Subject: [PATCH 01/24] kubectl yconverge: declarative checks/waits and new
 label support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

kubectl plugin that wraps kustomize apply with idempotent converge-mode
label routing (create, replace, serverside, serverside-force) and
post-apply checks defined in yconverge.cue files using a CUE schema.

Check types: #Wait (kubectl wait), #Rollout (rollout status), #Exec
(arbitrary command with retry-until-timeout). Checks are defined per
kustomization in a yconverge.cue file; the framework finds them via
1-level single-directory indirection through kustomization.yaml
resources, ignoring sibling file resources.

Dependency resolution walks CUE imports to build a topological apply
order. Shared check definitions live in pure-CUE packages (no
kustomization.yaml) that the dep walker ignores.

Modes: apply (default), --diff=true, --checks-only, --print-deps.
Apply modifiers: --dry-run=server|none, --skip-checks. Dry-run
forwards to both kubectl apply and delete so replace-mode resources
are provably non-mutating. Invalid flag combinations fail up front.

Namespace for checks resolves from: -n CLI arg > outer kustomization
namespace > indirected base namespace > context default. Exported as
$NS_GUESS for exec checks alongside $CONTEXT.

Error tolerance uses exact criteria: each kubectl step declares the
specific error substrings it tolerates (AlreadyExists, no objects
passed to apply, No resources found) — anything else surfaces raw.

Integration tests run a kwok cluster in Docker with a fake node for
pod scheduling. Covers: schema validation, dep resolution, indirection,
converge-mode labels, broken-cue rejection, --skip-checks negative,
replace-mode dry-run UID preservation, shared checks across db variants
(single/distributed), and a PDB safety check demonstrating prod→qa
failure detection.

CI workflow renamed from "lint" to "checks" to reflect the itest job.

Subject: [PATCH 02/24] yconverge: remove dead schema fields, add dep-ordering
 test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove `up` and `namespaceGuess` from verify.#Step. Both were
"set by the engine, not by user CUE files" — but the engine never
set them either. `up` was designed for a CUE-native orchestrator
where CUE's evaluation order needed a data dependency to serialize
steps; the shell-based dep walker serializes via a for-loop instead.
`namespaceGuess` is handled entirely as the shell variable $NS_GUESS.
No yconverge.cue file in the repo references either field.

New test: verify dependency checks serialize before downstream steps.
Captures the multi-step output of example-with-dependency and asserts
line ordering — namespace check completes before configmap step starts,
configmap check completes before with-dependency step starts. This is
the guarantee `up` was meant to provide, now proven by the shell
execution model.

Subject: [PATCH 04/24] Provisioner always sets up Gateway API, remove from
 functional DAG
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Provisioners (qemu, k3d) run kubectl yconverge for gateway-api and
gateway before --skip-converge exit. Gateway API is infrastructure
assumed present by all functional bases.

Remove gateway imports from 29-y-kustomize and 20-gateway DAG.
Keep all Traefik checks in 40-kafka-ystack — they verify the
complete path kustomize uses for HTTP resources.

Use -write instead of --ensure for /etc/hosts to fix stale entries
from previous provisioner sessions.

E2e: replace y-cluster-provision reprovision with explicit yconverge
calls for monitoring and idempotency proof.

Subject: [PATCH 05/24] Add /etc/hosts update to y-kustomize step (after
 HTTPRoute exists)

The gateway step's /etc/hosts update runs before any HTTPRoutes exist.
The y-kustomize step creates an HTTPRoute, so /etc/hosts needs updating
afterward for kustomize HTTP resource resolution.

Subject: [PATCH 06/24] Use kustomize-identical URLs for y-kustomize content
 checks

Replace API proxy checks (kubectl get --raw .../proxy/...) with curl
checks using the exact URL that kustomize HTTP resources reference:
  http://y-kustomize.ystack.svc.cluster.local/v1/.../base-for-annotations.yaml

This is the path kustomize actually uses. If curl succeeds, kustomize
will resolve the resource. The API proxy path has different failure
modes (endpoint readiness timing) that don't predict kustomize success.

