Argo CD is an open-source GitOps continuous delivery tool developed by Intuit that automates Kubernetes deployments by continuously monitoring and synchronizing the desired state in Git repositories with the actual state of the infrastructure. It is maintained by the community as part of the Argo Project and is known for simplifying complex application rollouts, enhancing deployment speed, and ensuring configuration consistency. While Argo CD excels in automating the synchronization of infrastructure, it has limitations in governance, such as limited role-based access control and audit trails, and challenges in implementing advanced deployment strategies and multi-cluster management. Integrating Argo CD with Harness can address these limitations by offering enhanced governance, scalable multi-cluster management, and integrated quality checks, making it a robust solution for enterprise organizations looking to optimize their CI/CD pipelines and software delivery processes.
