Create a Stack
Use Oracle WebLogic Server for OKE to create a stack that includes a basic Oracle WebLogic Server instance with network resources, Kubernetes cluster, compute instances, and private load balancers.
Launch a new stack from Marketplace.
Before you create a stack, ensure that all the prerequisites are completed. See Prerequisites to Create a Stack.
Configure WebLogic Server on Container Cluster
Specify the parameters needed to configure the WebLogic Server in a Kubernetes cluster.
Configure Verrazzano
Specify the parameters to configure Verrazzano installation based on the Verrazzano profile.
VM.Standard.E4.Flex
shape with four OCPU count
and three nodes for the WebLogic Server node pool. See Configure the Container Cluster for Verrazzano Integration.
Note:
You can configure Verrazzano installation for WebLogic Suite Edition only.When you enable Verrazzano, the default settings are:
- Free wildcard DNS service nip.io
- Self-signed CA certificate
- Flexible shape with minimum bandwidth size of 10 Mbps and maximum bandwidth of 100 Mbps for Administrative load balancer and Application Load Balancer
- Three master replicas (with 50Gi storage) and two data replicas (with 50Gi storage) for OpenSearch for prod profile, and one master replica (with 50Gi storage) and one data replica (with 50Gi storage) for OpenSearch for dev profile
- 50 Gi persistent volume storage for the components, OpenSearch, Prometheus, Grafana, and Keycloak
To configure Verrazzano:
Add a DNS view to the DNS Resolver
When you configure Verrazzano installation for your Oracle WebLogic Server for OKE stack using a private DNS zone and an existing VCN, you need to configure the DNS resolver of the VCN to use the DNS view of the DNS zone.
- Sign in to the Oracle Cloud Infrastructure Console.
- From the navigation menu, click Networking, and then select Virtual Cloud Networks.
- From the list of Virtual Cloud Networks, click the name of the VCN.
- On the VCN Information tab, click the name of the DNS Resolver for the VCN.
- From the Associated Private Views section, click Manage Private Views.
- In the Private Manage Views window,
select the Private View from the compartment where
the private view of the private DNS zone is located.
If a Private View is already associated with the resolver, click Additional Private View to select the private view of the private DNS zone.
- Click Save Changes.
Configure the Network
Define the Virtual Cloud Network (VCN) and the subnets configuration for the stack.
Configure the Container Cluster
You can specify the parameters needed to create a container cluster or configure the WebLogic Server domain to use an existing container cluster for an existing VCN and an existing subnet only.
Note:
If you configure Verrazzano installation, then to configure the container cluster, see Configure the Container Cluster with Verrazzano.Configure the Administration Instances
Specify where you want to create the administration instances and select the shapes to use.
Configure the Registry
Specify the credentials that Oracle WebLogic Server for OKE uses to access container images in the Oracle Cloud Infrastructure Registry (OCIR).
For information about how to create a container registry, see Overview of Registry in the Oracle Cloud Infrastructure documentation.
Create OCI Policies
When you create stack, by default the OCI Policies check box is selected and Oracle WebLogic Server for OKE creates a dynamic group and relevant root-level (tenancy) policies for you.
If you are not an administrator, the necessary groups and policies must be in place before you can create a stack.
Before you deselect the check box, ask your administrator to create the required dynamic group and relevant policies, as described in Create a Dynamic Group and Create Policies for the Dynamic Group.
Create the Stack
After you have specified the parameters for your stack, finish creating the stack.
On the Review page of the Create Stack wizard, review the information you have provided, and then click Create. This runs the stack creation job.
The Job Details page of the stack in Resource Manager is displayed. A
stack creation job name has the format ormjobyyyymmddnnnnnn
. For
example, ormjob20200922125850
. Periodically monitor the progress of the
job until it is finished. If an email address is associated with your user profile, you
will receive an email notification.
