A high level overview of the SpinKube sub-projects.

Project Overview

SpinKube is a new open source project that streamlines the experience of developing, deploying, and operating Wasm workloads on Kubernetes, using Spin in tandem with the runwasi and runtime class manager (formerly KWasm) open source projects.

With SpinKube, you can leverage the advantages of using WebAssembly (Wasm) for your workloads:

  • Artifacts are significantly smaller in size compared to container images.
  • Artifacts can be quickly fetched over the network and started much faster (*Note: We are aware of several optimizations that still need to be implemented to enhance the startup time for workloads).
  • Substantially fewer resources are required during idle times.

Thanks to Spin Operator, we can do all of this while integrating with Kubernetes primitives (DNS, probes, autoscaling, metrics, and many more cloud native and CNCF projects).

Spin Operator watches Spin App Custom Resources and realizes the desired state in the Kubernetes cluster. The foundation of this project was built using the kubebuilder framework and contains a Spin App Custom Resource Definition (CRD) and controller.
