Question

我正在尝试从Redash连接到本地Postgres。（均来自redash.io和http://0.0.0.0:5000/），但无法与其连接。我可以连接localhost的其他工具，但是从Redash收到错误消息：

 Connection Test Failed:
 could not connect to server: Connection refused Is the server running 
 on host "localhost" (::1) and accepting TCP/IP connections on port 
 5432? could not connect to server: Connection refused Is the server 
 running on host "localhost" (127.0.0.1) and accepting TCP/IP 
 connections on port 5432?

任何想法可能是什么问题？我在本地Redash中使用了docker，这可能会导致问题，但是从redash.io中也得到了相同的错误。

这是我的docker-compose文件：

# This configuration file is for **development** setup. For production, refer to
# docker-compose.production.yml.
version: '2'
services:

    build: .
    command: dev_server

    restart: unless-stopped
  postgres:
    image: postgres:9.5.6-alpine
    # The following turns the DB into less durable, but gains significant performance improvements for the tests run (x3
    # improvement on my personal machine). We should consider moving this into a dedicated Docker Compose configuration for
    # tests.
    command: "postgres -c fsync=off -c full_page_writes=off -c synchronous_commit=OFF"
    restart: unless-stopped

您可以在this repo中看到整个项目。谢谢。

将localhost更改为host.docker.internal 使它起作用。
