Who Should Take This Course

• DevOps Engineers who want to move beyond traditional CI/CD and adopt a pull-based GitOps methodology.
• Platform Engineers responsible for building internal developer platforms (IDPs) using ArgoCD or Flux CD.
• Kubernetes Administrators looking to automate cluster state management and eliminate manual kubectl interventions.
• Software Developers who want to understand how their code reaches production through declarative Git workflows.
• Certification Candidates and professionals preparing for technical interviews who need to validate their GitOps knowledge through rigorous testing.

Prerequisites

• Baseline Kubernetes Knowledge: This course is not for absolute beginners; you should understand pods, services, and deployments.
• Container Fundamentals: A basic understanding of Docker or other container runtimes is required.
• Git Proficiency: Familiarity with basic Git commands (commit, push, pull, branch) is essential for success in this course.
• Basic YAML Knowledge: Ability to read and edit YAML files, as GitOps relies heavily on declarative manifests.
