The barynt command

The installer puts itself on your server as barynt. It runs your upgrades, backups and checks.

Commands

Command	What it does
`barynt status`	Containers, version and health
`barynt upgrade`	The newest version (or `--version`), with a backup first
`barynt backup`	Database, uploaded files and `.env` in one archive
`barynt restore <archive>`	Replace the data with a backup
`barynt logs [service]`	Follow the logs of app, postgres, caddy …
`barynt config [K=V …]`	Change the domain or SMTP; interactive without arguments
`barynt doctor`	Checks Docker, memory, disk, DNS and health
`barynt start \| stop \| restart`	What it says
`barynt uninstall`	Removes the containers; `--purge` also deletes all data

Upgrading

barynt upgrade                   # backup, then the newest release
barynt upgrade --version 1.0.12  # a specific one

The app applies database migrations itself when it starts. Use --no-backup to skip the backup and --force to reinstall the same version or go back to an older one.

Backups

barynt backup --output /mnt/backups
barynt restore /mnt/backups/barynt-1.0.12-20261028-0300.tar.gz
