Summary

Adds the manifest generation script needed to deploy approver-policy as an operand of cert-manager-operator.

Changes

  • Added hack/update-approver-policy-manifests.sh : renders the upstream cert-manager-approver-policy Helm chart (v0.27.0) into static manifests
  • Makefile : Adds APPROVER_POLICY_VERSION ?= v0.27.0 and wires the script into make update-manifests
  • Generated manifests into bindata/approver-policy/resources/ and config/crd/bases/

Testing

# Regenerate manifests for a given version
make update-manifests APPROVER_POLICY_VERSION=v0.27.0
# Or run the script directly
./hack/update-approver-policy-manifests.sh v0.27.0

Summary by CodeRabbit

  • New Features

    • Added support for cert-manager approver-policy v0.27.0.
    • Introduced the CertificateRequestPolicy resource for defining certificate approval rules, including issuer, namespace, certificate attributes, durations, private keys, and plugins.
    • Added webhook validation, policy enforcement, TLS-secured operation, metrics, and required Kubernetes permissions.
    • Registered the resource with the operator and included installation manifests and a sample policy.
  • Chores

    • Added tooling to update and regenerate approver-policy manifests.

Walkthrough

The operator now generates and embeds cert-manager approver-policy v0.27.0 resources. The change adds the CertificateRequestPolicy CRD, registers it in deployment metadata and samples, and packages approver-policy Kubernetes resources.

Changes

Consider deleting the output directories inside cleanup, or guarding the hardcoded CRD name.

Line 49 deletes one specific CRD file by name. Line 56 then moves every rendered customresourcedefinition_* file into config/crd/bases/. If a future chart version renders a second CRD, line 49 leaves the old file in place and the tree keeps a stale manifest. A glob-based delete keyed to the chart output avoids that drift.

Also applies to: 48-49

Add NetworkPolicy manifests for the approver-policy operand.

This ServiceMonitor adds a scrape path to port 9402 and the Deployment adds a webhook listener on port 10250. The repository already ships per-operand NetworkPolicies for cert-manager and istio-csr under bindata/networkpolicies/. No NetworkPolicy in this cohort selects approver-policy pods.

The existing policies select app.kubernetes.io/instance: cert-manager or app: cert-manager-istio-csr. Approver-policy pods carry app: cert-manager-approver-policy and app.kubernetes.io/instance: cert-manager-approver-policy, so the existing deny-all and allow rules do not apply to them. The new operand therefore runs without the network restrictions the other operands receive.

Add deny-all, metrics-ingress, webhook-ingress, and API-server-egress policies for this operand, to match the existing pattern.

As per path instructions for **/*.{yaml,yml}: "NetworkPolicy defined for the namespace".

"approver-policy-controller" "ApproverPolicy CR" image resources cert-manager

💡 Result:

The approver-policy-controller is a component designed for use with cert-manager that allows administrators to define fine-grained policies—via CertificateRequestPolicy custom resources (CRs)—to restrict and control certificate issuance requests [1][2]. When using this controller, the default built-in approver in cert-manager should be disabled to prevent conflicts, as the approver-policy-controller takes over the responsibility of evaluating and approving CertificateRequests [3][4]. Key points regarding its operation and resources: 1. Controller Configuration: To disable the default cert-manager approver, you typically set the --controllers argument on the cert-manager controller to exclude the certificaterequests-approver controller (e.g., --controllers='*,-certificaterequests-approver') or use the --set disableAutoApproval=true flag in newer versions [3]. 2. Custom Resources (CRs): The core functionality relies on CertificateRequestPolicy resources [2][5]. These policies define the criteria (such as allowed DNS names, IP addresses, or key usages) that a CertificateRequest must meet to be approved [1]. 3. Resource Management: - The controller itself requires specific RBAC permissions to operate, including access to secrets and other cluster resources [1]. - Self-referential deadlocks can occur if the controller's webhook configuration is overly broad (e.g., using wildcard resources like /), which can intercept its own status updates [6]. It is important to ensure that the webhook rules target only the primary resources and not subresources [6]. - When using related components like trust-manager, specific policies may need to be enabled (often via helm chart flags like --set app.webhook.tls.approverPolicy.enabled=true) to allow the auto-approval of required certificates during installation [4][7][8]. For official installation and configuration details, refer to the cert-manager documentation site [6].

🌐 Web query:

site:github.com/cert-manager/approver-policy OR site:cert-manager.io approver-policy "ApproverPolicy" manifest image resources

💡 Result:

approver-policy is a component of cert-manager that automates the approval or denial of CertificateRequests based on user-defined policies [1][2]. These policies are defined using the CertificateRequestPolicy custom resource [1][3]. The core of the system involves defining CertificateRequestPolicy objects, which act as policy profiles [1][4]. When a CertificateRequest is created, approver-policy evaluates it against these profiles to determine whether it should be approved [4]. Key components of the CertificateRequestPolicy include: - selector: Determines which CertificateRequests the policy applies to. It supports selection based on issuerRef and namespace [4]. - allowed: Defines what attributes are permitted in a CertificateRequest [3][5]. - constraints: Additional limitations on the requested certificate [4]. - plugins: Advanced, compile-time built-in approvers used to extend core functionality [3][5]. To enforce these policies, CertificateRequestPolicy resources are bound to Kubernetes users or ServiceAccounts using RBAC. A ClusterRole with the use verb on the certificaterequestpolicies resource must be created and bound to the appropriate subject for the policy to take effect [1]. Regarding deployment and configuration: - Image: The approver-policy component is deployed as a container, and its image configuration is managed via Helm values (e.g., imageRegistry, repository, and tag) [6]. - Resources: Resource limits and requests (CPU/memory) for the pod can be configured in the Helm chart under the resources section [6]. Installation is typically handled via Helm, and administrators must ensure that the appropriate permissions are set for the controller, especially when using external issuers, by specifying the necessary signer names [7].

Wire the approver-policy manifests into reconciliation. The repository registers no approver-policy controller and no production code consumes bindata/approver-policy/resources/*, so the Deployment is not applied. If it is applied later, its image remains quay.io/jetstack/cert-manager-approver-policy:v0.27.0 and resources: {} because no related-image or resource override exists.

In `@pkg/operator/assets/bindata.go` at line 269, Register the approver-policy
controller in the reconciliation flow and consume the manifests under
bindata/approver-policy/resources so the Deployment is applied. Add the
corresponding related-image configuration for cert-manager-approver-policy and
provide the intended resource override instead of leaving resources empty.

Good catch, added the CRD to config/crd/kustomization.yaml and regenerated the bundle with make bundle.

Do we need servicemonitor to be enabled? Will operator create and manage this resource?

For TP I think we can skip that. Removed it and dropped the ServiceMonitor manifest from bindata.

Add the CertificateRequestPolicy metadata to the CSV base.

config/manifests/bases/cert-manager-operator.clusterserviceversion.yaml does not define this owned-CRD entry. make bundle therefore renders only kind, name, and version. Add the entry to the base so generation retains its metadata.

We also need to update operator env vars in config/manager/manager.yaml with the approver-policy image and version. But that would be done as part of deployment reconciliation implementation I guess?

This change reminded me, we need to add the new CRD under owned list in config/manifests/bases/cert-manager-operator.clusterserviceversion.yaml with description, displayName, kind, name, version. Also I am unable recall as part of which changes we used to add an example manifest for each owned CRD. But for this, better to add as part of this change.

That's correct! The ENV vars will be updated as part of controller implementation PR
