In this lab, you will install Kubernetes and configure it to use containerd. You will be provided with one server. On this server, you will install and configure Kubernetes and configure it to use containerd for container management.
You will not be required to create a cluster. Having the software installed and ready for use as a cluster controller will be sufficient.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Log In to the Provided Server
