Docker – takes a conservative approach to cleaning up unused objects (often referred to as „garbage collection“) such as images containers volumes and networks these objects are generally not removed unless you explicitly ask Docker to do so this can cause Docker to use extra disk space for each type of object Docker provides a prune command in addition you can use docker system prune to clean up multiple types of objects at once
# docker volume ls
# docker volume rm <volume-name>
# docker volume prune
