Quickstart for continuous integration
2 likes1,964 views
This document provides an introduction to continuous integration (CI), including its objectives, benefits, and how to get started with CI. CI aims to integrate components, software, and infrastructure through short, frequent integration cycles to reduce integration problems and improve productivity. Benefits include anticipating risks early, reducing errors, providing fast feedback, lowering release stress, and enabling collaboration. The document recommends choosing build and scripting tools, using a configuration management system, selecting a CI tool like Jenkins, and setting up a CI "playground" for testing. It provides examples of configuring projects and jobs in Jenkins along with collecting build statistics, reports, and notifications.

Quickstart for continuous integration
- 3. Continuous Integration objectives 3 • Support team work integration: • Component x Software x Infrastructure • Anticipate integration phase • Short & fast integration cycles • Significantly reduce integration problems and allows a team to be more productive. • Accelerate software development and release 01
- 4. Benefits 4 • Anticipating risks • Early execution of the integration cycle, not only at the pre-release stage. • Radically reducing errors • Test practice leads to product maturity. • Fast and continuous feedback • Reporting, metrics and status in minutes, not hours or days. • Lowering release stress • Release in a few weeks not months • Powering cross-team collaboration • Self-service builds for developers, testers, operations, business people and others 01

- 6. How do I start? 02 Getting started! Build & Scripting Tools " Configuration Management # CI Tool > Playground % Code Repository
- 7. Code Repository 702 % Private hosting Hosting sites github.com bitbucket.org code.google.com sourceforge.net assembla.com
- 8. Building & Scripting 8 ! Building Scripting • Tasks automation: operating system tasks, releasing steps, publishing artifacts, deployment scripting • Dependency Management • Build • Test • Packaging • Deployment 02 Do not rely on IDE settings, use Command-Line Interface (CLI) like a boss
- 9. Choosing the right toolkit 9 Building Tools Scripting Languages Platform based Windows batch Linux bash, shell Object-oriented Ruby JavaScript Python Groovy Javascript: Grunt, Gulp Java: Ant, Maven, Gradle .NET: MSBuild ! 02
- 10. Configuration management 10 " • Externalized application configuration: files, environment variables, etc. • Define multiple application configuration profiles • Local development & unit testing • CI build & integration testing • Releasing for staging, production • Integration tests may require some external tools and database setup. 02
- 11. Sample grails data source configuration 11 " 02
- 12. Playground 12 > Dedicated Machine Distributed CI Server + App build stack+ App runtime stack CI Server App X stack App Y stack Server-side infra structure models Q External Devices 02
- 13. Playground: Keep it Simple 13 > • Virtualize wherever possible • You can found some VMs ready to use on the market: Amazon AWS, Bitnami.com… • Keep a manifest file for the application stack, aka README • Minimum software requirements • Operating system version • Configuration updates • Installation steps • build stack • runtime stack 02
- 14. CI by Jenkins 03 Practice
- 15. Configuring a CI system with Jenkins 15 • Building/testing software projects continuously • Monitoring executions of externally-run jobs 03 What is Jenkins? jenkins-ci.org
- 16. Create a Job / Task 16 • Parameters • Pre-conditions • Source Code • Triggers • Build steps: • No tricks here please • Just call the scripts and tools • Treat scripts as source code • Post conditions • Post build tasks 03
