Currently some teams in our clusters are creating their own network policies and they may get confused with the new NetworkPolicies we are injecting into their namespaces. They don't have an easy way to identify how such resources are created. + +The common method for such case is to place an ownerReferences to the generated object with the triggering resource's reference (e.g. NamespaceConfig). But this will likely impact the implementation of the NamespaceConfig resources' deletion since Kubernetes itself will also try to delete the owned objects once the owner resource (NamespaceConfig) is removed. + +Other options could be adding an annotation/label. + +**Solution:** +The operator supports identifying operator-generated resources through **manual specification of labels and annotations in templates**. While the operator doesn't automatically inject identifying metadata, users can add labels and annotations to their templates, which are then applied to all created resources. + +**Key Features:** +1. **Manual Metadata Specification**: Users add identifying labels/annotations to templates +2. **Automatic Cleanup**: When namespace labels are removed, operator automatically deletes resources for that namespace +3. **Production-Ready**: This approach is sustainable for production environments - no need to delete entire CRs to remove resources from specific namespaces + +**Recommended Labels and Annotations:** + +**Labels:** +- `app.kubernetes.io/managed-by: namespace-configuration-operator` - Standard Kubernetes label for identifying managed resources +- `rbac.ocp.io/role-type: ` - Custom

https://github.com/redhat-cop/namespace-configuration-operator/issues/134 +2. **Problem**: Operator generating excessive Info logs sent to centralized logging (ELK) +3. **Need**: Ability to configure log level to "error" to reduce log volume + +## Root cause analysis +- **Operator uses zap logger**: The operator uses the `zap` structured logging library +- **Default log level**: Operator was running with default log level (info), which includes: + - Info-level messages (normal operations) + - Debug-level messages (template filtering, reconciliation details) + - Error-level messages (actual errors) +- **No persistent configuration**: Log level was not easily configurable for OLM-managed deployments +- **Environment variable support existed**: `ZAP_LOG_LEVEL` and `ZAP_DEVEL` were supported in `main.go`, but: + - Not documented clearly + - Not easily configurable for OLM-managed deployments + - Would be overwritten when OLM updates the Deployment + +## Solution approach +- **Environment variables**: Use `ZAP_LOG_LEVEL` environment variable to control log level +- **Two configuration methods for OLM-managed deployments**: + 1. **Update Subscription** (OLM-native method) - Add environment variables to Subscription spec.config.env + 2. **Kyverno policy** (Policy-based method) - Create a ClusterPolicy that injects log level environment variables into the Deployment +- **OLM-compatible**: Both methods work with OLM-managed deployments and persist across updates +- **Flexible configuration**: Supports "error", "info", "debug", or numeric levels (0-10) +- **Enhanced logging features**: + - V(1) level logging for skipped resources (groups/namespaces/users that don't match templates) + - V(2) level logging for template filtering details (debug-level template matching) + - Deletion tracking logs (info-level) for resource deletion lifecycle + - Retry success logs (V(1)) for optimistic concurrency conflict resolution + - Structured JSON logging format for ELK integration + +## Key findings +- **Log level options**: + - `"error"` = only errors (minimal logging, reduces ELK volume) + - `"info"` = info and above (recommended for production) + - `"debug"` = debug and above (development) + - `"0-10"` = numeric verbosity levels (e.g., "2" shows template filtering logs) +- **Format control**: `ZAP_DEVEL` controls output format: + - `"false"` = JSON format

live value is "zero-like" (e.g., "0"). + +High‑level approach +- Use JSON Merge Patch semantics to delete fields by setting them to null in the patch. +- Before creating the patch, walk the expected

