How to Install Nomad on Elementary OS Latest

Nomad is a modern and flexible cluster manager that can run any workload on any infrastructure. In this tutorial, we will be installing Nomad on Elementary OS Latest.

Prerequisites

Before we begin with the installation, we need to have the following prerequisites:

• A running instance of Elementary OS Latest
• A user account with sudo privileges

Step 1: Update the System

It is always recommended to update the system to its latest version before installing any new package. To update the system, run the following command in the terminal:

sudo apt update && sudo apt upgrade

This command will update the package list and upgrade the installed packages to their latest versions.

Step 2: Download and Install Nomad

To download and install Nomad, follow the below steps:

1. Download the latest stable version of Nomad from the official website using the following command:

   curl -fsSL -o nomad.zip https://releases.hashicorp.com/nomad/0.12.7/nomad_0.12.7_linux_amd64.zip
   

   This command will download the latest version of Nomad to your system.

2. Extract the downloaded file using the following command:

   unzip nomad.zip
   

   This command will extract the downloaded file to a new directory named "nomad".

3. Now, move the extracted directory to the "/usr/local/bin" directory using the following command:

   sudo mv nomad /usr/local/bin/
   

   This command will move the extracted directory to the "/usr/local/bin" directory, which is already included in the system's PATH environment variable.

4. Verify the installation by running the following command:

   nomad version
   

   This command will display the current version of Nomad installed on your system.

Step 3: Configure Nomad

After installing Nomad, we need to configure it properly before using it. Follow the below steps to configure Nomad:

1. Create a new directory for the Nomad configuration files:

   sudo mkdir /etc/nomad
   

2. Change the ownership of the new directory to your user account:

   sudo chown $USER:$USER /etc/nomad
   

3. Create a new configuration file for Nomad:

   nano /etc/nomad/nomad.hcl
   

4. Paste the below configuration in the file and then save and close it:

   data_dir = "/tmp/nomad"
   log_level = "INFO"
   
   plugin "raw_exec" {
     config {
       enabled = true
     }
   }
   

5. Restart the Nomad service to apply the new configuration:

   sudo systemctl restart nomad
   

Step 4: Verify Nomad Installation

Now that we have installed and configured Nomad, it's time to verify the installation. Follow the below steps to verify the installation:

1. Check the status of the Nomad service using the following command:

   sudo systemctl status nomad
   

   This command will display the current status of the Nomad service.

2. To see the Nomad dashboard, open a web browser and go to the following address:

   http://localhost:4646
   

   This will open the Nomad dashboard, where you can see the status of the Nomad cluster and deployed jobs.

Congratulations! You have successfully installed Nomad on Elementary OS Latest. You can now use Nomad to manage and deploy workloads on your infrastructure.
