verify-apply

name	verify-apply
description	Post-apply verification and close-out. Confirm ConfigHub published/applied the Unit (Completed vs Failed), then confirm ArgoCD/Flux pulled the OCI artifact and the cluster converged (read-only argocd/flux/kubectl). Use right after cub-apply, or for: did it actually deploy, is it live, did argo pick it up, close this release out. Not for authoring (use cub-mutate).

verify-apply

Post-apply verification, troubleshooting, and close-out — one skill for the whole arc from "did it land?" to "we're done."

Confirm verbs and flags with cub <verb> --help before composing.

The two questions

cub unit apply returning is not the same as the change being live. With OCI delivery there are two distinct stages, and ConfigHub only owns the first:

1. Did ConfigHub publish/apply succeed? For an OCI Target, apply publishes the Unit's data to ConfigHub's OCI registry and completes immediately (ApplyCompleted = "Published successfully") — there's no "waiting for the cluster" on the ConfigHub side. For a ConfigHub Target, apply writes ConfigHub-native config directly. This stage is answered from ConfigHub (UnitStatus / unit-event).
2. Did ArgoCD/Flux converge the cluster? The GitOps tool pulls the published OCI artifact and rolls it out. ConfigHub does not observe this — verify it out-of-band, read-only, with argocd / flux / kubectl. Runtime failures (ImagePullBackOff, CrashLoopBackOff, probe failures) live entirely here.

cub-apply hands off here immediately after returning.

When to use

• Right after cub-apply returns, always.
• "Did it deploy?" / "is it live?" / "did argo pick it up?" / "prove it converged."
• A publish/apply reported failure, or the user thinks the rollout is stuck.
• "Close this out" / "show me the revision history to file."

Do not load for

• The apply has not run yet — use cub-apply.
• Plain ConfigHub-internal query with no runtime cross-check — use cub-query.
• Rolling back a change — use rollback-revision.

Preflight gates

1. cub auth status succeeds — it contacts the server's /me endpoint to confirm the token is still valid (not just local login state). If it fails, ask the user to run cub auth login (an interactive browser sign-in an agent cannot complete).
2. An apply has been attempted — at least one Apply entry in cub unit-action list <slug> --space <s>. If not, route to cub-apply.
3. For cluster-convergence checks: kubectl config current-context matches the cluster ArgoCD/Flux deploys to, and argocd / flux are authenticated against the right instance. If a layer is unreachable, say so explicitly — don't fake agreement.

Stage 1 — did ConfigHub publish/apply?

ConfigHub exposes apply status in overlapping views. Pick the smallest that answers the question.

Source	Command	What it shows
Unit rollup	cub unit get <slug> --space <s> -o jq=.UnitStatus	Action, ActionResult, Status, SyncStatus, Drift. First look.
Latest event	cub unit get <slug> --space <s> -o jq=.LatestUnitEvent	Last Worker progress record — Action, Result, Status, Message, UnitEventNum.
Full event log	cub unit-event list <slug> --space <s>	Every event for the unit.
Per-event detail	cub unit-event get <slug> <num> --space <s>	Message (the actual error) + a ResourceStatuses table per resource.
Action rollup	cub unit-action list <slug> --space <s>	One final status per action: Completed / Failed / Aborted.

Terminal results worth recognizing:

• Completed / ApplyCompleted — for OCI, the data was published to the registry ("Published successfully (oci)"). The Unit is now available for Argo/Flux to pull — go to Stage 2 to confirm the cluster. For a ConfigHub Target, the config was applied directly.
• Failed / ApplyFailed — the publish/apply itself failed. Message carries the error. Go to "Failed" below.
• Aborted — cancelled via cub unit cancel or superseded by a later apply.

LastActionError is not a real field — read errors from unit-event's Message. For bulk scope, pivot to cub unit list --space <s> --filter platform/apply-not-completed to surface anything whose publish didn't complete.

Failed — read the error

cub unit-event get <slug> <latest-event-num> --space <s>

Message carries it; ResourceStatuses names the resource. Common shapes: schema violation (would be caught by vet-schemas — route to triggers-and-applygates to gate it next time), RBAC on the OCI registry, malformed data. Surface it; route to the right fix skill (cub-mutate for data, cub-apply to re-publish).

