Cron containers were never reaped once they exceeded their active deadline, so a hung cron task ran indefinitely instead of being retired after 24 hours as documented. `cron:run` now also accepts a `--ttl-seconds` argument, matching the one `dokku run` already takes.
Kubernetes pulls the app image itself, so a k3s host is free to reap its local copy while the workload keeps running, which the `registry` plugin already does on its own. Deploys, restarts, `dokku run`, and in-cluster cron no longer assert that the image is present locally, falling back to the metadata recorded in the app's current Helm release. A `ps:restart` naming a single process type now rolls only that process type's pods rather than silently redeploying every one. Apps with an `app.json` postdeploy task still require the image locally, as that task runs on the Dokku host.
Traefik matches hosts exactly, so an app serving a wildcard domain under the `traefik` ingress class had a valid certificate but silently 404d on every request. Wildcard domains now render as a `HostRegexp` rule that matches a single label, the same semantics as a Kubernetes wildcard host, so both ingress classes behave the same. Those routes carry an explicit low priority so an exact domain on any app still wins over another app's wildcard, mirroring ingress-nginx.
The `docker-local` scheduler supports `--sysctl` for free because docker options are passed verbatim to `docker run`, but the k3s scheduler silently dropped it. Namespaced sysctls now render into the pod's `securityContext.sysctls` for deployments, cron jobs, and one-off runs. A sysctl the kernel does not namespace fails the deploy instead of being dropped, since it cannot take effect within a pod regardless of what was requested.
The `issuer.yaml` chart template dereferenced `.Values.global.issuer.enabled` without guarding against the value being absent, which yaml serialization omitted for apps without a per-app email, causing a nil-pointer render error that broke every k3s web deploy.
The `letsencrypt-email-prod` and `letsencrypt-email-stag` properties can now be set per app in addition to globally, resolving app-level before the global value for the app's selected `letsencrypt-server`. An app that sets its own email renders a namespaced cert-manager `Issuer` using that email, while apps without an override continue to use the shared `ClusterIssuer` with the global email.
The `dokku.com/cron-id` label could exceed Kubernetes' 63-byte cap because the cron ID is `base36(appName === command === schedule)`, which expands roughly 1.5x per byte. The label is now keyed `dokku.com/cron-hash` and holds the `sha1` hex digest of the cron-id, a fixed 40-character value that always fits the cap. The same hex digest is mirrored into the `dokku.com/cron-hash` annotation, and the original base36 cron-id stays in the `dokku.com/cron-id` annotation that `cron:list` reads when surfacing user-facing IDs. Per-task lookups stay server-side via label selectors, so `cron:set --maintenance` and the forbid/replace concurrency checks on `dokku run --cron-id` keep working without any in-memory filtering.
The cron-id label could exceed Kubernetes' 63-byte cap when commands or
schedules were long, and an all-digit job-suffix or cron-id rendered as
an unquoted YAML scalar caused the API server to reject manifests. Run
pods built from dockerfiles also occasionally hit the 10s startup wait
on a cold image pull, even though the pod was scheduled correctly.
The cron-id is now stored as an annotation and a shorter hash is used as
the selector label. Every interpolated annotation and label value in the
cron-job and deployment templates is now quoted to prevent numeric
coercion, and the run-pod wait timeout is raised to 30 seconds.
Mirror the docker-local fix in #8525 for the k3s scheduler. CNB images default to a `/cnb/process/web` entrypoint that ignores incoming args, so non-web deployments, scheduled cron jobs, and ad-hoc `dokku run` / `cron:run` commands all need an explicit `launcher` entrypoint. The deployment and cron-job helm templates now set `command: [launcher]` when `image.type` is `pack`, and `TriggerSchedulerRun` sets the entrypoint to `launcher` for pack images while finishing the previously stubbed Procfile lookup branch so the resolved command is actually scheduled.
Adds a per-entry storage helm chart that owns the PVC and (when host_path is set) the PV, and three triggers for the storage plugin to drive: storage-create installs/upgrades the chart with storage-class existence validation, storage-destroy uninstalls it, storage-status reports the PVC phase. App deployment and cron-job charts now consume storage-app-mounts and reference each PVC by name; the // todo: implement volumes blocks are gone. ProcessVolume gained sub_path, read_only, and persistent_claim fields and the deployment/cron-job templates render them.
Bundling these Secrets in the app helm chart caused two bugs in the scheduler-k3s plugin: a chart rollback could delete Secrets that older ReplicaSets still referenced by exact timestamped name (`env-{app}.{ts}` and `ims-{app}.{ts}`), hard-crashing pods until manual intervention; and the strategic-merge `patchMergeKey` on `imagePullSecrets` let stale entries leak into the live Deployment until the list pointed at many nonexistent Secrets. Each Secret now lives in its own helm release with a stable name (`config-{app}` and `pull-secret-{app}`), installed before the app chart on every deploy. The deployment trigger also prunes any leaked `imagePullSecrets` entries from the live Deployment so the next deploy lands on a clean list, and the rename and destroy paths uninstall the new releases (and the previously-leaked TLS release on rename) under the old app name.
Keda 2.17+ rejects ScaledObjects whose spec.fallback is set unless at least one trigger is not a cpu or memory scaler, so unconditionally emitting fallback broke deploys for apps autoscaled on cpu or memory alone. The chart now skips the fallback block when every configured trigger is cpu or memory and keeps the existing behavior otherwise.
If the values set by keda do not match the current deployment replicas value, the deployment object may be scaled in unexpected ways during a helm release. This change ensures keda will continue to manage that value correctly without the deployment object setting it back to something else.
Domains cannot be reused across ingress objects, and port maps are a function of a domain, so the inversion here makes most sense (at the cost of some downtime when migrating.
