flashback is a python script that leverages fabric to quickly roll-back configuration changes gone awry. Thanks to fabric, it parallelizes well, and provides quick recovery for replacing smallish text files with previous versions, assuming sshd continues to work and the authenticated user on the remote server has appropriate sudo permissions.
For the full CLI reference including usage examples, please see full project documentation.
To get up and running, the following must be installed:
- python 2.7.x
- fabric and its dependencies
- jinja2
- Create a virtual environment and activate
- Clone this git repository
- pip install .
Optionally for sphinx document generation, pip install the following
- sphinx
- pygments
- sphinx_rtd_theme
- sphinx-argparse
