```
The Kubernetes API currently manages 3 main resources: tasks, replicationControllers, and services. Tasks correspond to colocated groups of [Docker containers](http://docker.io/) with shared volumes, as supported by [Google Cloud Platform’s container-vm images](https://developers.google.com/compute/docs/containers) . Singleton tasks can be created directly via the /tasks endpoint. Sets of tasks may created, maintained, and scaled using replicationControllers. Services create load-balanced targets for sets of tasks.
```
It doesn’t use docker as container runtime. And also the pods were also called `tasks`.
