 This will create the necessary resources in the cluster, including a deployment for the Ghost app, a service for connecting to the MySQL server, and an ingress service for routing traffic to the Ghost app via the nginx-proxy with https and http.
 
 Volumes
-This configuration is using a Persistent Volume to store the Ghost blog data, this can be done by creating a persistent volume and persistent volume claim, and then referencing it in the ghost-blog-deployment.yaml file.

+# ingress-service.yaml
+In this example, $(VAR_HOST) and $(SECRET_NAME) are variables that are stored in a configMap and a Secret, respectively. These variables can be managed and updated separately from the YAML files, making it easier to update and maintain your configuration.
+
+To use variables in your YAML files, you'll first need to create a configMap and a Secret that contains the variables you need. You can do this using the kubectl command-line tool.
+
+For configMap, you can create it with the following command:
+
+Copy code
+kubectl create configmap my-config-map --from-literal=VAR_HOST=example.com
+And for Secret:
+
+Copy code
+kubectl create secret generic my-secret --from-literal=SECRET_NAME=mysecret
+Once you've created the configMap and Secret, you can reference them in your YAML files using the $(VAR_NAME) syntax.
+
+You can also manage and update the variables in the configMap and Secret using kubectl commands.
+
+It's important to note that configMap and Secret are not the only way to use variables in Kubernetes, you can also use other tools like Helm or Kustomize.
