Update and Adaptation

Application configuration items include image address, Service, and storage disk mounting. Update and make adaptation based on the live environment.

In this example, update the WordPress service.

  1. On the ELB console, buy an elastic load balancer.
  2. Record the ELB ID and the corresponding subnet ID.
  3. Log in to the CCE console, choose Resource Management > Network and find the WordPress service. Add the following annotations to its YAML file: 

    annotations: 
  kubernetes.io/elb.class: union 
  kubernetes.io/elb.id: 9d06a39d-12e1-4ada-835d-c204397498a3 
  kubernetes.io/elb.subnet-id: f86ba71c-beb2-46e1-8910-39c8a7d4bb36 
  kubernetes.io/session-affinity-mode: SOURCE_IP

If the image of your application fails to be pulled, edit the YAML file on the workload page of the CCE console. Set the image address to the repository address obtained from the SWR console.
