## Compute Instances
The compute instances in this lab will be provisioned using [Ubuntu Server](https://www.ubuntu.com/server) 18.04, which has good support for the [containerd container runtime](https://github.com/containerd/containerd). Each compute instance will be provisioned with a fixed private IP address to simplify the Kubernetes bootstrapping process.
