Working with ansible-vault

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.

Lotus Console

A simple rake task that replicates the rails console for Lotus Framework

How to?

I assume that your config/application.rb is the place where you initialize all Lotus boot config

below is my config/application.rb for your interest

###Measuring performance

Monitor the values of specific code paths and graph them to see performance over time (response times as one example metric)
Automated tests that measure performance can fail based on a set threshold
- If a given code path exceeds 20% of the existing response time, then the automated test fails, alerting ops and devs that a recent code change has negatively impacted performance beyond an pre-defined SLA or threshold
Need a production like environment
Make that performance test environment exclusive to performance testing (don't let regular usage or QA usage affect the test results)
