typescript - 无法使用 TypeORM + pgAdmin4 连接到在 docker 上运行的本地 PostgreSQL 数据库

Question

我在本地主机上运行的 docker 中托管了一个 postgres 数据库，默认的 postgres 端口 5432 但我根本无法通过 pgAdmin4 或 TypeORM 连接到数据库。两者都抛出相同的错误，提示密码无效。

我正在使用以下 docker-compose.yml 文件来创建数据库:

version: '3.8'
services: 
    db:
        image: postgres
        volumes:
            - ./pgdata:/var/lib/postgresql/data
        ports: 
            - '5432:5432'
        environment: 
            POSTGRES_DB: maindb
            POSTGRES_USER: admin
            POSTGRES_PASSWORD: admin

因此，我希望能够通过在本地主机上输入默认端口 5432 来通过 pgAdmin4 连接到数据库(也尝试了本地主机 ip 127.0.0.1 )但是当我尝试使用以下登录时凭据(你必须相信我密码是正确输入并重新输入 10 次并复制粘贴的) 当我然后按登录时，出现以下错误:

Unable to connect to server:

FATAL: password authentication failed for user "admin"

这真的很奇怪，因为我看不出它为什么会失败。我 100% 确定环境变量已通过，因为在 docker 桌面上我可以看到它们是相同的。

我还尝试以下列方式通过 TypeORM 连接到数据库:

createConnection({
    type: 'postgres',
    host: 'localhost',
    port: 5432,
    username: 'admin',
    password: 'admin',
    database: 'maindb',
    entities: [App],
    synchronize: true,
    logging: false,
})
    .then(connection => console.log('Logged in'))
    .catch(error => console.log(error));

我收到此错误消息:

error: password authentication failed for user "admin"
REMOVED PATHS FOR CONCISENESS
 {
  length: 97,
  severity: 'FATAL',
  code: '28P01',
  detail: undefined,
  hint: undefined,
  position: undefined,
  internalPosition: undefined,
  internalQuery: undefined,
  where: undefined,
  schema: undefined,
  table: undefined,
  column: undefined,
  dataType: undefined,
  constraint: undefined,
  file: 'auth.c',
  line: '285',
  routine: 'auth_failed'
}

我也看不出这应该失败的原因。请问是PostgreSQL的问题还是docker的问题？可能我更容易切换数据库提供商？

正在初始化脚本中设置用户和密码。

如果这不是您第一次对该文件运行组合，那么您很可能已经在容器中安装的卷上拥有数据。在这种情况下，初始化脚本被跳过，您应该在 docker-compose up 输出中看到此日志:

db_1  | PostgreSQL Database directory appears to contain a database; Skipping initialization

---

这些选项中的任何一个都应该可以解决您的问题:

• 记住您第一次设置的密码，并使用该密码进行连接

或

• 清空该卷或完全删除它(@pacuna 已经在评论中解释了如何做到这一点 - 这将清除数据并从头开始重新初始化一切!)

docker-compose down -v

或

• 重置管理员密码:

// Open a console in the container
docker exec -ti <your-psql-container-id> sh

// Connect to your maindb using the admin user
psql -d maindb -U admin

// Change the admin user password
ALTER USER admin WITH ENCRYPTED PASSWORD 'admin-new-pass';

...然后使用admin-new-pass再次尝试连接

问题是由 pgAdmin4 客户端的错误配置引起的。将 pgAdmin4 客户端容器化后，在尝试重现时，问题消失了
