- Around line 98-99: Preflight both OCI chart artifacts before publishing either
one to prevent partial releases. In
.github/workflows/internal-chart-publish.yaml lines 98-99, extend the
existing-artifact check to include watchtower:${VERSION} before the operator

preflight for operator:${VERSION} and watchtower:${VERSION} before publishing.
In `@deploy/watchtower/templates/_helpers.tpl`:
- Around line 30-35: Update the serviceAccountName helper so that when
serviceAccount.create is false, it requires a non-empty serviceAccount.name and
fails template rendering instead of falling back to "default"; preserve the
existing generated fullname behavior when creation is enabled.
In `@deploy/watchtower/templates/secret.yaml`:
- Around line 1-2: Update the Secret template condition around auth.create to
also require auth.existingSecret to be empty, so an existing configured Secret
takes precedence and prevents rendering a generated Secret.
- Around line 10-27: Update the Secret template to use .Values.auth.secretKey
instead of the hardcoded "password" key when reading the existing Secret and
when writing stringData, while preserving the generated and reused password
behavior.
In `@deploy/watchtower/templates/service.yaml`:
- Around line 16-24: Update the service configuration defaults so the Watchtower
Service uses ClusterIP rather than NodePort, preventing direct plain-HTTP
exposure by default. Preserve explicit service-type overrides for deployments
that provide TLS through an Ingress or Gateway, and ensure nodePort is only
rendered for an explicitly selected NodePort service.
In `@deploy/watchtower/values.yaml`:
- Line 19: Remove the unused replicaCount setting from the chart values, since
the deployment template hardcodes spec.replicas to 1 and does not consume it.
- Around line 65-99: Change the default role type in the RBAC configuration from
ClusterRole to Role so the generated binding is namespace-scoped. Preserve
ClusterRole as an explicit opt-in for cross-namespace administration, without
changing the existing permission rules.
In `@docs/watchtower-deployment.md`:
- Around line 78-84: Update the Watchtower routing guidance to prohibit direct
public exposure of the plain-HTTP NodePort. Require TLS termination before
Watchtower, or explicitly limit NodePort use to a trusted private network, and
address the corresponding guidance in the referenced deployment section as well.
- Around line 55-63: Update the resource table in the deployment documentation
to reflect the chart’s role.type behavior: describe Role with RoleBinding for
namespaced mode and ClusterRole with ClusterRoleBinding for the default
cluster-wide mode, making the default scope explicit.
- Around line 89-96: Update the root-hosting instructions in “The base path is a
build-time value” to use the chart’s top-level basePath setting, documenting
basePath: "" or --set basePath="" instead of watchtower.basePath.
- Around line 130-137: Update the password retrieval example to reference the
Secret name watchtower-auth for the watchtower release, replacing the incorrect
wandb-watchtower-auth value while preserving the existing namespace, key, and
decoding command.
In `@docs/watchtower.md`:
- Line 229: Update the “Notes from Claude” heading in the documentation to use
level two, matching its parent “Open Questions/Notes” heading and avoiding a
skipped heading level.
- Around line 9-16: Add language identifiers to the fenced code blocks in the
Watchtower documentation flagged by MD040, using bash for the proxy
configuration, yaml for the ingress manifest, and text where the block is not
language-specific. Update all three affected fenced blocks while preserving
their contents.
- Around line 15-17: Restore the original line breaks and indentation in the
copied examples in the ingress, TypeScript, and AUTH_SERVICE snippets,
separating each YAML field, export declaration, and AUTH_SERVICE entry so all
examples are valid syntax.
- Around line 101-109: Update the “Packaging, Deployment and Routing” section to
accurately describe the shipped Dockerfile: use WATCHTOWER_IMAGE and
WATCHTOWER_VERSION, extract /watchtower, and copy it into the operator image.
Remove the inaccurate go.work/vendor build example and invalid Dockerfile
syntax, or clearly label it as a separate proposal for the Watchtower
repository.
- Around line 190-193: Update the release image configuration used by
docker-build so Dockerfile no longer resolves the unavailable Watchtower tag
0.11.0; set it to an existing compatible Watchtower image that serves
{basePath}/healthz and {basePath}/ready, preserving the configured base path.
In `@Makefile`:
- Around line 4-8: Define a single digest-backed WATCHTOWER_REF in the Makefile,
replace the independent WATCHTOWER_IMAGE and WATCHTOWER_VERSION defaults, and
pass WATCHTOWER_REF through every Docker build target, including docker-buildx.
In the Dockerfile, update the Watchtower image reference to consume
WATCHTOWER_REF via FROM so all builds use the pinned digest.
Apply the same fix in `@docs/watchtower.md` at line 60.

Require a ServiceAccount name when creation is disabled.
When serviceAccount.create=false and serviceAccount.name="", this helper returns default. The generated binding then grants Watchtower permissions to the namespace default ServiceAccount. Fail template rendering unless the user supplies a name.

