RHBA-2015:1782 - Bug Fix Advisory

Topic

Updated docker packages that fix several bugs and add various enhancements are
now available for Red Hat Enterprise Linux 7 Extras.

Description

Docker is an open source engine that automates the deployment of any application
as a lightweight, portable, self-sufficient container that will run virtually
anywhere.

The docker packages have been upgraded to upstream version 1.7.1, which provides
a number of bug fixes and enhancements over the previous version. (BZ#1254315)

This update also fixes the following bugs:

• Previously, when executing parallel instances of the "docker pull" command

from a common container image, the image pool became unresponsive and pulling
the image failed. This bug has been fixed and executing parallel "docker pull"
commands work as expected. (BZ#1252421)

• Setting up the DATA_SIZE option in the /etc/sysconfig/docker-storage-setup

file failed with an error when trying to specify a size with either megabytes or
gigabytes (for example DATA_SIZE=5G). This bug has been fixed and now using
DATA_SIZE passes the correct string to LVM and sets up the volumes successfully.
(BZ#1255874)

Users of docker are advised to upgrade to these updated packages, which fix
these bugs.
