docker-compose psql无法连接到服务器
我看了瓶装水的github MD文件使用docker，我遇到了关于postgresql的一个问题
如果我运行docker-compose run --rm postgres psql我得到的错误

这是我的docker-compose.yml文件中的postgres和psql的configuration
postgres: build: ./tmp dockerfile: Dockerfile.postgres hostname: postgres ports: - '45432:5432' psql: image: postgres:9.4 links: - postgres command: 'sh -c ''exec psql -h "localhost" -p "5432" -U postgres'''
这是我的pg_hba.conf文件
local all postgres peer # TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust # IPv4 local connections: host all all 127.0.0.1/32 md5 # IPv6 local connections: host all all ::1/128 md5 # Allow replication connections from localhost, by a user with the # replication privilege. #local replication postgres peer #host replication postgres 127.0.0.1/32 md5 #host replication postgres ::1/128 md5
我已经在这几天了，任何forms的帮助，将不胜感激！谢谢
这是一个docker写作function不佳的文档，因为它也让我不敢恭维。 它在文档中 。 看看你能不能find它。
当两个容器链接时，它们使用虚拟主机名进行链接。 如果你检查你的psql conainer的/etc/hosts ，你会发现一行别名postgres {foldername}_postgres_1其中{foldername}是你的docker-compose项目的父文件夹的名字。
要使用链接的容器，请使用主机名postgres 。
举个例子：
psql: image: postgres:9.4 links: - postgres command: 'sh -c ''exec psql -h "postgres" -p "5432" -U postgres'''
你也可以configuration你的代码库来使用它。 如果要在链接容器外部运行代码，只需修改主机/etc/hosts文件以指向所需的服务。
