Syntax
Commands
Command Reference
add
Add a new Lagerbox configuration.
Options:
--name (required) - Name to assign to the box
--ip (required) - IP address of the box
--user (required) - SSH username for the box (the account you log in as)
--version - Lager Box version/branch (e.g., staging, main)
--yes - Confirm without prompting
--user is required. It previously defaulted to lagerdata, but
since most boxes use a different login account, the default was removed so the
correct user is always recorded for SSH, updates, and lager ssh.
Examples:
add-all
Automatically add all Lagerboxes found on your Tailscale network.
Options:
--yes - Confirm without prompting
This command scans your Tailscale network for devices with names 5-8 characters long (typical Lagerbox naming convention) and automatically adds them as boxes with uppercase names.
How it works:
- Runs
tailscale status to discover devices
- Filters for devices with names 5-8 characters long
- Converts names to uppercase
- Skips boxes that already exist with the same IP
- Adds new boxes to your configuration
Example:
delete
Delete a box configuration.
Examples:
edit
Edit an existing box configuration.
Options:
--name (required) - Name of the box to edit
--ip - New IP address
--user - New SSH username
--version - New Lager Box version/branch
--new-name - Rename the box
--yes - Confirm without prompting
Examples:
list
List all configured boxes with live version status. This is also the default behavior when running lager boxes with no subcommand.
The command queries each box’s /cli-version endpoint to display real-time version and status information.
Output:
Status Colors:
delete-all
Delete all box configurations.
export
Export box configuration to JSON file.
Options:
--output / -o - Output file path (prints to stdout if not specified)
Examples:
import
Import box configuration from JSON file.
Options:
FILE - Path to JSON file to import
--merge - Merge with existing boxes (default: replace)
--yes - Confirm without prompting
Examples:
lock
Lock a box to prevent other users from using it. See Box Locking for full details.
Options:

Example:
unlock
Unlock a box to allow other users to use it. See Box Locking for full details.
Options:
--box (required) - Name of the box to unlock
--force - Force unlock even if locked by another user
Examples:
Configuration Storage
Box configurations are stored in .lager file in your project directory:
Entries can be:
- Simple: Just an IP address string
- Full: Object with ip, user, and version fields
Validation
The boxes commands perform validation:
- Duplicate detection: Prevents adding boxes with same name or IP
- IP validation: Validates IP address format
- Confirmation: Shows before/after state for edit operations
Examples
Notes
- Box names must be unique
- IP addresses must be unique (no duplicate IPs)
--user is required when adding a box (there is no default SSH user)
- Use
--merge when importing to preserve existing boxes
- Sync command requires Lager Boxes to be online and accessible
