GitOps is a framework for managing cloud-based infrastructure, taking lessons from DevOps and modern application development methodologies. It uses Git as a single source of truth for configuration, automating processes to match the state described in the repository. This approach provides faster deployments, error resolution, and auditing benefits. Argo is a collection of tools that can be used together or independently to implement GitOps best practices, including Argo Workflows, Argo CD, and Argo Rollouts. These tools provide features such as workflow engines, continuous deployment pipelines, and rollout management for safely moving new deployments into production. Argo Events handles events and takes automated action with Kubernetes, providing flexibility in automating processes with preferred tools. The project has gained over 25,000 GitHub stars and is currently the 6th most active CNCF project.
