This error message indicates that Kubernetes was unable to find the ConfigMap named “tomcat-config” that is needed to set up a volume called “tomcat-config”.
To resolve this issue, you should check whether the ConfigMap exists in the same namespace as your application. If it does not exist, you can create it using the kubectl command line tool or by defining it in a YAML file and applying it using kubectl apply.
If the ConfigMap does exist, make sure that the name is spelled correctly in both your Pod specification and in the actual ConfigMap definition. You may also want to check if there are any permission issues preventing your Pod from accessing the ConfigMap.
