modifies the content of the parent container, other sub-container of the parent container will be affected. Therefore, the parent container is made into a read-only image, so that its sub-container cannot be modified. On the other hand, the container is dynamic. similar to a set of code managed in git, the image is equivalent to a commit (the command for generating an image from the container in docker is exactly a commit ). The container can only be
