Example 1
===============================
Maps are a way to create variables that are lookup tables. An example will show this best. Let's extract our AMIs into a map and add support for the us-west-2 region as well:

variable "amis" {
  type = "map"
  default = {
    "us-east-1" = "ami-b374d5a5"
    "us-west-2" = "ami-4b32be2b"
  }

Summary of book "Clean Architecture" by Robert C. Martin

Uncle Bob, the well known author of Clean Code, is coming back to us with a new book called Clean Architecture which wants to take a larger view on how to create software.

Even if Clean Code is one of the major book around OOP and code design (mainly by presenting the SOLID principles), I was not totally impressed by the book.

Clean Architecture leaves me with the same feeling, even if it's pushing the development world to do better, has some good stories and present robust principles to build software.

The book is build around 34 chapters organised in chapters.

Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

Overview
========
Students in my Web Programming class (G. Brown, S. Prassad, et al)
discovered that MongoDB request injection attacks also work on Node.js
+ Express web applications.  MongoDB request injection attacks have
been known for PHP web applications.

Impact
======
Attacker can view and download all the data in a MongoDB database

# In Chef, when a resource is defined all its variables are evaluated during
# compile time and the execution of the resource takes place in converge phase.
# So if the value of a particular attribute is changed in converge
# (and not in compile) the resource will be executed with the old value.

# Example problem:
# Let's consider this situation where there are two steps involved in a recipe
# Step 1 is a Ruby block that changes a node attribute. Rubyblocks get executed
# in converge phase
# Step 2 is a Chef resource that makes use of the node attribute that was
