Bug Fix Advisory docker bug fix and enhancement update

Advisory: RHBA-2016:0536-1
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2016-03-31
Last updated on: 2016-03-31
Affected Products: Red Hat Enterprise Linux Extras (v. 7)


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

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

The docker packages have been upgraded to upstream version 1.9.1, which provides
a number of bug fixes and enhancements over the previous version. (BZ1286806)

This update also fixes the following bugs:

* The docker daemon constantly writes to stdout and stderr inside of its unit
file. The systemd-journald writes this stdout and stderr content to the journal.
If the journal is restarted, this results in the docker daemon getting a SIGPIPE
signal. As a consequence, when the docker daemon receives a SIGPIPE signal it
shuts down stopping all containers. To fix this bug, a helper program has been
added that will capture stdout and stderr from docker and forward the content to
the journal. This helper program has improved handling of the SIGPIPE signal. As
a result, if systemd-journal is restarted, then the docker daemon will no longer
shut down, stopping all containers. (BZ#1300076)

* In previous versions of the docker packages, the docker daemon could hang when
pulling multiple container images in parallel. As a consequence, this caused
OpenShift to fail to deploy PODS in production. This bugs has been fixed and now
OpenShift is able to deploy all of its POD's images. (BZ#1256877)

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


Before applying this update, make sure all previously released errata
relevant to your system have been applied.
