DSMT

Docker Storage Migration Tool (DSMT) is a command-line utility for seamlessly exporting and importing Docker volumes and bind mounts.

Overview

DSMT provides a simple way to:

• Export Docker volumes or bind mounts to compressed tarballs.
• Import compressed tarballs into Docker volumes or bind mounts.

This tool makes it easy to backup, restore, or migrate Docker storage across systems.

Installation

Global Installation

Choose your preferred package manager to install the CLI globally:

# npm
npm install -g dsmt

# yarn
yarn global add dsmt

# pnpm
pnpm add -g dsmt

# bun
bun add -g dsmt

Run Directly

Or run directly without manual installation using:

# npx (npm)
npx dsmt <command> [args]

# bunx (bun)
bunx dsmt <command> [args]

# pnpm dlx
pnpm dlx dsmt <command> [args]

# yarn dlx
yarn dlx dsmt <command> [args]

Usage

Exporting Docker Storage

Export a Docker volume:

dsmt export volume_name /path/to/export/directory

Export a bind mount:

dsmt export /path/to/bind/mount /path/to/export/directory

Importing Docker Storage

Import to a Docker volume:

dsmt import /path/to/tarball.tar.gz volume_name

Import to a bind mount:

dsmt import /path/to/tarball.tar.gz /path/to/bind/mount

Options

Both commands support the following options:

• -v, --volume: Explicitly specify source/destination as a Docker volume
• -b, --bind: Explicitly specify source/destination as a bind mount

The tool will automatically detect the source/destination type in most cases, but you can use these flags to be explicit.

Examples

# Export a volume named 'mongodb_data' to the current directory
dsmt export mongodb_data ./

# Import a tarball to a new volume
dsmt import ./mongodb_data.tar.gz new_mongodb_data

# Export a bind mount to the /backups directory
dsmt export /var/www/html /backups

# Import a tarball to a bind mount
dsmt import ./html.tar.gz /var/www/html
