A collection of exercises to build a simple deployment pipeline. This comes from the course I have taught in DevOps and is targeted at instructors or individuals who want to learn the basics of a pipeline.

1. My First Deployment
Pipeline

2. What is inside
A deployment pipeline is a series of tools that takes code
from commit to a repository to production
I will describe a series of exercises that results in a simple
deployment pipeline constructed from open source
resources
If you do the exercises, you will :
Learn the basic elements of a simple deployment pipeline
Gain some familiarity withVirtualBox,Vagrant, Git, Jenkins, and
Ansible and their roles.

3. Tools in Context
Git, Jenkins andAnsible must execute on a platform
• The platform for these exercises isVirtualBox
• Vagrant is a tool to help create the platform

5. VirtualBox and Ubuntu
• VirtualBox is a tool for creating and managingVirtual
Macchines
• Download from
https://www.virtualbox.org/wiki/Downloads
• Ubuntu is a widely used Linux platform
• Download latest 64 bit version forVirtualBox from
http://www.osboxes.org/ubuntu/

6. Exercise
• Create two UbuntuVMs inVirtualBox that can ping each
other
• Learning outcomes:
• Ip addresses
• Difference between virtual image and virtual machine

7. SSH
• OpenSSH is a tool for managing Secure Shell
connections.

8. Exercise
• Set up the twoVMs created in the previous example so
that you can ssh from one to another
• http://sshkeychain.sourceforge.net/mirrors/SSH-with-Keys-
HOWTO/SSH-with-Keys-HOWTO-4.html
• https://help.github.com/articles/generating-a-new-ssh-key-and-
adding-it-to-the-ssh-agent/
• Learning outcomes
• Identifying known users

9. Git and Sample App
• Petclinic is the app you will be deploying
• http://docs.spring.io/docs/petclinic.html
• Git is the version control system you will use.
© Len Bass 2015 9

10. Exercise
• Install Petclinic on one of theVMs previously created
http://graphwalker.org/docs/pet_clinic
• This will require Java
http://stackoverflow.com/questions/14788345/how-to-
install-jdk-on-ubuntu-linux
• Learning outcomes:
• Packaging Java applications
• Building Java applications

12. Vagrant
• Vagrant is a tool for creating and managingVirtual
Machines
• https://docs.vagrantup.com/v2/getting-
started/index.html
© Len Bass 2015 12

13. Exercise
• CreateVagrantfiles to perform theVM operations done
manually usingVirtualBox
• TwoVMs where one can ssh to another
• Petclinic
• Learning outcomes:
• Automating repetitive tasks

15. Jenkins
• Jenkins is a tool used for building and testing code. It
contains orchestration features and a large number of
plugins that enable it to interact with many other tools.

16. Exercise
• UseVagrant to set up a Jenkins build server
• Use Jenkins to build and make available Petclinic.war on
the Jenkins build server
• Learning outcomes:
• Orchestration of different activities

17. Ansible
© Len Bass 2015 17

18. Ansible
• Ansible is a tool for managing fleet deployments
• https://www.ansible.com/
© Len Bass 2015 18

19. Exercise
• Use Ansible to deploy the Petclinic.war on the Jenkins
build server to a secondVM (simulating a fleet)
• Learning outcomes:
• Control of a collection ofVMs by another
© Len Bass 2015 19

20. Conclusion
• Git+Jenkins+Ansible is your first deployment pipeline
• Vagrant is used to create theVMs used in the pipeline and
the target deployment machines.
