+# Input Yaml to the test
 
+The input yaml file(for example, domainonpvwlst.yaml) to the java test is used to override any or all the attributes in
+- samples domain inputs - click [here](https://github.com/oracle/weblogic-kubernetes-operator/blob/develop/kubernetes/samples/scripts/create-weblogic-domain/domain-home-on-pv/create-domain-inputs.yaml) to see samples create-domain-inputs file

+- load balancer attributes and
+- custom attributes that are used to provide more flexibility for creating the domain.
+
+Below are the load balancer attributes:
+- loadBalancer: value can be TRAEFIK or VOYAGER, default is TRAEFIK
+- loadBalancerWebPort: web port for the load balancer
+- ingressPerDomain: create ingress per domain or one ingress for all domains in multiple domain configuration, default is true. 
+
+**Note: System env variables LB_TYPE, INGRESSPERDOMAIN take precedence over the domain input attributes. These variables apply for the entire run, not just one domain.**
+
+Below are the custom attributes:
+- createDomainPyScript is used to provide a custom create-domain.py script for domain on pv using WLST or create-wls-domain.py for domain in image 
+- clusterType is used to create a CONFIGURED or DYNAMIC Cluster. This is supported for domain on pv using WLST or domain in image using WDT configurations. Default is DYNAMIC
