Container Orchestration with Nomad by HashiCorp

Introduction

Nomad by HashiCorp is a versatile orchestrator that simplifies the deployment and management of applications, whether they’re containerized, virtualized, or standalone. Implementing Nomad on ServerStadium’s infrastructure (VM Pricing, Dedicated Servers) enables efficient scaling and management of applications.

Prerequisites

  • A ServerStadium VM or dedicated server (VM Pricing, Dedicated Servers).
  • Basic knowledge of containerization and server management.
  • Familiarity with command-line interface operations.

Step 1: Set Up Your ServerStadium Server

  1. Choose a Server: Select a ServerStadium server based on your application requirements in terms of CPU, memory, and storage.
  2. Server Preparation:

    sudo apt update
    sudo apt upgrade

Step 2: Install Nomad

  1. Download Nomad:

    Download Nomad from the official HashiCorp releases page:

    wget https://releases.hashicorp.com/nomad/1.1.3/nomad_1.1.3_linux_amd64.zip

  2. Install Nomad:

    Unzip and install Nomad:

    unzip nomad_1.1.3_linux_amd64.zip sudo mv nomad /usr/local/bin/

Step 3: Configure Nomad

  1. Create Nomad Configuration:

    Set up Nomad’s configuration file:

    sudo mkdir -p /etc/nomad.d sudo nano /etc/nomad.d/nomad.hcl

    Configure Nomad as per your requirement (server, client, data directory, etc.).

Step 4: Start Nomad Server

  1. Start Nomad:

    Initiate Nomad in either server or client mode:

    sudo nomad agent -config /etc/nomad.d/nomad.hcl

Step 5: Deploy Containerized Applications

  1. Create a Nomad Job File:

    Define a job in a Nomad job file (e.g., myapp.nomad):

    job "myapp" { // Job configuration }

  2. Run the Job:

    Deploy your application:

    nomad job run myapp.nomad

Step 6: Monitor and Scale Your Applications

  1. Monitor Applications:

    Use the Nomad CLI or UI to monitor the status of your applications.

  2. Scaling:

    Scale up or down based on the demand, directly through Nomad’s configuration files or UI.
