i just download ubuntu with

docker pull ubuntu:16.04

and then i want to install mysql and nginx inside them but has limited size

docker run -d -t --name temporary ubuntu:16.04
winpty docker exec -it temporary bash
df -h

and i got 

root@90215dee6bc7:/# df -h
Filesystem      Size  Used Avail Use% Mounted on
overlay         991M  280M  711M  29% /

If it is for just one container that you are going to create, then:

docker create -it --storage-opt size=20G ubuntu:16.04 /bin/bash



If you want to increase the default base size for your storage driver, then:

dockerd --storage-opt dm.basesize=20G
  • Be sure to then restart your docker daemon systemctl restart docker and you can do the pull and run you were doing before.
