From 1010a59439c393a02f3e1078b0e864e49242d4f3 Mon Sep 17 00:00:00 2001 From: stxkxs <139715017+stxkxs@users.noreply.github.com> Date: Sun, 9 Aug 2026 10:36:55 -0700 Subject: [PATCH] fix: the ops platform declared an AgentFleet the API server refuses MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `addons/ai-platform/agent-platform/base/platform.yaml` shipped an AgentFleet whose single agent carried name, systemPrompt and modelRoute. The AgentFleet CRD requires `spec.agents[].image`, and it has no default, so every cluster syncing this addon got AgentFleet.agents.nanohype.dev "ops-fleet" is invalid: spec.agents[0].image: Required value and the Application never reached Healthy. This manifest is in the base — it is applied to every cluster in the fleet. `image` is the container the agent actually runs, and it is the tenant's own build. This catalog has nothing truthful to put there: nothing in the org publishes a generic agent, and agentctl's own scaffold writes the literal REPLACE_WITH_YOUR_AGENT_IMAGE for a human to fill in. So the fleet is gone rather than patched. The EvalSuite went with it, deliberately rather than incidentally: its `agentFleetRef` had nothing left to point at, and an EvalSuite over an absent fleet is the same shape of problem one layer up. The eval alerts and the eval-quality dashboard therefore start empty, which is the honest state for a cluster running no agents. AgentEvalNeverRan carries noDataState: OK, so an empty catalog is silent rather than alarming. ─── why nothing caught it ─── Platform, Tenant, ModelGateway, BudgetPolicy, AgentFleet and EvalSuite are on `kubeconform-scan.sh`'s skip list. That skip is honest about why — their schemas are published to no public catalog — and says these kinds are validated "out-of-band" with `kubectl apply --dry-run=server`. For this manifest that never happened. A skip that records a gap beats a green tick that pretends there is none, but a gap nobody closes is still a gap. `scripts/check-platform-crs.py` closes it without a cluster. It resolves the CRDs from the operator chart at the version this catalog PINS — read out of addons-agent-operator's targetRevision, not `latest`, because the question is whether the manifest is valid against the CRDs this catalog installs — and walks every CR of those kinds: required present at every level, nothing excess, arrays transparent. Run against the manifest as it shipped, it fails naming `spec.agents[0].image`. ─── one thing the gate had to be taught ─── Its first pass also reported the ops Tenant as refused over `spec.primaryPersona`. That was wrong, and the correction is the interesting part: structural-schema defaulting runs BEFORE validation, so a required property carrying a `default` is filled in by the API server and admitted. `primaryPersona` defaults to `generic`; `image` has no default. Reading `required` alone cannot tell those apart, and a gate that cries wolf about a manifest running on every cluster today would not survive its first week. --- .github/workflows/ci.yml | 23 ++ .../agent-platform/base/platform.yaml | 100 ++---- dashboards/base/alerting/agent-platform.yaml | 21 +- scripts/check-platform-crs.py | 293 ++++++++++++++++++ 4 files changed, 352 insertions(+), 85 deletions(-) create mode 100755 scripts/check-platform-crs.py diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 9d939a9..aea1e2a 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -123,6 +123,28 @@ jobs: - name: Every pod names a ServiceAccount its chart creates run: ./scripts/check-serviceaccount-bindings.py + platform-crs: + name: the catalog's own CRs are admissible + runs-on: ubuntu-latest + steps: + - name: Checkout + uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 # v7 + - name: Install helm + uses: azure/setup-helm@9bc31f4ebc9c6b171d7bfbaa5d006ae7abdb4310 # v5 + - name: Install pyyaml + run: pip install pyyaml + # The platform's own CRDs are on kubeconform-scan.sh's skip list — their + # schemas are published to no public catalog — and that skip's comment says + # these kinds are validated out-of-band against a real webhook.
