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. Related CVEs:
