## Abstract ## Abstract
The `crio` daemon is intended to provide the [CRI](https://github.com/kubernetes/community/blob/master/contributors/devel/container-runtime-interface.md) socket needed for Kubernetes to use for automating deployment, scaling, and management of containerized applications (See the document for [configuring kubernetes to use CRI-O](./kubernetes.md) for more information on that). The `crio` daemon is intended to provide the [CRI](https://github.com/kubernetes/community/blob/master/contributors/devel/container-runtime-interface.md) socket needed for Kubernetes to use for automating deployment, scaling, and management of containerized applications (See the document for [configuring kubernetes to use CRI-O](./kubernetes.md) for more information on that).
Therefore the `crioctl` command line is a client that interfaces to the same grpc socket as the kubernetes daemon would, for talking to the `crio` daemon. Therefore the [crictl](https://github.com/kubernetes-incubator/cri-tools) command line is a client that interfaces to the same grpc socket as the kubernetes daemon would, for talking to the `crio` daemon.
In many ways `crioctl` is only as feature rich as the Kubernetes CRI requires. In many ways [crictl](https://github.com/kubernetes-incubator/cri-tools) is only as feature rich as the Kubernetes CRI requires.
There are additional tools e.g. `kpod` and [`buildah`](https://github.com/projectatomic/buildah) that provide a feature rich set of commands for all operational needs in a Kubernetes environment.
