WHY AM I HERE?To sell my book ;)

To spread deployment process awareness

Discuss goals and steps for deployment

WHAT I'M NOT HERE FORTalk about deployment tools

Talk about server provisioning tools

Show you commands

Show you code

Discuss system specific things

WHY SHOULD WE TALK ABOUT THIS?It's about time we do it

Helps our entire development process

Gain confidence as a developer

THE PHP WORLD

PHP: a fractal of bad design

FUCK THE HATERS

EXCITING TIMES!Best practices

Testing

Continous integration

.. and even OOP

BUT...What happened to deployment in all this?

THE AGILE WORLDAgile: "Characterized by quickness, lightness,

and ease of movement."

Staying agile with deployment is about

RESPONDING QUICKLYTO FEEDBACK

Work in

SPRINTSbut plan for the

MARATHON

RELEASE CYCLESThe new version is done, ship it.

I'm done, ship it.

X amount of time has passed, ship it.

I pushed it, ship it.

ENVIRONMENTS

THE USUAL ONESLocal

Development

Staging

Production

(Testing)

QUESTIONSDo we have separate environments?

Are they repeatable/provisioned?

Do we have a branching strategy for our version control?

Staging as close to production as possible?

PITFALL #1This:

{ id: 1}

Can turn into this:

{ id: "1"}

PITFALL #2PascalCasedClass.php

class PascalCasedClass {}

index.php

require_once('Pascalcasedclass.php');

Will only work in enviroment that handles its file system case

insensitive.

I LIKE DIVERSITYAs long as it stays out of my software environments

THE STORY ABOUT AN APPLICATION.. come up with an idea

.. do some wireframes

.. code, code, code

.. celebrate finishing code

.. shit, we have to deploy it

.. well, do it quickly then

The deployment process is almost always

AD HOCA reaction to your applications state

"Duct tape deployment""

AUTOMATEEVERYTHING!

MANUL STEPSAre the root of all evil

AN EXAMPLE OF A MANUAL STEPclass Assets { const REVISION = 14;}

<link rel="stylesheet" href="style.css?v=<?=Assets::REVISION?>" type="text/css">

MATURITYA quite natural process (hopefully)

THE STEPSDocumentation
