Python Setuptools (Packaging Guidelines) #python

Python Setuptools

Python setuptools package replaces the distutils package. You use this in order to allow your Python package to be redistributable. Not just for PyPi but also for source distributions or private distributions.

First you need a setup.py at your project root:

Opening and closing an SSH tunnel in a shell script the smart way


I recently had the following problem:


    

  • From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
    • 

  • That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.
    • 



We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like


ssh -L 3306:localhost:3306 remotehost
