OWLS-71579 - NPE in admin server log

[alai8]

The NPE in admin server log is caused by ServerChannel.getPublicInetAddress().getAddress() being null where the channel is the T3Channel as configured in the sample create-domain.sh scripts, which is configured using the default t3PublicAddress input parameter value of “kubernetes”. The address “kubernetes” fails to be resolved to an IP address if there is no service such as the following in the same namespace where the domain is located:

$ kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.96.0.1 443/TCP 2d

Both the domain home in image and the domain home on pv create domain samples are updated:

• remove “kubernetes” as the default value for the t3PublicAddress field in the create-domain-inputs.yaml file
• t3PublicAddress field is now optional. if customer does not provide a value, t3PublicAddress is defaulted to the IP address of the kubernetes cluster, as obtained using the existing getKubernetesClusterIP function in utility.sh
• README.md is updated to reflect the changes to t3PublicAddress