This instructs Kubernetes to remove those fields. + +Key code changes (summary) +- Added helper addNullFieldsForMissing(expected, actual, patchMap): + - Recursively traverses both objects (as map[string]any). + - For any key missing in expected but present in actual, sets patchMap[key] = nil. + - For nested maps present in both, recurse to find deeper missing keys. +- Added createPatchWithNullFields(expected, actual): + - Builds a patch map containing: + - Differences between expected and actual (as before), and + - Null entries for "present in actual, missing in expected" keys via addNullFieldsForMissing. + - Serializes patch map as application/merge-patch+json. +- Updated reconciliation path to use createPatchWithNullFields so removals are included when applying the patch. + +Why this fixes the bug +- Previously, when a conditional removed a field from the template, the patch often did not request deletion of the stale field. Kubernetes therefore kept the field (with value "0"). +- With the new logic, those missing keys are added as null in the merge patch, which causes Kubernetes to remove them — aligning live state with the rendered template. + +Behavioral guarantees +- Field removal works when a condition flips from true → false. +- Field re‑addition continues to work when the condition flips false → true (expected includes the field again, so the normal patch path adds/updates it). +- Works recursively on nested structures (e.g., spec.hard). + +Notes and considerations +- This approach relies on JSON Merge Patch behavior: setting a key to null deletes it. +- Excluded paths configured by the operator remain respected (no change to exclusion policy). +- Designed to be generic; not limited to ResourceQuota. + +How I wired the forked module (commands) +```bash +# Option A: Track the branch (lightweight) +go get github.com/ephico2real2/operator-utils@fix-issue-194-field-removal-zero-value +go mod tidy + +# Option B: Pin the exact commit using a pseudo-version +go mod edit -replace \ + github.com/redhat-cop/operator-utils=github.com/ephico2real2/operator-utils@v\ +0.0.0-20251208075852-9569465257c1 +go mod tidy + +# Build and run (local) +./build.sh -o bin/manager main.go +./run-go.sh --skip-build +``` + +How the pseudo-version was derived (optional) +```bash +# Get the commit hash used for the fix +cd ../operator-utils-fork +git rev-parse HEAD +# 9569465257c18041b4a4483c90aebfc278882387 + +# Get the UTC timestamp in YYYYMMDDhhmmss +TZ=UTC git show -s --format=%cd --date=format-local:%Y%m%d%H%M%S 9569465257c18041b4a4483c90aebfc278882387 +# 20251208075852 + +# Compose: v0.0.0--<12-char-commit> +# v0.0.0-20251208075852-9569465257c1 +``` + +Appendix: Pseudo-version derivation (step-by-step) + +Short answer on the pseudo-version +- It’s a Go modules pseudo-version composed from the commit’s UTC timestamp and hash: + `v0.0.0-YYYYMMDDHHMMSS-<12-char-commit>` + +How I derived `v0.0.0-20251208075852-9569465257c1` +1) Get the exact commit for the fix: + - `cd /Users/olasumbo/gitRepos/operator-utils-fork` + - `git rev-parse HEAD` + - `9569465257c18041b4a4483c90aebfc278882387` + +2) Get that commit’s UTC timestamp in the required format: + - `TZ=UTC git show -s --format=%cd --date=format-local:%Y%m%d%H%M%S 9569465257c18041b4a4483c90aebfc278882387` + - `20251208075852` + +3) Compose the pseudo-version: + - `v0.0.0-20251208075852-9569465257c1` + - `v0.0.0` because we’re pinning to a commit (no tag baseline) + - `20251208075852` is the UTC commit time + - `9569465257c1` is the first 12 hex chars of the commit + +Tip: you can also let Go generate it by running: +- `go get github.com/ephico2real2/operator-utils@9569465257c18041b4a4483c90aebfc278882387` + and Go will record the matching pseudo-version in go.mod. diff --git a/examples/test-and-logic/ISSUE-194-ROOT-CAUSE-SUMMARY.md b/examples/test-and-logic/ISSUE-194-ROOT-CAUSE-SUMMARY.md new file mode 100644 index 00000000..14c313a7 --- /dev/null +++ b/examples/test-and-logic/ISSUE-194-ROOT-CAUSE-SUMMARY.md @@ -0,0 +1,62 @@ +# Issue #194 — Root Cause Summary + +Problem +- When a conditional stops rendering a field (e.g., ResourceQuota.spec.hard.persistentvolumeclaims), the operator failed to remove the field if its last value was "0".

