Inline comments:
In `@bundles/k8s/manifests/flows.netobserv.io_flowcollectors.yaml`:
- Line 5: Update the controller-gen version annotation in the FlowCollector
manifest to match the Makefile-pinned version, v0.20.0.
In `@config/manager/manager.yaml`:
- Around line 34-35: Pin the default CLI image to reviewed content and render it
consistently across installation paths. In config/manager/manager.yaml (lines
34–35), replace the mutable main tag with the reviewed digest; in
helm/values.yaml (lines 96–97), configure that digest and update the Helm
template to render the digest when set. Regenerate the bundle manifests so their
RELATED_IMAGE_NETOBSERV_CLI and relatedImages entries use the same digest.
In `@docs/e2e-test-consolidated.md`:
- Around line 31-32: Reconcile the step numbering and totals in the consolidated
end-to-end test document: make Phase 1’s listed procedures match its table
count, remove the numbering gap before Step 6, and align the overview total with
the final pass criteria. Update the relevant verification-step sections and
summary counts without adding procedures unless needed to match the documented
total.
- Around line 436-437: Update the networkpolicy checks in both locations to
verify that the returned list contains at least one policy, rather than relying
only on the `kubectl get networkpolicy` exit status; preserve the existing
behavior for non-empty lists.
- Around line 109-110: Update the port checks in the consolidated e2e
instructions, including RULES_DNS and the other affected checks, to inspect the
policy’s .spec.ingress or .spec.egress field according to the expected
direction; do not search the full policy YAML for a port occurrence.
- Line 689: Update the POLICY_YAML check in Step 44 to use a fixed-string or
structured YAML match that reliably detects an empty allow-all egress rule, and
set DENY_CHECK to 1 when one is found.
In `@docs/e2e-test-minimal.md`:
- Line 217: Remove the `bash ./e2e-minimal.sh` self-invocation from the test
blocks in the documentation, so copying them into `e2e-minimal.sh` does not
recursively rerun the script. Keep the run command as an instruction outside the
script contents.
- Line 65: Update the Test 4 check in the OP/PL selector flow to verify the
intended pod membership rather than comparing selector strings; account for
Kubernetes matchLabels AND semantics so the check reports “isolated” only when
the selected pod sets do not overlap.
- Around line 104-105: Update the YAML validation using the YAML variable to
inspect ingress and egress rule structure and reject empty rules as well as the
existing catch-all CIDRs, so the test cannot pass when an empty allow-all rule
is present.
- Line 135: Update the Test 9 no-operand-policies branch to check whether
operand mode is disabled before exiting successfully; when operand mode is
enabled and no policies exist, report the test as failed rather than skipped.
- Line 147: In Tests 10–12, replace the fixed five-second sleeps with polling
for each expected NetworkPolicy state, using a bounded timeout; preserve the
checks for policy recreation, zero policies, and two policies as applicable.
In `@docs/OnDemandCapture.md`:
- Line 309: Update the `kubectl` examples in `OnDemandCapture.md` to specify the
`netobserv` namespace for the watch command and other namespaced `get`,
`describe`, `delete`, and `port-forward` commands, matching the namespace used
when creating the CR.
- Around line 360-362: Remove the curl download command under “Download all
metrics” and direct readers to the Prometheus metrics destination instead,
consistent with the documented behavior that metrics are not available as a
downloadable file.
- Around line 40-44: Remove the `.spec.filters.namespaces` and
`.spec.filters.podLabelSelector` instructions from the OnDemandCapture
reference, or explicitly mark both filters as rejected by the Go CLI backend so
users do not follow them as supported configuration.
- Around line 324-330: Replace the pod-IP access commands in “Get pod IP from
status” with a Kubernetes port-forward to the actual launcher pod, forwarding
local port 8080 to the file server’s 127.0.0.1:8080 listener. Show users
accessing the results at localhost through the forwarded port, rather than using
the pod IP or status port as a direct address.
In `@internal/controller/ondemandcapture_controller.go`:
- Around line 224-246: Update ensureCaptureAccess and createCLIPod so the
ServiceAccount and CLI pod run in an operator-owned namespace unavailable to
tenants, and disable pod-level token automounting. If the CLI needs credentials,
provide a projected token volume mounted only into the cli container; otherwise
leave credentials unmounted.

Security Misconfiguration

Pin the default CLI image to reviewed content. Both new installation defaults use the mutable main tag. The operator passes this value directly to both containers in each OnDemandCapture pod, which mounts a service-account token and uses the capture CLI role. The capture pod also uses imagePullPolicy: Always, so a later registry update can change the code that runs with those permissions. Pin the image and update the Helm template to render the digest.

Reconcile the verification-step totals.
Phase 1 lists only Step 1, but the table counts five steps. The numbering then jumps to Step 6, and the overview says “65+” while the final criteria say 50. Add the missing steps or correct the counts so the pass criteria match the procedures.

Scope port checks to the expected policy direction.
These searches scan the full policy YAML, so a port under ingress can satisfy an egress check, or vice versa. For example, Step 11 checks port 8443 as ingress, but Step 42 counts any occurrence of 8443 as egress. Inspect .spec.ingress and .spec.egress separately. Kubernetes defines them as distinct rule fields. (kubernetes.io)

Remove the unsupported namespace and pod-label filter instructions.
This reference tells users to set filters.namespaces and filters.podLabelSelector. docs/OnDemandCapture-Go.md states that the Go CLI backend rejects both filters. A user who applies the example at Lines 46–56 gets a validation error instead of a capture. Remove that example or document the rejection.

