Argo CD is an open source, declarative, GitOps-based CD tool designed to automate deploying and managing applications and infrastructure on Kubernetes clusters. Argo CD serves as a robust application controller, efficiently managing and ensuring the smooth and secure operation of your applications. Argo CD works in the pull-based GitOps model and, therefore, polls the Environment repository regularly to detect any configuration drift. Suppose it finds any drift between the state in Git and the actual state of applications running in the environment. In that case, it will make corrective changes to reflect the desired configuration declared in the Git repository.

Argo CD is tailored explicitly to Kubernetes environments, making it a popular choice for managing applications on Kubernetes clusters.

In addition to the traditional Kubernetes manifest YAML files, Argo CD offers support for various alternative methods of defining Kubernetes configurations:
