Bug fixes

  • Previously, the unsupportedConfigOverrides field replaced user-provided arguments instead of appending them. Now, the unsupportedConfigOverrides field properly appends user-provided arguments. (CM-23)

    Using the unsupportedConfigOverrides section to modify the configuration of an Operator is unsupported and might block cluster upgrades.

  • Previously, the cert-manager Operator for Red Hat OpenShift was installed as a cluster Operator. With this release, the cert-manager Operator for Red Hat OpenShift is now properly installed as an OLM Operator. (CM-35)

Known issues

  • Using Route objects is not fully supported. Currently, to use cert-manager Operator for Red Hat OpenShift with Routes, users must create Ingress objects, which are translated to Route objects by the Ingress-to-Route Controller. (CM-16)

  • The cert-manager Operator for Red Hat OpenShift does not support using Azure Active Directory (Azure AD) pod identities to assign a managed identity to a pod. As a workaround, you can use a service principal to assign a managed identity. (OCPBUGS-8665)

  • The cert-manager Operator for Red Hat OpenShift does not support using Google workload identity federation. (OCPBUGS-9998)

  • When uninstalling the cert-manager Operator for Red Hat OpenShift, if you select the Delete all operand instances for this operator checkbox in the OpenShift Container Platform web console, the Operator is not uninstalled properly. As a workaround, do not select this checkbox when uninstalling the cert-manager Operator for Red Hat OpenShift. (OCPBUGS-9960)
