Build a GitOps Pipeline to Deploy a Three-Tier Application

Learn to implement GitOps principles by building a complete deployment pipeline for a three-tier block-stacking game application in this 58-minute hands-on lab. Deploy both the application and its underlying Nomad cluster infrastructure using Git-based version control and automation workflows. Master the integration of multiple HashiCorp tools including Terraform for infrastructure provisioning, Packer for image building, Nomad for workload orchestration, Consul for service discovery, and Vault for secrets management within a unified GitOps approach. Practice editing infrastructure and application code through version control, then automatically deploying changes to create a seamless development-to-production workflow that demonstrates modern DevOps practices for multi-cloud environments.
