推荐答案
许多容器化应用程序，尤其是有状态的应用程序，都有一种运行 init 脚本(如这里的 sql 脚本)和他们应该只运行一次.
Many containerized applications, especially stateful ones, have a way of running init scripts (like the sql scripts here) and they are supposed to run only once.
由于它们是有状态的，卷是容器在容器重启时是否运行 init 脚本的真实来源.
And since they are stateful, the volumes are a source of truth for the containers on whether to run the init scripts or not on container restart.
就像您的情况一样，删除用于绑定安装的文件夹或使用新命名的卷应该重新运行任何存在的 init 脚本.
Like in your case, deleting the folder used for bind mount or using a new named volume should re-run any init scripts present.
