This update fixes the following bugs among others:

  • Previously, pre-flight installer validation for OpenShift Container Platform on OpenStack was performed on the flavor metadata. This could prevent installations to flavors detected as baremetal, which might have the required capacity to complete the installation. This is usually caused by OpenStack administrators not setting the appropriate metadata on their bare metal flavors. Validations are now skipped on flavors detected as baremetal, to prevent incorrect failures from being reported. (BZ#1889416)

  • Previously, there was a broken link on the OperatorHub install page of the web console, which was intended to reference the cluster monitoring documentation. This has been fixed. (BZ#1904600)
