Ready to finish crafting your CodeQL Actions runner image? Following up on my previous post, it’s time to add Python 2 support to the Docker image. You’ll add to the multistage build, learn how to preserve symbolic links, and learn a trick for unpacking archives without needing to copy the archive into the image first.

Have you struggled with running CodeQL analysis on your own runners? You’re not alone. I figured that it was probably time to tackle this challenge to show you how to build the image, a few advanced Docker tricks, and a way to incorporate the scripts that the Actions team uses to build the official hosted runner VM images.

Buildroot comes with a lot of great features, but what good is a custom image if you can’t add your own binaries?

None of us like to wait. Time is precious, so we want to make the most of it. Unfortunately, if you’re just getting started with Buildroot it may seem like you’re spending a lot of time waiting for a toolchain to compile. In this post, we’ll look at ways to avoid that problem. Discover three easy ways to speed up your builds and spend more time creating, not waiting.
