Try cleaning up:
$ docker volume rm $(docker volume ls -qf dangling=true)
List dangling volumes:
$ docker volume ls -qf dangling=true
List all volumes:
$ docker volume ls
2 . Also consider removing all the unused Images.
First get rid of the <none> images
docker rmi $(docker images | grep '^<none>' | awk '{print $3}')
Then if you are using Docker Compose to build Images locally for every project. You will end up with a lot of images usually named like your folder (example if your project folder named sample, you will find images name sample_blablabla). so also consider removing all these images.You could remove them manually with:
docker rmi {image-name}
