# kwasm-operator

This Kubernetes Operators uses [KWasm/kwasm-node-installer](https://github.com/KWasm/kwasm-node-installer) to add WebAssembly support to your Kubernetes Nodes. It works with local and managed cloud K8s distributions based on Ubuntu/Debian with Containerd, including [MiniKube, MicroK8s, AKS, GKE, and EKS](https://github.com/KWasm/kwasm-node-installer#supported-kubernetes-distributions).

> **Warning**

> Only for development or evaluation purpose. Your nodes may get damaged!

> **Note**

> If you are searching for a production ready WebAssembly integration for your Kubernetes cluster, reach out to [Liquid Reply](https://www.reply.com/liquid-reply/en/)

## Example

The KWasm Operator allows for fine-grained control over node provisioning instead of using the node installer with a DaemonSet. This example shows how to create a KinD cluster with three nodes and install the KWasm Operator. The example provisions a single node and schedules a Wasm pod on that specific node.

```bash

# Create cluster

kind create cluster --config examples/kind/cluster.yaml

# Add helm repo

helm repo add kwasm http://kwasm.sh/kwasm-operator/

# Install operator

helm install -n kwasm --create-namespace kwasm-operator kwasm/kwasm-operator

# Annotate single node

kubectl annotate node kind-worker2 kwasm.sh/kwasm-node=true

# Run example

kubectl apply -f examples/kind/runtimeclass.yaml

kubectl apply -f examples/kind/pod.yaml

```

## Troubleshoot

`Version v3.8.7 does not exist or is not available for darwin/arm64.`

```bash

export KUSTOMIZE_VERSION=v4.5.7

make install run

```
