🚀 GitOps: Infrastructure Automation with Git

"Declarative, automated, and version-controlled deployments."

GitOps is a modern infrastructure management approach that leverages Git as the single source of truth for defining and deploying applications and infrastructure. This methodology enables seamless, automated, and consistent deployments while maintaining high visibility and control.

🔹 Key Principles of GitOps

✅ Declarative Configuration – Define infrastructure and application states in code.
✅ Version Control as Source of Truth – Store all configurations in Git repositories for tracking changes.
✅ Automated Deployments – CI/CD pipelines continuously sync deployments to match the defined state.
✅ Observability & Auditing – Every change is logged and versioned for full visibility.

🛠️ GitOps Tools in My Stack

🔹 ArgoCD – A declarative GitOps continuous delivery tool designed for Kubernetes.
🔹 Jenkins – Automates CI/CD pipelines, integrating GitOps workflows for deployments.
🔹 FluxCD – Kubernetes-native GitOps tool for managing clusters and workloads.
🔹 Helm – Package manager for Kubernetes, used alongside GitOps to simplify deployments.
