Question

我试图在Windows服务器中的linux容器docker上运行PostgreSQL，但是当我运行PostgreSQL时，它创建数据库，但是其中没有表且没有数据，而它应该创建所有表并向其中添加数据使用Actibook_latest.sql

这是Dockerfile

的代码

# Dockerfile
FROM postgres:9.4

RUN mkdir -p /tmp/psql_data/

COPY Actibook_latest.sql /tmp/psql_data/
COPY init_docker_postgres.sh /docker-entrypoint-initdb.d/

EXPOSE 5432

这是init_docker_postgres.sh

的代码

#!/bin/bash
# this script is run when the docker container is built
# it imports the base database structure and create the database for the tests
DATABASE_NAME="postgres"
DB_DUMP_LOCATION="/tmp/psql_data/Actibook_latest.sql"

echo "*** CREATING DATABASE ***"

psql "$DATABASE_NAME" < "$DB_DUMP_LOCATION";

echo "*** DATABASE CREATED! ***"

这是docker-compose

的代码

version: '2'

services:
 db:
    build: '.\Main Database Backup'
    environment:
      POSTGRES_DB: ${DB_POSTGRES_APP_DATABASE}
      POSTGRES_USER: ${DB_POSTGRES_APP_USER}
      POSTGRES_PASSWORD: ${DB_POSTGRES_APP_PASSW}
      PGDATA: /var/lib/postgresql/data/pgdata
    ports:
      - "5432:5432"
    restart: unless-stopped

Main Database Backup是包含该Dockerfile和init_docker_postgres.sh的文件夹。此外，Actibook_latest.sql包含用于创建表，数据等的sql。

当我运行docker-compose up而其他服务启动并运行时，日志显示如下：

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

    postgres -D /var/lib/postgresql/data/pgdata
or
    pg_ctl -D /var/lib/postgresql/data/pgdata -l logfile start

我认为防火墙可能存在问题，因为它可以在我拥有的其他服务器中完美运行，该问题仅在此服务器中出现。那么，这台机器中的postgresql是否有阻止它的机会？

更新

我尝试重新启动docker，然后使用以下命令：

docker rm $(docker ps -a -q)
docker rmi $(docker images -a -q)
docker volume rm $(docker volume ls -q)

现在显示此错误：

/usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/init_docker_postgres.sh
*** CREATING DATABASE ***
: No such file or directory/init_docker_postgres.sh: line 4: /tmp/psql_data/Actibook_latest.sql
/docker-entrypoint-initdb.d/init_docker_postgres.sh: line 4: $'\r': command not found
*** DATABASE CREATED! ***

当我去docker检查文件时：

docker exec -it db bin
cd /tmp/psql_data 
ls

它表明存在Actibook_latest.sql

您的入口点初始化脚本似乎不起作用，请在运行容器之前确保data_volume为空。

这是因为在docker-entrypoint.sh的第57行，它检查您的数据量（如果存在），它将不会执行您的初始化脚本。

PostgreSQL在Docker上运行时未创建表
