JuliaCon 2023

Julia’s CI landscape has seen some notable improvements, both with respect to the compute and the tooling available. In this talk, we’ll demonstrate how you can make the best use of Buildkite for your packages in the Julia ecosystem from start to finish - Including testing on GPUs!
Since each package’s CI requirements are likely to vary from each other, we’ll talk about plugins that can help make your lives a bit easier, including tasks such as:
- Securely using secrets in your workflows
- Running workflows within isolated, reproducible sandboxes
- Easily customizing such sandboxes on the fly
- Avoiding boilerplate with template workflows
- Ensuring code integrity is maintained before running sensitive workflows

For each plugin, we’ll delve into the motivation behind the plugin first, followed by some small implementation details users need to know about to properly use each.
We’ll also present simple, toy examples of all this tooling so that users can reference them while building their own, more complex pipelines.
Finally, we’ll showcase some real examples where these plugins are put to good use by some of the packages in our ecosystem. Come, let’s talk CI!
