postgresql - 连接到 PostgreSQL : Postico and TablePlus DB GUIs can't connect but `psql` in Docker works (FATAL: password authentication failed for user)

Question

我已经使用 Docker 在本地部署了我的 PostgreSQL 数据库。这是我的 Docker Compose 文件:

version: '3'
services:
  prisma:
    image: prismagraphql/prisma:1.30-alpha
    restart: always
    ports:
    - "4466:4466"
    environment:
      PRISMA_CONFIG: |
        port: 4466
        # uncomment the next line and provide the env var PRISMA_MANAGEMENT_API_SECRET=my-secret to activate cluster security
        # managementApiSecret: my-secret
        prototype: true
        databases:
          default:
            connector: postgres
            host: postgres
            user: prisma
            password: prisma
            port: 5432
  postgres:
    image: postgres
    restart: always
    environment:
      POSTGRES_USER: prisma
      POSTGRES_PASSWORD: prisma
    volumes:
      - postgres:/var/lib/postgresql/data
volumes:
  postgres:

我已经从 docker-compose up -d 开始了。

Docker 容器正在运行:

CONTAINER ID        IMAGE                             COMMAND                  CREATED             STATUS              PORTS                    NAMES
26b14120f89f        prismagraphql/prisma:1.30-alpha   "/bin/sh -c /app/sta…"   17 minutes ago      Up 17 minutes       0.0.0.0:4466->4466/tcp   newdm1_prisma_1
05dfdaeaf609        postgres                          "docker-entrypoint.s…"   17 minutes ago      Up 17 minutes       5432/tcp                 newdm1_postgres_1

现在，出于某种原因我无法使用数据库 GUI 进行连接(尝试过 Postico 和 TablePlus)。在两个客户端中，我都收到以下错误:

FATAL: password authentication failed for user "prisma"

我 100% 确定我提供 prisma 作为 Docker Compose 文件中指定的密码。

此外，当我从 postgres Docker 容器内部使用 psql 连接到数据库时，它确实有效:

docker exec -it 05dfdaeaf609 bash

然后在 Docker 容器中我这样做:

root@05dfdaeaf609:/# psql -U prisma -W prisma
Password: 
psql (11.1 (Debian 11.1-1.pgdg90+1))
Type "help" for help.

prisma=# \l
                              List of databases
   Name    | Owner  | Encoding |  Collate   |   Ctype    | Access privileges 
-----------+--------+----------+------------+------------+-------------------
 postgres  | prisma | UTF8     | en_US.utf8 | en_US.utf8 | 
 prisma    | prisma | UTF8     | en_US.utf8 | en_US.utf8 | 
 template0 | prisma | UTF8     | en_US.utf8 | en_US.utf8 | =c/prisma        +
           |        |          |            |            | prisma=CTc/prisma
 template1 | prisma | UTF8     | en_US.utf8 | en_US.utf8 | =c/prisma        +
           |        |          |            |            | prisma=CTc/prisma
(4 rows)

prisma=# \c prisma
Password for user prisma: 
You are now connected to database "prisma" as user "prisma".

我在 psql 中提供的密码是 prisma，类似于我在 Postico 和 TablePlus 中提供的密码。

连接到 Docker 容器中的 PostgreSQL 数据库时，我需要做什么特别的事情吗？

Answer 1

PORTS
0.0.0.0:4466->4466/tcp
5432/tcp

如果您检查 docker ps 命令的端口列，您会发现 Postgres 端口未公开供主机使用。

要解决这个问题，需要在docker-compose.yml文件中添加如下内容:

ports:
  - "5432:5432"

使完整的文件看起来像这样:

version: '3'
services:
  prisma:
    image: prismagraphql/prisma:1.30-alpha
    restart: always
    ports:
    - "4466:4466"
    environment:
      PRISMA_CONFIG: |
        port: 4466
        # uncomment the next line and provide the env var PRISMA_MANAGEMENT_API_SECRET=my-secret to activate cluster security
        # managementApiSecret: my-secret
        prototype: true
        databases:
          default:
            connector: postgres
            host: postgres
            user: prisma
            password: prisma
            port: 5432
  postgres:
    image: postgres
    restart: always
    ports:
      - "5432:5432"
    environment:
      POSTGRES_USER: prisma
      POSTGRES_PASSWORD: prisma
    volumes:
      - postgres:/var/lib/postgresql/data
volumes:
  postgres:

然后您需要运行 docker-compose up -d 来应用新的更改。正确设置后，docker ps 的 PORTS 列应该如下所示

PORTS
0.0.0.0:4466->4466/tcp
0.0.0.0:5432->5432/tcp
