![]() Step 6 (Optional 6-node configuration): Starting the Second Nomad Cluster I will run a different process to start services automatically in another blog. The reason I’m detailing the manual clustering process is that this is meant for folks getting started. Launch the Nomad script with this command: sudo sh launch-a-3.sh.Connect via ssh to the third node using the command vagrant ssh nomad-a-3.Launch the Nomad script with this command: sudo sh launch-a-2.sh.Connect via ssh to the second node using the command vagrant ssh nomad-a-2.Launch the Nomad script with this command: sudo sh launch-a-1.sh. ![]() Change to the code folder with the command cd /vagrant.Connect via ssh to the first node using the command vagrant ssh nomad-a-1.It’s ideal if you have three (or six for a 6-node configuration) terminal sessions active so you can work Each node has a file named after the node name. Each VM comes up with the local Github repository mapped to the /vagrant folder inside the VM. The process is easy for this because we are using pre-made shell scripts that are included in the code. Once deployment is finished you’re back at the shell prompt and ready to start your cluster! Step 5: Starting the Nomad Cluster Once you run it once you also have the Vagrant box image cached locally so that saves time in the future for rebuilds. The whole build takes anywhere from 5-15 minutes depending on your speed of network and local machine resources. Next up is starting the deployment using the vagrant up command. Make sure that everything is all good by checking with the vagrant status command: Launch a terminal shell session (or command prompt for Windows) and change directory to the folder where you’ve cloned the code locally on your machine. The 3-node configuration only uses server-east.hcl by default. If you want to update the names of the regions or datacenter then you will do that by editing the server-east.hcl and server-west.hcl files. Picking your deployment pattern is done by renaming the configuration file ( Vagrantfile.3node or Vagrantfile.6node) to Vagrantfile The second configuration ( Vagrantfile.6node) will create two 3-node clusters across two virtual datacenters (toronto and Vancouver) and across two regions (east and west). One configuration ( Vagrantfile.3node) is a simple 3-node configuration with one region and a single virtual datacenter. Making the choice of your cluster and lab size is easy. Step 3: Configuring the lab for 3-node or 6-node If you want to contribute to the repository, you can also fork the repository and work from your own fork and then submit pull requests if you wish. Just go there and use the Clone or Download button to get the URL and then do a git clone command: The GitHub repository which contains all the necessary code is here: Oracle VM VirtualBox: or Step 2: Getting the Code There is no special configuration needed. Click these links to reach the downloads if you don’t already have them. Each are available free for many platforms. You’re going to need Vagrant and VirtualBox. I’ve built every step so that you can easily do this if you’ve got no experience. Now for the walk through to get you to show just how easy this can be! Skip ahead to whatever part of the steps you need below. Being able to provision, de-provision, start, and stop servers easily means you can save a ton of time and The reason I want to be able to quickly spin up local lab infrastructure is so I can get rid of the mundane repetitive tasks. Lover of open-source, learning, teaching, and life.One of the greatest things about open source and free tools is that they are…well, open source, and free! Today I’m sharing a simple HashiCorp Nomad lab build that I use for a variety of things. (Click here to see Gist version of this post.)

If you have VirtualBox installed, setup is easy. Vagrant is great for getting a predictable virtual machine set up with a few simple commands in a consistent and quick manner. There are plugins for talking to AWS, Azure, OpenStack, and many other services. Vagrant, by HashiCorp ( ), is a command-line interface to VirtualBox and numerous other virtual machine managers.
