What technology does Google Cloud Deploy utilize for rendering Kubernetes-native applications?

Google Cloud Deploy utilizes Skaffold for rendering Kubernetes-native applications. Skaffold is a command-line tool that facilitates continuous development for Kubernetes applications. It manages various aspects of the development workflow, including building images, deploying to Kubernetes, and managing the lifecycle of applications.

Skaffold streamlines the process by supporting a variety of tools and processes, which can be configured to suit the needs of developers and their specific environments. This makes it especially effective for rendering Kubernetes-native applications since it integrates seamlessly with the Kubernetes ecosystem and provides the necessary tooling to automate the deployment and development workflow.

The other options, while relevant to Kubernetes and cloud-native development, serve different purposes. For instance, Helm is a package manager similar to APT or YUM, designed for managing Kubernetes applications through charts. Kustomize allows users to customize Kubernetes YAML configurations declaratively. kpt is focused on managing Kubernetes resource configurations as packages. While these tools contribute to the Kubernetes development experience, Skaffold is particularly tailored for the continuous development pipeline and is deeply integrated into the workflows of Kubernetes application deployment, making it the correct choice for this question.
