Hands-On Continuous Integration and Automation with Jenkins - Run Jobs on a Slave Node

This video tutorial demonstrates configuring and running a Jenkins job on a slave node. It covers setting up a Freestyle Project, executing shell commands, and monitoring the provisioning of a slave node. The tutorial also explains how to clean up AWS resources to avoid unnecessary costs. The video concludes with a recap of the master-slave architecture in Jenkins and AWS concepts, encouraging viewers to test their knowledge through exercises in a GitHub repository.

What is the first step in configuring a Jenkins job to run on a slave node?

• Select the project type as Pipeline

• Enter an item name and select Freestyle Project

• Configure the build environment

• Add a post-build action

What command is used in the build step to print a message on the console?

• Log 'Hello, slave nodes'

• Print 'Hello, slave nodes'

• Echo 'Hello, slave nodes'

• Display 'Hello, slave nodes'

What message indicates that Jenkins is provisioning a slave node?

• Slave node is online

• Pending: Jenkins doesn't have label slave

• Build failed

• Job completed successfully

How can you verify that a new EC2 instance has been launched for the slave node?

• Check the Jenkins console output

• Review the Jenkins job configuration

• Look for a new instance in AWS EC2 instances with the label 'Slave'

• Monitor the Jenkins build status

What should you do to avoid unnecessary costs after completing the Jenkins job?

• Increase the idle time for the slave node

• Leave the EC2 instance running

• Terminate the EC2 instance and release the Elastic IP

• Keep the slave node active

What is the idle time set for the slave node before it is automatically decommissioned?

• 2 minutes

• 5 minutes

• 10 minutes

• 15 minutes

What theoretical concept was covered in this section related to Jenkins?

• Jenkins security settings

• Jenkins plugin development

• Jenkins pipeline configuration

• Master-slave architecture