30-blobs-ystack: add blobs content check after restart (was missing).
40-kafka-ystack: kafka base gets 120s timeout (newly mounted secret),
  blobs base gets 60s (already mounted from previous step).

Subject: [PATCH 07/24] Fix /etc/hosts clearing: guard against empty write,
 reduce timeouts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The y-k8s-ingress-hosts -write command replaces the managed block in
/etc/hosts. When called before HTTPRoutes exist (during provisioning),
it wrote an empty block — clearing previous entries. This caused curl
checks to fail with "Could not resolve host" instead of the assumed
secret propagation delay.

Fix: skip -write when no ingress/gateway entries are found, preserving
existing /etc/hosts entries from earlier steps.

With /etc/hosts stable, y-kustomize restart + content availability
takes ~4 seconds (secret volume is fresh on new pod). Reduce check
timeouts from 120s to 30s.

Root cause confirmed: Kubernetes secret volume mounts are instant on
new pods. The 60-120s delay from docs applies only to volume UPDATES
on running pods (kubelet sync interval). Restarts create new pods
with fresh mounts.

+# Monitoring infrastructure setup TODO
+
+Tracks remaining work to fully converge the monitoring stack on vanilla Prometheus v3.
+Ref: PR #67 review comments.
+
+## Converge prerequisite for e2e
+
+The `httproute prometheus-now` validation check requires the full converge sequence.
+Run `y-cluster-converge-ystack --context=local` (or the relevant context) to apply all
+steps including `09-prometheus-httproute`. The validate script only asserts state — it
+does not create resources.
+
+## Remaining tasks
+
+- [ ] Drop `monitoring/prometheus-operator/` once all clusters run vanilla Prometheus
+- [ ] Drop `monitoring/kube-state-metrics/` (operator CRD variant) in favor of `kube-state-metrics-now/`
+- [ ] Drop `monitoring/node-exporter/node-exporter-podmonitor.yaml` — the PodMonitor CRD
+      is only used by the operator; vanilla Prometheus discovers via the `metrics` port convention
+- [ ] Update `k3s/30-monitoring-operator/` — either remove or gate behind a feature flag
+- [ ] Migrate `monitoring/grafana/grafana-service.yaml` annotations (`prometheus.io/scrape`)
+      to also expose a port named `metrics` for consistency with the pod SD convention
+- [ ] Fix `k3s/09-prometheus-httproute/kustomization.yaml` — uses deprecated `bases:` key,
+      should be `resources:`
+- [ ] Add persistent volume for Prometheus data (currently `emptyDir {}`)
+- [ ] Wire up Alertmanager to the converge and validate scripts

Subject: [PATCH 08/24] Replace static-web-server with purpose-built Go
 y-kustomize
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The new y-kustomize binary watches secrets labeled
yolean.se/module-part=y-kustomize via the Kubernetes API and serves
their content at /v1/{group}/{name}/{key}. Secret changes are
reflected instantly — no pod restart or kubelet volume sync needed.

This eliminates the dual-restart problem where the second restart
lost the first secret's volume mount for 60-120s due to kubelet's
sync interval.

Changes:
- y-kustomize/cmd/: Go binary with secret watch, HTTP server, tests
- y-kustomize/rbac.yaml: ServiceAccount + Role for secret list/watch
- y-kustomize/deployment.yaml: new image, removed volume mounts
- Secret labels: yolean.se/module-part changed from config to y-kustomize
- Init secrets get the label for consistent watch matching
- blobs-ystack/kafka-ystack: remove restart checks, keep content checks

Subject: [PATCH 09/24] Add contain v0.8.0 to y-bin, local build for
 y-kustomize image
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

contain: Go binary from turbokube/contain releases, added to
y-bin.runner.yaml with y-contain wrapper.

y-kustomize build:
  contain.yaml: distroless/static:nonroot base, single Go binary layer
  skaffold.yaml: custom builder using go build + contain, OCI output
  No Docker required. No push for local dev.

y-image-cache-load: add help section, fix lint warnings.

