Rkt

Rkt, pronounced "rocket," is a container engine developed by CoreOS that allows applications to run in isolated environments called containers. Containers package an application with everything it needs to run, making it easier to deploy consistently across different systems. Rkt focuses on security and simplicity, enabling users to run applications in a more streamlined way. Unlike other container systems, Rkt follows a pod-oriented approach, grouping containers together, which is similar to how Kubernetes manages them. Overall, Rkt is designed to facilitate the development and management of cloud-native applications.
