You can use the WebLogic Scripting Tool (WLST) to manage a domain running in Kubernetes. If the Administration Server was configured to expose a T3 channel using the `exposeAdminT3Channel` setting when creating the domain, then the matching T3 service can be used to connect. For example, if the `domainUID` is `domain1`, and the Administration Server name is `admin-server`, then the service would be called:

```
domain1-admin-server-external

This service will be in the same namespace as the domain. The external port number can be obtained by checking this service’s `nodePort`:

```
$ kubectl get service domain1-admin-server-external -n domain1 -o jsonpath='{.spec.ports[0].nodePort}'

When introspection fails, the operator will not start any WebLogic Server instances. If this is not the initial introspection and there are already WebLogic Server instances running, then a failed introspection will leave the existing WebLogic Server instances running without making any changes to the operational state of the domain.
