在 docker 上运行时 PostgreSQL 不创建表

Question

我正在尝试运行我的 Windows 服务器中的 linux 容器 docker 上的 PostgreSQL，但是当我运行它时，它会创建数据库，但没有 table 并且其中没有数据，而它应该创建所有 table 并使用 Actibook_latest.sql

向其中添加数据

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! ***"

这里是 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。 Actibook_latest.sql 还包含 sql 以创建 table、数据等

当我运行 docker-compose up 而其他服务上升并运行ning 时，这是它向日志显示的内容：

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

我认为可能存在防火墙问题，因为它运行在我拥有的其他服务器上完美运行，问题只出现在这台服务器上。那么这台机器中的 postgresql 是否有可能阻止它？

更新

我尝试重新启动 docker 然后使用了这些命令：

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

表示存在Actibook_latest.sql

Answer 1

您的入口点初始化脚本似乎无法正常工作，请确保 data_volume 在您的容器运行之前为空。

这是因为在docker-entrypoint.sh的第57行，它会检查你的数据量，如果存在，它不会执行你的init scrip。
