It is Python Exercise for an assignment challenge, the aim is manage debian nodes using Paramiko implementation of the SSHv2 protocol not utilising our of shelf tools as ansible, puppet, etc. This is limited to manage packages, move files to the server, restart web server.

It was implemented and tested using Python 3.7.2:

This should be executed in an environment (virtualenv) using the requirements.txt file

run:

$ python appdeploy.py -f production/production.yaml -a setup
$ python appdeploy.py -f production/production.yaml -a deploy
$ python appdeploy.py -f production/production.yaml -a restart

/slack : source code /production : environment descriptor and files slackdeploy.py : main file

usage: slackdeploy.py [-h] -a {setup,deploy,start,stop,restart,update,uname} -f FILE [-d]

• a: defines an Action

  • setup: Install and Uninstall debian packages listed in descriptor file
  • deploy: Upload files listed in descriptor file
  • update: update all packages (apt-get update)
  • uname: performs uname command on nodes
  • restart: restart the web server accordingly with defined on descriptor file

• f: Yaml descriptor file path

• d: Debug loggin

The descriptor file is a yaml file where nodes, credentials, files and webserver are defined. You can find in this file:

Hosts: list of hosts defining address, user and password

Dependencies: Defines the deb packages, it has 2 sub items, Install and Uninstall, this gonna perform apt-get install and apt-get remove respectively.

Files: What files should be uploaded, remote path, permissions, user and group.
