Container Service for Kubernetes:Deploy a WordPress application by using Helm

Prerequisites

• The CSI plug-in is installed in the cluster and runs as expected. For more information, see Manage the CSI plug-in.

• Obtain the kubeconfig file of a cluster and use kubectl to connect to the cluster.

Step 1: Deploy the WordPress application

1. Log on to the ACK console. In the left-side navigation pane, click Clusters.

2. On the Clusters page, find the cluster that you want to manage and click its name. In the left-side navigation pane, choose Applications > Helm.

3. On the Helm page, click Deploy. In the Basic Information step, configure the parameters based on the following table.

   Parameter	Example
   Application Name	wordpress
   Namespace	default
   Source	Marketplace
   Chart	Use Scenarios: Select All. Supported Architecture: Select amd64. Search box: Search for ack-wordpress-sample.

   Select ack-wordpress-sample, and click Next.

4. In the Parameters step, configure the Chart Version parameter and click OK.

Step 2: Access the WordPress application

1. After WordPress is installed, run the following command to query the external IP address EXTERNAL-IP:

   kubectl get svc --namespace default 

   The expected output is as follows, where EXTERNAL-IP is 118.xx.xx.10.

   NAME                                TYPE           CLUSTER-IP      EXTERNAL-IP      PORT(S)                      AGE
   wordpressabc-ack-wordpress-sample   LoadBalancer   172.16.86.22    118.190.xx.xx   80:30837/TCP,443:32433/TCP   33m
   wordpressabc-mariadb                ClusterIP      172.16.70.108   <none>           3306/TCP                     33m

2. Use the kubectl get pod command to find the name of the WordPress pod, and then run the following command to obtain the username:

   kubectl get pod <wordpress-ack-wordpress-sample-name> -o=jsonpath='{.spec.containers[*].env[?(@.name=="WORDPRESS_USERNAME")].value}'

   Expected output:

   user

3. Run the following command to obtain the password:

   kubectl get secret --namespace default wordpress-ack-wordpress-sample -o jsonpath="{.data.wordpress-password}" | base64 --decode

   Expected output:

   ps**jRx**V

4. Enter /login into the address bar of your browser and press Enter to access WordPress. On the logon page, enter the obtained username and password to log on to the application.
