Kubernetes lacks built-in mechanisms for automating app deployment, but GitOps-powered continuous delivery (CD) workflows can fill this gap. Flux and Argo CD are two popular tools for implementing GitOps with Kubernetes, continually syncing the states of Kubernetes objects against declarative config files stored in your repository. Both tools provide many benefits for developers and cluster operators, but choosing between them depends on factors such as architecture, ease of use, and multi-tenancy support. Flux emphasizes simplicity and seamless integration with Kubernetes, while Argo CD offers a richer user interface, application-centric management, and advanced features like multi-cluster support and self-healing.
