Local Kubernetes cluster is running. Press Ctrl-C to shut it down.

Run WebAssembly container images in Kubernetes

Open a new terminal and run the cluster: -

  cd kubernetes && git checkout v1.22.4

export KUBERNETES_PROVIDER=local

sudo cluster/kubectl.sh config set-cluster local --server=https://localhost:6443 --certificate-authority=/var/run/kubernetes/server-ca.crt
sudo cluster/kubectl.sh config set-credentials myself --client-key=/var/run/kubernetes/client-admin.key --client-certificate=/var/run/kubernetes/client-admin.crt
sudo cluster/kubectl.sh config set-context local --cluster=local --user=myself
sudo cluster/kubectl.sh config use-context local
sudo cluster/kubectl.sh

Let’s check the status to make sure that the cluster is running.

  sudo cluster/kubectl.sh cluster-info

A WebAssembly-based HTTP service

Run the WebAssembly-based image from Docker Hub in the Kubernetes cluster as follows.

  sudo cluster/kubectl.sh run --restart=Never http-server --image=wasmedge/example-wasi-http:latest --annotations="module.wasm.image/variant=compat-smart" --overrides='{"kind":"Pod", "apiVersion":"v1", "spec": {"hostNetwork": true}}'

Since we are using hostNetwork in the kubectl run command, the HTTP server image is running on the local network with IP address 127.0.0.1. Now, you can use the curl command to access the HTTP service.

  curl -d "name=WasmEdge" -X POST http://127.0.0.1:1234

> echo: name=WasmEdge
