Create a Windows application - Container Service for Kubernetes

This example shows how to use an orchestration template to create a web application that contains a Deployment and a Service, and schedule it to run on a Windows node.

Prerequisites

Your cluster has a Windows node. For more information, see Create and manage a Windows node pool.

Step 1: Deploy the sample application

Follow these steps to deploy a sample ASP.NET application to a Windows node in your cluster. A Service automatically creates a Server Load Balancer instance to expose port 80 of the application, which makes the web application accessible from the Internet.

Log on to the ACK console. In the left navigation pane, click Clusters.
On the Clusters page, find the cluster you want to manage and click its name. In the left navigation pane, choose Workloads > Deployments.

Click Create From YAML and set Sample Template to Custom. Then, enter the YAML content and click Submit.

The following YAML code defines an ASP.NET web application. The application is scheduled to run on a Windows node and is exposed by a Service of the LoadBalancer type.

apiVersion: v1
kind: Service
metadata:
  labels:
    app: web-windows
  name: web-windows
spec:
  type: LoadBalancer
  ports:
    - port: 80
      protocol: TCP
      targetPort: 8080
  selector:
    app: web-windows
---
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: web-windows
  name: web-windows
spec:
  selector:
    matchLabels:
      app: web-windows
  template:
    metadata:
      labels:
        app: web-windows
    spec:
      restartPolicy: Always
      terminationGracePeriodSeconds: 30
      tolerations:
      - key: os
        value: windows
      affinity:
        nodeAffinity:
          requiredDuringSchedulingIgnoredDuringExecution:
            nodeSelectorTerms:
            - matchExpressions:
              - key: kubernetes.io/os
                operator: In
                values:
                - windows
      containers:
  # Replace <cn-hangzhou> in the image address with the actual region of your cluster.
        - image: registry-cn-hangzhou-vpc.ack.aliyuncs.com/acs/dotnet-samples:aspnetapp
          name: windows
          ports:
          - containerPort: 8080
            protocol: TCP

After submission, you are returned to the Deployments page, where the new web application appears in the list.

Step 2: Access the application

On the Clusters page, find the cluster you want and click its name. In the left-side pane, choose Network > Services.
Click the name of the target Service (web-windows). Then, in the Basic Information section, click External IP to access the web application.
