ArgoCD is a lightweight tool designed for deploying applications to Kubernetes clusters by using Git as the single source of truth for declarative infrastructure and applications, which simplifies the management of microservice applications. It constantly monitors the configuration files in a Git repository and ensures that the actual state of the Kubernetes cluster matches these configurations, facilitating GitOps practices. The article outlines the steps to implement ArgoCD, including its installation, accessing the API server, adding applications, and deploying them. ArgoCD supports integration with various tools such as SSO providers, Prometheus for metrics collection, and Kube-Watch for notifications, enhancing its functionality in managing releases and tracking changes. Moreover, it offers a user-friendly UI for managing applications and pipelines, while integrations with tools like Earthly can further streamline CI/CD workflows.