Local workflow:
  cd y-kustomize/cmd
  go build + contain build → target-oci/
  y-image-cache-load to get into cluster

CI workflow:
  Same contain.yaml with --push for ghcr.io

Subject: [PATCH 10/24] Fix init secrets to use create-mode, add qemu to
 y-cluster-local-ctr
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Init secrets get yolean.se/converge-mode: create label so re-converge
doesn't overwrite secrets that have been populated by blobs-ystack
or kafka-ystack. The watch-based y-kustomize reacts to secret content
changes — empty secrets cause 404.

y-cluster-local-ctr: add qemu case using SSH, matching the provisioner's
existing SSH connection pattern.

Subject: [PATCH 11/24] Remove 09-y-kustomize-secrets-init
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The watch-based y-kustomize reads secrets via the Kubernetes API.
It doesn't need empty placeholder secrets to start — it starts with
an empty file map and picks up secrets as they're created by
blobs-ystack and kafka-ystack.

Removes the init step and the dependency from 29-y-kustomize.

Subject: [PATCH 12/24] CI: build y-kustomize image on push, temporarily
 include branch

Adds y-kustomize job to images workflow:
  go build + contain build --push to ghcr.io/yolean/y-kustomize:$SHA

Temporarily triggers on y-converge-checks-dag branch pushes.
Push will fail on YoleanAgents fork (no ghcr.io/yolean write access)
but validates the build succeeds.

Subject: [PATCH 14/24] skaffold.yaml for y-kustomize dev loop with contain +
 ctr import

Custom builder: go build + contain tarball + ctr import into cluster.
Deploy hook restarts y-kustomize after image load.
No Docker daemon needed.

Subject: [PATCH 15/24] Restore clean env in e2e, increase registry rollout
 timeout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Restore env -i for acceptance test reproducibility.

Registry rollout timeout increased to 120s — first deploy pulls
the image from ghcr.io which can exceed 60s on cold cache.

The registry timeout was a transient issue, not a real problem.
Restore clean env (env -i) for acceptance test reproducibility.

e2e passes: 36/36 checks with clean env on fresh cluster.

Subject: [PATCH 17/24] Fix provisioner gateway setup: cd to YSTACK_HOME for
 relative paths

kubectl-yconverge resolves k3s/ paths relative to cwd. Provisioners
are called from other repos (checkit) where k3s/ doesn't exist.
Use subshell cd to ensure correct path resolution.

Subject: [PATCH 18/24] Fix kubeconfig null lists after teardown (kubie
 compatibility)

kubectl writes contexts/clusters/users: null instead of [] when the
last item is removed. kubie rejects this as invalid YAML. Fix by
replacing null with empty list after context deletion.

Subject: [PATCH 19/24] Add --converge flag with image caching passthrough

y-cluster-converge-ystack accepts --converge=LIST (comma-separated
base names without number prefix). Replaces the broken --exclude flag.
Default: y-kustomize,blobs,builds-registry. Both provisioners pass
--converge and --dry-run through.

y-image-list-ystack and y-image-cache-ystack accept the same flag.
The provisioner passes its converge targets so all images are pre-cached.

Subject: [PATCH 20/24] Upgrade k3s to v1.35.3, use ClusterIPs for registry
 mirrors

y-registry-config reads magic ClusterIPs from the source-of-truth
YAML files instead of using hostnames. Containerd resolves registries
without /etc/hosts hacks on nodes. Qemu provisioner verifies registry
access after converge.

Subject: [PATCH 23/24] Add kustomize-traverse v0.1.0, replace CUE lookup
 heuristic

kustomize-traverse walks kustomization directory trees using the
kustomize API types. Replaces the bash _find_cue_dir single-dir
heuristic with full tree traversal. Checks from all bases are
aggregated. Also used for namespace resolution.

Subject: [PATCH 24/24] Address PR review: error handling, DX, cleanup

- Remove workflow test changes from images.yaml
- Remove --dry-run from provisioners (use y-cluster-converge-ystack directly)
- Remove kubie null workaround from qemu teardown
- Use absolute paths for yconverge calls (no cd to YSTACK_HOME)
- y-image-list-ystack: let kustomize errors propagate
- kubectl-yconverge: replace grep -c with wc -l, guard file existence
  in _find_imports, use || : for legitimate empty-string fallbacks
- y-cluster-converge-ystack: use absolute paths in _resolve_target
