Hi! We have a Virtual Machine with Docker installed and we have some containers/images/volumes. We are running Jenkins and Rancher as well.
We have been problems with disk space and we just noticed that the docker folder is taking almost all the disk space.
docker volume ls
everything seems to be okay. I can’t see anything that shouldn’t be there.
docker system df, it shows:
Images - Size 3.358GB (Reclaimable 28%)
Containers- Size 46.66MB (Reclaimable 0%)
Local Volumes- Size 44.32MB (Reclaimable 0%)
There is only 28% fo reclaimable disk space. We can also see that Images, Containers and Volumes are taking up to around 3.5GB.
However, when I do
sudo du --max-depth=1 -h | sudo sort -n -r | sudo head -n 20 on
we can see that
./aufs is taking 8.7GB.
Is it secure to do
docker system prune? Will this command free some space from that
Will that command remove, for example,
And another question, which I don’t know if it’s related to Docker: there is an
export folder on the root of the machine. Is it related to Docker whatsoever?
Thanks a lot for the help.
