Continous Integration @ MakeMyTrip

Concept

Standardization to minimize CI related ops.
CI system as code + infra that is scalable

Architecture

Docker oriented Infra
Jenkins master running as a Docker container.
Minimal configuration for slave machines as build are running over docker containers
Horizontally scalable
Pipeline based Jobs
Stage based execution time and status breakup.
Jenkins pipeline code is version controlled via Gerrit/Github

Auto-scaling & Build Time

Auto-scaling based on task queue
Provisioning of an instance in less than a minute
Auto-Termination if instance idle for >10 mins
CI Env dependencies spawned as Docker containers & executed within the Docker container.

Platform support

Java
Code quality via Sonar dashboards and Quality gates and unit tests
MMT Private Nexus dependency management
Assembly plugin
NodeJS
MMT private NPM repository for dependency management.
