Autoscaling self-hosted runners with actions-runner-controller

If you want to use Github Actions with GHES, you will have to choose self-hosted runners because GitHub-hosted runners are not available. Installing self-hosted runners according to the official installation instructions can present issues such as a lack of idempotence and the inability to autoscale according to the job queue. There is a tool called actions-runner-controller that can run self-hosted runners while resolving these issues.

The past and future of Baikonur, an infrastructure-related OSS project

It's been a while. I'm @prog893, and I love writing long articles. I'd like to talk about Project Baikonur, a system I've been working on for a while now to make infrastructure-related tools open source. Project Baikonur is a project at our company to make Terraform modules, various infrastructure-related tools, and tools to improve development efficiency open source. It originally started as an internal open source project, but after going through various events explained in this article, we decided to make it publicly available on GitHub. We are making the modules and tools available for use outside the company as well.
