This document details on how to use sample scripts to demonstrate the creation of a WebCenter Sites domain home on an existing Kubernetes persistent volume (PV) and persistent volume claim (PVC). The scripts also generate the domain YAML file, which can then be used to start the Kubernetes artifacts of the corresponding domain.
If required, domain creation inputs can be customized by editing create-domain-inputs.yaml as described below:
Please note that the sample scripts for the WebCenter Sites domain deployment are available from the previously downloaded repository at kubernetes/create-wcsites-domain/domain-home-on-pv/.
Make a copy of the create-domain-inputs.yaml file before updating the default values.
The default domain created by the script has the following characteristics:
AdminServer listening on port 7001.wcsites_cluster of size 5.wcsites_server1, listening on port 8001./shared/logs/<domainUID>.The following parameters can be provided in the inputs file:
| Parameter | Definition | Default |
|---|---|---|
adminPort |
Port number for the Administration Server inside the Kubernetes cluster. | 7001 |
adminServerName |
Name of the Administration Server. | AdminServer |
clusterName |
Name of the WebLogic cluster instance to generate for the domain. By default the cluster name is wcsites_cluster for the WebCenter Sites domain. |
wcsites_cluster |
configuredManagedServerCount |
Number of Managed Server instances for the domain. | 3 |
createDomainFilesDir |
Directory on the host machine to locate all the files that you need to create a WebLogic domain, including the script that is specified in the createDomainScriptName property. By default, this directory is set to the relative path wlst, and the create script will use the built-in WLST offline scripts in the wlst directory to create the WebLogic domain. An absolute path is also supported to point to an arbitrary directory in the file system. The built-in scripts can be replaced by the user-provided scripts or model files as long as those files are in the specified directory. Files in this directory are put into a Kubernetes config map, which in turn is mounted to the createDomainScriptsMountPath, so that the Kubernetes pod can use the scripts and supporting files to create a domain home. |
wlst |
createDomainScriptsMountPath |
Mount path where the create domain scripts are located inside a pod. The create-domain.sh script creates a Kubernetes job to run the script (specified in the createDomainScriptName property) in a Kubernetes pod to create a domain home. Files in the createDomainFilesDir directory are mounted to this location in the pod, so that the Kubernetes pod can use the scripts and supporting files to create a domain home. |
/u01/weblogic |
createDomainScriptName |
Script that the create domain script uses to create a WebLogic domain. The create-domain.sh script creates a Kubernetes job to run this script to create a domain home. The script is located in the in-pod directory that is specified in the createDomainScriptsMountPath property. If you need to provide your own scripts to create the domain home, instead of using the built-it scripts, you must use this property to set the name of the script that you want the create domain job to run. |
create-domain-job.sh |
domainHome |
Home directory of the WebCenter Sites domain. This field cannot be modified. |
/u01/oracle/user_projects/domains/wcsitesinfra |
domainPVMountPath |
Mount path of the domain persistent volume. This field cannot be modified. |
/u01/oracle/user_projects/domains |
domainUID |
Unique ID that will be used to identify this particular domain. Used as the name of the generated WebLogic domain as well as the name of the Kubernetes domain resource. This ID must be unique across all domains in a Kubernetes cluster. This ID cannot contain any character that is not valid in a Kubernetes service name. | wcsitesinfra |
exposeAdminNodePort |
Boolean indicating if the Administration Server is exposed outside of the Kubernetes cluster. | false |
exposeAdminT3Channel |
Boolean indicating if the T3 administrative channel is exposed outside the Kubernetes cluster. | false |
image |
WebCenter Sites Docker image. The Operator requires WebCenter Sites release 12.2.1.4.0. Refer to WebCenter Sites Docker image for details on how to obtain or create the image. | oracle/wcsites:12.2.1.4 |
imagePullPolicy |
WebLogic Docker image pull policy. Legal values are IfNotPresent, Always, or Never |
IfNotPresent |
imagePullSecretName |
Name of the Kubernetes secret to access the Docker Store to pull the WebLogic Server Docker image. The presence of the secret will be validated when this parameter is specified. | |
includeServerOutInPodLog |
Boolean indicating whether to include the server.out to the pod’s stdout. | true |
initialManagedServerReplicas |
Number of Managed Server to initially start for the domain. | 1 |
javaOptions |
Java options for starting the Administration Server and Managed Servers. A Java option can include references to one or more of the following pre-defined variables to obtain WebLogic domain information: $(DOMAIN_NAME), $(DOMAIN_HOME), $(ADMIN_NAME), $(ADMIN_PORT), and $(SERVER_NAME). |
-Dweblogic.StdoutDebugEnabled=false |
logHome |
The in-pod location for the domain log, server logs, server out, and Node Manager log files. This field cannot be modified. |
/u01/oracle/user_projects/logs/wcsitesinfra |
managedServerNameBase |
Base string used to generate Managed Server names. | wcsites_server |
managedServerPort |
Port number for each Managed Server. | 8001 |
namespace |
Kubernetes namespace in which to create the domain. | wcsites-ns |
persistentVolumeClaimName |
Name of the persistent volume claim created to host the domain home. If not specified, the value is derived from the domainUID as <domainUID>-weblogic-sample-pvc. |
wcsitesinfra-domain-pvc |
productionModeEnabled |
Boolean indicating if production mode is enabled for the domain. | true |
serverStartPolicy |
Determines which WebLogic Server instances will be started. Legal values are NEVER, IF_NEEDED, ADMIN_ONLY. |
IF_NEEDED |
t3ChannelPort |
Port for the T3 channel of the NetworkAccessPoint. | 30012 |
t3PublicAddress |
Public address for the T3 channel. This should be set to the public address of the Kubernetes cluster. This would typically be a load balancer address. For development environments only: In a single server (all-in-one) Kubernetes deployment, this may be set to the address of the master, or at the very least, it must be set to the address of one of the worker nodes. | If not provided, the script will attempt to set it to the IP address of the Kubernetes cluster. |
weblogicCredentialsSecretName |
Name of the Kubernetes secret for the Administration Server’s user name and password. If not specified, then the value is derived from the domainUID as <domainUID>-weblogic-credentials. |

