Create a domain

Create the domain using a domain resource.

Select a user name and password for the WebLogic domain administrator credentials and use them to create a Kubernetes Secret for the domain.
```
$ kubectl create secret generic sample-domain1-weblogic-credentials \
  --from-literal=username=ADMIN_USERNAME --from-literal=password=ADMIN_PASSWORD \
  -n sample-domain1-ns
```
Replace ADMIN_USERNAME and ADMIN_PASSWORD with your choice of user name and password. Note that the password must be at least 8 characters long and must contain at least one non-alphabetical character.
Create a domain runtime encryption secret.
```
$ kubectl -n sample-domain1-ns create secret generic \
  sample-domain1-runtime-encryption-secret \
   --from-literal=password=my_runtime_password
```
These two commands create secrets named sample-domain1-weblogic-credentials and sample-domain1-runtime-encryption-secret used in the sample domain YAML file. If you want to use different secret names, then you will need to update the sample domain YAML file accordingly in the next step.
Create the sample-domain1 domain resource and an associated sample-domain1-cluster-1 cluster resource using a single YAML resource file which defines both resources. The domain resource and cluster resource do not replace the traditional WebLogic configuration files, but instead cooperates with those files to describe the Kubernetes artifacts of the corresponding domain.
- Use the following command to apply the two sample resources.
```
$ kubectl apply -f https://raw.githubusercontent.com/oracle/weblogic-kubernetes-operator/main/kubernetes/samples/quick-start/domain-resource.yaml
```
- NOTE: If you want to view or need to modify it, you can download the sample domain resource to a file called /tmp/quickstart/domain-resource.yaml or similar. Then apply the file using kubectl apply -f /tmp/quickstart/domain-resource.yaml.
The domain resource references the cluster resource, a WebLogic Server installation image, the secrets you defined, and a sample “auxiliary image”, which contains traditional WebLogic configuration and a WebLogic application.

Note

The Quick Start guide’s sample domain resource references a WebLogic Server version 14.1.2.0 General Availability (GA) image. GA images are suitable for demonstration and development purposes only where the environments are not available from the public Internet; they are not acceptable for production use. In production, you should always use CPU (patched) images from OCR or create your images using the WebLogic Image Tool (WIT) with the --recommendedPatches option.
Confirm that the operator started the servers for the domain.

a. Use kubectl to show that the Domain was created.
```
$ kubectl describe domain sample-domain1 -n sample-domain1-ns
```
b. Get the domain status using the following command. If you don’t have the jq executable installed, then run the second command to get the domain status.
```
$ kubectl get domain sample-domain1 -n sample-domain1-ns -o json | jq .status
```
OR
```
$ kubectl get domain sample-domain1 -n sample-domain1-ns -o jsonpath='{.status}'
```
c. After a short time, you will see the Administration Server and Managed Servers running.
```
$ kubectl get pods -n sample-domain1-ns
```
d. You should also see all the Kubernetes Services for the domain.
```
$ kubectl get services -n sample-domain1-ns
```
If the operator didn’t start the servers for the domain, see Domain debugging .

Create an ingress route for the domain.

Create an ingress route for the domain, in the domain namespace, by using the following YAML file.

a. Download the ingress route YAML to a file called /tmp/quickstart/ingress-route.yaml or similar.

b. Then apply the file using the following command.
```
$ kubectl apply -f /tmp/quickstart/ingress-route.yaml \
  --namespace sample-domain1-ns
```

To confirm that the ingress controller noticed the new ingress route and is successfully routing to the domain’s server pods, send a request to the URL for the “quick start app”, as shown in the following example, which will return an HTTP 200 status code.

    $ curl -i http://localhost:30305/quickstart/

Note

Depending on where your Kubernetes cluster is running, you may need to open firewall ports or update security lists to allow ingress to this port.

To access the WebLogic Server Administration Console:

  Open a browser to http://localhost:30305/console.

  a. Get the load balancer ingress IP address using the following command:
     $ LOADBALANCER_INGRESS_IP=$(kubectl get svc traefik-operator -n traefik -o jsonpath='{.status.loadBalancer.ingress[].ip}{"\n"}')

  b. Open a browser to http://${LOADBALANCER_INGRESS_IP}/console.

Note

Do not use the WebLogic Server Administration Console to start or stop servers, or for scaling clusters. See Starting and stopping servers and Scaling .
