MongoDB Pillar Walkthrough

# Infrastrucutre Data Example:
 
infrastructure:
  name: Some Infrastructure
  id: 123
  enabled_environments:
    - staging
    - development
  backups: true
  size_resources:
    mem: 512MB
    cores: 1
    hdd: 20GB
  high_availability:
    enabled: true
    web_nodes: 2
    load_balancers: 1
  caching: true
  platform: wordpress
  sites:
    somesite.com:
      multisite: false
      docroot: /var/www
      envs:
        - staging:
            domain: somesite.stag.almost.online
        - development:
            domain: somesite.dev.almost.online

# Insert Infrastructure data into Mongo under its ID:

db.pillar.insert({
	  _id: 'inf-123',
	  mongo_pillar: {
	      < the data above >
	  }})

# Orchestration (psuedo code):

Ex. 2 webs nodes + lb  with template inf-<inf id>-role-<role num>:

var pillar = salt ‘inf-123’ pillar.items

salt-run state.orchestrate orch.ha_web_setup pillar = pillar

## ...loops run, nodes are created for a given infrastrucutre orchestraion...

## Creates:

inf-123-webserver-1
inf-123-webserver-2
inf-123-loadbalancer-1

# Highstate

## Salt passes these to Mongo Pillar Module:

inf-123-webserver-1
inf-123-webserver-2
inf-123-loadbalancer-1

ext_pillar:
  - mongo: { … re_pattern: inf-\d+-\w+-\d+ … }

# Would these pillars match up?
