RHBA-2019:2580 - Bug Fix Advisory

Topic

Red Hat OpenShift Container Platform release 3.11.141 is now available with
updates to packages and images that fix several bugs and add enhancements.

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 3.11.141. See the following advisory for the container images for
this release:

https://access.redhat.com/errata/RHBA-2019:2581

This release fixes the following bugs:

• The use of `oc replace --force` resulted in dependent objects not being properly removed or updated, causing deployment rollouts to fail and be cancelled. Now, the options `--cascade` and `--grace-period` are added to the `oc replace` module. Deployments are properly rolled out when using the `oc replace` command. (BZ#1685074)
• The image pruning process would take too long to complete due to too many images pruned at the same time. Now, Pager is used to prune images more efficiently without hitting the timeout. (BZ#1702346)
• The OpenShift CA certificate was not copied to the nodes or added to the trust root. As a result, using an endpoint that used SSL communication would fail. To resolve this, run the following commands:

+

• ---

# cp /etc/origin/master/ca.crt /etc/pki/ca-trust/source/anchors/
# update-ca-trust

• ---

This will provide SSL communication to Openshift endpoints. (BZ#1717428)

• Master-controller logs would fill with `The resourceVersion for the provided watch is too old` messages. Logging level has been changed to informational only, resulting in less verbose logging. (BZ#1731187)
• When deploying logging and specifying gluster as the dynamic storage provider, generated PV's were missing storage-class. This was due to the `openshift_logging_es_pvc_dynamic` variable not being passed to the role during PVC generation. Now the `openshift_logging_es_pvc_dynamic` is passed explicitly and templates receive their storage class value and the PVC is correctly generated. (BZ#1732154)
• The webconsole Liveness probe used the curl command for a periodic health check, which caused an unusually high level of dentry cache usage. This could cause high CPU usage when draining nodes. The Liveness probe has been changed to avoid excessive dentry cache usage. (BZ#1735751)
• Fluentd did not look for continuation log lines from the Docker json-file or journald log driver. As a result, very long log lines were split in Elasticsearch and Kibana. Now, fluentd has been changed to look for continuation log lines and reconstruct them before sending it to Elasticsearch. (BZ#1740263)
• Upgrades would fail due to `openshift_control_plane : Wait for /apis/servicecatalog.k8s.io/v1beta1 when registered` errors. This was due to ServiceCatalog API endpoints not responding before the timeout. Now, the timeout has been increased and control plane upgrades are successful. (BZ#1742002)

This release includes the following enhancements:

• Ansible 2.8+ is now supported. (BZ#1740842)

All OpenShift Container Platform 3.11 users are advised to upgrade to these
updated packages and images.
