DevOps - virtualization

Preparation

1. Fork the https://github.com/szatmari/devops-virtualization project
2. Start a "DevOps - virtualization" in the BME cloud

Vagrant basics

1. Setup project folder

mkdir myVagrantProject; cd myVagrantProject

2. Init vagrant project

vagrant init hashicorp/precise32

3. Limit CPUs to 1

  config.vm.provider "virtualbox" do |vb| 
    vb.cpus = 1
  end 

4. Start the project

vagrant up
vagrant ssh
ls /vagrant

5. Check the Vagrant cloud service: https://app.vagrantup.com

VirtualBox

1. Check the running vms

vboxmanage list vms

Deployment using Jenkins

1. Map the port 8080 to the public interface in the BME Cloud Manager
2. Visit the generated endpoint
3. Create a new freestyle job
   • Set your GitHub link to your project
   • Configure SCM: git
   • Add your repository URL
   • Set the "Branches to build" property to "*/master"
   • Add "Invoke gradle script" to the Build section
   • Set the gradle task: "build"
   • Add a Post Build action: Publish Junit test results
   • Set the path of the "Test report XMLs" to "build/test-results/test/*.xml"
4. Check the Vagrantfile in the project
5. Add a new build task to do deployment: "Execute shell" and execute Vagrant Up!

vagrant up

6. Try to enter to the VM console and start your application

sudo su jenkins -s /bin/bash
cd /var/lib/jenkins/jobs/%%myDevOpsJob%%/workspace
vagrant ssh

7. Check the Packerfile and the content of the packer folder in the project
   • Check the Ubuntu AMI locator for AWS: https://cloud-images.ubuntu.com/locator/ec2/
8. Try the packer builder using an other Execute shell build step

packer build -var 'aws_access_key=XXXXXXXXXXX' -var 'aws_secret_key=XXXXXXXXXXXXX' Packerfile
