Ben's VirtualEnv Cheatsheet

This cheat sheet describes my usage/implementation of virtualenv with virtualenv wrapper and the bash foo that I added with the help of many blogs to make it all tick together in fun land.

Quick Reference

$ echo $WORKON_HOME
/Users/benjamin/.virtualenvs

$ echo $PROJECT_HOME

Typing vagrant from the command line will display a list of all available commands.

Be sure that you are in the same directory as the Vagrantfile when running these commands!

Creating a VM

vagrant init -- Initialize Vagrant with a Vagrantfile and ./.vagrant directory, using no specified base image. Before you can do vagrant up, you'll need to specify a base image in the Vagrantfile.
vagrant init <boxpath> -- Initialize Vagrant with a specific box. To find a box, go to the public Vagrant box catalog. When you find one you like, just replace it's name with boxpath. For example, vagrant init ubuntu/trusty64.

Starting a VM

vagrant up -- starts vagrant environment (also provisions only on the FIRST vagrant up)

	git rebase --interactive HEAD~2

	pick b76d157 b

	# Starts an EC2 instance _if needed_ and runs an SSH command or opens a shell.

	# Summary of steps:
	# 1. Checks current instance status
	# 2. Starts instance if needed
	# 3. Waits for the instance to be ready (status "running")
	# 4. Connects via SSH, possibly running a command
