Renaming a service doesn't rename/update the services's containers/tasks:
$ docker service create --name web nginx:alpine

$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e4e8461a30d2 nginx:alpine "nginx -g 'daemon off" 1 seconds ago Up Less than a second 80/tcp, 443/tcp web.1.2onlllux6w6haprqyjpzyx2fz
$ docker service update --name frontend web

$ docker ps

New containers/tasks are named after the new service name:
$ docker service update --replicas=2 frontend

$ docker ps

It becomes more confusing if you inspect the containers;
$ docker inspect frontend.2.38oyjutl1ljis0a3n2psimmfd