Use auth.secretKey for generated and reused passwords.
When auth.secretKey is not password, the Deployment requests that key but this Secret only stores password. Kubernetes will not start the container because the requested key is absent. Use .Values.auth.secretKey in both the lookup and stringData.

Do not expose the default admin endpoint over plain HTTP.
The default NodePort Service publishes Watchtower directly, and this chart provides no TLS terminator. The cluster-mode admin password and session traffic can be captured by an actor on the network path. Default to ClusterIP and require a TLS-enabled Ingress or Gateway for external access.

Update the packaging section to match the shipped Dockerfile.
The supplied Dockerfile defines WATCHTOWER_IMAGE and WATCHTOWER_VERSION, extracts /watchtower, and copies it into the operator image. It does not copy go.work or build Watchtower from vendored source. The ENV GOWORK=offRUN ... example is also invalid Dockerfile syntax. Replace this section with the actual image-extraction flow, or mark it as a separate Watchtower-repository proposal.

sigs.k8s.io/controller-runtime default manager resync period
💡 Result:
In the sigs.k8s.io/controller-runtime library, the default resync period (SyncPeriod) is 10 hours [1][2][3]. This SyncPeriod determines the frequency at which watched resources are re-enqueued for reconciliation, even if no changes have been detected [1][2][3]. Importantly, a resync does not trigger a List request to the Kubernetes API server; instead, it re-emits existing objects from the local cache back through the event queue [3][4]. Key details regarding the SyncPeriod include: - Configuration: In recent versions, this can be configured via manager.Options.Cache.SyncPeriod [5]. - Jitter: To avoid performance spikes, a 10 percent jitter is automatically applied to the resync period across controllers to ensure they do not all perform resync actions simultaneously [2][6]. - Recommendation: The maintainers generally recommend against decreasing the default SyncPeriod [2][7]. If a controller needs to ensure regular processing (e.g., to handle external state changes or poll services that cannot be watched), it is recommended to have the Reconcile function return reconcile.Result{RequeueAfter: t} instead of changing the global SyncPeriod [2][6].

controller-runtime v0.22.4 default cache SyncPeriod manager Options requeue Result RequeueAfter
💡 Result:
In controller-runtime v0.22.4, the SyncPeriod and reconciliation requeue mechanisms serve different purposes in maintaining controller consistency [1][2]. SyncPeriod The SyncPeriod is a global cache-level setting that determines the frequency at which all watched resources in the cache are re-enqueued for reconciliation [1][3]. - Default: 10 hours [1][4]. - Purpose: It acts as a safety mechanism to ensure controllers eventually reconcile objects even if watch events are missed or if internal state diverges [1][5]. - Configuration: It is configured via manager Options, specifically under the cache options: manager.Options{Cache: cache.Options{SyncPeriod: &someDuration}} [6][3]. - Note: In v0.22.4, support for granular SyncPeriod configuration was added [7][8], allowing more flexibility than the previous monolithic setting. Reconcile Result (RequeueAfter) The Reconcile function's returned Result allows for per-object, conditional requeuing [9][2]. - RequeueAfter: If set to a non-zero duration, the controller will re-enqueue the object after that specific delay [9][3]. This bypasses the workqueue rate-limiter and is the recommended approach for polling external systems or re-checking conditions that are not triggered by watch events [1][9][3]. - Requeue (Deprecated): The Requeue boolean in Result is deprecated; RequeueAfter should be used instead [9]. Returning Requeue: true results in a rate-limited requeue, which is intended for error-handling, not as a replacement for scheduled polling [9][3]. Recommendation For the vast majority of use cases, the default SyncPeriod of 10 hours should be left unchanged, as lowering it can significantly increase API server load without providing real-time responsiveness [1][2][3]. Use RequeueAfter within your Reconcile loop when you need to schedule a specific object for later processing [1][2].

Requeue when reconcileWatchtower fails.
If the remaining reconciliation succeeds, the logged Watchtower error produces no RequeueAfter. Existing Application and Secret watch events do not cover failures before those resources exist, and the default cache resync is 10 hours. Preserve the error and merge defaultRequeueDuration into the final result, using the shorter non-zero delay. Add a Ginkgo/Gomega test for this path.

270-273: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winWatchtower reconciliation failures still have no explicit requeue path.
ReconcileNetworkingAndWatchtowerreturns onlyerror. Per its description, it treats networking failures as fatal but logs Watchtower failures without aborting. When it swallows a Watchtower failure, it returnsnilhere, andReconcileproceeds toconsolidateResults(ctrlResults)with noRequeueAftercontributed for that failure. The object then only gets re-reconciled on an unrelated trigger or the default 10-hour cache resync, until the Watchtower resources converge on their own.Track the Watchtower error inside
ReconcileNetworkingAndWatchtower, and either return it as a fatal error or folddefaultRequeueDurationinto the returned result (merging viaconsolidateResults, choosing the shorter non-zero delay). Add a Ginkgo/Gomega test that exercises a Watchtower failure alongside an otherwise successful reconciliation.This restates a previously raised Major issue on the predecessor of this function; the reported behavior indicates it remains unresolved after the refactor.
