docker撰写将保持传统卷，现在不能清除它们

docker撰写将保持传统卷，现在不能清除它们

我试图将当前目录安装到容器中，

并多次更改挂载名称，

比如crawler – > data-crowler – > … root

但是，一旦我安装它，即使我更改了mount volume name ，它仍将保留在容器中

我从来没有使用USER seluser做任何事情，

但是你可以看到文件夹的所有者是seluser

这怎么可能发生？

Dockerfile结束

 EXPOSE 4444 WORKDIR /lazy-bird CMD ["/usr/bin/supervisord"] 

泊坞窗，compose.yml

 web: build: . volumes: - .:/lazy-bird 

根目录

回答你的一个问题：

我从来没有使用USER seluser做任何事情，

但是你可以看到文件夹的所有者是seluser

这怎么可能发生？

你需要用下面的方法跟踪Dockerfiles中的所有步骤，然后你应该知道什么时候该图像与USER seluser
