`common.GetDeployingAppImageName` runs `VerifyImage` and errors out when
no image has been built for the app. A freshly-created app has no image
yet, so the preview could never render for never-deployed apps. Add an
`AllowMissingImage` flag to `BuildOptions` that lets BuildAppChart
substitute a placeholder image string in that case; CommandPreview sets
it. The deploy path still passes `BuildOptions{}`, so missing-image
remains a hard error there.
Without this, the preview build invented a fresh timestamp for
`Values.global.deployment_id` and the resulting diff showed every
Deployment changing its `app.kubernetes.io/version` annotation - even when
nothing semantically changed. CommandPreview now reads the deployment id
out of `release.Chart.Metadata.Version` and passes it through a new
`BuildOptions.OverrideDeploymentID` parameter so the previewed manifests
carry the same version label as the live release. The deploy path still
generates a fresh timestamp.
The previous commit added the dispatcher case but missed appending
`subcommands/preview` to the plugin's `SUBCOMMANDS` list, so no symlink
was created at install time and dokku reported the command as unknown.
Users can override the default 3-line surrounding context per change. Pass
`--context -1` to render the full resource around every change, matching
upstream `helm diff upgrade` behavior.
Adds a `scheduler-k3s:preview <app>` command that renders a unified diff
between the manifests currently stored in the live Helm release for an app
and the manifests that the next deploy would roll out. The diff is produced
entirely via the Helm Go SDK that scheduler-k3s already uses, with no
external `helm` binary or `helm-diff` plugin install required. The
underlying diff and parse logic is vendored from `databus23/helm-diff`
(Apache 2.0) into a new internal package, trimmed of three-way-merge,
release-ownership tracking, and the non-default output formatters.
The chart-construction half of `TriggerSchedulerDeploy` has been extracted
into a reusable `BuildAppChart` helper so deploy and preview share the
same chart materialization without duplicating template logic. Secret
values are redacted by default in preview output; `--show-secrets` and
`--show-secrets-decoded` flags match the upstream `helm diff` UX. Only the
main app helm release is compared in this iteration; auxiliary releases
for config vars, image-pull secrets, and TLS certificates are out of scope
and documented as such.
Kubernetes 1.20 deprecated the node-role.kubernetes.io/master label and replaced it with node-role.kubernetes.io/control-plane, and 1.24 dropped the legacy label entirely. The scheduler-k3s:cluster:add join path still filtered control-plane nodes with master=true, so on any k3s release built from Kubernetes 1.24+ the lookup matched zero nodes and aborted with "no nodes found in the cluster" before the worker could join.
Annotation and label values containing a newline previously round-tripped
as two adjacent `key: value` lines, and the second line then failed the
`SplitN(line, ": ", 2)` parse on read. Move the per-`(processType,
resourceType)` files to `PropertyMap*` storage so `\n` in values and `/`
in keys are preserved verbatim. An idempotent `TriggerInstall` migration
walks `--global` and every app, converting any legacy line-formatted file
in place by probing `PropertyMapGet` first and rewriting via
`PropertyListGet` only when the probe fails. Property names are
unchanged, so the annotations/labels report scanner and the
`reservedAnnotationPrefixes` filter keep working without modification.
Closes#8719.
PropertyMap tests went through SetPermissions, which looks up the `dokku` user/group; the fresh `golang:1.26.2` container used by `go-test-plugin-in-docker` has neither, so the chown failed with `unknown group dokku`. Override `DOKKU_SYSTEM_USER` and `DOKKU_SYSTEM_GROUP` to `root` in the property and chart-migration test setups so the chown targets an identity that exists everywhere. The config tests also called `plugn trigger post-config-update` without `PLUGIN_CORE_AVAILABLE_PATH` set, so the hook tried to source `/common/functions` and logged a noisy warning on every test; point the env var at the canonical `/var/lib/dokku/core-plugins/available` location.
Chart property names containing `/` failed because per-key flat-file storage interpreted the slash as a filesystem path separator, and any move to line-based storage would silently truncate multi-line values. A new `PropertyMap*` helper family in `common` persists each map as a single JSON file so both `/` in keys and `\n` in values round-trip losslessly. Chart overrides move to `chart-overrides.<chart>` and an idempotent `TriggerInstall` migration rewrites any legacy `chart.<chart>.<key>` files into the new layout. The deprecated `scheduler-k3s:set --global chart.*` form is rerouted through the same map storage so it does not silently orphan writes. Closes#8717.
The scheduler-k3s plugin exposes `annotations:set` and `labels:set` but no matching report subcommands, so scripts could not inspect the configured state for idempotent management without reading the property files directly. The new `scheduler-k3s:annotations:report` and `scheduler-k3s:labels:report` surface the configured entries with stdout, JSON, single-flag query, and `--process-type` / `--resource-type` filtering, mirroring the recently added `scheduler-k3s:charts:report`. The literal `GlobalProcessType` value `--global` is rendered as `global` in report keys to avoid leading dashes. The `scheduler-k3s:autoscaling-auth:report` command is updated alongside to loop over every app when no app and no `--global` flag is provided, matching the convention used by `scheduler-k3s:report`.
Helm chart overrides on the scheduler-k3s plugin were previously set
through the generic `scheduler-k3s:set --global chart.<chart>.<property>`
interface, which mixed chart-level configuration into the same command
that manages scheduler properties and offered no focused way to inspect
which overrides were configured. A dedicated `scheduler-k3s:charts:set`
sets and clears chart-specific helm values, and a complementary
`scheduler-k3s:charts:report` surfaces configured overrides per chart
with optional JSON output and single-field flag queries. The legacy form
on `scheduler-k3s:set` continues to work but now emits a deprecation
warning pointing users at the new subcommand.

