我查看了瓶装水的github MD文件以使用docker来使用它，而我遇到了有关postgresql的问题
如果我运行docker-compose run --rm postgres psql我得到错误

psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
这是我的docker-compose.yml文件中的postgres和psql的配置
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
我已经在这里待了几天了，任何帮助都将不胜感激！谢谢
这是docker compose的文献记载很少的功能，因为它也使我措手不及。它在文档中。看看是否可以找到它。
链接两个容器时，将使用虚拟主机名链接它们。如果检查/etc/hosts您的psql联系人，则会发现别名行，postgres {foldername}_postgres_1其中docker {foldername}-compose项目的父文件夹名称是。
要使用链接的容器，请使用主机名postgres。
例如：
psql:
image: postgres:9.4
links:
- postgres
command: 'sh -c ''exec psql -h "postgres" -p "5432" -U postgres'''
您可以配置您的代码库以使用它。如果要在链接容器之外运行代码，只需修改主机/etc/hosts文件以指向所需的服务即可。
