Docker 与 NestJS PostgreSQL 组合未连接

Question

我曾尝试使用 PostgreSQL 对 NestJS 应用进行 dockerize。 Postgres 拒绝连接并且还显示了一个日志 database system was shut down at <<some timestamp>>。这是 docker-compose.yml 和日志。

version: '3'
services:
  postgres:
    image: postgres
    restart: always
    volumes:
      - ./pgdata:/var/lib/postgresql/data
    ports:
      - '5432:5432'
    environment:
      - POSTGRES_DB=gm
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
  pgadmin:
    image: dpage/pgadmin4
    environment:
      - PGADMIN_DEFAULT_EMAIL=admin@gmail.com
      - PGADMIN_DEFAULT_PASSWORD=admin
      - PGADMIN_LISTEN_PORT=5050
    ports:
      - "5050:5050"
  api:
    image: gm-server
    build:
      dockerfile: Dockerfile
      context: .
    volumes:
      - .:/home/node
    ports:
      - '8081:4001'
    depends_on:
      - postgres
    env_file: .env
    command: npm run start:prod
volumes:
  pgdata:

而且我还尝试了大部分相关答案（在 Stackoverlow 将我标记为重复之前），但它们没有用。是的，我已经尝试按照之前的建议将主机更改为host.docker.internal

为了更清楚，这是我在 NestJS 中的 typeorm-datasource 配置

import { DataSource } from 'typeorm';

export const typeOrmConnectionDataSource = new DataSource({
  type: 'postgres',
  host: 'host.docker.internal',
  port: 5432,
  username: 'postgres',
  password: 'postgres',
  database: 'gm',
  entities: [__dirname + '/**/*.entity{.ts,.js}'],
  migrations: [__dirname + '/migrations/**/*{.ts,.js}'],
  logging: true,
  synchronize: false,
  migrationsRun: false,
});

为什么这个问题与其他“重复”问题不同？

这个问题不同的原因是因为

1. 其他线程也没有解决问题。
2. 即使我们认为他们这样做，解决方案对我也不起作用。

   更多证据？

   • I have tried all solutions for this one
   • Another solution with didn't work.
   • Another one, even followed the chat

Answer 1

显然问题在于 NestJS 由于我对其脚本的自定义而无法正确编译。检查这是否是一个问题。

解决此问题后，只需按照说明使用“postgres”作为主机，它就会起作用（如果您遇到同样的问题）。
