Create a Windows application

This topic describes how to create a Windows application by using an orchestration template. In this topic, a Deployment and a Service are created to run an ASP.NET application. The Deployment provisions pods for the application and the Service allows access to application 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. In the upper-right corner of the Deployments tab, click Create from Template.
6. Set the parameters and click Create.
   • Namespace: Select the namespace to which the resource object belongs. The default namespace is default. Except for underlying computing resources such as nodes and persistent volumes (PVs), most resources are limited by namespaces.
   • 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 describe the resource that you want to define.
   • Add Deployment: This feature allows you to define a YAML template.
   • Use Existing Template: You can import an existing template to the configuration page.

   

   The following sample template is created from an orchestration template provided by ACK. This sample template provides an example on how to create a Deployment for an ASP.NET application.

   Note ACK supports YAML syntax. If you want to declare multiple resource objects in a template, you can use the --- symbol to separate the resource objects.

   apiVersion: v1
   kind: Service
   metadata:
     name: aspnet-svc
   spec:
     ports:
       - port: 80
         protocol: TCP
         targetPort: 80
     selector:
       app: aspnet
     type: LoadBalancer
   ---
   apiVersion: apps/v1
   kind: Deployment
   metadata:
     name: aspnet
   spec:
     selector:
       matchLabels:
         app: aspnet
     template:
       metadata:
         labels:
           app: aspnet
       spec:
         containers:
           - image: 'mcr.microsoft.com/dotnet/samples:aspnetapp'
             name: aspnet
         nodeSelectors:
           kubernetes.io/os: "windows"
         tolerations:
         - key: "os"
           value: "windows"

   Note The image mcr.microsoft.com/dotnet/samples:aspnetapp is a sample image provided by Microsoft. For more information, see .NET Samples.
7. Click Create. A message that indicates the deployment status appears. After the deployment is complete, you can view the Deployment on the Deployments tab.
8. Access the ASP.NET 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 a Service named aspnet-svc is created for the application. An external endpoint is also displayed on the page.
   5. Click the external endpoint of the aspnet-svc Service to access the ASP.NET application.
