Free up disk space by removing dangling docker images and volumes

https://dev.to/hossein761/free-up-disk-space-by-running-these-docker-commands-2okm

By Hossein Kazemi Feb 13 ・1 min read

If you are using Docker, every now and then your disk gets filled up with dangling docker images and volumes. Simple run the following commands to get rid of them and open up disk space on your machine:

remove dangling images

docker rmi -f $(docker images -f dangling=true -q)

remove dangling volumes

docker volume rm $(docker volume ls -qf dangling=true)

I am starting a newsletter focused on teaching hands-one backend and infrastructure through building micro-projects.

See how much space is used on each drive or directory or path

sudo du -h / -d 1

sudo du -h /var -d 1

sudo du -h /var/lib -d 1

sudo du -h /var/lib/docker -d 1

sudo du -h /var/lib/docker/overlay2 -d 1

Prune Containers and Volumes, then images will be orphaned and can be deleted.

Prune images that now are unneeded, not connected to volumes or containers

df -h

docker image list

docker system df

docker container list

docker image help

docker image prune

df -h

docker volume ls

docker volume help

# Prune unused volumes

docker volume prune

# Prune images that now are unneeded, not connected to volumes or containers

docker image prune -a

df -h

Results!

5 Simple Commands to Clean up Docker

Introduction

Working with Docker can get messy, especially if you are working with it daily. If you’re like me, you are working with multiple applications and creating multiple volumes for each application. It would be nice if there was a simple way to clean up docker. Below are the commands needed to easily clean up unused docker containers, images, volumes, and networks.

Clean up unused Docker Containers

You can choose to delete these containers individually or you can run the following command in your terminal to delete them all at once.

docker container prune

Total reclaimed space: 9.892GB

After you hit the enter key, you’ll get the following warning:

WARNING! This will remove all stopped containers.

Are you sure you want to continue? [y/N]

Typing y and hitting enter will proceed with removing all your unused docker containers. You’ll then get a nice notification that informs you of how much space you saved by pruning your containers.

Clean up unused Docker Images

Unused Docker Images

Portainer screenshot of unused docker images.

In some situations, unused images can pile up quicker than unused containers. This is especially true if you are using Ouroboros or Watchtower to automatically update your running containers and have them set to leave the previous images so you can revert back to one of those images if an update breaks one of your running applications. Images can also pile up quickly if you’ve been browsing the Docker Hub or experimenting with the latest docker images from Linuxserver.io.

To delete all of your unused images at once, you can run the following command in terminal:

docker image prune

docker image prune

root@docker-ubuntu-s-1vcpu-2gb-nyc1-01:~/ap/prune-docker# docker image prune
WARNING! This will remove all dangling images.
Are you sure you want to continue? [y/N] y

Total reclaimed space: 286.9kB

When you run this command you’ll be asked to verify that you want to delete all of your dangling images.

WARNING! This will remove all dangling images.

Are you sure you want to continue? [y/N]

Type y and hit enter, and you’ll be greeted with a satisfying message on how much space you just saved.

Clean up unused Docker Volumes

If you are storing your persistent volume data on your host machine instead of a network file share then the unused volumes on your system can take up a lot of space. Although some volumes are created manually, some containers automatically create volumes when they initially startup. If you delete those containers, the volumes will remain on the system. You can clean up docker volumes by running the following command in your terminal:

docker volume prune

docker volume prune

root@docker-ubuntu-s-1vcpu-2gb-nyc1-01:~/ap/prune-docker# docker volume prune
WARNING! This will remove all local volumes not used by at least one container.
Are you sure you want to continue? [y/N] y

Clean up unused Docker Networks

Unused docker networks do not take up much space on your system but can annoy those who like to keep a tidy docker host. If you want to display all of your docker networks, type the following command:

docker network ls

docker network ls

root@docker-ubuntu-s-1vcpu-2gb-nyc1-01:~/ap/prune-docker# docker network ls
NETWORK ID     NAME                            DRIVER    SCOPE

Once you hit enter you’ll be presented with all of the networks created on your docker host.

In order to clean up docker networks that are not in use by a container then type the following command:

docker network prune

docker network prune

You’ll be asked if you would like to continue:

WARNING! This will remove all networks not used by at least one container.

Are you sure you want to continue? [y/N]

Type y and docker will remove all of the networks that you are not using.

Cleaning up everything at once

The quickest way to clean up docker will clean up all of your unused containers, volumes, images and networks at once. You can clean up your entire host system by typing out the following command in your terminal:

docker system prune

docker system prune 

root@docker-ubuntu-s-1vcpu-2gb-nyc1-01:~/ap/prune-docker# docker system prune 
WARNING! This will remove:
  - all stopped containers
  - all networks not used by at least one container
  - all dangling images
  - all dangling build cache

Are you sure you want to continue? [y/N] y
Deleted Networks:
ping-docker-compose_default
redis-finance-prophet_default

Total reclaimed space: 0B

When you hit enter, you’ll be presented with the following warning:

WARNING! This will remove:

all stopped containers
all networks not used by at least one container
all dangling images
all dangling build cache

Are you sure you want to continue? [y/N] Typing y and hitting enter will remove every unused item in your docker host.

Success!

Running these commands occasionally is a great way to make sure you are not wasting valuable resources on your docker host system. These commands are also the easiest way to remove unused items in bulk. If you are looking for more docker commands, visit 25 basic docker commands for beginners.
