Docker撰写mysql import .sql


Docker Compose mysql import .sql

我在用Docker Compose导入.sql转储文件时遇到问题。我已经跟踪了这些文档，它们显然会从docker entrypoint initdb.d加载.sql文件。但是，当我运行docker-compose up时，SQL文件不会复制到容器中。

我试过用-vf旗阻止集装箱，但也没用。我的.yml脚本有问题吗？

我的compose文件所在的根目录database/db dump/中有dump.sql。

在多次尝试卷设置后，我发现了一个解决方法

我创建了另一个基于mysql的图片，在dockerfile中包含以下内容

1

3
FROM mysql:5.6

ADD dump.sql /docker-entrypoint-initdb.d

然后从撰写中删除卷并运行新映像

    MYSQL_PASSWORD: userpass
    MYSQL_DATABASE: myimage_db

这样，转储总是被复制并在启动时运行。

这出现在docker mysql图片的文档页面：https://hub.docker.com//mysql/

Initializing a fresh instance

When a container is started for the first time, a new database with
the specified name will be created and initialized with the provided
configuration variables. Furthermore, it will execute files with
extensions .sh, .sql and .sql.gz that are found in
/docker-entrypoint-initdb.d. Files will be executed in alphabetical
order. You can easily populate your mysql services by mounting a SQL
dump into that
directory
and provide custom
images with contributed
data. SQL files will be imported by default to the database specified
by the MYSQL_DATABASE variable.

这对我很有用，

mysql dump必须是目录。将导入目录中的所有.sql。

mysql database dump schema.sql驻留在/mysql dump/schema.sql目录中，它在初始化过程中创建表。
