Overview

Containerd Shim Spin

The Containerd Shim Spin repository provides shim implementations for running WebAssembly (Wasm) / Wasm System Interface (WASI) workloads using runwasi as a library, whereby workloads built using the Spin framework can function similarly to container workloads in a Kubernetes environment.

Runtime Class Manager (Containerd Shim Lifecycle Operator)

The Runtime Class Manager, also known as the Containerd Shim Lifecycle Operator, is designed to automate and manage the lifecycle of containerd shims in a Kubernetes environment. This includes tasks like installation, update, removal, and configuration of shims, reducing manual errors and improving reliability in managing WebAssembly (Wasm) workloads and other containerd extensions.

Spin plugin for Kubernetes (spin kube)

The Spin plugin for Kubernetes is designed to enhance Kubernetes by enabling the execution of Wasm modules directly within a Kubernetes cluster. This plugin works by integrating with containerd shims, allowing Kubernetes to manage and run Wasm workloads in a way similar to traditional container workloads.

Spin Operator

The Spin Operator enables deploying Spin applications to Kubernetes. The foundation of this project is built using the kubebuilder framework. Spin Operator defines Spin App Custom Resource Definitions (CRDs). Spin Operator watches SpinApp Custom Resources e.g. Spin app image, replicas, schedulers and other user-defined values and realizes the desired state in the Kubernetes cluster. Spin Operator introduces a host of functionality such as resource-based scaling event-driven scaling and much more.
