Krustlet is a Kubernetes kubelet written in Rust that runs WebAssembly (WASI) workloads instead of containers, using a wasmtime-based runtime. It listens on the Kubernetes event stream for pods assigned via tolerations and schedules wasm32-wasi workloads onto the node.
Use cases
- run webassembly workloads in a kubernetes cluster
- schedule wasm pods on a kubernetes node without containers
- build a custom kubelet in rust
- run wasi applications with wasmtime on kubernetes
- extend kubernetes to support wasm32-wasi workloads
When to choose
- you want to run WASI workloads on Kubernetes nodes instead of container images
- you need a reference implementation for writing a custom kubelet in Rust
- you are experimenting with WebAssembly in Kubernetes
When to avoid
- you need an actively maintained project - maintainers have moved on and it is no longer maintained
- you need production-grade container workload support
- you want a supported way to run wasm on Kubernetes today - consider newer alternatives like spinKube or wasmCloud
