# 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 ``` ```` NAME ZONE MACHINE_TYPE INTERNAL_IP STATUS controller0 us-central1-f n1-standard-1 10.240.0.20 RUNNING controller1 us-central1-f n1-standard-1 10.240.0.21 RUNNING controller2 us-central1-f n1-standard-1 10.240.0.22 RUNNING etcd0 us-central1-f n1-standard-1 10.240.0.10 RUNNING etcd1 us-central1-f n1-standard-1 10.240.0.11 RUNNING etcd2 us-central1-f n1-standard-1 10.240.0.12 RUNNING worker0 us-central1-f n1-standard-1 10.240.0.30 RUNNING worker1 us-central1-f n1-standard-1 10.240.0.31 RUNNING worker2 us-central1-f n1-standard-1 10.240.0.32 RUNNING ```` > All machines will be provisioned with fixed private IP addresses to simplify the bootstrap process. To make our Kubernetes control plane remotely accessable 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 146.148.34.151 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. ### etcd ``` gcloud compute instances create etcd0 \ --boot-disk-size 200GB \ --can-ip-forward \ --image-project ubuntu-os-cloud \ --image ubuntu-1604-xenial-v20160627 \ --machine-type n1-standard-1 \ --private-network-ip 10.240.0.10 ``` ``` gcloud compute instances create etcd1 \ --boot-disk-size 200GB \ --can-ip-forward \ --image-project ubuntu-os-cloud \ --image ubuntu-1604-xenial-v20160627 \ --machine-type n1-standard-1 \ --private-network-ip 10.240.0.11 ``` ``` gcloud compute instances create etcd2 \ --boot-disk-size 200GB \ --can-ip-forward \ --image-project ubuntu-os-cloud \ --image ubuntu-1604-xenial-v20160627 \ --machine-type n1-standard-1 \ --private-network-ip 10.240.0.12 ``` ### Kubernetes Controllers ``` gcloud compute instances create controller0 \ --boot-disk-size 200GB \ --can-ip-forward \ --image-project ubuntu-os-cloud \ --image ubuntu-1604-xenial-v20160627 \ --machine-type n1-standard-1 \ --private-network-ip 10.240.0.20 ``` ``` gcloud compute instances create controller1 \ --boot-disk-size 200GB \ --can-ip-forward \ --image-project ubuntu-os-cloud \ --image ubuntu-1604-xenial-v20160627 \ --machine-type n1-standard-1 \ --private-network-ip 10.240.0.21 ``` ``` gcloud compute instances create controller2 \ --boot-disk-size 200GB \ --can-ip-forward \ --image-project ubuntu-os-cloud \ --image ubuntu-1604-xenial-v20160627 \ --machine-type n1-standard-1 \ --private-network-ip 10.240.0.22 ``` ### Kubernetes Workers ``` gcloud compute instances create worker0 \ --boot-disk-size 200GB \ --can-ip-forward \ --image-project ubuntu-os-cloud \ --image ubuntu-1604-xenial-v20160627 \ --machine-type n1-standard-1 \ --private-network-ip 10.240.0.30 ``` ``` gcloud compute instances create worker1 \ --boot-disk-size 200GB \ --can-ip-forward \ --image-project ubuntu-os-cloud \ --image ubuntu-1604-xenial-v20160627 \ --machine-type n1-standard-1 \ --private-network-ip 10.240.0.31 ``` ``` gcloud compute instances create worker2 \ --boot-disk-size 200GB \ --can-ip-forward \ --image-project ubuntu-os-cloud \ --image ubuntu-1604-xenial-v20160627 \ --machine-type n1-standard-1 \ --private-network-ip 10.240.0.32 ```
