RHBA-2018:2339 - OpenShift Container Platform 3.6 bug fix update

Synopsis

OpenShift Container Platform 3.6 bug fix update

Type/Severity

Bug Fix Advisory None

Topic

Red Hat OpenShift Container Platform release 3.6.173.0.128 is now available with updates to packages and images that fix several bugs.

Description

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments.

This advisory contains the RPM packages for Red Hat OpenShift Container Platform 3.6.173.0.128. See the following advisory for the container images for this release:

https://access.redhat.com/errata/RHBA-2018:2340

This update fixes the following bugs:

  • The task was failing because the conditional could not be evaluated due to the undefined variable. A conditional check was added to ensure the variable was present before evaluating the remaining conditions. The task would be skipped when using embedded etcd because the task does not apply in that scenario. This issue is now addressed. (BZ#1583530)

  • Recently, cloudResourceSyncManager was implemented, which continuously fetched node addresses from cloud providers. The kubelet then received node addresses from the cloudResourceSyncManager. At the time of node registration or kubelet start, the kubelet fetches node addresses in a blocking loop from cloudResourceSyncManager. The issue was that cloudResourceSyncManager was not started before the kubelet had started fetching node addresses from it for the first time. Due to this, the kubelet got stuck in the blocking loop and never returned. It caused node failures at network level, and no node could be registered. Also, as the kubelet was blocked early, the cloudResourceSyncManager never got a chance to start. The cloudResourceSyncManager is now started early in the kubelet startup process so that the kubelet does not get blocked on it and cloudResourceSyncManager is always started. (BZ#1601749)

All OpenShift Container Platform 3.6 users are advised to upgrade to these updated packages and images.