## 0.38.10

### New Features
- #8702: @josegonzalez Prompt for confirmation on storage:destroy
### Tests
- #8698: @dependabot[bot] chore(deps-dev): bump org.apache.maven.plugins:maven-dependency-plugin from 3.10.0 to 3.11.0 in /tests/apps/java
Every Go-implemented plugin's `:report --format json` now emits keys without the redundant `<plugin>-` head segment, matching the shape bash plugins have always emitted. The CLI flag names and `:set` semantics are unchanged. For backwards compatibility during the 0.38.x patch series, the legacy `<plugin>-<property>` keys are emitted side-by-side with the new keys, and a future major release will drop the legacy keys. `common.ReportSingleApp` is refactored to accept a `ReportSingleAppInput` struct with a `Validate()` method so the input is checked before any work runs, which also catches the latent `"docker options"` reportType bug at the API boundary.
Adds the missing raw/global/computed report keys for ten settable properties across the ps, builder, scheduler, proxy, openresty, nginx, and scheduler-k3s plugins so external tooling can verify drift through `:report --format json`. The scheduler-k3s `token` is masked as `*******` in default stdout output and only unmasked when the report is requested via `--format json` or when the flag is queried explicitly by name; the same explicit-query unmasking rule is extended to the existing traefik `dns-provider-<env_var>` keys.

### Other
- #8680: @josegonzalez Split more report global keys into raw and computed
Three plugins still leaked the built-in default through `<plugin>-global-<property>` after the broader raw/computed split in #8640. External tooling reading `:report --format json` for drift detection could not distinguish "set to default" from "never set" - after a `:set --global` followed by an unset, the JSON still reported the default value. The `<plugin>-global-<property>` keys now hold the raw stored value (empty when nothing has been set) and `<plugin>-computed-<property>` keys hold the effective value with per-app, global, and built-in default fallback. Every global property now has a computed sibling for shape consistency, including those whose default is empty. Internal callers in `scheduler-k3s` that previously read the default-applied global helpers now consume new `getComputed*` helpers, keeping deploy-time behavior unchanged.

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.
Adds four Go template tests for ingress-route.yaml covering the imported-cert secret name, multiple domains per IngressRoute, the non-traefik ingress_class guard, and the https port_map dedup when an http port_map already covers the same container port. Also adds a bats integration test that deploys a TLS-enabled app under traefik and asserts both IngressRoute manifests and live http-to-https redirect plus https serving.
