Puppet - Resource

So weird:
Resources are not subject to scope — a resource in any scope may be referenced from any other
scope.

Cloud Work - Overview

Big Picture

The 3 main building blocks are:

1. IDAM Cloud - We provide more specific support for PI that Nibiru doesn't provide OOB.
2. Nibiru - Wraps AWS and provides some basic functionality.
3. AWS - The physical infrastructure that our VMs live on.

Creates and Configures Cloud Infrastructure

• Provisioning VMs - API Nodes, Mongo Nodes, Supporting Infrastructure Nodes
• DNS
• AB Stack
• Load Balancing - ELBs and HAProxy
• Monitoring
• Alerting
• Logging

Tools we rely on

We rely on a lot of different tools, including:

• Fabric
  • A tool written in Python for easing interactions with remote servers.
  • Essentially acts as our CLI for interacting with our Cloud Environment.
  • Interacts with Nibiru via their Python restful client.
• Nibiru
  • An abstraction layer around AWS
  • CRUD ops on VMs
  • CRUD ops on DNS entries
  • CRUD ops on ELBs
  • Applies some default Puppet Modules to our VMs:
    • Zabbix
    • what else?
• Puppet
  • For configuring our VMs with the appropriate resources to act as a particular VM type.
  • Applies Modules such as:
    • MongoDB
    • Tomcat
    • StatsD
    • Thalassa
    • ElasticSearch
    • Graphite
    • HAProxy
    • Logstash
• Zabbix
  • For monitoring, alerting and visualizing information about VMs
• Sensu
• Logstash
• StatsD
• CollectD
• Graphite
• Vagrant

Stack

• vagrant up
• runs a bootstrap shell script
• uses apt-get to install:  puppet, pip, git
• uses gem to install:  puppet-lint, r10k
• uses pip to install python modules:  fabric, mock, nose, coverage, nosexcover, flake8, autopep8
• runs a fab task to install puppet dependencies (using r10k & a puppetfile)
• puppetfile supports both puppet forge & github
• runs a fab task to create a config file with information about the vm
• runs a fab task to finally run a puppet-apply

Vagrant -> vagrantfile
Puppet -> puppet.conf
Hiera -> hiera.yaml
r10k -> Puppetfile
Python -> setup.cfg

Programming Quotes

There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult. --Tony Hoare

Fan Base

Okay, I guess I officially realized I may have a small fan base.

A few of my posts have actually gotten a   +1

Neat.

Ping Pong - probably an illegal paddle

Broke the handle off a paddle...
Replaced it with a double-length handle and wrapped it with a new tennis racket grip.

Cut a handle and cross beam on the radial arm saw... then whittled the handle a bit with a box cutter to round it out some and then sanded the handle with an electric sander.
Drove two long thin screws up through the cross beam into the paddle head.
Drove one  long fat screw through the cross beam into the handle.

Monitoring - Zabbix Part 2

been programming against zabbix 1.8 api for like 2 weeks.
its very 'enterprise-y'
creating host groups, templates, items, triggers
creating applications and web items
creating user groups and users and actions
