Primary Use Case

Krustlet is used to schedule and run Kubernetes pods that target the wasm32-wasi architecture, allowing developers to run WebAssembly modules as workloads within Kubernetes clusters. It is ideal for users interested in integrating WASM workloads into Kubernetes environments or building custom Kubelets using Rust.

Key Features

Kubelet implementation written in Rust

Supports scheduling of wasm32-wasi architecture workloads

Runs WASM workloads using wasmtime runtime instead of container runtimes

Listens to Kubernetes event streams for pod assignments based on tolerations

Integration with Kubernetes scheduler and pod lifecycle

Sister project Krator for writing Kubernetes controllers/operators in Rust

Community support via Kubernetes Slack and public calls

Adopts CNCF Code of Conduct

Insights & Recommendations

This project is currently not actively maintained and most maintainers have shifted focus to other WebAssembly-related projects. It remains useful for those wanting to experiment with custom Kubelets or WASM workloads in Kubernetes. Users interested in maintaining or contributing are encouraged to reach out to the community.

Smart Usage Notes

Leverage Krustlet to run lightweight WebAssembly workloads for sandboxed execution, reducing attack surface compared to traditional containers.Integrate Krustlet in DevSecOps pipelines to enforce WASM-based workload policies and improve container security posture.Use Krustlet's Rust-based implementation to build custom Kubelets with enhanced security features and memory safety.Combine Krustlet with runtime security tools to monitor WASM workloads for anomalous behavior and potential exploitation.Explore Krustlet as a platform for developing secure multi-tenant Kubernetes environments with workload isolation via WASM.
