cert-manager Operator for Red Hat OpenShift release notes

Previously, in a multi-architecture environment, the cert-manager Operator pods were prone to failures because of the invalid node affinity configuration. With this fix, the cert-manager Operator pods run without any failures. (OCPBUGS-19446)

Previously, you could not configure the CPU and memory requests and limits for the cert-manager components such as cert-manager controller, CA injector, and Webhook. Now, you can configure the CPU and memory requests and limits for the cert-manager components by using the command-line interface (CLI). For more information, see Overriding CPU and memory limits for the cert-manager components. (OCPBUGS-13830)

Previously, if you updated the ClusterIssuer object, the cert-manager Operator for Red Hat OpenShift could not verify and update the change in the cluster issuer. Now, if you modify the ClusterIssuer object, the cert-manager Operator for Red Hat OpenShift verifies the ACME account registration and updates the change. (OCPBUGS-8210)

Previously, the cert-manager Operator for Red Hat OpenShift did not support enabling the --enable-certificate-owner-ref flag. Now, the cert-manager Operator for Red Hat OpenShift supports enabling the --enable-certificate-owner-ref flag by adding the spec.controllerConfig.overrideArgs field in the cluster object. After enabling the --enable-certificate-owner-ref flag, cert-manager can automatically delete the secret when the Certificate resource is removed from the cluster. For more information on enabling the --enable-certificate-owner-ref flag and deleting the TLS secret automatically, see Deleting a TLS secret automatically upon Certificate removal (CM-98)

Previously, the cert-manager Operator for Red Hat OpenShift could not pull the jetstack-cert-manager-container-v1.12.4-1 image. The cert-manager controller, CA injector, and Webhook pods were stuck in the ImagePullBackOff state. Now, the cert-manager Operator for Red Hat OpenShift pulls the jetstack-cert-manager-container-v1.12.4-1 image to run the cert-manager controller, CA injector, and Webhook pods successfully. (OCPBUGS-19986)

Previously, the cert-manager Operator for Red Hat OpenShift did not allow you to install older versions of the cert-manager Operator for Red Hat OpenShift. Now, you can install older versions of the cert-manager Operator for Red Hat OpenShift using the web console or the command-line interface (CLI). For more information on how to use the web console to install older versions, see Installing the cert-manager Operator for Red Hat OpenShift. (OCPBUGS-16393)

Previously, the cm-acme-http-solver pod did not use the latest published Red Hat image registry.redhat.io/cert-manager/jetstack-cert-manager-acmesolver-rhel9. With this release, the cm-acme-http-solver pod uses the latest published Red Hat image registry.redhat.io/cert-manager/jetstack-cert-manager-acmesolver-rhel9. (OCPBUGS-10821)

Previously, the cert-manager Operator for Red Hat OpenShift did not support changing labels for cert-manager pods such as controller, CA injector, and Webhook pods. With this release, you can add labels to cert-manager pods. (OCPBUGS-8466)

Previously, you could not update the log verbosity level in the cert-manager Operator for Red Hat OpenShift. You can now update the log verbosity level by using an environmental variable OPERATOR_LOG_LEVEL in its subscription resource. (OCPBUGS-9994)

Previously, 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 was not uninstalled properly. The cert-manager Operator for Red Hat OpenShift is now properly uninstalled. (OCPBUGS-9960)

Previously, the cert-manager Operator for Red Hat OpenShift did not support using Google workload identity federation. The cert-manager Operator for Red Hat OpenShift now supports using Google workload identity federation. (OCPBUGS-9998)

After installing the cert-manager Operator for Red Hat OpenShift, if you navigate to Operators → Installed Operators and select Operator details in the OpenShift Container Platform web console, you cannot see the cert-manager resources that are created across all namespaces. As a workaround, you can navigate to Home → API Explorer to see the cert-manager resources. (OCPBUGS-11647)

After uninstalling the cert-manager Operator for Red Hat OpenShift by using the web console, the cert-manager Operator for Red Hat OpenShift does not remove the cert-manager controller, CA injector, and Webhook pods automatically from the cert-manager namespace. As a workaround, you can manually delete the cert-manager controller, CA injector, and Webhook pod deployments present in the cert-manager namespace. (OCPBUGS-13679)

The following issuer types are supported:

The following ACME challenge types are supported:

The following DNS-01 providers for ACME issuers are supported:

The cert-manager Operator for Red Hat OpenShift now supports injecting custom CA certificates and propagating cluster-wide egress proxy environment variables.

You can customize the cert-manager Operator for Red Hat OpenShift API fields by overriding environment variables and arguments. For more information, see Customizing cert-manager Operator API fields

You can enable monitoring and metrics collection for the cert-manager Operator for Red Hat OpenShift by using a service monitor to perform the custom metrics scraping. After you have enabled monitoring for the cert-manager Operator for Red Hat OpenShift, you can query its metrics by using the OpenShift Container Platform web console. For more information, see Enabling monitoring for the cert-manager Operator for Red Hat OpenShift

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

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)

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.
