Docker 没有创建数据库

Question

我有 Dockerfile:

FROM postgres
ENV POSTGRES_USER root
ENV POSTGRES_PASSWORD root
ENV POSTGRES_DB world
COPY world.sql /docker-entrypoint-initdb.d/

我运行 docker build -t postgres，然后我创建了容器，但它没有在PG中创建数据库。有人知道吗？

world.sql :

CREATE TABLE city (
                      id integer NOT NULL,
                      name text NOT NULL,
                      countrycode character(3) NOT NULL,
                      district text NOT NULL,
                      population integer NOT NULL
);

CREATE TABLE country (
                         code character(3) NOT NULL,
                         name text NOT NULL,
                         continent text NOT NULL,
                         region text NOT NULL,
                         surfacearea real NOT NULL,
                         indepyear smallint,
                         population integer NOT NULL,
                         lifeexpectancy real,
                         gnp numeric(10,2),
                         gnpold numeric(10,2),
                         localname text NOT NULL,
                         governmentform text NOT NULL,
                         headofstate text,
                         capital integer,
                         code2 character(2) NOT NULL,
                         CONSTRAINT country_continent_check CHECK ((((((((continent = 'Asia'::text) OR (continent = 'Europe'::text)) OR (continent = 'North America'::text)) OR (continent = 'Africa'::text)) OR (continent = 'Oceania'::text)) OR (continent = 'Antarctica'::text)) OR (continent = 'South America'::text)))
);

CREATE TABLE countrylanguage (
                                 countrycode character(3) NOT NULL,
                                 "language" text NOT NULL,
                                 isofficial boolean NOT NULL,
                                 percentage real NOT NULL
);

Answer 1

语法问题

ENV POSTGRES_USER=root
ENV POSTGRES_PASSWORD=root
ENV POSTGRES_DB=world

Answer 2

能否提供容器日志？

我运行你的解决方案，但它适用于我的情况

数据库创建成功

docker run -d --name my-postgresdb-container -p 5432:5432 postgres
docker logs <CONTAINER ID>

Docker 没有创建数据库

Docker doesn't create database

java

postgresql

spring

docker

dockerfile
