Olá Jose Carlos, tudo bem? É estranho esse erro, fiz o mesmo procedimento aqui e deu tudo certo, você poderia disponibilizar o conteúdo do arquivo docker-compose.yml pra gente pode analisar e verificar qual o possível erro!

Deletei as vm duas vezes e refiz o processo e realmente com este arquivo abaixo não funciono. Porém outro que fiz esta funcionando o Banco Cassandra e o portainer

version: "3"
services:

  redis:
    image: redis:alpine
    networks:
      - frontend

  db:
    image: postgres:9.4
    volumes:
      - db-data:/var/lib/postgresql/data
    networks:
      - backend

  vote:

    ports:
      - 5000:80
    networks:

    depends_on:
      - redis

  result:

      - backend
    depends_on:

  worker:

    volumes:

José Carlos, você poderia executar usando o seguinte conteúdo no arquivo:

version: "3"
services:

  redis:
    image: redis:alpine
    networks:
      - frontend
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure

  db:
    image: postgres:9.4
    volumes:
      - db-data:/var/lib/postgresql/data
    networks:
      - backend
    deploy:
      placement:
        constraints: [node.role == manager]

  vote:
    image: dockersamples/examplevotingapp_vote:before
    ports:
      - 5000:80
    networks:
      - frontend
    depends_on:
      - redis
    deploy:
      replicas: 2
      restart_policy:
        condition: on-failure

  result:
    image: dockersamples/examplevotingapp_result:before
    ports:
      - 5001:80
    networks:
      - backend
    depends_on:
      - db
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure

  worker:
    image: dockersamples/examplevotingapp_worker
    networks:
      - frontend
      - backend
    depends_on:
      - db
      - redis
    deploy:
      mode: replicated
      replicas: 1
      labels: [APP=VOTING]
      restart_policy:
        condition: on-failure
      placement:
        constraints: [node.role == worker]

  visualizer:
    image: dockersamples/visualizer:stable
    ports:
      - 8080:8080
    stop_grace_period: 1m30s
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
    deploy:
      placement:
        constraints: [node.role == manager]

networks:
  frontend:
  backend:
