Management host for installing the cluster
A management host (referred to as kubesprayhost going forward) is an additional Ubuntu 20 LTS host to install your cluster. It is not a member node in the cluster.
Note: We recommend that you use a host machine that is running macOS, Linux or WSL (Windows Subsystem for Linux) to perform the cluster installation.
The rest of the document is based on kubesprayhost running Ubuntu 20 LTS, using a service account. Install required tools on kubesprayhost
Git is a version control system that we use to clone the Kubespray repository. It is typically pre-installed on most Linux systems.
Docker is an open platform that packages software into standardized units called containers that have everything the software needs to run including libraries, system tools, code, and runtime. Install Docker with the following command:
sudo snap install docker
