RHBA-2017:0835 - Bug Fix Advisory

Topic

Updated logging-elasticsearch container images that fix one bug and add one enhancement are now available for Red Hat OpenShift Container Platform 3.4.

Description

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

The logging-elasticsearch container image is a component of the OpenShift Container Platform EFK stack. Elasticsearch is an object store allowing indexing and searching of aggregated logs.

This advisory contains the RPM packages for this release. See the following advisory for the container images for this release:

https://access.redhat.com/errata/RHBA-2017:0836

This update fixes the following bug:

• The openshift-elasticsearch-plugin always attempted to create the index. The plug-in could produce a stack trace if the index already existed. This would sometimes occur when the node was drained and the pod was restarted with the same name. The name is used as part of the index causing the error. This bug fix makes the plug-in check for index existence before trying to seed the index. The plug-in now determines that the index exists and no longer produces a stack trace. (BZ#1416210)

In addition, this update adds the following enhancement:

• The amount of noise in the Elasticsearch (ES) logs, as it starts up and due to the cluster not yet being available when trying to seed its initial ACL, is now decreased. This enhancement improves user experience when checking ES logs. As a result, ES no longer throws a stack trace unnecessarily when trying to seed its ACL as the cluster is starting up. (BZ#1371200)

All OpenShift Container Platform 3 users are advised to upgrade to these updated images.
