我無法從 Intellij 連接到 Docker 上的 postgres 數據庫

Question

我正在執行與以下描述相同的步驟： https ://medium.com/better-programming/connect-from-local-machine-to-postgresql-docker-container-f785f00461a7

但是當我嘗試從 Intellij 連接到我的 postgres（使用密碼 mysecretpassword）時，出現以下錯誤：

The specified database user/password combination is rejected: [28P01] FATAL: password authentication failed for user "postgres"

當然，我可以通過 cmd 命令連接到我的數據庫：

$ psql -h localhost -p 5432 -U postgres -W                       Password for user postgres:                       
psql (9.5.5, server 10.3 (Debian 10.3-1.pgdg90+1))                       WARNING: psql major version 9.5, server major version 10.                                Some psql features might not work.                       
Type "help" for help.                                               postgres=# \l

我的容器啟動了：

到底是怎么回事？ 我不知道...我在 Intellij 中使用 postgres 驅動程序 42.2.5

來自容器的日志：

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

You can change this by editing pg_hba.conf or using the option -A, or

Success. You can now start the database server using:

    pg_ctl -D /var/lib/postgresql/data -l logfile start

Answer 1

為卷創建目錄：C:\\Users{user}\\docker\\postgres_data\\data

在 Windows 上連接到 Postgres：

docker run -p 5432:5432 --name postgres -v C:\Users\{user}\docker\postgres_data\data:/var/lib/postgresql/data -e POSTGRES_PASSWORD=root -d postgres:11.3 

從 CMD 連接到 Postgres 並創建數據庫（僅在空卷上首次創建容器后）：

docker ps
  

得到輸出：
容器 ID 圖像命令創建狀態端口名稱 e626f4c7b958 postgres:11.3 "docker-entrypoint.s..." 大約一個小時前 Up 大約一個小時 0.0.0.0:5432->5432/tcp postgres

跑：

docker exec -it {CONTAINER ID} bash
psql -h localhost -U postgres
psql -U postgres

使用 PASSWORD=root 從 Intellij 連接：

Answer 2

您似乎在 5432 端口上運行了 postgresql 實例。 檢查端口 5432 上運行的是什么：

sudo lsof -i :5432

如果有任何記錄，您可以手動殺死正在使用該端口的進程（ man kill ）並重新運行 docker 容器。 在我的例子中，這個端口上運行了另一個本地的 postgresql 實例，所以下面的內容對我有幫助：

sudo pkill -u postgres

或者（更可取）為您的 docker postgresql 指定不同的端口映射（例如 5433）：

docker run -p 5433:5432 ...other_your_flags... postgres:latest

Answer 3

嘗試刪除您在本地安裝的 PostgreSQL（如果存在）。 因為我的問題恰恰是這個想法不知道在哪里連接，到 docker survey 或我電腦上安裝的數據庫
