我是docker-ce-19.03.4-3.el7.x86_64docker的新手，我在centos7上使用。
在我的机器上：
docker run -d -p 12345:12345 oddrationale/docker-shadowsocks -s 0.0.0.0 -p 12345 -k welcome -m aes-256-cfb`
docker export -o oddss.tar ae6f 然后我使用
docker import oddss.tar oddss:v1
然后我尝试启动容器：
docker run -d -p 12345:12345 oddss:v1 -s 0.0.0.0 -p 12345 -k welcome -m aes-256-cfb。
我收到以下错误：
docker: Error response from daemon: OCI runtime create failed: container_linux.go:346: starting container process caused "exec: \"-s\": executable file not found in $PATH": unknown.
什么地方出了错？
顺便说一句：在我的机器上A i docker inspect xxxx（检查原始图像）：

因此，您遇到的问题是export无法真正捕获容器（它只是文件系统的压缩文件）-请注意，新映像没有入口点或命令。这就是该错误的含义-您的容器未entrypoint指定，因此将其解释-s 0.0.0.0 -p 12345 -k welcome -m aes-256-cfb。为入口点（并且-s不是有效命令）。
但是...不要这样做。不确定您要完成的目标，但不确定该如何运作。如果需要修改容器，请使用Dockerfile生成映像。
编辑
详细说明导出容器（您在做什么）是一个坏主意。但是，图像应以这种方式使用。docker image save而docker image import可能是你want-转一下图像成压缩包，然后回的图像，与所有成立于保留了dockerfile的图像元数据。
如果您确实需要运行一个容器然后再移动它，则可以docker commit从正在运行的容器中创建一个新映像，然后执行save/import上述操作。
