Thanks Dan for your diligence,
A cron job would be perfect. As I know your are busy and I have some spare time, in the meantime if you don't mind, I'll add your add your post at

Hi Jacques and all,
Following a request by Jacques to check on disk space used by Docker on our demo sites server (ofbiz-vm1) I thought I would post the steps followed
in case they were of interest to others.
I opened a root terminal on ofbiz-vm1:
> ssh danwatf...@ofbiz-vm1.apache.org
danwatford@ofbiz-vm1:~$ sudo bash
I then open a byobu session so I can resume working in case of disconnection:
root@ofbiz-vm1:/home/danwatford#byobu
To check on disk space usage for the VM:
root@ofbiz-vm1:/home/danwatford#df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 97G 77G 21G 79% /
devtmpfs 16G 0 16G 0% /dev
tmpfs 16G 88K 16G 1% /dev/shm
tmpfs 3.2G 1.6M 3.2G 1% /run
tmpfs 5.0M 0 5.0M 0% /run/lock
<snip>
To check on disk space used by Docker:
root@ofbiz-vm1:/home/danwatford# docker system df
TYPE TOTAL ACTIVE SIZE RECLAIMABLE
Images 106 6 49.22GB 47.17GB (95%)
Containers 9 8 252.7kB 0B (0%)
Local Volumes 23 23 705.7MB 0B (0%)
Build Cache 0 0 0B 0B
To clean up unused images and containers:
root@ofbiz-vm1:/home/danwatford# 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

Total reclaimed space: 46.36GB
The above command cleaned up 46 GB, mostly from unused cached container images.
We can confirm that disk space has been reclaimed by checking df again:
root@ofbiz-vm1:/home/danwatford# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 97G 30G 68G 31% /
So available disk space increased from 21 GB to 68 GB due to the docker clean
up process.
We should install a cron job to run the clean up automatically.
Dan.
