docker swarm と docker compose は初めてです。
nginx とフラスコの docker コンテナーを使用するアプリケーションを作成しました。nginx はリバース プロキシとして機能します。
docker compose を使用してこのアプリケーション全体を構築すると、すべて正常に動作します
私の docker-compose.yml ファイル
version: '2'
services:
web:
restart: always
build: ./web
image: shivanand3939/web
expose:
- "8000"
volumes:
- ./output:/usr/src/app/static
command: /usr/local/bin/gunicorn -w 2 -b :8000 --access-logfile - classifierv2RestEndPoint_ridge_NB:create_app()
nginx:
build: ./nginx/
image: shivanand3939/nginx
ports:
- "80:80"
volumes:
- /www/static
volumes_from:
- web
links:
- web:web
viz:
image: dockersamples/visualizer
ports:
- 8080:8080/tcp
volumes:
- /var/run/docker.sock:/var/run/docker.sock
environment:
- "constraint=node.role==manager"
以下は私の出力です：
ただし、3 つの AWS インスタンスにデプロイして、次のレベルに引き上げたいと考えています。
ここに私のdocker-stack.ymlファイルがあります
version: '3'

しかし、このアプリケーションをデプロイして URL を確認すると、これが表示されます
【間違ったホームページ】
最初のケースでは Web コンテナーと nginx コンテナーの間で通信が行われたが、2 番目のケースではこの通信が停止した理由がわかりません。
誰でもこれについて私を案内してもらえますか
