Preparing the WDT Create Domain YAML File

7.2.3 Preparing the WDT Create Domain YAML File

Prepare the create-domain-wdt.yaml file by running the following commands:

Navigate to the $WORKDIR/kubernetes/create-access-domain/domain-home-on-pv/wdt-utils/generate_models_utils directory:
```
cd $WORKDIR/kubernetes/create-access-domain/domain-home-on-pv/wdt-utils/generate_models_utils
```

Make a copy of the create-domain-wdt.yaml file:

cp create-domain-wdt.yaml create-domain-wdt.yaml.orig

Edit the create-domain-wdt.yaml and modify the following parameters. Save the file when complete:

appVersion: 14c
domainUID: <domain_uid>
domainHome: /u01/oracle/user_projects/domains/<domain_uid>
image: <image_name>:<tag>
imagePullSecretName: <container_registry_secret>
logHome: /u01/oracle/user_projects/domains/logs/<domain_uid>
namespace: <domain_namespace>
weblogicDomainStorageType: NFS
weblogicDomainStorageNFSServer: <nfs_server>
weblogicDomainStoragePath: <physical_path_of_persistent_storage>
weblogicDomainStorageSize: 10Gi

For example:

appVersion: 14c
domainUID: accessdomain
domainHome: /u01/oracle/user_projects/domains/accessdomain
image: container-registry.oracle.com/middleware/oam_cpu:14.1.2.1.0-jdk17-ol8-<YYMMDD>
imagePullSecretName: orclcred
logHome: /u01/oracle/user_projects/domains/logs/accessdomain
namespace: oamns
weblogicDomainStorageType: NFS
weblogicDomainStorageNFSServer: mynfsserver
weblogicDomainStoragePath: /nfs_volumes/oam/accessdomainpv
weblogicDomainStorageSize: 10Gi

Note:

If using a shared file system instead of NFS, set weblogicDomainStorageType: HOST_PATH and remove weblogicDomainStorageNFSServer.

A full list of parameters in the create-domain-wdt.yaml file are shown below:

Parameter	Definition	Default
adminPort	Port number for the Administration Server inside the Kubernetes cluster.	7001
adminNodePort	Port number of the Administration Server outside the Kubernetes cluster.	30701
configuredManagedServerCount	Number of Managed Server instances to generate for the domain.	5
datasourceType	Type of JDBC datasource applicable for the OAM domain. Legal values are `agl` and `generic`. Choose `agl` for Active GridLink datasource and `generic` for Generic datasource. For enterprise deployments, Oracle recommends that you use GridLink data sources to connect to Oracle RAC databases. See the Preparing an Existing Database for an Enterprise Deployment for further details.	generic
domainHome	Home directory of the OAM domain. If not specified, the value is derived from the `domainUID` as `/shared/domains/<domainUID>`.	/u01/oracle/user_projects/domains/accessdomain
domainPVMountPath	Mount path of the domain persistent volume.	/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.	accessdomain
edgInstall	Used only if performing an install using the Enterprise Deployment Guide. See, Enterprise Deployment Guide for Oracle Identity and Access Management in a Kubernetes Cluster	false
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.	true
image	OAM container image. The operator requires OAM 14.1.2. Refer to Obtaining the OAM Container image for details on how to obtain or create the image.	oracle/oam:14.1.2.1.0
imagePullSecretName	Name of the Kubernetes secret to access the container registry to pull the OAM container image. The presence of the secret will be validated when this parameter is specified.	orclcred
initialManagedServerReplicas	Number of Managed Servers to initially start for the domain.	2
javaOptions	Java options for starting the Administration Server and Managed Servers. A Java option can have 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. If not specified, the value is derived from the `domainUID` as `/shared/logs/<domainUID>`.	/u01/oracle/user_projects/domains/logs/accessdomain
namespace	Kubernetes namespace in which to create the domain.	oamns
oamCPU	Initial CPU Units, 1000m = 1 CPU core.	1000m
oamMaxCPU	Max CPU a pod is allowed to consume.	2
oamMemory	Initial memory allocated to a pod.	4Gi
oamMaxMemory	Max memory a pod is allowed to consume.	8Gi
oamServerJavaParams	The memory parameters to use for the OAM managed servers.	"-Xms8192m -Xmx8192m"
productionModeEnabled	Boolean indicating if production mode is enabled for the domain.	true
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
weblogicDomainStorageType	Persistent volume storage type. Options are `NFS` for `NFS` volumes or `HOST_PATH` for shared file system.	NFS
weblogicDomainStorageNFSServer	Hostname or IP address of the NFS Server.	nfsServer
weblogicDomainStoragePath	Physical path to the persistent volume.	/scratch/accessdomainpv
weblogicDomainStorageSize	Total storage allocated to the persistent storage.	10Gi

Note:

The above CPU and memory values are for examples only. For Enterprise Deployments, please review the performance recommendations and sizing requirements in Enterprise Deployment Guide for Oracle Identity and Access Management in a Kubernetes Cluster.
