In today's cloud-native landscape, GPU workloads are becoming increasingly critical. From training large language models to running inference APIs, organizations are investing heavily in GPU infrastructure. But with this investment comes a challenge: how do you safely test and deploy new GPU schedulers without risking your entire production environment?

Introduction​

Using runbooks can streamline and improve working with Kubernetes by automating repeatable tasks. Bonus point, we can do this using only open source tools.

This article is will be helpful to anyone interested in modern complex software development.

Overview​

This documentation assumes basic knowledge of Kubernetes and kubectl. To learn or refresh on container orchestration related concepts, please refer to the official documentation:

GitOps with Kubernetes​

Software development tooling and processes have evolved rapidly in last decade to meet growing needs of developers. On top of mastering, often a few, programing languages and paradigms, software developers must learn to navigate increasingly complex landscape of tools and processes.

Expose local Kubernetes service on internet using ngrok​

Working with local Kubernetes cluster such as minikube, k3s, microk8s or others is great for testing new features, experimenting and running POCs. Once you are ready with a cool new functionality or just want to share quickly results of your work with colleagues or customers, well you have to push everything to an online cluster. It might not be an issue if you have good CI/CD pipeline setup, but most of the time it’s simply too much effort for a simple one-off demo.

Portable Kubernetes management with kubectl in Docker container​

Saying that Kubernetes is becoming mainstream would be an understatement. In fact, it has influenced how modern distributed systems are designed and operated. By abstracting away infrastructure concerns we are able to leverage Kubernetes as a “platform to build platforms” or “cloud operating system” with lots of obvious benefits, but also development and operational challenges.
