Docker containers requests return Error: read ECONNRESET

Question

我正在使用 docker-compose 来启动两个容器：一个带有 micronaut 服务，一个带有 postgres。

这是我的docker-compose.yml

version: "3.8"

services:
  web:
    image: "time"
    container_name: "time"
    build:
      context: .
      network: bridge
    ports:
      - "8081:8080"
    depends_on:
      - db
    links:
      - "db"
    environment:
      - PGHOST=db
      - PGDATABASE=postgres
      - PGUSER=postgres

  db:
    image: "postgres"
    ports:
      - "5432:5432"
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: time

但是当我尝试向我的端点之一发送请求时，什么也没有发生，直到最终我收到错误：读取 ECONNRESET

当然，当我 运行 我的应用程序在 docker 之外的电脑上时，我可以正常发送请求。我的设置有问题吗？

其他设置工作正常，但我想知道如何让两个容器像我的第一个 docker-compose 一样连接并能够从我的主机访问它们。

version: "3.8"

services:
  web:
    image: "time"
    container_name: "time"
    build: .
    depends_on:
      - db
    environment:
      - PGHOST=db
      - PGDATABASE=postgres
      - PGUSER=postgres
    network_mode: host

  db:
    image: "postgres"
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: time
    network_mode: host
