A fabric file to bootstrap an Ubuntu system for use as a VirtualBox master image for development VMs using port-forwarding and shared folders.

"""A fabfile to boostrap a vanilla VirtualBox master image
Generally you will create a master image with the following commands::

fab -f ./bootstrap_venv_fab.py -H 'localhost:2222' -u somedev -p somedev shared

A script to bootstrap a new Ubuntu machine for use as a PHP webserver. This gist exists to remind me / demonstrate a handful of techniques for organizing a large shell script.

whiteinge / postconfig-vbox.sh
Created April 30, 2013 21:17
Shell functions for doing post-OS-install configuration of a VirtualBox VM. In particular, a shell wrapper around ``VBoxManage guestcontrol`` that allows running commands on the guest without knowing the IP or having ssh configured. Also includes an example of pushing small files (through stdout) to the guest via HEREDOC.
#!/usr/bin/env bash
# Post-configure a newly imported development VM.
NAME=$(basename $0)
# These vars may be overridden by envionment variables of the same name but
# with a preceeding "DEV_"
USER=${DEV_USER:-"somedev"}
PASS=${DEV_PASS:-"somedev"}
VM=${DEV_VM:-"localdev"}

Salt is used to execute functions across a wide variety of locations in a wide variety of ways. It does this by mapping the function name and function parameters within a data structure (JSON-serializable). Unfortunately, there is a variety of formats in different parts of Salt for doing so.
