Container Service for Kubernetes:Use ACK to quickly deploy a magic cube game application

1. Quickly create a cluster

If you want to quickly create an ACK cluster, you can use default settings for the cluster parameters. If you want to create a cluster in the production environment, refer to Create an ACK managed cluster.

1. Log on to the ACK console. On the Clusters page, click Create Cluster.

2. In the upper part of the page, click the ACK Managed Cluster tab. Select Professional for Cluster Specification. If you need to access the cluster over the Internet, select Expose API server with EIP. Then, click Next:Node Pool Configurations in the lower-right corner of the page.

3. In the Instance Type section, select an instance type that provides 4 vCores and 8 GiB of memory, such as ecs.c6.xlarge, which belongs to the c6 compute-optimized instance family. Then, click Next:Component Configurations in the lower-right corner of the page.

4. Select ACK Cluster Monitoring Basic Edition for Monitor container. ACK Cluster Monitoring Basic Edition is free of charge. Then, click Next:Confirm Order in the lower-right corner of the page.

5. Click Create Cluster in the lower-right corner of the page.

1. Click the quick configuration link to go to the ROS console. The Create Stack page appears. In the upper part of the page, select the region where you want to create a stack. In this example, China (Hohhot) is selected. Set other parameters and click Create.

   Parameter	Description	Example
   Stack Name	You can enter a custom name.	stack_2023-06-12_cBesTX8FB
   Cluster Name	You can enter a custom name. Note You cannot specify the name of an existing cluster.	ack-demo-cube
   VSwitch Available Zone	Select a zone.	Zone A
   Instance Type	Select an instance family. You can filter instance types by the number of vCores and memory size. You can also set the Architecture and Type parameters to filter instance types.	General-purpose Type g6
   Worker System Disk Category	Select a system disk type for nodes. The available disk types vary based on the instance type that you select. For more information about the disk types supported by different instance types, see Overview of instance families. Disk types not displayed in the drop-down list are not supported by the instance types that you select.	cloud_essd
   Instance Password	Enter a password that is used to log on to the nodes.	Enter a password.

• If Created is displayed in the Status parameter on the Stack Information tab, the stack is created.

• If Created is not displayed in the Status parameter on the Stack Information tab, the stack is not created. You can click Quick Diagnostics to view the diagnostic details.

2. Test access to the application.

   Wait until Created is displayed in the Status parameter on the Stack Information tab. Then, click the Outputs tab on the right of the Stack Information tab. Click the hyperlink next to CubeAddress to start the magic cube game.

5. Click Create Cluster in the lower-right corner of the page.

2. Connect to the cluster

You can use kubectl, Workbench, or Cloud Shell to connect to the cluster.

3. Deploy and expose an application

This step shows how to use kubectl to deploy a stateless application by creating a Deployment and how to use a LoadBalancer Service to expose the application. For more information about how to expose an application, see Use an automatically created SLB instance to expose an application.

1. Use the following YAML template to create an ack-cube.yaml file:

   apiVersion: apps/v1 # for versions before 1.8.0 use apps/v1beta1
   kind: Deployment
   metadata:
     name: ack-cube # The name of the application. 
     labels:
       app: ack-cube
   spec:
     replicas: 2 # The number of pod replicas. 
     selector:
       matchLabels:
         app: ack-cube  # You must specify the same value for the selector of the Service that is used to expose the application. 
     template:
       metadata:
         labels:
           app: ack-cube
       spec:
         containers:
         - name: ack-cube
           image: registry.cn-hangzhou.aliyuncs.com/acr-toolkit/ack-cube:1.0 # Replace the value with the address of the image that you want to use in the <image_name:tags> format. 
           ports:
           - containerPort: 80 # The container port that you want to expose. 
           resources:
             limits: # The resource limits. 
               cpu: '1'
               memory: 1Gi
             requests: # The resource requests.
               cpu: 500m
               memory: 512Mi        

2. Run the following command to deploy the ack-cube application:

   kubectl apply -f ack-cube.yaml

3. Run the following command to query the status of the application:

   kubectl get deployment ack-cube

   Expected output:

   NAME       READY   UP-TO-DATE   AVAILABLE   AGE
   ack-cube   2/2     2            2           96s

4. Use the following YAML template to create an ack-cube-svc.yaml file. Set selector to the value of matchLabels in the ack-cube.yaml file. In this example, the value is app: ack-cube. This adds the application to the backend of the Service.

   apiVersion: v1
   kind: Service
   metadata:
     labels:
       app: ack-cube
     name: ack-cube-svc
     namespace: default
   spec:
     ports:
     - port: 80
       protocol: TCP
       targetPort: 80
     selector:
       app: ack-cube # You must specify the value of the matchLabels parameter in the YAML file that is used to create the Deployment. 
     type: LoadBalancer

5. Run the following command to create a Service named ack-cube-svc and use the Service to expose the application.

   ACK automatically creates an Internet-facing SLB instance and associates the instance with the Service.

   kubectl apply -f ack-cube-svc.yaml

6. Run the following command to verify that the LoadBalancer Service is created:

   The application that you created is exposed by using the IP address in the EXTERNAL-IP column in the output.

   kubectl get svc ack-cube-svc

   Expected output:

   NAME           TYPE           CLUSTER-IP      EXTERNAL-IP     PORT(S)        AGE
   ack-cube-svc   LoadBalancer   172.16.72.161   47.94.xx.xx   80:31547/TCP   32s
