 A _container runtime_ is software that executes containers and manages container images on a node. Today, the most widely known container runtime is [Docker](https://www.docker.com/), but there are other container runtimes in the ecosystem, such as [rkt](https://coreos.com/rkt/), [containerd](https://containerd.io/), and [lxd](https://linuxcontainers.org/lxd/). Docker is by far the most common container runtime used in production Kubernetes environments, but Docker’s smaller offspring, containerd, may prove to be a better option. This post describes using containerd with Kubernetes.

 Our current plan is to remove dockershim from the Kubernetes codebase soon.
 We are looking for feedback from you whether you are ready for dockershim
 removal and to ensure that you are ready when the time comes.
