Argo CD

• It's a deploy mechanism based on GitOps principles and designed for Kubernetes
• Argo CD uses the Declarative deploy approach (do something until you achieve the desired state)
• Manually applying via kubectl is the Imperative deploy approach
• Git repository contains the manifests with the desired state, which is now the source of truth
• Argo CD uses the pull model
