docker-can'；t更改文件（wso2）

我正在使用docker 18.04并运行wso2物联网服务器。我想使用本教程更改ip地址。我正在使用附加的docker compose文件。我正在使用创建一个容器

sudo docker-compose up

然后我就跑

sudo -it -u 0 <container-id> bash

所有已丢弃的更改。但奇怪的是，如果我创建一个新的文件e。G在conf目录中，即使重新启动，该文件仍保留。 有人能给我解释一下吗

据我所知，在容器被删除之前，可写层应该是可用的。但这不是使用Docker的预期方式。在这种情况下，如果需要运行change ip脚本，我认为最好创建一个新的Docker映像，在Docker映像创建过程中执行change ip脚本
