Question

我正尝试从docker-compose.yml文件连接到在数字海洋上托管的Ubuntu 18.04上运行的postgres数据库。 .yml文件包含以下内容：

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

我尝试使用“ localhost”，“ 127.0.0.1”和“ host.docker.internal”作为主机，但没有一个起作用。我已经将pg_hba.conf配置为侦听范围127.0.0.1/16和postgresql.conf的listen_address ='*'。尝试连接时，我从postgres获取以下日志：

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

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

你知道我可能在哪里出错吗？

Answer 1

尝试在您的docker-compose.yml中使用它：

network: host

并更改IPs中的docker-compose.yml以使用您在UBUNTU上使用的内容，或者现在只需使用localhost

无法从ubuntu上的docker-compose连接到Postgres
