By default containers are limited to size 10G. I needed to increase container size. For this I added option to file /etc/docker/daemon.json:
{"storage-driver": "overlay"}
After this I restarted docker. Each container now gets total amount of space available on the mount point.
My main background for a recent years is MySQL DEV/DBA engineer but I’m also participating in wider range of tasks which could be likely called as DataOps/DevOps tasks. You can see my online CV here: http://catyellow.net
