sshmirror 0.1.6

SSH directory synchronization library and CLI

SSHMirror

Sync a working directory with a remote server over SSH, inspect diffs before applying changes, and keep a lightweight local history for rollback-oriented workflows.

SSHMirror is both:

• a Python library you can import;
• a CLI you can run inside a project folder;
• a sync workflow that keeps local and remote changes inspectable.

It can also be used as a lightweight sync workflow for a shared project: multiple developers can make changes to the same remote-backed codebase and inspect differences before pulling or pushing updates.

Internet access is not required for SSHMirror itself. It only needs network access to the target SSH host or Docker host you are synchronizing with.

When you run sshmirror without arguments, it opens an interactive menu. Depending on project state, the menu can include:

• Create sshmirror.config.yml
• Create sshmirror.ignore.txt
• Initialization
• Pull & Push
• Status
• View current changes
• View version changes
• Pull only
• Stash changes
• Restore stashed changes
• Force pull
• Discard all local changes
• Discard selected files
• Downgrade remote version
• Test connection
• Exit

Why It Stands Out

• Preview first. Inspect current file changes and version-to-version diffs before syncing. 🔍
• Built for real SSH workflows. Passwords, SSH keys, passphrases, and ssh-agent fallback are supported. 🔐
• Keeps local state. SSHMirror stores version and migration metadata under .sshmirror/. 🗂️
• Works as a library or a command-line tool. 🐍
• Useful for team workflows. Several developers can work on one project and sync changes through the same remote environment. 🤝
• Optional remote container restart after sync. 🐳

Install 🚀

pip install sshmirror

For local development:

pip install -e .

Quick Start ⚡

1. Create a config file:

   sshmirror
   

   On first interactive launch, SSHMirror can create sshmirror.config.yml for you.

2. Start from this minimal config:

   host: '192.168.12.22'
   port: '50022'
   username: 'root'
   localdir: '.'
   remotedir: '/app'
   author: your-name
   

3. Check status or connect-test before syncing:

   sshmirror --status
   sshmirror --test-connection
   

Example Configuration ⚙️

The full example lives in sshmirror.config.example.yml.

Supported auth patterns:

• password auth;
• private key auth;
• private key with passphrase;
• default SSH keys or ssh-agent when no key and no password are provided.

Example with optional container restart:

host: '192.168.12.22'
port: '50022'
username: 'root'
localdir: '.'
remotedir: '/app'
author: your-name

restart_container:
   # Optional. If omitted, host/port/user are reused from the main SSH config.
   # host: '192.168.12.22'
   # port: '23322'
   # user: user
  sudo: true
  container_name: testcontainer

restart_container connects to the Docker host where the container is running. If host, port, or user are not specified there, SSHMirror uses the main connection values.

CLI Commands 🧰

sshmirror --help

Main non-interactive flags:

• --status show local and remote sync status;
• --current-diff inspect current local versus remote differences;
• --version-diff inspect changes between remote versions;
• --pull only pull from remote;
• --stash-changes stash local changes before syncing;
• --restore-stash restore previously stashed changes;
• --force-pull overwrite local files from remote;
• --discard discard all local changes;
• --discard-files <paths...> discard only selected files;
• --downgrade downgrade remote version;
• --test-connection validate SSH access to the remote host and configured Docker host.

Library Usage 📦

from sshmirror import SSHMirror, SSHMirrorConfig

mirror = SSHMirror(
    config=SSHMirrorConfig(
        host='127.0.0.1',
        port=22,
        username='root',
        localdir='.',
        remotedir='/app',
    )
)

The public API is exported from sshmirror/init.py.

Project Layout

sshmirror/
  sshmirror/          # importable package

Development 🛠️

Run tests:

python -m unittest discover -s tests -p "test_*.py"

Build locally:

python -m build

Status

This repository is structured as a Python package with a CLI entry point. If you plan to publish to PyPI, keep package metadata, README, and license in sync with actual behavior.
