    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.
