This advisory contains the RPM packages for Red Hat OpenShift Container Platform 3.11.394. See the following advisory for the container images for this release:
https://access.redhat.com/errata/RHBA-2021:0638
Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes:
https://docs.openshift.com/container-platform/3.11/release_notes/ocp_3_11_release_notes.html
This update fixes the following bugs among others:
* Previously, the restart-cluster playbook did not evaluate the defined cluster size for ops clusters.
This was causing come clusters to never complete their restart. This bug fix passes the logging ops cluster size, allowing restarts of ops clusters to complete successfully. (BZ#1879407)
* Previously, the `openshift_named_certificates` role checked the contents of the `ca-bundle.crt` file during cluster installation. This caused the check to fail during initial installation because the `ca- bundle.crt` file is not yet created in that scenario. This bug fix allows the cluster to skip checking the `ca-bundle.crt` file if it does not exist, resulting in initial installations succeeding. (BZ#1920567)
* Previously, if the `openshift_release` attribute was not set in the Ansible inventory file, the nodes of the cluster would fail during an upgrade. This was caused by the `cluster_facts.yml` file being gathered before the `openshift_release` attribute was defined by the upgrade playbook. Now the `cluster_facts.yml` file is gathered after the `openshift_version` role runs and the `openshift_release` attribute is set, allowing for successful node upgrades. (BZ#1921353)
All OpenShift Container Platform 3.11 users are advised to upgrade to these updated packages and images.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL OpenShift Container Platform 3.11.394 package based on the guidance in RHSA-2021:0637.
