Deploy Wordpress to a Tanzu Kubernetes Cluster by Using Helm and kubectl for Developer Ready Infrastructure for VMware Cloud Foundation

You deploy the second application, a Wordpress blog to your Tanzu Kubernetes cluster by using Helm and kubectl.

Procedure

1. Log in to the Supervisor as a vCenter Single Sign-On Administrator user.

   kubectl vsphere login --server supervisor_cluster_IP_address --TanzuKubernetesCluster tanzu_Kubernetes_cluster_name --TanzuKubernetesClusterNamespace tanzu_kubernetes_cluster_namespace --vsphere-username supervisor_cluster_administrator

2. Switch the kubectl context to the Tanzu Kubernetes cluster.

   kubectl config set-context tanzu_kubernetes_cluster_name

3. Create a wordpress namespace.

   kubectl create namespace wordpress 

4. Add the Bitnami repository for Helm charts.

   helm repo add bitnami https://charts.bitnami.com/bitnami

5. Update your local cache with the Bitnami repository details.

   helm repo update

6. Search for the Wordpress chart in the Bitnami repository.

   helm search repo bitnami/wordpress

   You get a return value for the Wordpress chart similar to that output.

   helm search repo bitnami/wordpress
   
   NAME                    CHART VERSION   APP VERSION     DESCRIPTION
   bitnami/wordpress       10.10.8         5.7.1           Web publishing platform for building blogs and ...

7. Deploy Wordpress by using Helm CLI.

   helm install sfo-w01-tkc01-wp01 --version version --namespace wordpress --set global.storageClass=vsphere-with-tanzu-storage-policy --set wordpressBlogName="Wordpress Instance"  --set  wordpressUsername=wp-admin --set wordpressPassword=wp-admin_password bitnami/wordpress

8. Find the load balancer external IP address for the Wordpress service.

   kubectl get svc --namespace wordpress sfo-w01-tkc01-wp01-wordpress --template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}"

9. After the deployment completes, open a Web browser and enter the load balancer IP from the previous step.

A new browser window or tab opens with the "WORDPRESS INSTANCE" heading and with the "Just another Wordpress site" subheading. This is the Web interface for your new Wordpress website.
