Docker CE on Ubuntu supports overlay2, aufs and btrfs storage drivers. Note: In Docker Engine - Enterprise, btrfs is only supported on SLES. See the documentation on btrfs for more details. For new installations on version 4 and higher of the Linux kernel, overlay2 is supported and preferred over aufs. Docker CE uses the overlay2 storage driver by default. Docker gives you all the tools you need to clean up your system from the command line. This cheat sheet-style guide provides a quick reference to commands that are useful for freeing disk space and keeping your system organized by removing unused Docker images, containers, and volumes. How to Use This Guide.
regarding bridge networks I find the following modification more robust: In this example I do not want to delete the network named ($2) 'bridge', if I am not mistaken that network is predefined by docker. |
What about pruning the networks https://docs.docker.com/engine/reference/commandline/network_prune/: They seem less distructive. |
@blankdots those are great, but are only available as of 1.13. |
To delete volumes, use: docker volume rm $(docker volume ls -f 'dangling=true') |
I was looking for a clean everything (almost, see EDIT below) not running or in use command to do a clean reset before installing Rancher to manage the entire system (highly recommend watching the demo and trying it out btw!). Hope this comes in handy for someone else looking for a fresh start! You can still use the filtering arguments to prune only resources matching a certain label or before a certain timestamp. Thanks to @blankdots for the suggestion above to look into the EDIT: This does not seem to include removal of unused/dangling volumes, so @professordennis's suggestion is still best to use for that case: |
how to clean it before starting docker? docker cannot be started due to no space. |
just faced an inode exhaustion issue on ext4 & freed up ~18.5 million inodes out of 19 million total inodes using the image cleanup command. |
@thebaconguy If you want to remove volumes with the prune command you can run this command: |
I use tutum/lamp image docker. ( 500 Mo ) Then, i import this file. How i can clean my file and have a good size ( 500 / 600 mo ? ) More Docker command in French : https://www.visionduweb.eu/wiki/index.php?title=Ajouter_Docker_sur_GNU_Linux |
Small comment: first remove the containters, then remove the images. Just a small re-order, but it saves a potential error (as images that are bound to contains cannot be deleted). |
|
I came here to add the same comment as @cies. Running the commands in the order listed always results in me going back to the images command after I run the containers command. |
Stack Overflow: How to clean up Docker is what I was searching when I came here. |
Nice work... what is the best way to clean up a swarm cluster? |
Muito bom! |
Docker got cleanup commands built in now: |
I prepared docker image to automate it. The image delete unused images and conatainers only. |
don't you feel Docker has way too many flags and options... wouldn't be easier if all efforts were focused on docker-composer and restrict the yml configuration leaving the freedom for the dockerfiles? |
|
For docker swarm just create stack: Thanks for this @Monokai, original comment |
But I have tons of old images dating back years ago? EDIT: This worked, |
Not sure, if I think that doesn't work properly. |

Thanks @thaJeztah , very clear! You are always trying to answer my question at first time, really appreciated! |
@gyliu513 you're welcome, glad I could help! |
@thaJeztah 2018 your answer still up to date? has any new options emerged since then? |
@thaJeztah Is there any way available to clean up the log of docker container without stopping the container |
No; no such option; best to configure the max-file / max-size options when creating containers |
Can we at least get the default of max-size set to a sane value like 10M or something? I just noticed I have a 1G log, the container was created years ago! Not sure what's my best course of action now |