Applied the test NamespaceConfig: examples/test-and-logic/test-issue-194-field-removal-namespaceconfig.yaml (matches namespaces labeled test-issue-194=true and conditionally includes persistentvolumeclaims: "0"). +2. Verified initial state (no annotation): the field is present and equals 0. +3. Added annotation allow-pvc=true on the test namespace, which makes the template condition false and should remove the field. +4. Observed that the field remained with value "0" (bug). + +How the dependency was identified as the culprit +- Grep showed UpdateLockedResources is not implemented in the operator controllers (no matches in controllers/). +- go doc confirmed UpdateLockedResources is a method of operator-utils’ lockedresourcecontroller.EnforcingReconciler. +- The operator embeds EnforcingReconciler and calls UpdateLockedResources during reconciliation. +- Therefore, the comparison/patch generation that decides whether to add/remove fields lives in the dependency (operator-utils), not in this operator. + +Key findings +- Template rendering in the operator was correct: when allow-pvc=true, the template no longer contained persistentvolumeclaims. +- Despite the field disappearing from the rendered template (expected), the dependency did not emit a deletion for the field that already existed in the live object. +- Net effect: the field persisted with value "0" in the cluster because the patch

evaluated to false) +- **Test Case 5**: No resources created (unexpected - universal template should create resources for all groups) +- **Total Resources Created**: **0** + +⚠️ **Issues Identified**: +- Universal template (Test Case 5) did not create resources as expected +- All templates rendered to empty/null, preventing resource creation +- Error logs show `"Object 'Kind' is missing in 'null'"`

+- Focuses on the operator controller manager deployment + +#### Targets: +- **Pods**: All pods in `namespace-configuration-operator` namespace with `docker.io/*` or `library/*` images +- **Deployments**: The `namespace-configuration-operator-controller-manager` deployment + +#### Prerequisites: +- `dockerhub-secret` must exist in the `namespace-configuration-operator` namespace +-

