rkt is an application container engine developed for modern production cloud-native environments. It features a pod-native approach, a pluggable execution environment, and a well-defined surface area that makes it ideal for integration with other systems.
The core execution unit of rkt is the pod, a collection of one or more applications executing in a shared context (rkt’s pods are synonymous with the concept in the Kubernetes orchestration system).
This is free and open source software. However, it’s no longer actively developed.
Key Features
- Composable – a single binary that integrates with init systems, scripts, and complex devops pipelines. Containers take their correct place in the PID hierarchy and can be managed with standard utilities.
- Customizable isolation – pluggable runtime architecture, known as stages.
- Pods built-in – a group of related containers that share resources. This allows for easy stacking of related components, and maps directly to cluster management concepts.
