The “docker images” command with no arguments is the simplest way to list Docker images. When you run this command, you will be given with a list of all Docker images on your system.
sudo docker images
Remove sudo if you are using windows based environment.
You can also use the “docker image” command with the “ls” parameter. It is important to note that you must write
image rather than
sudo docker image ls
Listing Unused docker images
Some images may be unused by any container. Even those images can be list using the below command.
docker images -a
List docker images by name and tag
docker images [image name]
docker images ubuntu
listing the image by providing the correct tag.
docker images ubuntu:18.04
