Summary

  • Uploaded branding assets (app icon / logo / privacy screen) were written to /app/resources/public/upload inside the container writable layer, not on a volume. A image rebuild/recompose destroyed them, leaving 3 dead /upload/.../ URLs referenced by a saved preset and builds fix(custom-client): clearer delete confirm, surface failure, harden T() #39/fix(i18n+custom-client): drop double-toast on delete, fix T() falsy-param substitution #40. Diagnosis verified against the live container.
  • Fix: mount ../data/uploads onto /app/resources/public/upload in docker/docker-compose.yml, so uploads survive rebuilds. Only resources-path/public writer is the admin upload handler (api/http/controller/admin/file.go), served back at GET /upload/ (api/http/router/api.go).
  • Admin UI: previews of unfetchable branding images now render an explicit "File unavailable" warning chip with a details tooltip instead of the neutral placeholder, so builds whose image URL is dangling can be spotted before a build is dispatched. This is a display state, not a validation change.

Why

DeskForge #80 documents how silently-failed previews produced clients with broken image URLs. The PR does not reopen issue #80; it is related context only.

Validation

  • Rebased onto origin/main (bf1506c); rebase applied cleanly with both sides' content preserved (no textual conflicts).
  • GOWORK=off go vet ./... — clean
  • GOWORK=off go test -count=1 ./service — ok
  • admin-ui node --test tests/custom-client-validation.test.mjs — 66/66 pass (main's parallel admin-ui commits grew the suite from the previously expected 62; all pass)
  • admin-ui npm run build — succeeds (pre-existing chunk-size warning only)

The live stack (host-side compose) already runs the same volume mount; a round-trip probe verified container/host/shared visibility plus GET /upload/ returning 200.

Summary by CodeRabbit

  • New Features
    • Branding image fields now show a warning when an image cannot be loaded, with details available in the preview.
    • The branding page displays a warning when the public API address is not configured.
  • Documentation
    • Image guidance now distinguishes upload and URL size limits, and clarifies format and dimension requirements for icons, logos, and privacy screens.
    • Updated guidance and unavailable-image messages are available in English, Russian, and Chinese.

mount ../data/uploads onto /app/resources/public/upload; only writer under resources-path/public is the admin upload handler file.go, served at GET /upload/ router/api.go; writable-layer placement was destroyed by recompose leaving dangling /upload URLs in presets/builds 39/40.
previewFailed now renders an explicit warning chip 'File unavailable' + details tooltip instead of the neutral placeholder, so dead /upload references are visible before a build is dispatched; non-validation state.

📝 Walkthrough

The branding UI now distinguishes failed image previews from empty previews and warns when the configured public API address is missing. Updated translations describe image source limits and availability. Docker Compose mounts persistent storage for uploaded public assets.

Changes: Branding image handling

Layer / File(s) Summary
Unavailable image preview
admin-ui/src/components/ui/ImageAttachField.vue
The image field accepts unavailable-image labels and details. It computes the preview’s accessible label and displays a focusable warning state when an image fails to load.
Branding configuration and uploaded assets
admin-ui/src/views/custom-client/index.vue, admin-ui/src/utils/i18n/*.json, docker/docker-compose.yml
The branding page warns when configuration lacks a public API address and passes unavailable-image messages to its image fields. Translations describe image limits and availability. Docker Compose mounts persistent storage for uploaded assets.

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 19715

Upgrading an existing deployment can make previously uploaded branding images unavailable because the new mount masks the container-stored files. Preserve those files before enabling the mount.

Single text system — field note carries format + file/link limits; upload button without size; hovers carry only the accepted-range details; section mechanics and unavailable details shortened; approved wording, en/ru/zh_CN parity.
Show one non-blocking warning banner in the branding-images section when /config/all reports public_api_server empty: /upload/... values cannot resolve to a public link and uploaded images will not reach builds. The env var to set is RUSTDESK_API_RUSTDESK_PUBLIC_API_SERVER.

- Around line 97-100: Update previewAriaLabel in ImageAttachField to check the
local previewFailed ref’s value instead of props.previewFailed, and declare
previewFailed before the computed getter so a failed preview returns
props.unavailableLabel.

Review comments at @docker/docker-compose.yml:
- Around line 48-52: Add an upgrade note to the deployment documentation
explaining that existing uploads must be copied from the old container’s
/app/resources/public/upload directory into ../data/uploads before applying the
bind mount, then recreate the service. Keep this scoped to documenting the
migration needed for the upload mount in the Compose configuration.
