The Goal For Using CI/CD

Deliver code safe & fast from SVC to production

Tools Set● BitBucket● Jenkins● Docker● Registry● Consul● RabbitMQ● Mesos● Redis● And some code...

Conventions

Examples

● Projects Names: py-appsflyer-backoffice, Node-af-dashboard-data

● Projects Modes: clicks,launches,etc...● Instance names: webh-20001-001-prod● Container names: afwebhandler_webh-20001-

001-prod.eu1.appsflyer.com

Build Flow

Scaling/HA of the build infrastructure

● Jenkins ● Builders● Rabbit● Redis● Registry

Active/passive master + horizontal scaled slaves

Scale out docker builders cluster

Rabbit cluster for HA

Master/Slave Redis with sentinel for auto switch over

Active/passive with automatic switch over

Demo-1: Builds

Deploy Flow

Types Of Operations● Deploy● Start● Stop● Restart● Revert● Build/Deploy Branch● The above actions on specific instances● The above actions on several modes● Deploy to Mesos● And more…

Auto Healing

Saving Money

Demo-2 Deployment

The Needs for PAAS

● Easier for branch testing● Smoother testing→staging → production flow● Ideal for small applications● Faster delivery● More dynamic● Less configurations● Potential for better utilization
