How to build and run SpinApp on Azure Kubernetes Services (AKS) with SpinKube in 3 steps

This tutorial guides you to run SpinApp on AKS with SpinKube in just 3 simple steps.

Let's get started.

Step 1: Create AKS cluster

az login --use-device-code
az account set --subscription <your subscription id>
az account show

Now you are ready to create the AKS cluster as below:

az group create --name globalazure24 --location southeastasia

az aks create \
  --resource-group globalazure24 \
  --name spinkube-aks \
  --node-count 1
  --generate-ssh-keys

az aks get-credentials --resource-group globalazure24 --name spinkube-aks

Step 2: Install Spinkube on AKS

# SpinKube needs cert-manager for provisioning and managing TLS certificates that are used by the admission webhook system of the Spin Operator
kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.4/cert-manager.crds.yaml

# Add Helm repositories jetstack and KWasm
helm repo add jetstack https://charts.jetstack.io
helm repo add kwasm http://kwasm.sh/kwasm-operator

# Update Helm repositories
helm repo update

# Install cert-manager using Helm
helm install \
  cert-manager jetstack/cert-manager \
  --namespace cert-manager \
  --create-namespace \
  --version v1.14.4

# Install KWasm operator
helm install \
  kwasm-operator kwasm/kwasm-operator \
  --namespace kwasm \
  --create-namespace \
  --set kwasmOperator.installerImage=ghcr.io/spinkube/containerd-shim-spin/node-installer:v0.13.1

# For demo, making all nodes can run wasm workload, kwasm-operator will create containerd-shim-spin on these nodes 
kubectl annotate node --all kwasm.sh/kwasm-node=true

kubectl apply -f https://github.com/spinkube/spin-operator/releases/download/v0.1.0/spin-operator.runtime-class.yaml

kubectl apply -f https://github.com/spinkube/spin-operator/releases/download/v0.1.0/spin-operator.crds.yaml

kubectl apply -f https://github.com/spinkube/spin-operator/releases/download/v0.1.0/spin-operator.shim-executor.yaml

Step 3: Build and run SpinApp on AKS

git clone https://github.com/thangchung/coffeeshop-on-spinkube

git checkout feat/global-azure-2024

cd coffeeshop-on-spinkube/product-api

export IMAGE_NAME=ttl.sh/coffeeshop-product-api-spin:24h

spin registry push --build $IMAGE_NAME

spin kube scaffold -f $IMAGE_NAME > app.yaml

kubectl apply -f app.yaml

Now you're ready to curl:

curl http://localhost/v1-get-items-by-types/1,2,3 | jq .
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   280    0   280    0     0   2788      0 --:--:-- --:--:-- --:--:--  2800
[
  {
    "image": "img/COFFEE_BLACK.png",
    "item_type": "CoffeeBlack",
    "name": "COFFEE_BLACK",
    "price": 3
  },
  {
    "image": "img/COFFEE_WITH_ROOM.png",
    "item_type": "CoffeeWithRoom",
    "name": "COFFEE_WITH_ROOM",
    "price": 3
  },
  {
    "image": "img/ESPRESSO.png",
    "item_type": "Espresso",
    "name": "ESPRESSO",
    "price": 3.5
  }
]

Happy hacking SpinKube on AKS!