You can form the names of the Kubernetes resources in the generated YAML files with the value of these properties
specified in the create-domain-inputs.yaml file: adminServerName , clusterName and managedServerNameBase . Characters that are invalid in a Kubernetes service name are converted to valid values in the
generated YAML files. For example, an uppercase letter is converted to a lowercase letter and an underscore ("_") is converted to a
hyphen ("-") .
The sample demonstrates how to create a WebCenter Sites domain home and associated Kubernetes resources for a domain that has one cluster only. In addition, the sample provides the capability for users to supply their own scripts to create the domain home for other use cases. You can modify the generated domain YAML file to include more use cases.
Understanding the syntax of the create-domain.sh script:
$ ./create-domain.sh \
-i create-domain-inputs.yaml \
-o /<path to output-directory>
The script performs the following functions:
Creates a directory for the generated Kubernetes YAML files for this domain if it does not
already exist. The path name is /<path to output-directory>/weblogic-domains/<domainUID>.
If the directory already exists, remove its content before using this script.
Creates a Kubernetes job that will start up a utility WebCenter Sites container and run offline WLST scripts to create the domain on the shared storage.
Runs and waits for the job to finish.
Creates a Kubernetes domain YAML file, domain.yaml, in the directory that is created above.
This YAML file can be used to create the Kubernetes resource using the kubectl create -f
or kubectl apply -f command:
$ kubectl apply -f ../<path to output-directory>/weblogic-domains/<domainUID>/domain.yaml
Creates a convenient utility script, delete-domain-job.yaml, to clean up the domain home
created by the create script.
Now, run the create-domain.sh sample script below, pointing it at the create-domain-inputs inputs file and an output directory like below:
bash-4.2$ rm -rf kubernetes/create-wcsites-domain/output/weblogic-domains
bash-4.2$ sh kubernetes/create-wcsites-domain/domain-home-on-pv/create-domain.sh \
-i kubernetes/create-wcsites-domain/domain-home-on-pv/create-domain-inputs.yaml \
-o kubernetes/create-wcsites-domain/output

