Description Vikram Goyal 2016-03-03 05:43:48 UTC

In 7.2.3, the default rootfs size is set to (10 or 20 GB).

Document for this user story:

* the default rootfs size
* how to set the container rootfs size as a docker CLI option
* mention that the user can only increase the size and not decrease it

Not everything mentioned in the Trello card has been implemented yet, so I documented it as it is today.

@yoana, I clicked on the link and did not see your changes. What am I missing.

Shishir, can you please also review the changes.

Closing this bug. Vivek, reopen if the text needs more work. If it needs substantial rework or there are new features, please open a new bug for 7.2.6.
