This is NOT a Tutorial



What is Dev Ops anyway?



Why is Dev Ops Important?



1. DevOps will make you a better developer.



2. DevOps will help you deliver better work to your clients



3. DevOps helps move WordPress into bigger companies and opportunities



How Does Dev Ops Help?


1. Collaboration

2. Code Sharing

3. Automation


1. Collaboration



Version Control


Easy for developers to collaborate

A hardened nuclear bunker for your source code

Makes it easy to have more that one version of your project!

Basically a time machine


What is a “Commit”?



Merging Version Control


- Gives you the ability to manage different versions of your software

- Development, Staging & Production

- Approve code to move up the versions into production


2. Code Sharing



Dependencies



WordPress Has Dependencies


- Diff by Geoffrey T. Bairiki

- ID3 by James Heinrich

- BackBone & Underscores


The Problem with dependancies is that they can change



What About Your Project?



Your Dependancies - have dependencies



What About Your Project?



This Sounds Like a Nightmare

Can Bite You



Easy Ways To Get Started



3. Automation



Repetition Sucks


Mistakes Get Made

People Get Bored

Creative people usually don't like to do the same thing over and over again.

Not a good use of skills and talent


Need to do it twice?



Need to do it twice?

Automate it.



Good Candidates for Automation


Deployments

Compiling Assets (Sass, CoffeeScript, etc)

Compressing Images

Setting up servers

Installing WordPress


I Hate FTP



Automated Deployments


No more slow or failed FTP transfers

Easily tied into your version control

Easily undo a mistake

Get new code into production with a few key stokes or clicks

Capistrano


- Scriptable and self-installed

- Ruby

- Task Based

- Logs in to your server, pulls from your Version Control, runs a series of tasks

you tell it to.

- Super powerful and flexible


Deploy HQ Deploy Bot Buddy

DeployBot (etc)


- Many of these services exist

- Hard to configure but just works when its done

- $/£/€

- Less control and less flexible but easier to setup


Standardising Environments



Use Virtual Machines

Concluding



Its going to take a while



These aren’t WordPress Skills



They are Professional Development Skills



Where To Go Next?


- Automated Testing (Never ship something broken again)

- Visual Regression Testing (Make CSS changes less painful)

- Code Quality Checks (Stop bad code getting into your repo or near a server)

- Install Software on your servers with a few keystrokes

- Notifications and Integration with your other tools
