Init种子DB以及postgre docker容器

Question

我正在尝试创建一个新的postgres数据库。

仅限初学者 - 创建新卷：

docker volume create test

然后启动图像。

docker run  -v test:/var/lib/postgresql/data -p 5432:5432 nec-postgres

现在这是我的Dockerfile：

FROM postgres:10.4

ENV POSTGRES_USER=user
ENV POSTGRES_PASSWORD=pass
ENV POSTGRES_DB=smdr

COPY *.sql /docker-entrypoint-initdb.d/

看起来很简单，并且根据https://hub.docker.com/_/postgres/假设要创建一个数据库，并在卷为空时在该数据库上运行init脚本。

当我第一次开始拍摄我的照片时，我得到了预期的效果：

/usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/1_database.sql
CREATE TABLE
CREATE TABLE
CREATE TABLE
CREATE TABLE
ALTER TABLE
ALTER TABLE
ALTER TABLE
ALTER TABLE

在我看到初始化之后（再次，如预期的那样）

现在，无论我做什么，我的数据库都是空的。连接到数据库后，我没有在数据库中看到任何表格或任何数据。

我尝试了10.4和10.4-阿尔卑斯山，我尝试了9.6-阿尔卑斯山，但似乎无法让那件事起作用。

我很感激任何建议。

<小时/> 更新＃1：

这是postgres的完整启动日志：

root@smdr:/home/smdr/nec# docker logs smdr_nec-postgres.ytyrdw0r2j76aytclj3d9tusj.0vd91n153gxeydsbjp730tlvj
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

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:

    pg_ctl -D /var/lib/postgresql/data -l logfile start

Answer 1

Init种子DB以及postgre docker容器

version: '2'
services:
    postgresql:
        image: postgres:9.6.5
        # uncomment to maintan persistance
        # volumes:
        # uncomment to maintan persistance
        #    - ~/volumes/jhipster/postgree/postgresql/:/var/lib/postgresql/data/
        # init with the initial sql file
        #    - ./init.sql:/docker-entrypoint-initdb.d/init.sql
        environment:
            - POSTGRES_USER=postgree
            - POSTGRES_PASSWORD=
        ports:
            - 5432:5432

注意＃1

请注意，您可以将多个脚本链接到该文件夹，它们将全部运行（按字母顺序排列）

volumes:
  - ./init1.sql:/docker-entrypoint-initdb.d/1-schema.sql
  - ./init2.sql:/docker-entrypoint-initdb.d/2-data.sql

注意＃2

确保指向目录而不是文件。因此，不是直接引用文件，而是在拥有大量文件时可以挂载目录

volumes:
  - ./path/to/my/host/folder:/docker-entrypoint-initdb.d/
  - ./path/to/my/host/folder:/docker-entrypoint-initdb.d/

Answer 2

我认为实际上postgres可以正常工作。问题出在我要连接的数据库的名字上。我正在连接到名为smdr的数据库，但是脚本在postgres数据库中运行。我不确定这是否是错误，我只是将我的东西移到了postgres数据库中。

Postgres不会在docker中初始化数据库
