**For Mac users:**
``` bash
export SERVICE_IP=$(kubectl get svc --namespace default wordpress-wordpress -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
echo http://$SERVICE_IP/admin
echo Username: user
echo Password: $(kubectl get secret --namespace default wordpress-wordpress -o jsonpath='{.data.wordpress-password}' | base64 --decode)
Open the browser and navigate to the URL from console output.
For Windows users:
- Run the following commands to get hostname and password:
kubectl get svc --namespace default wordpress-wordpress -o jsonpath='{.status.loadBalancer.ingress[0].ip}'
kubectl get secret --namespace default wordpress-wordpress -o jsonpath='{.data.wordpress-password}
- Open browser to http://%hostname%/admin, where %hostname% is the hostname you got from the kubectl
- Decode admin password with https://www.base64decode.org/
Congrats! You just deployed your first app in a Kubernetes cluster with Kublr.
