RHBA-2019:0620 - Bug Fix Advisory

Topic

Red Hat OpenShift Container Platform release 3.10.127 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 3.10.127. See the following advisory for the container images for
this release:

https://access.redhat.com/errata/RHBA-2019:0621

This update fixes the following bugs:

• Playbooks that redeployed master certificates did not update `webconsole` secrets, causing failure to start the `webconsole` after redeployment. Now, `webconsole` secrets are re-created when master certificate playbooks are used and the `webconsole`now works properly. (BZ#1667981)
• The files that implemented log rotation functionality were not copied to the correct `fluentd` directory. As a result, logs were not rotated. Now, the container build inspects the `fluentd` gem to find out where to install the files. The files that implement log rotation are copied to the correct directory for `fluentd` usage. (BZ#1684210)
• The SSL and TLS service uses Diffie-Hellman groups with insufficient strength (a key size less than 2048 bytes). As a result, the keys are more vulnerable. Now, the key strength has been increased and certificates are more secure. (BZ#1686135)
• When a cluster was installed, the user name in the loopback kubeconfig is the same as the host name of the master. Now, the variable in the playbook is changed to a different value. (BZ#1686585)
• Using `MERGE_JSON_LOG=true` would create fields in the record that would cause syntax violations or create too many fields in `Elasticsearch`, causing severe performance problems. Now, users who experience these problems can tune `fluentd` to accommodate their log record fields without errors or `Elasticsearch` performance degradation. (BZ#1686946)
• If an override host name had been set, the sync script generated an error in the sync logs. This has now been resolved and is no longer present in situations where `/etc/sysconfig/KUBELET_HOSTNAME_OVERRIDE` is not present. (BZ#1687803)
• Upgrade playbooks ran several `oc` commands that used resource aliases that may not be immediately available after a restart or other reasons. Now, the `oc` suite of commands uses the fully qualified resource name to avoid potential failure. (BZ#1688452)

All OpenShift Container Platform 3.10 users are advised to upgrade to these
updated packages.
