This warning message is informing the user that the resource helmcharts/traefik is missing a required annotation, which should have been created when the resource was initially deployed using kubectl create –save-config or kubectl apply. The missing annotation will be automatically patched by Kubernetes.
It is important to note that kubectl apply should only be used on resources created declaratively, as opposed to those created imperatively with commands like kubectl run or kubectl create deployment. This helps ensure consistency and accuracy in the deployment process.
