How can I delete Docker's images?
DockerDocker Problem Overview
I've the following images:
alex@alexvps:~$ sudo docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
<none> <none> 70c0e19168cf 5 days ago 1.069 GB
<none> <none> c2ce80b62174 8 days ago 399.2 MB
<none> <none> 60afe4036d97 8 days ago 325.1 MB
and when I try to remove one of them I get:
alex@alexvps:~$ sudo docker rmi 60afe4036d97
Error: Conflict, 60afe4036d97 wasn't deleted
2014/01/28 00:54:00 Error: failed to remove one or more images
How can I remove them? Why is there such conflict?
Docker Solutions
Solution 1 - Docker
In order to delete all images, use the given command
docker rmi $(docker images -q)
In order to delete all containers, use the given command
docker rm $(docker ps -a -q)
Warning: This will destroy all your images and containers. It will not be possible to restore them!
This solution is provided by Techoverflow.net.
Solution 2 - Docker
Possible reason: The reason can be that this image is currently used by a running container. In such case, you can list running containers, stop the relevant container and then remove the image:
docker ps
docker stop <containerid>
docker rm <containerid>
docker rmi <imageid>
If you cannnot find container by docker ps, you can use this to list all already exited containers and remove them.
docker ps -a | grep 60afe4036d97
docker rm <containerid>
Note: Be careful of deleting all exited containers at once in case you use Volume-Only
containers. These stay in Exit
state, but contains useful data.
Solution 3 - Docker
The reason for the error is that even though the image did not have any tag, there still exists a container created on that image which might be in the exited
state. So you need to ensure that you have stopped and deleted all containers created on those images. The following command helps you in removing all containers that are not running:
docker rm `docker ps -aq --no-trunc --filter "status=exited"`
Now this removes all the dangling non-intermediate <none>
images:
docker rmi `docker images --filter 'dangling=true' -q --no-trunc`
> Note: To stops all running containers:
>
> docker stop docker ps -q
Solution 4 - Docker
In Bash:
for i in `sudo docker images|grep \<none\>|awk '{print $3}'`;do sudo docker rmi $i;done
This will remove all images with name "<none>". I found those images redundant.
Solution 5 - Docker
The image could be currently used by a running container, so you first have to stop and remove the container(s).
docker stop <container-name>
docker rm <container-id>
Then you could try deleting the image:
docker rmi <image-id>
You must be sure that this image doesn't depend on other images (otherwise you must delete them first).
I had a strange case in which I had no more containers still alive (docker ps -a
returned nothing) but I couldn't manage to delete the image and its image-dependency.
To solve these special cases you could force the image removal with this:
docker rmi -f <image-id>
Solution 6 - Docker
I found the answer in this command:
docker images --no-trunc | grep none | awk '{print $3}' | xargs docker rmi
I had your problem when I deleted some images that were being used, and I didn't realise (using docker ps -a
).
Solution 7 - Docker
Since Docker ver. 1.13.0 (January 2017) there's the system prune
command:
$ docker system prune --help
Usage: docker system prune [OPTIONS]
Remove unused data
Options:
-a, --all Remove all unused images not just dangling ones
-f, --force Do not prompt for confirmation
--help Print usage
Solution 8 - Docker
Simply you can aadd --force
at the end of the command. Like:
sudo docker rmi <docker_image_id> --force
To make it more intelligent you can add as:
First stop all running containers.
sudo docker stop $(docker ps | grep <your_container_name> | awk '{print $1}')
Now remove container
sudo docker rm $(docker ps | grep <your_container_name> | awk '{print $1}')
Now as a last step, remove docker image
sudo docker rmi $(docker images | grep <your_image_name> | awk '{print $3}') --force
Here in docker ps
$1 is the first column, i.e. the Docker container ID.
And docker images
$3 is the third column, i.e. the Docker image ID.
Note: In above commands sudo
is used in case you might / might not have privileges to execute command. if it gives you error, try removing sudo
.
Solution 9 - Docker
In addition to Sunny's answer:
In order to delete all images on a Windows machine (with Docker for Windows) in a PowerShell window, do:
docker images -q | %{docker rmi -f $_}
In order to delete all containers on a Windows machine (with Docker for Windows) in a PowerShell window, do:
docker ps -a -q | %{docker rm -f $_}
Solution 10 - Docker
First, remove all the containers using the following command
sudo docker ps -a -q | xargs -n 1 -I {} sudo docker rm {}
Then, remove the image by its ID using the following command
sudo docker rmi <image-id>
Solution 11 - Docker
You have to stop/delete all unnecessary containers created on that images first.
Have a look: https://stackoverflow.com/questions/17236796/how-to-remove-old-docker-io-containers.
After that use @marcell solution.
Solution 12 - Docker
Remove all the containers
docker ps -q -a | xargs docker rm
Force remove all the Docker images
docker rmi -f $(docker images -f dangling=true -q)
Solution 13 - Docker
The most compact version of a command to remove all untagged images is:
docker rmi $(docker images | grep "^<none>" | awk '{print $"3"}')
Solution 14 - Docker
To delete some Docker image you must execute the following command:
$ docker rmi <docker_image_id>
So, to delete all Docker images you can execute the following command:
$ docker rmi $(docker images -q)
Now, if you want delete all Docker images (including images that are in use), you can add the flag -f
, for example:
$ docker rmi -f $(docker images -q)
Solution 15 - Docker
Use
docker image prune -all
or
docker image prune -a
Remove all dangling images. If -a
is specified, it will also remove all images not referenced by any container.
Note: You are prompted for confirmation before the prune removes anything, but you are not shown a list of what will potentially be removed. In addition, docker image ls
does not support negative filtering, so it difficult to predict what images will actually be removed.
As stated under Docker's documentation for prune.
Solution 16 - Docker
If you want to automatically/periodically clean up exited containers and remove images and volumes that aren't in use by a running container you can download the Docker image meltwater/docker-cleanup
.
That way you don't need to go clean it up by hand.
Just run:
docker run -d -v /var/run/docker.sock:/var/run/docker.sock:rw -v /var/lib/docker:/var/lib/docker:rw --restart=unless-stopped meltwater/docker-cleanup:latest
It will run every 30 minutes (or however long you set it using DELAY_TIME=1800 option) and clean up exited containers and images.
More details: https://github.com/meltwater/docker-cleanup/blob/master/README.md
Solution 17 - Docker
I have found a solution with Powershell script that will do it for me.
The script at first stop all containers than remove all containers and then remove images that are named by the user.
