! Continuous Integration !   Each commit or per batch, the source code is :

!   Compiled !   Tested !   Deployed on Integration environment

! Continuous Delivery !   Each commit or per batch, the source code is :

!   […] !   Delivered to next team (QA, validation, production, …)

! Continuous Deployment

!   Each commit or per batch, the source code is : !   […] !   Deployed on Production environment

1- Two things

ü Source repository

ü One machine to build

How ?

10

2- Many principles to apply :

ü Maintain a code repository ü Automate the build ü Make the build self-testing ü Everyone commits more often ü Everyone can see the results of the latest build ü Automate deployment

How ?

Samples (for the backend)

1 deployment per day

~10 deployments per day



1 deployment every 11 seconds

! Continuous deployment, not continuous delivery ! Many factors prevent from doing continuous delivery

!   On iOS and WP the Store validation process !   On Android the regression testing process is long

!   Facebook is going for crowd testing on Android !   Android Beta Program

!   New releases are marketed towards the users and they expect them ! !   “42 new levels for Candy Crush !” !   “A new hero in Clash of Clans !” !   “A new budget feature for my mobile banking app !”

! The emerging standard is going to release every month

What about mobile Apps ?

15

! Improve TTM and feedback in real life

Why deploy continuously ?

! Deploy every day at 4PM to the product team

! Product team come on the open space at 4:30 and give feedbacks

Meetic sample

17

! By decreasing deployment size !  Minimize risks !  Reduce the Mean Time To Repair (MTTR)

And quality ?

18

Installing Jenkins

! Manual Installation

!   Install Java ! Download jenkins.war !  Start the server

! Directly java –jar jenkins.war

!  Or with a Java Web Application Server !  Jenkins is accessible at : http://localhost:8080/

19

http://localhost:8080/

20

Install plugins

21

Distributed jobs

! Sometimes the CI Server can’t execute the build directly on the server !  For example on windows it’s impossible to build

Objective-C source code, you need a Mac for that.

! It’s the master/slave notion

MASTER SLAVE

execute the build on
