無法從ubuntu上的docker-compose連接到postgres

Question

我正在嘗試從docker-compose.yml文件連接到在數字海洋上托管的Ubuntu 18.04上運行的postgres數據庫。 .yml文件包含以下內容：

version: '3'
services:
  prisma:
    image: prismagraphql/prisma:1.32
    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
        databases:
          default:
            connector: postgres
            host: droplet-ip
            database: my-database
            user: my-user
            password: my-password
            rawAccess: false
            port: 5432
            migrations: true

我嘗試使用'localhost'，'127.0.0.1'和'host.docker.internal'作為主機，但它都沒有用。 我已經將pg_hba.conf配置為偵聽范圍127.0.0.1/16和postgresql.conf的listen_address ='*'。 我嘗試連接時從postgres獲取以下日志：

No log level set, defaulting to INFO.
[INFO] {} - Started.

我正在使用docker-compose，ubuntu 18.04和postgreSQL 10。

知道我在哪里可能會出錯嗎？

Answer 1

嘗試在你docker-compose.yml使用它：

network: host

並更改docker-compose.yml的IPs以使用您在UBUNTU上使用的內容，或者現在只需使用localhost
