RHBA-2015:1991 - Bug Fix Advisory

Topic

An updated release of Red Hat OpenShift Enterprise 3.0.2.0 is now available with updates to packages that fix a bug.

Description

OpenShift Enterprise by Red Hat is the company's cloud computing Platform-as-a-Service (PaaS) solution designed for on-premise or private cloud deployments.

This update fixes the following bug:

• Due to a bug in Docker 1.8, concurrent image pulls could result in broken images, and pods would fail to deploy. As a workaround until the fix in Docker 1.9 is released, this bug fix includes a Kubernetes patch to make Docker image pulls serialized by default. As a result, pods no longer fail to deploy for this reason. It is important to understand that this only solves the issue for images pulled by the Kubelet; Docker pulls outside of Kubernetes could still trigger the issue. (BZ#1278143)

All OpenShift Enterprise 3 users are advised to upgrade to these updated packages.
