# 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](https://cloud.google.com/) (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 a Custom Network
```
gcloud compute networks create kubernetes --mode custom
```
```
NAME MODE IPV4_RANGE GATEWAY_IPV4
kubernetes custom
```
Create a subnet for the Kubernetes cluster:
```
gcloud compute networks subnets create kubernetes \
--network kubernetes \
--range 10.240.0.0/24 \
--region us-central1
```
```
NAME REGION NETWORK RANGE
kubernetes us-central1 kubernetes 10.240.0.0/24
```
### Firewall Rules
```
gcloud compute firewall-rules create kubernetes-allow-icmp \
--allow icmp \
--network kubernetes \
--source-ranges 0.0.0.0/0
```
```
gcloud compute firewall-rules create kubernetes-allow-internal \
--allow tcp:0-65535,udp:0-65535,icmp \
--network kubernetes \
--source-ranges 10.240.0.0/24
```
```
gcloud compute firewall-rules create kubernetes-allow-rdp \
--allow tcp:3389 \
--network kubernetes \
--source-ranges 0.0.0.0/0
```
```
gcloud compute firewall-rules create kubernetes-allow-ssh \
--allow tcp:22 \
--network kubernetes \
--source-ranges 0.0.0.0/0
```
```
gcloud compute firewall-rules create kubernetes-allow-healthz \
--allow tcp:8080 \
--network kubernetes \
--source-ranges 130.211.0.0/22
```
```
gcloud compute firewall-rules create kubernetes-allow-api-server \
--allow tcp:6443 \
--network kubernetes \
--source-ranges 0.0.0.0/0
```
```
gcloud compute firewall-rules list --filter "network=kubernetes"
```
```

kubernetes-allow-rdp kubernetes 0.0.0.0/0 tcp:3389
kubernetes-allow-ssh kubernetes 0.0.0.0/0 tcp:22
```
## 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 kubernetes
```
```
NAME REGION ADDRESS STATUS
kubernetes us-central1 XXX.XXX.XXX.XXX 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.
