尝试在mysql测试容器示例中创建架构时遇到以下问题。测试用户似乎没有相应的权限？
配置：

spring.datasource.driver-class-name=org.testcontainers.jdbc.ContainerDatabaseDriver
spring.datasource.url=jdbc:tc:mysql:5.7.22:///test?TC_INITSCRIPT=component/db/init_mysql.sql

Caused by: org.testcontainers.ext.ScriptUtils$UncategorizedScriptException: Failed to execute database script from resource [create schema new_schema CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;]

组件/db/init\ u mysql.sql

create schema new_schema CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

在jdbc集成之外创建mysql映像时也会遇到类似问题：

private static final MySQLContainer mysqlContainer = new MySQLContainer<>(DockerImageName.parse("mysql:5.7"))
            .withInitScript("component/db/init_mysql.sql")
            .withUsername("user")
            .withPassword("password")
            .withExposedPorts(3306)
            .withReuse(true);

关于如何在不使用预先创建的模式创建自定义docker映像的情况下实现这一点，有什么想法吗？
任何帮助都将不胜感激，我觉得我一定是错过了什么。
