docker stack deploy --compose-file=docker-compose.yml selenium の使い方について

compose.yml で　docker swarm に使う selenium hub と chrome , react app , django app, nginx を定義しています。
docker stack deploy --compose-file=docker-compose.yml selenium というコードによりデプロイをしているのですが、 下記のようなエラーが出ます。どのようにすればいいのかアドバイスをいただきたいです。

error