Set the namespace in the kubectl examples.
The examples create the CR in netobserv, but this watch command omits -n netobserv. If the reader’s current namespace differs, the command cannot find the CR. Add the namespace to the other namespaced get, describe, delete, and port-forward examples in this document too. Kubernetes scopes these commands to the current namespace unless a namespace is supplied. (kubernetes.io)

Replace the direct pod-IP access instructions.
This command advertises http://$POD_IP:$PORT as a result address. docs/OnDemandCapture-Go.md states that the file server listens on 127.0.0.1:8080 and requires a Kubernetes port-forward. Direct pod-IP requests cannot reach that listener. Show port-forward access with the actual launcher pod name instead.

Remove the metrics download command.
docs/OnDemandCapture-Go.md states that metrics remain in Prometheus and produce no downloadable file. This command saves an HTTP response as metrics.tar.gz, so it cannot provide the advertised metrics archive. Direct readers to the metrics destination instead.

Authorization Bypass
Reachability: External
Exploitability: Moderate
CWE: CWE-269 — Improper Privilege Management
Do not bind a tenant-reachable ServiceAccount to netobserv-ondemandcapture-cli.
ensureCaptureAccess creates the ServiceAccount in odc.Namespace, and createCLIPod runs there with AutomountServiceAccountToken: true. The bound ClusterRole grants cross-namespace secret and workload access, RBAC object creation and updates, and privileged SCC use. A user who can create an OnDemandCapture and create or exec into a pod in that namespace can read the mounted token and use these cluster-wide permissions.
Move the ServiceAccount and CLI pod to an operator-owned namespace that denies tenant access, or restrict OnDemandCapture creation to cluster administrators. Set pod-level token automounting to false for containers that do not need credentials, and use a projected token volume mounted only into the cli container; Kubernetes does not provide per-container automounting.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
The duration pattern accepts an empty string, and that value breaks decoding for all OnDemandCaptures.
The pattern ^([0-9]+h)?([0-9]+m)?([0-9]+s)?$ matches "", so the API server stores duration: "". The Go type is *metav1.Duration. Its UnmarshalJSON calls time.ParseDuration(""), which fails. The controller cache then cannot decode the list. The informer for every OnDemandCapture stops syncing, and one bad CR stalls reconciliation for all captures.
Fix the source marker in api/ondemandcapture/v1beta1/ondemandcapture_types.go. Do not edit this generated file. Then run make update-bundle to regenerate bundles/k8s/manifests/netobserv.io_ondemandcaptures.yaml, bundles/openshift/manifests/netobserv.io_ondemandcaptures.yaml, and helm/crds/netobserv.io_ondemandcaptures.yaml.

Reject empty or groups in args.
validateCaptureArgs treats or as a no-op. Trailing, leading, and consecutive or tokens therefore pass validation. A filter such as --port=443 still sets hasFilter, so the packet-capture filter requirement passes. The malformed sequence is then passed to the CLI and may broaden the capture.
Track filters per group. Include packet and structured filters that buildCLIArgs emits before Spec.Args, so a leading or remains valid only when a preceding filter exists.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Validate the spec again before createCLIPod builds argv.
validateSpec runs only in phase "". The Pending phase builds the pod from the current spec through buildCLIArgs. IgnoreStatusChange does not filter spec edits. A spec edit after the status moves to Pending is therefore never validated. This window includes the one-second requeue and any backoff retries after an ensureCaptureAccess or createCLIPod error. An edited args value such as --namespace=kube-system or --output-dir=/tmp is appended after the managed flags and overrides them. The CLI then works in a namespace that handleDeletion never cleans up. Output also no longer goes to the served /output volume.

Here are my suggestions. Let's focus on the API first and then improve the controller

I'm not sure it's super interesting to capture flows / metrics as the operator already do that.
However, since we can put filters on both, and those can be different, let's keep it as is for the PoC and discuss with the team about it.

That should be the same eBPF agent image than the operator one

Why do we need that if we go in the way of refactoring the CLI with golang ?
The CLI args to filters should be handled in the CLI repo only.
From operator repo, we should only manipulate []EBPFFlowFilterRule and []FLPFilterSet imported from FlowCollector and reused in OnDemandCapture

Instead of relying on RequeueAfter we should improve the design:
- Keep the CR and owned-Pod watches.
- Make running reconciliation event-driven:
- Update status only when Pod IP, start time, phase, or error actually changes.
- Return no periodic requeue while the Pod is healthy.
- Let Pod status events detect completion/failure.
- Keep a low-frequency safety resync, such as 1–5 minutes, rather than every 5 seconds. This protects against missed/stale events without constant status writes.
- For TTL:
- On completion, calculate the expiration deadline.
- Use
RequeueAfterfor normal cleanup. - Also enqueue all terminal captures during controller startup or through a periodic scan, so cleanup survives operator restarts.
- Alternatively, add a dedicated cleanup controller/queue keyed by expiration time.

We can keep the pod approach for now but we'll need to conside job instead when we'll figure out how to store the output outside of the collector pod.
A Kubernetes Job would provide useful semantics for the CLI container:
- explicit completion/failure state;
- retry policy via
backoffLimit; - optional
activeDeadlineSeconds; - native
ttlSecondsAfterFinished; - clearer distinction between “capture execution” and “file serving”.
