mysql - 如何使MYSQL在Docker运行时启动并在Dockerfile中创建mysql用户

Question

我有一个Dockerfile(如下所示)。图像生成没有问题。安装了所有我期望的项目。但是，我正在“还原”的MYSQL用户和数据库似乎不存在。我必须执行到实例并再次手动启动mysql服务，添加用户，创建数据库，然后再次运行gunzip行。我希望在图像生成时发生这种情况，然后希望mysql在run命令上启动。任何帮助表示赞赏。

更新了

因此，我了解到我试图创建mysql用户，数据库和还原数据库的原始版本不起作用。因此，在研究中，似乎应该将.sh或.sql文件等放入/docker-entrypoint-initdb.d/中，并且它们应该在我第一次运行容器时运行。但是，这似乎对我不起作用，因此很明显我缺少了一些东西。我也将下面的.sh文件也包括在内。

我用来运行容器的命令是:

docker run -detach -v ~/hosts/web-application:/var/www/html -p 80:80 -p 443:443 -p 3306:3306 -p 22:22 --name container_1 container_image

我用来生成图像的命令是:

docker build -t container_image .

初始化文件

#!/bin/bash

/etc/init.d/mysql start

mysql -u root -e "CREATE USER 'tsc_user'@'%' IDENTIFIED BY 'tsc_user';"
mysql -u root -e "CREATE USER 'the_master'@'%' IDENTIFIED BY 'the_master';"
mysql -u root -e "GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, SHOW VIEW ON *.* TO 'tsc_user'@'%';"
mysql -u root -e "GRANT SELECT ON *.* TO the_master'@'%';"
mysql -u root -e "CREATE DATABASE tsc_sandbox;"

gunzip < /tsc-20200310.sql.gz | mysql -u root tsc_sandbox;

值得注意的是，我显然可以在之后执行到容器中并运行该Shell文件，一切都会按预期进行。只是希望当我使用docker run命令时发生这种情况。

我想至少用部分答案进行更新。我还没有弄清楚如何做我想做的所有事情，但至少我已经走得更远了。由于我已经在使用 super 用户，因此我在其中添加了mysql的启动。在下面，您可以看到我的Dockerfile，.sh文件，default和supervisord.conf文件。

[program:php-fpm7.4]

理想情况下，我将能够在第一次运行docker时运行db-init.sh脚本，而无需执行并运行它。除此之外，到目前为止，这还算不错。
