Welcome and greetings
- Hello, and welcome to today’s episode. A very special welcome and thank you to our listeners in Enterprise, Alabama.
Recap of last episode
- In our last real episode, we discussed Hashicorp’s Vagrant product. I talked a little bit about what it is and how it can be used to improve and speed up your automation efforts….especially around server provisioning.
Summary of this episode
- In this episode, I’m going to talk about how you can further enhance automation with Vagrant by using a Vagrantfile. I’m going to cover 3 examples of how a Vagrantfile can be used in different ways to provision a server.
What’s in it for you?
- At the end of this episode, you will be able to discuss with your peers and co-workers how you can use Vagrant and Vagrantfiles to further your automation efforts. You will see how to set up a basic Vagrantfile and some of the syntax that goes into setting up the commands to successfully create the server(s) that you need for your application and environment.
Here are the 3 examples that I cover in this episode. Having this in front of you as a reference will help you understand some of the commands that I cover.
# Begin examples.
– Create an empty directory.
– Copy the above file to it as Vagrantfile.
– Install Vagrant and VirtualBox if you don’t have them yet.
– Using “cd”, change to the directory and run “vagrant up”. It will take a while to download the image and then to install Jenkins in the image.
– Then on your computer browse to http://localhost:8080/ Jenkins will prompt you for the secret admin password that was set up during installation.
– On the command line, type “vagrant ssh” this will ssh into the VirtualBox running Jenkins.
– Type “sudo cat /var/lib/jenkins/secrets/initialAdminPassword” to get the secret, copy that secret to the browser.
– Just use the default installation parameters, then create a user for the admin user.
– If you don’t see the jenkins screen, then restart the machine by typing in “sudo reboot”.
– Once the machine has rebooted, you can reload the page in the browser and it should show you the Jenkins login page.
# Example # 1
# vi: set ft=ruby :
Vagrant.configure(“2”) do |config|
config.vm.box = “ubuntu/bionic64”
config.vm.network “forwarded_port”, guest: 8080, host: 8080, host_ip: “127.0.0.1” ### this should be the IP of the host that vagrant is running on.
config.vm.provision “shell”, inline: <<-SHELL
apt-get upgrade -y
wget -q -O – https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add –
sh -c ‘echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list’
apt-get install -y openjdk-8-jre
apt-get install -y jenkins

Recap of this episode
- In this episode, we reviewed how to set up and use a Vagrantfile to enhance your automated server provisioning. This will be valuable if you need to stand up an isolated server instance for a particular type of testing when you don’t have the time or money to purchase a new bare-metal server and get it into your data center and network.
