無法使用 TypeORM + pgAdmin4 連接到在 docker 上運行的本地 PostgreSQL 數據庫

Question

我有一個托管在 docker 中的 postgres 數據庫，該數據庫在 localhost 上運行，默認 postgres 端口為5432 ，但我根本無法通過 pgAdmin4 或 TypeORM 連接到數據庫。 兩者都拋出相同的錯誤，說密碼無效。

我正在使用以下docker-compose.yml文件來創建數據庫：

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，我希望能夠通過 pgAdmin4 通過在 localhost 上輸入默認端口 5432 連接到數據庫（也嘗試過 localhost ip 127.0.0.1 ）但是當我嘗試使用以下憑據登錄時（您必須相信我的密碼輸入正確並重新輸入 10 次並復制粘貼） 當我然后按登錄時，我收到以下錯誤：

Unable to connect to server:

FATAL: password authentication failed for user "admin"

這真的很奇怪，因為我看不出它為什么會失敗。 我 100% 確定在 docker 桌面上傳遞了環境變量，我可以看到它們是相同的。

我還嘗試通過以下方式通過 TypeORM 連接到數據庫：

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));

我收到此錯誤消息：

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'
}

我也看不出這應該失敗的原因。 請問是PostgreSQL問題還是docker問題？ 我可能更容易切換數據庫提供商？

正在初始化腳本中設置用戶和密碼。

如果這不是您第一次在該文件上運行組合，則很可能您已經在容器中安裝的卷上有數據。 在這種情況下，初始化腳本被跳過，您應該在 output 上的 docker-compose 上看到此日志：

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

---

這些選項中的任何一個都可以解決您的問題：

• 記住您第一次設置的密碼並使用該密碼進行連接

或者

• 清空該卷或完全刪除它（@pacuna 已經在評論中解釋了如何做到這一點 - 這將清除數據並從頭開始重新初始化所有內容！）

docker-compose down -v

或者

• 重置管理員密碼：

// 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';

...然后再次嘗試使用admin-new-pass進行連接

故障排除后編輯：
該問題是由 pgAdmin4 客戶端的錯誤配置引起的。 在容器化 pgAdmin4 客戶端后，在嘗試重現時，問題消失了