Stage 2 — did Argo/Flux converge the cluster?

ConfigHub reports Completed once the artifact is published; whether the cluster actually rolled it out is the GitOps tool's job. Verify it directly, read-only:

For ArgoCD-pulled deployments:

argocd app get <app-name>          # Sync + Health, and the synced revision
argocd app diff <app-name>         # live vs desired
argocd app history <app-name>

For Flux-pulled deployments:

flux get kustomizations
flux get helmreleases
flux logs --kind=Kustomization --name=<name>

Then the cluster itself (where runtime failures surface):

kubectl get <kind> <name> -n <namespace>
kubectl describe <kind> <name> -n <namespace>
kubectl get pods -n <namespace> -l <selector>
kubectl logs <pod> -n <namespace> --previous   # crashlooped pods

Report the broken link in plain English — "ConfigHub published rev 12; Argo synced it; but the checkout pod is in ImagePullBackOff: image ghcr.io/acme/checkout:v1.2.4 not found." Do not mutate — no kubectl rollout restart, no argocd app sync --force, no flux reconcile. If the fix is a data change, hand back to cub-mutate; if a re-publish, cub-apply.

Three-way agreement (optional)

When asked "is everything in sync?", build a three-column table — note ConfigHub's column means published, not "applied to cluster":

Row	ConfigHub (published)	Controller (Argo/Flux)	Cluster
Revision	cub unit get -o jq='.Unit | {head: .HeadRevisionNum, live: .LiveRevisionNum, applied: .LastAppliedRevisionNum}'	argocd app get → Sync revision / flux get → Applied revision	metadata.annotations.confighub.com/RevisionNum
Image	cub function get --space <s> --unit <slug> get-container-image <container>	Argo live manifest	kubectl get <kind> -o jsonpath='{.spec.template.spec.containers[*].image}'
Health	UnitStatus.Status == "Completed" (published)	Argo Healthy / Flux Ready: True	.status.conditions[?(@.type=="Available")].status

Name what disagrees:

• ConfigHub published, controller behind — Argo/Flux hasn't pulled the new OCI artifact yet (sync interval, manual sync, or a broken source). Check the controller.
• Controller synced, cluster not converged — probe failure, image-pull, or RBAC in the cluster.
• Cluster diverges from the published artifact — something mutated the cluster out of band; that's Argo/Flux's reconciliation domain (self-heal / drift detection), not ConfigHub's. Point the user at the controller.

If a column is unreachable (argocd not authenticated, kubectl context mismatch), report it "unknown" — don't assume agreement.

Close the release out

Only when Stage 1 is Completed for the whole scope and (if asked) Stage 2 converged:

1. Surface the revision + --change-desc: cub revision list <slug> --space <s> (the DESCRIPTION column is the audit trail).
2. Show what changed: cub unit diff <slug> --space <s> --from <pre-release-revision> --to LiveRevisionNum.
3. Open review links: cub unit get <slug> --space <s> --web, cub revision list <slug> --space <s> --web.
4. Explicitly stop. Tell the user what landed and which links to file. A further change starts fresh via cub-mutate / cub-apply.

Tool boundary

Read-only end to end. No mutations — including kubectl apply/edit/delete/rollout restart, argocd app sync, flux reconcile, and any non-dry cub unit refresh. The argocd / flux / kubectl reads here are how you verify Stage 2; they never mutate.

If the fix is data → cub-mutate. Another publish → cub-apply. Rollback → rollback-revision.

Stop conditions

• User's intent pivots from verify to fix — hand off, don't mutate.
• A controller or cluster layer is unreachable — report "unknown."
• Scope too broad for a useful table — narrow via --where / --filter / platform/apply-not-completed.
• Close-out preflight fails (any Unit still publishing / Failed / gated / LiveRevisionNum behind HeadRevisionNum) — route back.

Evidence

• cub unit get <slug> --space <s> --web — Unit page (data, published state, revisions, gates, events).
• cub unit-event list <slug> --space <s> — per-apply event stream.
• cub revision list <slug> --space <s> --web — revision history with --change-desc.
• ArgoCD / Flux UIs and kubectl get <kind> <name> -o yaml — cluster-side evidence.
