Docker无法识别Postgresql数据目录 [英] Docker not recognizing Postgresql data directory

问题描述

我拼命地尝试让我继承并运行的Docker项目开始运行，而Docker却给我带来了无尽的麻烦。尝试启动容器时，我在Postgresql容器上收到以下错误：

I am desperately trying to get a Docker project I have inherited up and running, and Docker is giving me no end of problems. When trying to start up my containers I get the following error on my Postgresql container:

FATAL:  "/var/lib/postgresql/data" is not a valid data directory
DETAIL:  File "/var/lib/postgresql/data/PG_VERSION" does not contain valid data.
HINT:  You might need to initdb.

该项目也是使用Redis，ElasticSearch和Sidekiq容器的Rails项目-所有这些都可以正常加载

The project is a Rails project using Redis, ElasticSearch, and Sidekiq containers as well - those all load fine.

docker-compose.yml：

docker-compose.yml:

postgres:
  image: postgres:9.6.2
  environment:
    POSTGRES_USER: $PG_USER
    POSTGRES_PASSWORD: $PG_PASS
  ports:
    - '5432:5432'
  volumes:
    - postgres:/var/lib/postgresql/data

/ var / lib / postgresql / data 由postgres用户拥有（应该相信），并且postgresql服务可以启动并可以正常运行。

/var/lib/postgresql/data is owned by the postgres user (as it should be I believe) and the postgresql service starts up and runs fine on its own.

我尝试从 /usr/lib/postgresql/9.6/bin initdb $ c>目录，以及来自docker的目录（从docker似乎都不会持久，甚至不会创建任何东西……如果有人知道为什么我会对知道的东西感兴趣）

I have tried running initdb from the /usr/lib/postgresql/9.6/bin directory, as well as from docker (from docker it doesn't seem to persist or even create anything... if anyone knows why I would be interested in knowing)

/ var / lib / postgresql / data 目录的内容：

PG_VERSION 包含9.6

我们非常感谢您的帮助。

Any help is much appreciated.

推荐答案

您正在更改默认的postgresql数据路径，因此需要初始化数据库。试试这个

you're changing default postgresql data path hence you need to initialize the database. try this

volumes:
    - ./init.sql:/docker-entrypoint-initdb.d/init.sql

这是init.sql文件

here is the init.sql file

CREATE USER docker;
CREATE DATABASE docker;
GRANT ALL PRIVILEGES ON DATABASE docker TO docker;
