Clickable: docker images accumulate on my hard drive

[Aloys]

Hi,

The docker images, used for Clickable, accumulates on my hard drive and I run out of space!
I run Kubuntu 20.04 on a disk of 120GB, and I have another larger disk for my /home.
Until now I did not care where this images where stored, and I was a bit surprised to run out of space.
Docker images are stored in /var/lib/docker so they uses space on my 120GB disk.
And I have many images:

XXX@XXX:~$ docker image ls

I do not know exactly which ones I shall keep, so I will delete all of them (by using the appropriate docker commands), and then do a clickable update to reload required images.

So no question, just to share, but I will be interested if anyone has recommendation, or info to better handle this.

[Aloys]

To erase docker images, I use docker command rmi, for example for IMAGE ID = 4b671c33afef

docker rmi 4b671c33afef

Then, after deleting all images, doing clickable update does nothing!

But just build your app with clickable or clickable desktop and images are reloaded.
This gives:

docker image ls
REPOSITORY                    TAG       IMAGE ID       CREATED       SIZE

@aloys I just do

$ docker system prune

to delete all the images at once.

I use this to delete all unused images in a month.

sudo docker rmi $(docker images -a | grep "month" | awk '{print $3}')
