Create a Windows application

This section describes how to use an orchestration template to create a web application that consists of a Deployment and a Service. The Deployment provisions pods for the application and the Service manages access to the pods at the backend.

1. Log on to the ACK console.
2. In the left-side navigation pane of the ACK console, click Clusters.
3. On the Clusters page, find the cluster that you want to manage and click the name of the cluster or click Details in the Actions column. The details page of the cluster appears.
4. In the left-side navigation pane of the details page, choose Workloads > Deployments.
5. On the Deployments page, click Create from YAML in the upper-right corner.
6. Set the parameters and click Create.
   • Namespace: Select the namespace to which the resource objects belong. By default, the default namespace is selected. Most resources are scoped to namespaces, except for underlying computing resources, such as nodes and persistent volumes (PVs).
   • Sample Template: ACK provides YAML templates of various resource types. This simplifies the deployment of resource objects. You can also create a custom template based on YAML syntax to define the resources that you want to create.
   • Add Deployment: This feature allows you to define a YAML template.
   • Use Existing Template: You can import an existing template to the configuration page.
   • Save As: You can save the template that you have configured.

   

   The following sample template is based on an orchestration template provided by ACK. You can use this template to create a Deployment to run a web application.

   Note ACK supports YAML syntax. You can use the --- symbol to separate multiple resource objects. This allows you to create multiple resource objects in a single template.

   apiVersion: v1
   kind: Service
   metadata:
     labels:
       app: web-windows
     name: web-windows
   spec:
     type: LoadBalancer
     ports:
       - port: 80
         protocol: TCP
         targetPort: 80
     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 following image address with the ID of the region where the cluster is deployed. 
           - image: registry-vpc.cn-hangzhou.aliyuncs.com/acs/sample-web-windows:v1.0.1
             name: windows
             ports:
             - containerPort: 80
               protocol: TCP

   Note

   • The registry-vpc.{region}.aliyuncs.com/acs/sample-web-windows image provided by Container Registry is a sample web application image based on Windows. This image is based on mcr.microsoft.com/windows/nanoserver.
   • You can also use the sample ASP.NET application image provided by Microsoft: mcr.microsoft.com/dotnet/samples:aspnetapp. For more information, see .NET Samples.
7. Click Create. A notification that indicates the deployment status appears. After the Deployment is deployed, you can view the Deployment on the Deployments page.
8. Access the web application
   1. In the left-side navigation pane of the ACK console, click Clusters.
   2. On the Clusters page, find the cluster that you want to manage and click the name of the cluster or click Details in the Actions column. The details page of the cluster appears.
   3. In the left-side navigation pane of the details page, choose Network > Services.
   4. On the Services page, you can find that the web-windows Service is deployed and exposed through an external endpoint.
   5. Click the external endpoint of the web-windows Service to access the web application.
   6. To view the hostname of the application containers, change the URL to name.html.
