⚠️ This project is currently not actively maintained. Most of the other maintainers have moved on to other WebAssembly related projects. This project could definitely still be useful to anyone who wants to write a custom Kubelet and its sister project Krator is a state machine-based solution for writing Kubernetes controllers/operators in Rust. If anyone is interested in maintaining these projects, please feel free to reach out!

Krustlet: Kubernetes Kubelet in Rust for running WASM

📯 Krustlet 1.0 coming soon!

Krustlet acts as a Kubelet by listening on the event stream for new pods that the scheduler assigns to it based on specific Kubernetes tolerations.

The default implementation of Krustlet listens for the architecture wasm32-wasi and schedules those workloads to run in a wasmtime-based runtime instead of a container runtime.
