It means you have to sort it by deployment name

Your command looks good, just update the custom-column from NAME to DEPLOYMENT

kubectl get deployments -n admin2406 --sort-by=.metadata.name -o custom-columns=DEPLOYMENT:.metadata.name,CONTAINER_IMAGE:.spec.template.spec.containers[*].image,READY_REPLICAS:.status.readyReplicas,NAMESPACE:.metadata.namespace
