SERVER PROVISIONING

7 | x

• Automated installations and rollbacks • Inject environment variables, smoke-testing

• Automated builds, tests, and packaging from version control • Central archiving in repository or artifactory

• Automated provisioning of middleware • High frequency of changes to servers (e.g. patches)

• Automated provisioning of OS-ready images • Low frequency of changes to images

● Error-prone

● Time-consuming

● Non-scalable & expensive

Server provisioning | how it can be

Automated configuration management

● Describe a system once, apply as often as you want

● Automate the repetitive, focus on improvements

and “real” problems

● Predictable results

● (Near) real-time provisioning

● Keep servers in sync

12 | x

Server provisioning | infrastructure as code

Advantages

● Configuration is documentation and always up-to-date

● Configuration is version controlled

● Configurations are defined in a machine- and OS-independent domain

language so the manifests are portable and can be reused

● Change and test configuration, not the server, and re-apply

PUPPET

Introduction to

14 | x

Puppet Example | Apache HTTP Server

package { "httpd":

name => "httpd.x86_64",

ensure => "present",

}

file { "http.conf":

path => "/etc/httpd/conf/httpd.conf",

owner => root,

group => root,

mode => 0644,

source => "puppet:///modules/apache/httpd.conf",

require => Package["httpd"],

}

service { "httpd":

ensure => running,

enable => true,

subscribe => File["http.conf"],

}

● Manifests

● Resources

• Name

• Attributes and

values

● Ordering and

dependencies

15 | x

More on Puppet | building blocks

● Variables and (custom) facts

● Node declarations

● Classes and Modules

● Defined resource types

● Templates

if $operatingsystem == 'CentOS'

node 'www1.example.com' {

include common

include apache

}

node 'db1.example.com' {

include common

include oraclexe

}

file { "http.conf":

path => "/etc/httpd/conf/httpd.conf",

owner => 'root',

group => 'root',

mode => '0644',

content => template('config/httpd.erb'),

}

Chef | terminology

● Node, Server, Workstation

● Chef-client asks Chef-server about the policy for the node

● Resources: a component and the desired state

● Recipes: describe resources and desired state

● Cookbooks: sets of recipes grouped together, also includes templates

and source files, etc.

● Run List: recipes from cookbooks you want to run

● LWRP: custom actions

23 | x

Example Recipe

paca

Policy says package

should be installed

This service should be

enabled on reboot, and

must be running

Template specifies the

contents required
