This Terraform module creates the required infrastructure needed to host GitHub Actions self-hosted, auto-scaling runners on AWS spot instances. It provides the required logic to handle the life cycle for scaling up and down using a set of AWS Lambda functions. Runners are scaled down to zero to avoid costs when no workflows are active.

At Spotify, we have experimented with the Bazel build system since 2017. Over the years, the project has matured, and support for more languages and ecosystems have been added, thanks to the open source community and its maintainers at Google. In 2020, it became clear that the future of our client development required a unified build system that would scale well with our polyglot, multiplatform, and multimillion-line codebase.

So we focused more of our energy on Bazel, and we transitioned the iOS Spotify app to build completely with Bazel for our 200+ engineers — without missing a single weekly release for millions of our iOS users.

Walk — a terminal navigator.

Why another terminal navigator? I wanted something simple and minimalistic. Something to help me with faster navigation in the filesystem; a cd and ls replacement. So I build walk. It allows for quick navigation with fuzzy searching, cd integration is quite simple. And you can open vim right from the walk. That's it.
