Continuous Integration is a software development practice where members of a team integrate their work frequently, usually each person integrates at least daily – leading to multiple integrations per day. -- Martin Fowler
Why CI?
Rapid Feedback
Reduced Risk
Collective Ownership
Continuous Deployment
Offload from people
Best Practices of CI
Single Source Repository
Commit often
Make Your Build Self-Testing
Automate the Build
Build fast
Jenkins
Extensible continuous integration server
What is Jenkins?
Open-source CI server
Easy to install and use
ExtensibilityOver 330+ plugins (230+ last year)More than 20,000 installations
Why Jenkins?
GUI to manage
Strong community and eco-system
Distributed builds
Open Source and Free!

Lots of people are using Jenkins...
Including Yahoo ;-)

Jenkins is still growing...
And the Job Trend is increasing

DEMO
Installation&Upgrade
Download Tomcat 6
Download jenkins.war
Put jenkins.war under webapps
Start Tomcat
Create a Job
Configure a Job
Configure Jenkins
Manage Plugins
Going Distributed
Need Isolation
Need Different environments
One Computer is not enough
Add Slave using JNLP
Java Web Start on slave initiates the sessionJenkins sends JNLP file and jar filesA separate socket connection is made
Add Slave using sshd
Master talks to sshd on a slaveSend slave.jar and “java -jar slave.jar”SSH session becomes bi-di byte stream
Some Distributed Issues
Different OS/Environment
Install required tools
System administration
Need to install slave manually
Tied Jobs to Slaves
Monitor Slaves
Monitor key metricsLow disck space and swapClock out of sync
Put offline automatically

Labels to Rescue
More on Label
Don't tied job to Slave, tied to Label
Label is a group of slaves
