从 docker 容器访问主机 postgres

Question

我有一台 CentOS 7 服务器，其上的 postgres（端口 5432）和 docker 是运行。

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)

  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 Clemans 的帮助，我得到了解决方案。问题是由于 docker 网络无法连接到主机。因为默认情况下我的容器是运行ning 在 docker 网桥中。我将其更改为运行 into host 解决了我的问题。下面是我用来运行我的容器的命令 docker run --network=host -d <image name>
