已经全部删除了 ，为何查看镜像还有呢 ？

Answer 1

What you delete is the instance running the image. To delete the image, use docker rmi + image name or the string of characters

Answer 2

Image and container are two concepts. An image can be understood as a class object, and a container can be understood as an instance of a class.

Answer 3

docker rm is to delete the container, and your docker images is to list the images. Images and containers are different concepts.
