postgresql - 从 docker 容器访问主机 postgres

Question

我有一个 CentOS 7 服务器，在其上分别运行 postgres(端口 5432)和 docker。

目前我正在尝试从我的 docker 容器访问 postgres 数据库。但我收到以下错误:

    at Connection.parseE (/usr/app/node_modules/pg/lib/connection.js:604:11)
    at Connection.parseMessage (/usr/app/node_modules/pg/lib/connection.js:401:19)
    at Socket.<anonymous> (/usr/app/node_modules/pg/lib/connection.js:121:22)
    at Socket.emit (events.js:198:13)

    at TCP.onStreamRead [as onread] (internal/stream_base_commons.js:94:17)
  name: 'error',
  length: 161,
  severity: 'FATAL',
  code: '28000',
  detail: undefined,
  hint: undefined,
  position: undefined,
  internalPosition: undefined,
  internalQuery: undefined,

  table: undefined,
  column: undefined,
  dataType: undefined,
  constraint: undefined,
  file: 'auth.c',
  line: '489',
  routine: 'ClientAuthentication' }```

I have change pg_hba.conf of my host postgres application that too didn't solve the issue.
Any help will be appreciated.

感谢克莱曼斯的帮助，我得到了解决方案。问题是由于 docker 网络，因为它无法连接到主机。因为默认情况下我的容器在 docker 网桥中运行。我将其更改为遇到解决我的问题的主机。下面是我用来运行我的容器的命令docker run --network=host -d <image name>
