SERVER PROVISONING | DELIVERY

• 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 or containers • Low frequency of changes to base images

SERVER PROVISONING | EVOLUTION

Artisan Server Crafting

Custom & Non-portable

Scripts

Automated & Standard CM

Tools

Immutable Servers & Unikernels

VMs, Chef, Puppet, etc.

Docker

Manual Installation, Documents

Shell scripts


• Artisan server crafting

– Boring

– Stressful

– Error-prone

– Time-consuming

– Non-scalable & expensive

• Too little time for things that matter

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

– Fast provisioning

– Keep servers in sync

• Puppet and Chef are examples of tools for automated configuration management


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 (trade-off)

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

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

MORE ON PUPPET | BUILDING BLOCKS

• Variables and (custom) facts

• Node declarations

• Classes and Modules

• Defined resource types

• Templates

• Puppet Forge

if $operatingsystem == 'CentOS'

node 'www1.example.com' {

include common

include ohs

}

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 | ARCHITECTURE

Central Chef Server

Multiple Administrators

Repository


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


CHEF | 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

DOCKER | INTRODUCTION

Docker allows you to create reusable “containers” with applications in them. These containers can be distributed and will run on several platforms.

• Container, not VMs and Hypervisor

• Linux-only

• Layering

• Provisioning speed, performance, smaller image size

• Dockerfile, Image, Container, Registry (build/ship/run)

• Maturity and security

26


DOCKER

• Docker and CM tools – Modify nodes versus wipe/create new nodes

– Abstraction and learning-curve

– Support for complex configurations

• Docker versus or together with CM tools?

– CM tool to provision Docker host and perform more complex provisioning inside Docker container

– Docker to create, distribute and run containers

– Docker to easily layer images (e.g. for demo’s)

• Oracle and Docker

– (Limited) support for Docker on Oracle Linux, WebLogic certified to run in Docker container

– Dockerfiles and Docker images (Oracle Linux, WebLogic)


TAKE-AWAYS | GENERAL

• Automate delivery

• Fundamental, not a value-add anymore

• Holistic approach on software delivery

• Not just technology, people and process as well

• Incremental approach

• No single tool that does it all

28

Do you need and want to do it yourselves?
