Pulling an Image to Deploy an Application in a CCE Cluster

Prerequisites

You have a CCE cluster that contains at least one node with 4 vCPUs and 8 GiB memory. The node is bound with an EIP.

Deploying an Application

1. Log in to the CCE console.
2. Click the name of the target cluster to access the cluster console.
3. In the navigation pane, choose Workloads. Then, click Create Workload.
4. Configure the following parameters and keep the default values for other parameters:

   Basic Info

   • Workload Type: Select Deployment.
   • Workload Name: Set it to nginx.
   • Namespace: Select default.
   • Pods: Set the quantity of pods to 1.

   Container Settings

   In the Container Information area, click Basic Info and click Select Image. In the dialog box displayed, click the Open Source Images tab, search for nginx, and select the nginx image.

   Service Settings

   Click the plus sign (+) to create a Service for accessing the workload from an external network. This example shows how to create a LoadBalancer. Configure the following parameters in the window that slides out from the right:

   • Service Name: Enter nginx. The name of the Service is exposed to external networks.
   • Service Type: Select LoadBalancer.
   • Service Affinity: Retain the default value.
   • Load Balancer: If a load balancer is available, select an existing load balancer. If not, select Auto create to create one.
   • Ports:
     • Protocol: Select TCP.
     • Service Port: In this example, set this parameter to 8080. Load balancer will use this port to create a listener and provide an entry for external traffic.
     • Container Port: listening port of the application. In this example, this parameter is set to 80. If another application is used, the container port must be the same as the listening port provided by the application.
