# 1.20.2-do.0

DigitalOcean Kubernetes (DOKS) is a Kubernetes service with a fully managed control plane, high availability, and autoscaling. DOKS integrates with standard Kubernetes toolchains and DigitalOcean’s load balancers, volumes, CPU and GPU Droplets, API, and CLI.

Starting with DigitalOcean Kubernetes 1.20, containerd is used as the container runtime. Previous releases used Docker. This change reflects the upstream [deprecation of dockershim](https://kubernetes.io/blog/2020/12/02/dockershim-faq/) and [deprecation of Docker as a container runtime](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.20.md#deprecation) in Kubernetes 1.20. Docker is still installed on worker nodes, so as not to impact any user workloads (for example, image building) that depend on it.
