docker stop $(docker ps -a -q)

docker system prune

Remove all unused containers, networks, images (both dangling and unreferenced), and optionally, volumes.

For example uses of this command, refer to the examples section below.

docker rmi removes images by their ID.

To remove the image, you first need to list all the images to get the Image IDs, Image name and other details. By running simple command

docker images -a

or

docker images

After that you make sure which image want to remove, to do that executing this simple command docker rmi <your-image-id>. Then you can confirm that image has been removed or not by list all the images and check.

There is a way to remove more than one images at a time, when you want to remove multiple specific images. So to do that first get Image IDs simply by listing the images then execute simple followed command.

docker rmi <your-image-id> <your-image-id> ...

Write Images IDs in the command followed by the spaces between them.

To remove all images there is a simple command to do that.

docker rmi $(docker images -q)

Here in the above command, there are two command the first which execute in the

$()

is shell syntax and returns the results whatever executed in that syntax. So in this

-q- is a option is used to provide to return the unique IDs

$() returns the results of image IDs and then docker rmi removes all those images.
