# Cloud Infrastructure Provisioning - Google Cloud Platform
|
|
|
|
This lab will walk you through provisioning the compute instances required for running a H/A Kubernetes cluster. A total of 6 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.
|
|
|
|
## Networking
|
|
|
|
Set the region and zone to us-central1:
|
|
|
|
```
|
|
gcloud config set compute/region us-central1
|
|
```
|
|
|
|
```
|
|
gcloud config set compute/zone us-central1-f
|
|
```
|
|
Create a Kubernetes network:
|
|
|
|
```
|
|
gcloud compute networks create kubernetes --mode custom
|
|
```
|
|
|
|
Create a subnet for the Kubernetes cluster:
|
|
|
|
```
|
|
gcloud compute networks subnets create kubernetes \
|
|
--network kubernetes \
|
|
--range 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-ssh kubernetes 0.0.0.0/0 tcp:22
|
|
```
|
|
|
|
### Kubernetes Public 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.
|
|
|
|
