Which tool allows for continuous delivery on Kubernetes using GitOps?

The tool that facilitates continuous delivery on Kubernetes using GitOps principles is Argo CD. It is specifically designed to manage Kubernetes applications by continuously monitoring your Git repository for changes and automatically synchronizing those changes to the Kubernetes cluster. This enables a declarative approach to application deployment, where the desired state of the application is stored in Git, and Argo CD ensures that the actual state in the cluster matches the declared state in the repository.

Argo CD supports GitOps methodologies by allowing teams to manage configurations and deployments through version-controlled files. By using a Git repository as the single source of truth, development and operations teams can collaborate more effectively, as every change to the application is tracked, reviewed, and rolled back if necessary, directly through the Git workflows they are familiar with.

In contrast, while other tools mentioned can assist in CI/CD pipelines or application development, they either do not fully embody the GitOps model as pioneered by Argo CD or focus on other aspects of the delivery process. For instance, Google Cloud Build is more focused on building images and running CI pipelines rather than continuous deployment specifically tied to GitOps. Tekton provides a framework for building CI/CD systems, and Skaffold aids in local development for Kubernetes applications but does not directly manage