Hub image pull secret injection with intelligent image detection + +#### What it does: +- Uses Kyverno's `imageRegistry` context to intelligently detect Docker Hub images +- Automatically injects `dockerhub-secret` for any workload using Docker Hub +- Supports all workload types (Deployment, StatefulSet, DaemonSet, ReplicaSet) +- Uses precise image registry detection rather than pattern matching + +#### Key Features: +- **Smart Detection**: Uses `imageData.registry` context for precise matching +- **Broad Coverage**: Handles all Kubernetes workload types +- **Auto-generation**: Supports Kyverno's autogen for controller resources + +#### Targets: +- Any Pod or workload using images from `docker.io` registry +- Handles both explicit `docker.io/` and implicit Docker Hub references + +--- + +### replace-operator-image-to-dockerhub + +**File**: `replace-operator-image-to-dockerhub.yaml` +**Type**: ClusterPolicy +**Purpose**: Force the namespace configuration operator to always use Docker Hub images + +#### What it does: +- Rewrites the operator deployment to use `docker.io/DOCKERHUB_USERNAME/namespace-configuration-operator:latest` +- **Note**: Use the template file (`env-replace-operator-image-to-dockerhub.yaml.tpl`) with `generate-policies.sh` to set your Docker Hub username +- Applies to both Pod and Deployment resources +- Specifically targets the `manager` container +- Automatically injects the required `dockerhub-secret` + +#### Use Cases: +- **Development**: Force use of custom Docker Hub builds +- **Testing**: Override default operator images +- **Air-gapped environments**: Redirect to internal Docker Hub mirror + +#### Targets: +- **Pods**: Direct pods in `namespace-configuration-operator` namespace +- **Deployments**: The `namespace-configuration-operator-controller-manager` deployment + +--- + +### dockerhub-image-replacement + +**File**: `dockerhub-image-replacement.yaml` +**Type**: ClusterPolicy +**Purpose**: Replace Quay.io namespace-configuration-operator images with Docker Hub equivalents + +#### What it does: +- Intercepts any use of `quay.io/*/namespace-configuration-operator` images +- Redirects to `docker.io/DOCKERHUB_USERNAME/namespace-configuration-operator` +- **Note**: Use the template file (`env-dockerhub-image-replacement.yaml.tpl`) with `generate-policies.sh` to set your Docker Hub username +- Handles both tag-based and digest-based image references +- Automatically injects `dockerhub-secret` for authentication + +#### Features: +- **Digest Support**: Handles `sha256:` digest references correctly +- **Tag Support**: Preserves tag names when redirecting +- **Secret Injection**: Automatically adds required pull secrets +- **Comprehensive Coverage**: Handles both initContainers and containers + +#### Use Cases: +- **Registry Migration**: Move from Quay.io to Docker Hub +- **Access Control**: Use Docker Hub when Quay.io access is restricted +- **Cost Optimization**: Avoid Quay.io pull limits + +--- + +### internal-registry-image-replacement + +**File**: `internal-registry-image-replacement.yaml` +**Type**: ClusterPolicy +**Purpose**: Replace Quay.io images with OpenShift internal registry + +#### What it does: +- Redirects `quay.io/redhat-cop/namespace-configuration-operator` to internal registry +- Uses the full internal registry URL: `image-registry.openshift-image-registry.svc.cluster.local:5000` +- Preserves image tags and digests +- No pull secret injection needed (uses internal cluster authentication) + +#### Benefits: +- **No Pull Secrets**: Uses OpenShift's internal authentication +- **Network Efficiency**: Images stay within the cluster +- **Air-gapped Support**: Works without external registry access +- **Cost Savings**: No external registry bandwidth costs + +#### Target Registry: +``` +image-registry.openshift-image-registry.svc.cluster.local:5000/namespace-configuration-operator/namespace-configuration-operator:TAG +``` + +#### No Template Needed: +Unlike Docker Hub policies, this policy uses **fixed, standardized values** that never change: +- **Registry URL**: `image-registry.openshift-image-registry.svc.cluster.local:5000` (standard OpenShift internal registry) +- **Namespace**: `namespace-configuration-operator` (operator's namespace) +- **Image Name**: `namespace-configuration-operator` (operator's image name) + +These values are consistent across all OpenShift clusters, so this policy can be applied directly without any variable substitution or templates. + +--- + +### operator-log-level-config + +**File**: `operator-log-level-config.yaml` +**Type**: ClusterPolicy +**Purpose**: Configure operator log levels via Kyverno mutation (works with OLM-managed deployments) + +#### What it does: +- Injects `ZAP_LOG_LEVEL` and `ZAP_DEVEL` environment variables into the operator Deployment +- Works with OLM-managed deployments (OLM will not revert Kyverno mutations) +- Ensures log level configuration persists across operator updates + +#### Why use this: +- **OLM Constraint**: Direct Deployment edits are reverted by OLM +- **Subscription Alternative**: If Subscription config is not available or preferred +- **Persistent Configuration**: Kyverno mutations survive OLM updates + +#### Configuration: + +**Option 1: Use Template with Environment Variables (Recommended)** +```bash +# Set Docker Hub username (required for other policies, optional for log level policy) +export DOCKERHUB_USERNAME=your-username + +# Set log level environment variables +export ZAP_LOG_LEVEL=info +export ZAP_DEVEL=false + +# Generate all policies from templates (run from repository root) +./local-utilities/generate-policies.sh + +# Apply generated log level policy +oc apply -f kyverno-policies/operator-log-level-config.yaml +``` + +**Option 2: Edit Policy Directly** +Edit the policy file to change log levels: +```yaml +env: +- name: ZAP_LOG_LEVEL + value: "info" # Options: "error", "info", "debug", "0-10" +- name: ZAP_DEVEL + value: "false" # Options: "true" (console), "false" (JSON) +``` + +#### Recommended Settings: +- **Production**: `ZAP_LOG_LEVEL=info`, `ZAP_DEVEL=false` (JSON, info level) +- **Debugging**: `ZAP_LOG_LEVEL=2`, `ZAP_DEVEL=false` (JSON, shows template filtering logs) +- **Development**: `ZAP_LOG_LEVEL=info`, `ZAP_DEVEL=true` (console, human-readable) + +#### Alternative: Subscription Configuration +For OLM-deployed operators, you can also configure log levels via Subscription: +```yaml +apiVersion: operators.coreos.com/v1alpha1 +kind: Subscription +spec: + config: + env: + - name: ZAP_LOG_LEVEL + value: "info" + - name: ZAP_DEVEL + value: "false" +``` + +See [LOG_LEVEL_CONFIGURATION.md](../docs/LOG_LEVEL_CONFIGURATION.md) for detailed documentation. + +--- + +### sample-image-replacement + +**File**: `sample-image-replacement.yaml` +**Type**: ClusterPolicy +**Purpose**: Example policy showing Harbor registry redirection + +#### What it does: +- **Reference
