NOTES:

CHART NAME: wordpress

CHART VERSION: 15.0.1

APP VERSION: 6.0.0

** Please be patient while the chart is being deployed **

Your WordPress site can be accessed through the following DNS name from within your cluster:

understood-zebu-wordpress.wordpress-cwi.svc.cluster.local (port 80)

To access your WordPress site from outside the cluster follow the steps below:

1. Get the WordPress URL by running these commands:

NOTE: It may take a few minutes for the LoadBalancer IP to be available.

Watch the status with: 'kubectl get svc --namespace wordpress-cwi -w understood-zebu-wordpress'

export SERVICE_IP=$(kubectl get svc --namespace wordpress-cwi understood-zebu-wordpress --include "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}")

echo "WordPress URL: http://$SERVICE_IP/"

echo "WordPress Admin URL: http://$SERVICE_IP/admin"

2. Open a browser and access WordPress using the obtained URL.

3. Login with the following credentials below to see your blog:

echo Username: user

echo Password: $(kubectl get secret --namespace wordpress-cwi understood-zebu-wordpress -o jsonpath="{.data.wordpress-password}" | base64 -d)
