About Creating a Domain

Learn about the options you have when creating a domain.

• Domain Type

  A Non-JRF domain does not require an existing database.

  A JRF-enabled domain includes the Java Required Files (JRF) components and requires access to an existing database in Oracle Autonomous Database or Oracle Cloud Infrastructure Database (DB System). If using a DB System database, note that the DB System and the Kubernetes cluster must be in the same Virtual Cloud Network (VCN). See Create a Database.

• Load Balancers

  When you create a domain, Oracle WebLogic Server for OKE creates a public load balancer to distribute application traffic to the WebLogic cluster.

  The public load balancer consists of primary and standby nodes but it is accessible from a single IP address. If the primary node fails, traffic is automatically routed to the standby node. The public load balancer is configured for SSL connections (the HTTPS protocol) that terminate at the load balancer.

  The load balancers are assigned to a public subnet, for which you must specify a CIDR block if you let Oracle WebLogic Server for OKE create new subnets during stack provisioning. You must also specify shapes for the private and public load balancers.

  Note:

  By default, the reserved public IP address that you specify as the loadBalancerIP property of the LoadBalancer service in the manifest file is expected to be a resource in the same compartment as the cluster. If you want to specify a reserved public IP address in a different compartment, add the following policy to the tenancy:

  Allow any-user to read public-ips in tenancy where request.principal.type = 'cluster'
  Allow any-user to manage floating-ips in tenancy where request.principal.type = 'cluster'

  See Specifying Load Balancer Reserved Public IP Addresses.