To see the Admin and Managed Servers logs, you can check the pod logs:
$ kubectl logs -f wcsitesinfra-adminserver -n wcsites-ns
$ kubectl exec -it wcsitesinfra-adminserver -n wcsites-ns -- /bin/bash
$ kubectl logs -f wcsitesinfra-wcsites-server1 -n wcsites-ns
$ kubectl exec -it wcsitesinfra-wcsites-server1 -n wcsites-ns -- /bin/bash
Use the following command to see the pods running the servers:
$ kubectl get pods -n NAMESPACE
Here is an example of the output of this command:
-bash-4.2$ kubectl get pods -n wcsites-ns
NAME READY STATUS RESTARTS AGE
wcsitesinfra-adminserver 1/1 Running 0 56m
wcsitesinfra-create-fmw-infra-sample-domain-job-rq4xv 0/1 Completed 0 65m
wcsitesinfra-wcsites-server1 1/1 Running 0 41m
Use the following command to see the services for the domain:
$ kubectl get services -n NAMESPACE
Here is an example of the output of this command:
-bash-4.2$ kubectl get services -n wcsites-ns
NAME READY STATUS RESTARTS AGE
wcsitesinfra-adminserver 1/1 Running 0 7m38s

Below are the default values for exposing services required for all the WebCenter Sites Managed Servers. Reset them if any values are modified.
Details on kubernetes/create-wcsites-domain/utils/wcs-services.yaml:
Execute the below command for exposing the services: (If domain is configured for more than 3 Managed Servers then add the service yaml for additional servers.)
$ kubectl apply -f kubernetes/create-wcsites-domain/utils/wcs-services.yaml
service/wcsitesinfra-wcsites-server1-np created
service/wcsitesinfra-wcsites-server1-svc created
service/wcsitesinfra-wcsites-server2-svc created

You can choose a load balancer provider for your WebLogic domains running in a Kubernetes cluster. Please refer to the WebLogic Kubernetes Operator Load Balancer Samples for information about the current capabilities and setup instructions for each of the supported load balancers.
For information on how to set up Loadbalancer for setting up WebCenter Sites domain on K8S:
For Traefik, see Setting Up Loadbalancer Traefik for the WebCenter Sites Domain on K8S
For Nginx, see Setting Up Loadbalancer Nginx for the WebCenter Sites Domain on K8S
Configure WebCenter Sites by hitting url http://${LOADBALANCER-HOSTNAME}:${LOADBALANCER-PORT}/sites/sitesconfigsetup
When installing, select sample sites to be installed and enter the required passwords. Do not change the sites-config location. If you change the location, installation will fail.
After the configuration is complete, edit the domain, and restart the Managed Server.
To stop Managed Servers:
$ kubectl patch domain wcsitesinfra -n wcsites-ns --type='json' -p='[{"op": "replace", "path": "/spec/clusters/0/replicas", "value": 0 }]'
To start all configured Managed Servers:
$ kubectl patch domain wcsitesinfra -n wcsites-ns --type='json' -p='[{"op": "replace", "path": "/spec/clusters/0/replicas", "value": 3 }]'
-bash-4.2$ kubectl get pods -n wcsites-ns -w

Incase of Nginx Load Balancer: Use Property Management Tool and update cookieserver.validnames property with value JSESSIONID,stickyid.
While configuring publishing destination use NodePort port of target cluster which can be found by executing below command:
(In this example for publishihng the port 30155 has to be used.)
-bash-4.2$ kubectl get service/wcsitesinfra-wcsites-server1-np -n wcsites-ns
