file-sync-tool-kmi 0.4.8

Synchronize files from and to host systems.

file sync tool

Python script to synchronize files from an origin to a target system using rsync.

This tool is an addon of the db-sync-tool.

Installation

Prerequisite

The script needs python 3.5 or higher. It is necessary for some additional functionalities to have pip installed on your local machine.

pip

The library can be installed from PyPI:

$ pip3 install file-sync-tool-kmi

composer

The script is also available via packagist.org using composer:

$ composer require kmi/file-sync-tool

Additionally install the python requirements via the following pip command:

$ pip3 install -e vendor/kmi/file-sync-tool/

Configuration

You can configure the script with shell arguments or using a separate configuration file.

Configuration File

The config.json contains important information about the origin and the target system.

Example structure of config.json in receiver mode :

{
  "target": {},
  "origin": {
    "host": "ssh_host",
    "user": "ssh_user"
  },
  "files": {
    "config": [
      {
        "origin": "/var/www/html/files/",
        "target": "/var/www/html/files/",
        "exclude": [
          "*.log"
        ]
      }
    ]
  }
}

Documentation

Extend the config.json with a files section containing multiple transfer entries within the configentry. Therefore you have to specify the origin source path as well as the target destination path of the file sync. Additionally define the rsync excludes for this specific transfer.

In the config entry you can also define additional rsync options as a list overwriting the default options.

For further information see the documentation of the db-sync-tool.
