software projects on track.

Interview with Pierre Tardy
- Introductions
- How did you get introduced to Python? – Chris
- For anyone who isn’t familiar with it can you explain what Buildbot is? – Tobias
- What was the original inspiration for creating the project? – Tobias
- How did you get involved in the project? – Tobias
- Can you describe the internal architecture of Buildbot and outline how a typical workflow would look? – Tobias
- There are a number of packages out on PyPI for doing subprocess invocation and control, in addition to the functions in the standard library. Which does buildbot use and why? – Chris
- What makes Buildbot stand out from other CI/CD options that are available today? – Tobias
- Scaling a large CI/CD system can become a challenge. What are some of the limiting factors in the Buildbot architecture and in what ways have you seen people work to overcome them? – Tobias
- Are there any design or architecture choices that you would change in the project if you were to start it over? – Tobias
- If you were starting from scratch on implementing buildbot today, would you still use Python? Why? – Chris
- What are some of the most difficult challenges that have been faced in the creation and evolution of the project? – Tobias
- What are some of the most notable uses of Buildbot and how do they uniquely leverage the capabilities of the framework? – Tobias
- What are some of the biggest challenges that people face when beginning to implement Buildbot in their architecture? – Tobias
- Does buildbot support the use of docker or public clouds as a part of the build process? – Chris
- I know that the execution engine for Buildbot is written in Twisted. What benefits does that provide and how has that influenced any efforts for providing Python 3 support? – Tobias
- Does buildbot support build parallelization at all? For instance splitting one very long test run up into 3 instances each running a section of tests to cut build time? – Chris
- What are some of the most requested features for the project and are there any that would be unreasonably difficult to implement due to the current design of the project? – Tobias
- Does buildbot offer a plugin system like Jenkins does, or is there some other approach it uses for custom extensions to the base buildbot functionality? – Chris
- Managing a reliable build pipeline can be operationally challenging. What are some of the thorniest problems for Buildbot in this regard and what are some of the mechanisms that are built in to simplify the operational characteristics? – Tobias
- What were some of the challenges around supporting slaves running on platforms with very different environmental characteristics like Microsoft Windows? – Chris
- What is on the roadmap for Buildbot? – Tobias
