Argo CD
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes that automates the deployment of applications to clusters. It monitors Git repositories containing application manifests and synchronizes the live state in Kubernetes to match the desired state defined in Git. This enables developers to manage infrastructure and application deployments through version-controlled configuration files.
Developers should use Argo CD when implementing GitOps workflows for Kubernetes deployments, as it provides automated synchronization, rollback capabilities, and audit trails. It is particularly valuable in multi-cluster environments, CI/CD pipelines, and scenarios requiring compliance and reproducibility, such as in regulated industries or large-scale microservices architectures.
