This directory contains the Vagrant environment for the Datadog 101 course on the Datadog Learning Site. To use this, make sure you have a working Vagrant environment. To find out more about setting up Vagrant, see https://www.vagrantup.com/.
For this course, you should create a new Datadog trial account. Go to https://app.datadoghq.com/account/login and click the Sign Up link. Step 3 of the signup process is Agent Setup. Click on any of the installation options and you will a command you need to run on a server. At the beginning of the command is DD_API_KEY. Copy the key and then add it to the file described below.
Create a file in your home directory called .ddtraining.sh with the following contents:
#!/bin/bash
DD_API_KEY="Your API Key Here"
Note: the file should have a new line after your API Key and your API Key should be wrapped in quotes.
With Vagrant running on your machine, clone this repo. Navigate to the Datadog101/VagrantMac directory. Any time you need to run a command on util or start or stop your vagrant environment, you should come back to this directory.
Run the following command to start your Vagrant environment:
vagrant up
It will take a few minutes to setup the five servers. This includes an HAProxy load balancer, three Apache webservers, and a utility server to run a load testing tool against the load balancer. The load balancer is reachable at http://localhost:8081. Try the URL and refresh a few times. You should see a different result each time.
Anytime you want to reset the environment to its original state, run this command:
vagrant halt;vagrant destroy -f;vagrant up
To stop the virtual machines you can either suspend them:
vagrant suspend
or halt them:
vagrant halt
There are two commands you can run on util: light and heavy. These are two different loads on the load balancer. I will let you guess which is which.
To login to util:
vagrant ssh util
To run light:
light
To run heavy:
heavy
