DevOpsiPy Project

Abstract

Project aims to create generic, DevOps oriented framework in Python 3

Usage

Copy module to your project directory:

git clone git@github.com:kharnam/devopsipy.git

In your modules:
logger.py
main.py module:

from devopsipy import logger

log = logger.set_logger('MyCoolProject')
log.info('The first message from MyCoolProject Main module')

test.py module:

# Close to module top
import logging
log = logging.getLogger(__name__)
log.info('Logging from MyCoolProject Test module')

_host_base.py_

from devopsipy.host_base import HostBase

l_host = HostBase('localhost')
r_host = HostBase('my_remote_machine.example.com', ssh_user='user', ssh_key_file='~/.ssh/id_rsa')

l_host.run('uptime', print_pstate=True)
r_host.run(['mkdir test', 'cd test', 'ls -l'], print_stdout=True)

Current functionality

logger.py

Fully functional pre-configured logging facility

• 3 logger formatters:

  • default
  • detailed
  • silent

• 4 logger handlers:

  • console -- colorized stream handler
  • info_file_handler -- level INFO, separate log file with rotation
  • error_file_handler -- level ERROR, separate log file with rotation
  • debug_file_handler -- level DEBUG, separate log file with rotation

• Creates separate folder under '/tmp/logs' on every init and creates symlinks to the latest log files
