A Rust Controller for Kubernetes

To teach myself Kubernetes in general and controllers in particular, I previously developed one in Java. This week, I decided to do the same in Rust by following the same steps I did.

1. My First Cup of Rust
2. My Second Cup of Rust
3. The Rustlings Exercises – Part 1
4. The Rustlings Exercises – Part 2
5. Rust on the Front-End
6. A Rust Controller for Kubernetes (this post)

The Guiding Principle

The guiding principle is creating a Kubernetes controller that watches pods’ lifecycle and injects a sidecar into them. When Kubernetes schedules the pod, the controller schedules the sidecar; when it deletes the former, it deletes the latter as well.
