This project implements the Hydra specification for Kubernetes.
This is unstable, experimental, and subject to massively breaking changes. It may reflect the spec, or even features we are vetting before inclusion into the spec.
A relatively recent version of Scylla can be installed using Helm v3.
$ helm install scylla ./charts/scylla --waitSee the installation guide for more details.

Scylla is one of the monsters in Homer's Odyssey. Odysseus must steer his ship between Scylla and Charybdis. Scylla is sometimes portrayed as a hydra.
On occasion, we have been asked why Scylla is written in Rust instead of Go. There is no requirement in the Kubernetes world that Kubernetes controllers be written in Go. Many languages implement the Kubernetes API and can be used for creating controllers. We decided to write Scylla in Rust because the language allows us to write Kubernetes controllers with far less code. Rust's generics make it possible to quickly and succinctly describe custom Kubernetes API resources without requiring developers to run code generators. And Rust's Kubernetes library can easily switch between Kubernetes versions with ease. We recognize that Rust might not be to everyone's taste (and neither is Go). However, we are confident that Rust is a solid choice for writing maintainable and concise Kubernetes applications.
