Question

我正在尝试启动一个postgres数据库容器。启动容器后，我还希望在其中创建模式和表。

我正在尝试将.sql文件复制到docker入口点中。

我的Dockerfile：

FROM postgres 
ENV POSTGRES_PASSWORD postgres 
ENV POSTGRES_DB MY_APP_DB
COPY my-app-db-ddl.sql /docker-entrypoint-initdb.d/

DDL文件内容：

CREATE SCHEMA MY_APP_DB;

CREATE TABLE MY_APP_DB.ACCESS_MASTER
(
    "ACCESS_ID" character varying COLLATE pg_catalog."default" NOT NULL,
    "ROLE_ID" character varying COLLATE pg_catalog."default",
);

上面的脚本有助于创建数据库，但不能创建架构/表。我该如何实现？

请帮助。

0.Dockerfile

from postgres

更正sql中的错误：

CREATE SCHEMA MY_APP_DB;

CREATE TABLE MY_APP_DB.ACCESS_MASTER
(
    "ACCESS_ID" character varying COLLATE pg_catalog."default" NOT NULL,
    "ROLE_ID" character varying COLLATE pg_catalog."default"
);

在您本地的目录中创建一个目录，并以docker -v /opt/import1:/docker-entrypoint-initdb.d/的身份挂载

cat /opt/import/setup.sql

root@ubuntu:/home/sathya/Desktop/stackoverflo/docker/postgres# cat /opt/import1/setup.sql 
create schema my_app_db;
CREATE TABLE my_app_db.access_master ("ACCESS_ID" character varying COLLATE pg_catalog."default" NOT NULL,"ROLE_ID" character varying COLLATE pg_catalog."default");

root@ubuntu:/home/sathya/Desktop/stackoverflo/docker/postgres# cat Dockerfile 
from postgres

docker run --name 683dd2ba4015 -p 5432:5432 -v /opt/import1:/docker-entrypoint-initdb.d/ -e POSTGRES_HOST_AUTH_METHOD=trust -d postgres

root@ubuntu:/home/sathya/Desktop/stackoverflo/docker/postgres# docker ps
