Getting Started with HashiCorp Nomad

Nomad, a flexible scheduler and workload orchestrator, allows organizations to deploy and manage any containerized or legacy application using a single, unified workflow. This course introduces Nomad's key features, including container orchestration, service discovery, and multi-cloud deployment. You'll learn to: - Install and configure Nomad, set up a cluster, and integrate it with HashiCorp tools like Consul and Vault. - Deploy and manage applications on Nomad across platforms, as well as scheduling, resource allocation, and rollouts. - Using the UI, you'll create job specifications, run your first Nomad job, and manage and monitor the environment and application logs. - Create a rotating gossip encryption key and upgrade Nomad. Troubleshooting and debugging in production are included. By the end, you'll be proficient in using Nomad to automate workflows. The course, ideal for software engineers, system administrators, and DevOps professionals, requires basic Linux OS, command-line, cloud computing, and containerization knowledge. Prior experience with tools like Docker, Kubernetes, or HashiCorp Vault is recommended.

• Introduction to Nomad
• In this module, we will provide a comprehensive introduction to Nomad, starting with its fundamental concepts and purpose. We will delve into the key components that constitute Nomad, explore its architecture, and highlight how it operates. Finally, we will compare Nomad to Kubernetes, emphasizing the unique features and commonalities between the two platforms.
• Deploying Nomad
• In this module, we will guide you through the process of deploying Nomad across various platforms, including macOS, Linux, and Windows.
