# First, let's define some secrets we want to pass to Chef

cat << SECRETS > /etc/chef.secrets
DB_PASSWORD: !var db/postgres/customers/password # exports value as env var
SSL_CERT:    !tmp certs/ssl/mydomain             # creates temporary file and exports path as env var
SECRETS

# In our recipe we can use ENV['DB_PASSWORD'] and ENV['SSL_CERT'] where secrets are needed

# We have the Conjur CLI on the machine, so we can use conjur env

#!/bin/bash

# Creates a host identity using host-factory and places it in /etc/conjur.identity
# Requires the Conjur CLI and host-factory plugin to be installed
# Usage:
# ./hostfactory_bootstrap.sh 92198eb129peh812ue9puihd891 mynewhost1

For the saltstack tutorial, just install the [latest vagrant](https://docs.vagrantup.com/v2/getting-started/index.html) and use the below Vagrantfile to build a new vagrant box:

`Vagrantfile`
```
# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|
  config.vm.box = "ubuntu/trusty64"
 config.vm.provision "shell", inline: <<-SHELL

Outline

Application configuration

• Do you use config files for your app, or do you have a distributed solution? (etcd, serf, etc)

  If config files:

  • How do you set them up to work in multiple environments?

• How are they different for developer machines?

#! /bin/bash

# Checks that your Github repos are up to date

Terminal Cheat Sheet

---

pip

python package installer - look for packages on pypi

• pip install package_name - installs package from pypi
• pip install -r requirements file - installs packages from a requirements file
• pip uninstall package_name - uninstalls package
• pip freeze - output packages to stdout in requirements format, can be piped to a file

Python Protips

A collection of tips from things I've seen in a lot of code bases.

Use print() as a function and not a statement

print('some string') # good
print 'some string'  # bad

print() has been moved to a function in Python 3 docs.
