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

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
