What dokku/dokku shipped

Week of September 14, 2026

What shipped

• Release v0.38.28 with bug fixes for build records, build output, and git sync. Release
• Global flags like --quiet, --trace, --force and --app now work correctly with sudo-rs on Ubuntu 25.10 and later. Pull request #9060
• Storage plugin now supports whole-set form for mounting, allowing you to declare and sync an app's complete set of mounts in one command. Pull request #9058
• Scheduler-k3s metadata commands now support whole-set form for annotations, labels and node sysctls. Pull request #9051
• dokku run under k3s scheduler now exits with the command's own exit status instead of always exiting 1 on failure. Pull request #9011
• Config commands now report write failures instead of silently exiting 0 when writes fail. Pull request #9049
• Process scaling now rejects negative process counts immediately instead of storing them for the scheduler to reject later. Pull request #9050
• Bootstrap installer now supports Ubuntu 26.04 LTS. Pull request #8791
• Storage mounts now check scheduler compatibility at mount time to prevent mismatched docker-local and k3s resources. Pull request #9010
• Registry plugin now exposes login state so you can check whether Dokku is logged in to a registry. Pull request #9057

Why it matters

This release focuses on fixing silent failures and improving reliability across multiple subsystems. Better error reporting in config operations, process scaling, and build output means issues surface immediately rather than causing cryptic failures downstream. Whole-set forms for storage and scheduler metadata reduce operational complexity when declaring infrastructure as code.
