# Cloud Infrastructure Provisioning
|
|
|
|
Kubernetes can be installed just about anywhere physical or virtual machines can be run. In this lab we are going to focus on Google Cloud Platform (IaaS).
|
|
|
|
This lab will walk you through provisioning the compute instances required for running a H/A Kubernetes cluster. A total of 9 virtual machines will be created.
|
|
|
|
After completing this guide you should have the following compute instances:
|
|
|
|
```
|
|
gcloud compute instances list
|
|
```
|
|
|
|

> All machines will be provisioned with fixed private IP addresses to simplify the bootstrap process.
|
|
|
|
To make our Kubernetes control plane remotely accessible, a public IP address will be provisioned and assigned to a Load Balancer that will sit in front of the 3 Kubernetes controllers.
|
|
|
|
## Create the Kubernetes Public IP Address
|
|
|
|
Create a public IP address that will be used by remote clients to connect to the Kubernetes control plane:
|
|
|
|
```
|
|
gcloud compute addresses create kubernetes
|
|
```
|
|
|
|
```
|
|
gcloud compute addresses list
|
|
```
|
|
```
|
|
NAME REGION ADDRESS STATUS
|
|
kubernetes us-central1 104.197.132.159 RESERVED
|
|
```
|
|
|
|
## Provision Virtual Machines
|
|
|
|
All the VMs in this lab will be provisioned using Ubuntu 16.04 mainly because it runs a newish Linux Kernel that has good support for Docker.
|
